Do you know what DMARC security is? DMARC stands for Domain-based Message Authentication, Reporting & Conformance. It’s a security and email authentication protocol that allows organizations to protect their domain from being spoofed by email phishing scams. It’s also used by email service providers and ISPs to detect and prevent fraud.

If you haven’t heard of it yet, don’t worry—it’s actually pretty easy to understand.

What is DMARC Security? 

DMARC is an email authentication standard that helps you prevent spoofing, phishing, and other email-based attacks. It works by allowing you to define a policy that dictates how your domain should handle messages with invalid sender addresses.

The first step in setting up DMARC is registering your domain name with SPF, which allows you to control what IP addresses can send emails on behalf of your company. You’ll also need to set up DKIM and start reporting email abuse through spam reports or abuse reports.

Using SPF in combination with DMARC Security

When an ISP receives an email with SPF records attached, they check them against their own DNS records for the sender’s domain name. If there are no SPF records or if they don’t match up with what they have on file, then they reject the message because it could be spam or spoofed content from another source (like a phishing attack).

When used in combination with DMARC security, unauthorized emails can be blocked out by the sender before it reaches the client. 

Using DKIM in combination with DMARC Security

With DKIM, a domain owner registers with a public key provider and publishes a public key in DNS records. When an email is sent from an email server that uses DKIM, the sending server adds a signature to the message. The signature contains the domain of the sender (for example, “”) and a cryptographic hash of the message headers and body. Receivers use this information to verify that an email message was not modified during transit.

DKIM alone does not protect against spoofing or phishing attacks because it does not authenticate the identity of the sender in any way. To address this issue and prevent spoofing, DMARC security is recommended.

What is our advice?

Going into 2023, we only want to advise the very best for your domain. For enhanced protection, it is advisable to set up your domain with both DKIM and SPF in combination with DMARC. This will also help you receive reports on any delivery failures that may have occurred if you’re on an enforced DMARC policy. 

Why is DMARC security important?

By default, most email servers send a “pass” or “fail” verdict on emails they receive, but this can be easily spoofed by spammers and phishers. DMARC allows you to authenticate the legitimacy of emails coming from your domain name and specify how those messages should be handled if they fail authentication or fail to pass SPF and DKIM checks.

How to start with DMARC security for beginners?

If you are new to DMARC security, here’s how you can start: 

  1. Use a hosted DMARC solution – A hosted DMARC solution will help you manage your protocol on a cloud-based dashboard without having to access your DNS to make updates or edits. This simplest the authentication process drastically, and is amazing for both beginners and experts who want to save time and effort.

Information Security and Cyber Security are two separate fields, but with way too much overlap there to create confusion in understanding the concepts of each. This post takes a deep dive into an overview of information security vs cyber security so that you can make an informed decision regarding your knowledge and levels of protection for your private or public sector organization.

What is Information Security?

Information Security (also known as InfoSec) is the process of protecting information assets from unauthorized access, use, modification, disclosure, and destruction. It encompasses all facets of protecting the confidentiality, integrity, and availability of the information.

The purpose of information security is to help organizations protect their intellectual property, customer data, trade secrets, proprietary information, and other assets–such as resources of value–from being accessed, used, or disclosed by unauthorized parties with malicious intent.

In today’s tech-driven world, where people are constantly sharing information online via email, social media accounts, and more, companies must implement strong information security programs so that they can protect their data and prevent it from being hacked. Therefore, mitigating the risk of losing customers and brand integrity.

Information security can be achieved through the use of security measures like encryption keys, access control and email authentication.

For example, a company may have an online store that sells its products, but it needs to protect the data that identifies customers and their orders. The company’s information security measures include encrypting all of its transmitted information, developing and enforcing policies around password use and file sharing, and monitoring all access to network resources.

What is Cyber Security?

Cyber Security is the process of protecting networks, systems, and data from unauthorized access, modification, and destruction. It is an umbrella term for a group of related technologies and disciplines that help to prevent unauthorized access to networks, systems, and data.

Cybersecurity can be broken down into three main categories; risk analysis, detection and response, and protection.

  • Risk analysis involves identifying potential risks to your organization’s networks and systems so you can prioritize where to spend your cybersecurity budget.
  • Detection involves monitoring activity on your network to detect any unauthorized activity or activity that might indicate a breach has occurred.
  • Protection involves protecting your information systems from being attacked by hackers using various methods such as firewalls and intrusion detection systems (IDSs).

For organizations to be successful in an increasingly digital world, they must ensure that their cyber security practices are robust enough to prevent, identify, and respond to cyber threats to maintain the security of data and networks.

Cyber security can also help prevent corporate espionage in other ways. For example, if someone inside your company tries to access another employee’s account on your network, they will be blocked by the firewall until they have been authenticated and authorized by the proper authorities.

Information Security vs Cyber Security: The Differences

Information security and cyber security are two distinct fields of information technology that complement each other.

These two disciplines often overlap in their practice as technologies evolve but each should be given consideration individually for its purpose or applications.

Let’s read how they differ from one another in the Information Security vs Cyber Security comparison shared below:

Protection Parameters

Cyber security protects cyberspace from threats, while information security is the protection of overall data from threats.

Cyber security focuses on the protection of networks, devices, and systems against cyber attacks. It also aims to protect individuals against identity theft, fraud, and other online crimes. Cyber security is concerned with protecting users’ privacy through encryption in their communications and data. This means that cyber security does not protect companies’ intellectual property or provide for employee privacy.

Information security focuses on protecting organizations’ data from unauthorized access by employees or outsiders. It is concerned with ensuring that confidential information is stored securely without falling into the hands of third parties who could use it inappropriately or even cause harm to its owner. Information security can be divided into three categories: physical (e.g., locking away documents), logical (e.g., encrypting sensitive data), and administrative controls (e.g., changing passwords periodically).

A good way to think about these two approaches is to consider how they relate to each other in terms of risks. Cybersecurity focuses on risk management and controls that are used to prevent harm from occurring within cyberspace; whereas information security focuses on risk management and controls for managing threats to individual systems (or organizations).

Security Scope

Cyber security is the process of protecting information in cyberspace. It deals with protecting the data or information that resides in a computer system or network from being compromised by hackers, viruses, and other malicious software. Since cybercrime is a global threat, businesses often choose cyber security localization to strengthen the security of their web properties.

Information security on the other hand is the broader umbrella term that includes all of the techniques used to protect information from unauthorized access, use, disclosure, modification, or destruction in any form. It protects data and information regardless of whether they are stored on a hard drive in an office building, or on an external server in another country.

The key takeaway here is that Cyber Security provides defense mechanisms within the cyber realm only while Information Security looks at protecting data regardless of where it resides or how it is used (i.e., at home or in business).

Threat Shielding

Cybersecurity is concerned with the protection of computer networks and technologies from cyberattacks, cyberterrorism, and other kinds of attacks that use computers or networks as their means. On the other hand, information security focuses on protecting data in whatever format it’s stored.

For example, if you’re trying to protect your email messages from being stolen by hackers, you’re dealing with cybersecurity. If you’re trying to protect your family’s health records from getting into the wrong hands, you’re dealing with information security.


Cybersecurity deals with those threats in cyberspace—those that occur when you’re using your computer or mobile device, or even when you’re connected to the Internet. Information security deals with any form of threat related to the protection of any sort of data—whether it’s physical data like financial records or other types of information like email accounts.

Combat Approach

Cybersecurity refers to the technology that protects information systems from cyber-attacks. Information security refers to the techniques that companies use to protect their data and systems from unauthorized access, disclosure of confidential information, or disruption by hackers.

➜ Cybersecurity combats:

Cybercrime – a broad term that describes any illegal activity that happens online. Some cybercrimes include hacking, phishing, identity theft, and other crimes.

Cyber fraud – a digital scam committed through the internet or email, e.g credit card fraud (where someone steals your credit card information and uses it to make purchases online.)

➜ Information security combats:

Unauthorized access – when a person or entity accesses information without authorization. An example of unauthorized access is someone who steals data on a server or network.

Disclosure modification – when an attacker intentionally modifies the data in such a way that it can be used against the original owner.

Disruption – the act of interfering with normal operations of a system to deny service to legitimate users, causing outages and delays in orders being fulfilled.

Therefore, the difference between information security and cyber security is like the difference between guarding a castle with a sword versus using a gun to defend it—both are necessary for keeping your castle safe, but one is more effective than the other depending on your circumstances. This makes both of them an important aspect of any organization’s overall protection strategy.

Defense Activation

Cybersecurity is the first line of defense against cyber threats. It’s what we call “the good guys” when they’re trying to prevent hackers from infiltrating your computer or stealing your personal information.

Information security is what happens when cyber security fails—when it is breached and malicious code gets past the firewall and into your system. Information security helps you prevent breaches and recover quickly from them so that you can continue to use your system without interruption.

Because cyber security deals with external threats, it’s often referred to as “outside-in” protection, while information security is more of an “inside-out” approach that focuses on both internal and external risks.

Information Security vs Cyber Security: The Overlaps

Information security and cybersecurity are two separate, but related, fields. It’s because they both focus on protecting the confidentiality, integrity, and availability of sensitive information from unauthorized access or use.

There are some key overlapping concerns in this space:

  • both fields look at threats to data security that might come from any source (including human error)
  • both fields look at protecting data as it flows through networks or devices
  • both fields look at securing devices so that they’re not vulnerable to attack by hackers or other bad actors

To sum it up, information security provides the technological components needed to protect data while cyber-security provides a framework for how those technical components should be used by organizations that want their data protected from attackers.

Email Security as a Part of Information Security

A proper information security framework also incorporates email security since most information in a corporate setup is exchanged via emails. 

To secure your emails against spoofing and phishing threats, A DMARC analysis tool is imperative. Implement email authentication protocols at your organizations to safguard your email communications today!

Even the most experienced and well-prepared company can be caught off guard by an email compromise. That’s why it’s essential to build an effective email security compliance model.

What is Email Security Compliance?

Email security compliance is the process of monitoring, maintaining, and enforcing policies and controls to ensure the confidentiality of electronic communications. This can be done via regular email audits or ongoing monitoring efforts.

Every organization should have a documented Security Compliance Model (SCM) that outlines its policies, procedures, and activities related to email security compliance. This ensures that no communication violations occur within your organization and helps retain business partners who may be wary of companies with poor security practices.

Understanding The Email Security Compliance Regulations for Businesses

Email security compliance laws serve as a legal framework for ensuring the security and privacy of the information stored in email. These laws are enforced by various national governments and are a growing concern for businesses of all shapes and sizes.

Below, we have given a brief overview of the requirements imposed on businesses that handle email communication, along with a general overview of the various legal frameworks applicable to comply with for building a proper email security compliance for your business.


The Health Insurance Portability and Accountability Act (HIPAA) and the Security Standards for Federal Information Systems, 2nd Edition (SOC 2), FedRAMP, and PCI DSS are all regulations that require organizations to protect the privacy and security of electronically protected health information (ePHI). ePHI is any information that is transmitted electronically between covered entities or business associates.

The laws require covered entities to implement policies, procedures, and technical controls appropriate to the nature of the data they process, as well as other safeguards necessary to carry out their responsibilities under HIPAA and SOC 2. These regulations apply to all entities who transmit or receive PHI in electronic form on behalf of another entity; however, they also apply to all business associates and other entities who receive PHI from a covered entity.

To Which Business Does This Regulation Apply?

This regulation applies to any business that collects, stores, or transmits PHI (Protected Health Information) electronically. It also applies to any business that is involved in the provision of a Covered Electronic Health Record (eHealth Record) or other covered health care services electronically. These regulations are designed to protect both patient privacy and the security of patient data from unauthorized access by third parties.


The General Data Protection Regulation (GDPR) is a regulation implemented by the European Union. It is designed to protect the personal data of EU citizens, and it has been called “the most important privacy law in a generation”.

GDPR requires businesses to be transparent about how they use customer data, as well as provide clear policies on how they handle that data. It also requires businesses to disclose what information they collect and store about customers, and offer easy ways for individuals to access that information. In addition, GDPR prohibits businesses from using personal data for purposes other than those for which it was collected.

To Which Business Does This Regulation Apply?

It applies to all companies that gather data in the EU, and it requires companies to have explicit consent from those whose personal information they collect. GDPR also comes with fines for non-compliance, so you must get your ducks in a row before you start collecting any personal information.


CAN-SPAM is a federal law passed by Congress in 2003 that requires commercial business emails to include certain information about their origin, including the sender’s physical address and phone number. The law also requires commercial messages to include a return address, which must be an address within the sender’s domain.

The CAN-SPAM Act was later updated to include stricter requirements for commercial emails. The new rules require that email senders identify themselves clearly and accurately, provide a legitimate return address, and include an unsubscribe link at the bottom of each email.

To Which Business Does This Regulation Apply?

The CAN-SPAM Act applies to all commercial messages, including those sent by businesses to consumers and vice versa, as long as they meet certain requirements. The regulations are meant to protect businesses from spamming, which is when someone sends a message with the intention of getting you to click on a link or open an attachment. The law also protects consumers from spam that’s sent by companies trying to sell them something.

How To Build An Email Security Compliance Model For Your Business

The email security compliance model is designed to verify that an organization’s servers and email applications comply with applicable laws, industry-wide standards, and directives. The model helps organizations to establish policies and procedures that provide for the collection and protection of customer data through the detection, prevention, investigation, and remediation of potential security incidents.

Below you will learn how to build a model that helps with email security as well as tips and advanced technologies to go beyond compliance.

1. Use Secure Email Gateway

An email security gateway is an important line of defense for protecting your company’s email communications. It helps ensure that only the intended recipient receives the email, and it also blocks spam and phishing attempts.

You can use the gateway to manage the flow of information between your organization and its customers. As well as take advantage of features like encryption, which helps protect sensitive information sent over email by encrypting it before it leaves one computer and decrypting it on its way to another computer. This can help prevent cybercriminals from being able to read the contents of emails or attachments sent between different computers or users.

A secure email gateway can also provide features such as spam filtering and archiving—all of which are essential for maintaining an organized and compliant atmosphere in your company.

2. Exercise Post-Delivery Protection

There are several ways to build an email security compliance model for your business. The most common method is to use the model to identify potential risks, and then apply Post-Delivery Protection (PDP) to those risks.

Post-delivery protection is the process of verifying that an email has been delivered to its intended recipient. This includes ensuring that the recipient can log in to their email client software and check for the message, as well as confirming that the email hasn’t been filtered by spam filters.

Post-delivery protection can be achieved by having a secure network or server where your emails are stored and then encrypting them before they are delivered to the intended recipients. It is important to note that only an authorized person should have access to these files so they can be decrypted by them only.

3. Implement Isolation Technologies

An email security compliance model is built by isolating all endpoints of your users and their web traffic. Isolation technologies work by isolating all of a user’s web traffic in a cloud-based secure browser. This means that emails sent through isolation technology are encrypted on the server-side and decrypted on the client-side in an ‘isolated’ station.

Therefore, no external computers can access their emails, and they can’t download any malicious programs or links. This way, even if someone clicks on a link in an email that contains malware, the malware won’t be able to infect their computer or network (as the malicious link will open in a read-only form).

Isolation technologies make it easy for companies to comply with regulations like PCI DSS and HIPAA by implementing secure email solutions that use host-based encryption (HBE).

4. Create Effective Spam Filters

Email filtering involves checking email messages against a list of rules before they are delivered to the receiving system. The rules can be set up by users or automatically based on certain criteria. Filtering is typically used to verify that messages sent from certain sources are not malicious or contain any unexpected content.

The best way to create an effective spam filter is by analyzing how spammers use techniques that make their messages difficult to detect before they reach recipients’ inboxes. This analysis should help you develop filters that will identify spam and prevent it from reaching the inbox.

Fortunately, there are some solutions available (like DMARC) that automate much of this process by allowing businesses to define specific rules for each message so that only the ones that match those rules get processed by the filters.

5. Implement Email Authentication Protocols

The DMARC standard is an important step toward ensuring that your users get the messages they expect from your business and that sensitive information never reaches unintended hands.

It’s an email authentication protocol that enables domain owners reject messages that fail to meet certain criteria. This can be used as a way to prevent spam and phishing, but it’s also useful for preventing deceptive emails from being sent to your customers.

If you are building an email security compliance model for your business, you need DMARC to help protect your brand from being tarnished by malicious emails sent from outside sources that may attempt to impersonate the business name or domain to defraud your loyal customers. .

As a customer of a business with DMARC-enabled email messages, you can rest assured that you’re receiving legitimate communications from the business.

6. Align Email Security with an Overarching Strategy

The overarching strategy of your email security compliance program is to ensure that your organization complies with all relevant government regulations. These include regulations related to the following areas: sender IDs, opt-ins, opt-outs, and request processing time.

To achieve this, you need to develop a plan that addresses each of these areas separately and then integrate them in such a way that they are mutually supporting.

You should also consider differentiating your email strategy across different regions based on the distinct policies each has. For example, in the US, there are many different regulations regarding spamming which require different means of implementation than those required in other countries such as India or China where spamming regulations are less stringent.

Check out our corporate email security checklist to secure your corporate domains and systems. 

Building An Email Security Compliance Model For Your Business: Additional Steps

  • Develop a data collection plan that includes the types of information you’d like to collect, how often you’d like to collect it, and how long it should take to collect it
  • Train employees on how to use email safely and securely by instituting policies, procedures, and training modules about the proper use of email in their workplace.
  • Evaluate your current email security measures to see if they are up-to-date with industry best practices, and consider upgrading if necessary.
  • Determine what kind of human resources data needs to be kept private or confidential and how it will be communicated to your employees, partners, and vendors, including any third parties involved in creating content for your website or social media channels.
  • Create a list of all employees who have access to sensitive/confidential information and develop a plan for monitoring their use of email communications tools.

Who Is Responsible For Email Security Compliance In Your Business?

IT Managers – The IT manager is responsible for the overall email security compliance of their organization. They are the ones who make sure that the company’s security policies are followed and that all employees have been trained on them.

sysadmins – Sysadmins are responsible for installing and configuring email servers as well as any other IT infrastructure that may be necessary to run a successful email system. They must understand what type of data is being stored, who has access to it, and how it will be used.

Compliance Officers – They are responsible for ensuring that the company complies with all laws regarding email security compliance.

Employees – Employees are responsible for following the company’s email security policies and procedures, as well as any additional instructions or guidance from their manager or supervisor.

Third party service providers – You can outsource your email’s security to third parties that will save you both time and money. For example, a third party DMARC managed service provider can help you implement your protocols within a few minutes, manage and monitor your DMARC reports, troubleshoot errors and provide expert guidance to gain compliance easily.

2021 has been quite an eventful year when it comes to email security and authentication. From major ransomware attacks that ended up costing businesses billions of dollars to COVID-19 vaccination phishing lures in the form of fake emails, security professionals had a lot to deal with.

Today we are looking back at the major email security attacks of 2021, talking about what the future holds, and sharing some handy tips on tackling threats in 2022.

Major email security attacks in 2021

1. Direct-domain spoofing

Spoofing attacks continue to rise as we progress into 2022, with attackers impersonating brands including but not limited to well-known industry names like DHL, Microsoft, and Amazon.

2. Phishing attacks

The FBI’s Internet Crime Complaint Center received the most complaints against phishing attacks in 2021.

3. Ransomware

Using phishing as the most common attack vector, several systems were affected by malware and ransomware files this year.

4. Man-in-the-middle attacks

SMTP email security loopholes are easily exploited by Man-in-the-middle attackers to intercept and eavesdrop on email communications.

How to build cyber resilience against these attacks?

Deploying SPF, DKIM, and DMARC

DMARC can help you minimize phishing and spoofing attacks. It also acts as the first line of defense against ransomware. Other benefits of DMARC include improved email deliverability, reduced spam complaints, and boosts your domain’s reputation.


If your client’s ESP supports BIMI, it is a good idea to deploy it today. BIMI helps your customers visually identify you in their inbox even before they get around to opening the message.


MTA-STS is an effective solution against MITM attacks, helping secure your emails in transit and overcome SMTP security issues.

What to expect in 2022?

  • With various organized internet crime groups resurfacing in recent times with upgraded tactics, it wouldn’t be a surprise to anyone if the intensity and frequency of email-based attacks increase even further in 2022.
  • Brand impersonations and ransomware attacks will continue to surge as cybercriminals exploit remote working environments. To make situations worse, the cost associated with these attacks is predicted to also rise in the following year.

Final Thoughts

Security experts recommend that organizations take email security more seriously in the years to come, due to the alarming increase in cyberattacks. A popular myth that security professionals are now debunking is that only MNCs and enterprise-level companies need DMARC. This, of course, is not true as in the past year almost 50% of the organizations that were hit by internet attacks were in fact startups and small businesses. 

Another important thing to consider while implementing security standards is that a relaxed policy for your protocols will provide your domain with very little to zero protection.

While social engineering attacks continue to evolve and get more and more complex and undetectable, companies should evolve with them. Email authentication protocols, while there is no silver bullet, definitely reduce the chances of falling prey to email-based attacks and strengthen the overall email security posture at your organization. It also provides deeper insight into attacks and vulnerabilities, reducing the incident response time.

Email spoofing is a growing problem for an organization’s security. Spoofing occurs when a hacker sends an email that appears to have been sent from a trusted source/domain. Email spoofing isn’t a new concept. Defined as “the forgery of an email address header in order to make the message appear to be sent from someone or somewhere other than the actual source,” it has plagued brands for decades. Whenever an email is sent, the From address doesn’t display what server the email was actually sent from—instead it displays whatever domain is entered during the address creation process, thereby raising no suspicion among email recipients.

With the amount of data passing through email servers today, it should come as no surprise that spoofing is an issue for businesses.At the end of 2020,  we found that phishing incidents rose by a staggering 220% compared to the yearly average during the height of global pandemic fears.. Since not all spoofing attacks are carried out on a large scale, the actual number could be much higher. It is 2021, and the problem seems to be only worsening with each passing year. This is why brands are availing of secure protocols to authenticate their emails and steer clear of the malicious intentions of threat actors.

Email Spoofing: What Is It and How Does It Work?

Email spoofing is used in phishing attacks to trick users into thinking the message came from a person or entity they either know or can trust. A cybercriminal uses a spoofing attack to trick recipients into thinking the message came from someone it didn’t. This lets attackers harm you without letting you trace them back. If you see an email from the IRS saying that they sent your refund to a different bank account, it may be a spoofing attack. Phishing attacks can also be carried out via email spoofing, which is a fraudulent attempt to obtain sensitive information such as usernames, passwords and credit card details (PIN numbers), often for malicious ends. The term comes from ‘fishing’ for a victim by pretending to be trustworthy.

In SMTP, when outgoing messages are assigned a sender address by the client application; outbound emails servers have no way to tell if the sender address is legitimate or spoofed. Hence, email spoofing is possible because the email system used to represent email addresses does not provide a way for outgoing servers to verify that the sender address is legitimate. This is why large industry players are opting for protocols like SPF, DKIM and DMARC to authorize their legitimate email addresses, and minimize impersonation attacks.

Breaking Down the Anatomy of an Email Spoofing Attack

Each email client uses a specific application program interface (API) to send email. Some applications allow users to configure the sender address of an outgoing message from a drop- down menu containing email addresses. However, this ability can also be invoked using scripts written in any language. Each open mail message has a sender address that displays the address of the originating user’s email application or service. By reconfiguring the application or service, an attacker can send email on behalf of any person.

Let’s just say that now it is possible to send thousands of fake messages from an authentic email domain! Moreover, you don’t have to be an expert in programming to use this script. Threat actors can edit the code according to their preference and begin sending a message using another sender’s email domain. This is exactly how an email spoofing attack is perpetrated.

Email Spoofing as a Vector of Ransomware

Email spoofing paves the way for the spread of malware and ransomware. If you don’t know what ransomware is, it is a malicious software which perpetually blocks access to your sensitive data or system and demands an amount of money (ransom) in exchange for decrypting your data again. Ransomware attacks make organizations and individuals lose tons of money every year and lead to huge data breaches.

DMARC and email authentication also acts as the first line of defense against ransomware by protecting your domain from the malicious intentions of spoofers and impersonators.

Threats Involved for Small, Medium and Large Businesses

Brand identity is vital to a business’s success. Customers are drawn to recognizable brands and rely on them for consistency. But cybercriminals use anything they can to take advantage of this trust, jeopardizing your customers’ safety with phishing emails, malware, and email spoofing activities. The average organization loses between $20 and $70 million a year due to email fraud. It is important to note that spoofing can involve trademark and other intellectual property violations as well, inflicting a considerable amount of damage to a company’s reputation and credibility, in the following two ways:

  • Your partners or esteemed customers can open a spoofed email and end up compromising their confidential data. Cybercriminals can inject ransomware into their system leading to financial losses, through spoofed emails posing to be you. Therefore the next time they might be reluctant to open even your legitimate emails, making them lose faith in your brand.
  • Recipient email servers can flag your legitimate emails as spam and lodge them in the junk folder due to deflation in server reputation, thereby drastically impacting your email deliverability rate.

Either ways, without an ounce of doubt, your customer-facing brand will be on the receiving end of all complications. Despite the efforts of IT professionals, 72% of all cyber attacks begin with a malicious email, and 70% of all data breaches involve social engineering tactics to spoof company domains – making email authentication practices like DMARC, a critical priority.

DMARC: Your One-Stop Solution against Email Spoofing

Domain-Based Message Authentication, Reporting and Conformance (DMARC) is an email authentication protocol which when implemented correctly can drastically minimize email spoofing, BEC and impersonation attacks. DMARC works in unison with two standard authentication practices- SPF and DKIM, to authenticate outbound messages, providing a way to specify to receiving servers how they should respond to emails failing authentication checks.

Read more about what is DMARC?

If you want to protect your domain from the malicious intentions of spoofers, the first step is to implement DMARC correctly. But before you do so, you need to set up SPF and DKIM for your domain. PowerDMARC’s free SPF and DKIM record generators can aid you in generating  these records to be published in your DNS, with a single click. After successfully configuring these protocols, go through the following steps to implement DMARC:

  • Generate an error-free DMARC record using PowerDMARC’s free DMARC record generator
  • Publish the record in your domain’s DNS
  • Gradually move to a DMARC enforcement policy of p=reject
  • Monitor your email ecosystem and receive detailed authentication aggregate and forensic (RUA/RUF) reports with our DMARC analyzer tool

Limitations to Overcome While Achieving DMARC Enforcement

You have published an error-free DMARC record, and moved to a policy of enforcement, and yet you are facing issues in email delivery? The problem can be far more complicated than you think. If you didn’t already know, your SPF authentication protocol has a limit of 10 DNS lookups. However, if you used cloud-based email service providers and various third-party vendors, you can easily exceed this limit. As soon as you do so, SPF breaks and even legitimate emails fail authentication, leading your emails to land in the junk folder or not being delivered at all.

As your SPF record gets invalidated due to too many DNS lookups, your domain again becomes vulnerable to email spoofing attacks and BEC. Therefore staying under the SPF 10 lookup limit is imperative to ensure  email deliverability. This is why we recommend PowerSPF, your automatic SPF flatenner, that shrinks your SPF record to a single include statement, negating redundant and nested IP addresses. We also run periodical checks to monitor changes made by your service providers to their respective IP addresses, ensuring that your SPF record is always up-to-date.

PowerDMARC assembles a range of email authentication protocols like SPF, DKIM, DMARC, MTA-STS, TLS-RPT and BIMI to give your domain a reputation and deliverability boost. Sign up today to get your free DMARC analyzer.
