Email spoofing is one of the most common entry points for serious email attacks. It fuels business email compromise, spear phishing, and large-scale phishing attempts that trick users into sending money or sharing sensitive data.
Attackers forge the sender address, manipulate email headers, and make fraudulent emails look legitimate. When email authentication is weak, spoofed emails pass through mail servers unnoticed. The damage often shows up later as financial loss, data breaches, or reputational harm.
Managing Sender Policy Framework, DomainKeys Identified Mail, and Domain-based Message Authentication manually is not realistic for modern security teams. Organizations need automated solutions for email spoofing prevention that continuously monitor authentication status, enforce DMARC policies, and stop unauthorized senders at scale.
This guide compares the 10 best automated email spoofing prevention tools for 2026.
What is Automated Email Spoofing Prevention?
Email spoofing prevention starts with email authentication. The core framework includes:
- Sender Policy Framework (SPF).
- DomainKeys Identified Mail (DKIM).
- Domain-based Message Authentication, Reporting, and Conformance (DMARC).
Together, these email authentication protocols help mail servers verify sender domains by checking authorized IP addresses, validating DKIM signatures (public key), and confirming alignment in key email headers to strengthen email spoofing security. That is the foundation for stopping spoofed emails and reducing phishing attacks.
Automation becomes important when SPF, DKIM, and DMARC require ongoing upkeep across multiple sending sources, shared IP addresses, and frequent changes in Microsoft 365, Google Workspace, and third-party mail servers. Instead of relying on manual DMARC report review and ad hoc DNS updates, automated solutions for email spoofing prevention streamline monitoring, highlight unauthorized senders, and support consistent DMARC enforcement while minimizing false positives.
What to Look For in Automated Solutions For Email Spoofing Prevention
Most platforms will claim they “support SPF, DKIM, and DMARC.” That line tells you almost nothing.
What matters is whether the solution reduces the day-to-day grind for security teams while making spoofing protection stricter, not noisier. Use the checks below to separate a reporting tool from an enforcement-ready system.
A quick reality check before you compare vendorsIf any of this sounds familiar, you need automation:
|
The 7 Checks That Matter in 2026
1) Can it move you to DMARC enforcement without breaking legitimate mail?
A tool is not “automated” if it only visualizes DMARC reports. The real test is whether it helps you confidently leave monitoring mode.
Look for proof of an enforcement workflow:
- Clear steps to progress from p=none toward quarantine or reject based on authentication status and real email traffic.
- Guidance that separates misconfiguration from spoofing attempts so you do not punish legitimate emails.
- Controls that reduce operational risk and minimize false positives during DMARC enforcement.
If the platform cannot explain how it gets you to enforcement safely, it is likely a reporting tool with extra labels.
2) Does it surface as the “actual source” behind mail streams?
When attackers forge a sender address, the inbox view can look clean while the email headers tell a different story.
A good solution should make it easy to validate the actual source using:
- Sending domain and sender domains alignment across SPF and DKIM, plus DMARC authentication status.
- Visibility into IP addresses, including shared IP addresses, with quick identification of new or unusual senders.
- Email headers and email metadata that help detect spoofing attempts and suspicious emails.
- Anomaly detection (machine learning) that surfaces deviations in sender behavior patterns and message-level signals.
You should be able to answer, quickly: who sent this, from where, and was it properly authenticated?
3) How well does it handle SPF upkeep and lookup limits?
SPF issues are one of the fastest ways to stall a DMARC implementation.
Instead of asking “does it support Sender Policy Framework?”, use this checklist:
- Will it alert you before SPF breaks due to the 10-lookup limit?
- Can it keep SPF stable as new sending sources are added?
- Does it reduce the chance of legitimate emails failing authentication because of record sprawl?
If SPF is brittle, DMARC records stay cautious, enforcement gets delayed, and spoofed emails keep landing (a common outcome with SPF permerror).
4) Does it help with brand impersonation, not just your main domain?
Did you know? Many spoofing attacks do not use your exact domain. They use look alike domains to deceive recipients and harm customer trust.
Brand protection coverage should include:
- Monitoring for look alike domains and brand impersonation signals.
- Visibility into phishing attempts tied to malicious links and fraudulent emails.
- Practical response cues for domain owners, not just a “domain detected” alert.
This matters because reputational harm happens even when attackers never touch your real sending domain.
5) Can it plug into your existing email security stack?
Think of this as a fit check. The best platform is the one your security teams can actually operationalize.
| Environment you rely on | What “good fit” looks like |
|---|---|
| Microsoft 365 | Works alongside Microsoft Defender workflows and does not duplicate controls. |
| Google Workspace | Clear reporting for Gmail flows and authentication status visibility. |
| SIEM / SOC | SIEM integration and exportable email data for investigations. |
| Email filtering | Complements filtering logic and reduces gaps in advanced threat detection. |
If integration is weak, teams end up switching between tools and missing context during email attacks. In 2026, some teams also look for anomaly signals that can be pushed into SIEM workflows to speed up investigations.
6) Does it reduce work, or does it create a new queue?
Some platforms replace “manual DMARC” with “manual dashboard management.” The better ones reduce noise by prioritizing anomalies and grouping repeat issues automatically.
A truly automated solution should reduce repetitive work like:
- Chasing down unknown senders across business units and third-party platforms.
- Manually correlating DMARC reports with mail servers, sending services, and shared IP addresses.
- Re-reviewing the same failures because the platform does not cluster patterns or highlight the real outliers.
If your team still spends hours every week triaging DMARC reports, the tool is not doing enough of the heavy lifting.
7) Can it prove value in plain language?
Security leaders usually need to justify tools using outcomes, not protocol details.
A strong platform should make it easy to report:
- Reduction in spoofing attacks and email fraud attempts.
- Improvements in email authentication coverage (SPF, DKIM, and DMARC alignment).
- Trends in phishing emails, malicious emails, and suspicious emails.
- Where risk is coming from: sender domains, IP addresses, or specific sending services.
If it cannot explain impact clearly, it will struggle in budget reviews, even if it is technically strong.
| Did you know? Some modern email security platforms use machine learning to analyze email metadata and sender behavior patterns. It can help spot new spoofing techniques faster, but it works best when SPF, DKIM, and DMARC alignment is already clean. |

Here’s what each tool does best, and where it fits in a real DMARC enforcement rollout.
1. PowerDMARC
PowerDMARC focuses on domain-level email authentication visibility, not just inbox-level filtering. Instead of only reacting to suspicious emails after they land, it helps domain owners see how their sending domain is being used across the email ecosystem, including legitimate senders and unauthorized abuse.
That distinction matters when spoofing attacks and business email compromise attempts come from weak or misaligned authentication. Threat actors often forge the sender address, manipulate email headers, and send spoofed emails that look legitimate. If SPF, DKIM, and DMARC are not aligned consistently across sender domains and sending services, mail servers can treat fraudulent emails as normal traffic.
PowerDMARC brings Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) reporting into one place, with portfolio-style visibility and drill-downs. You can identify who is sending on behalf of each domain, spot alignment failures, and isolate unauthorized senders tied to suspicious IP addresses and authentication failures.
It also supports multi-tenant operations through its Partner Program, which is relevant for MSP and MSSP delivery models where delegated access, account separation, and standardized workflows matter.
Key capabilities
- DMARC aggregate and forensic reporting (RUA and RUF)
PowerDMARC processes RUA and RUF report data and presents it in a human-readable format for investigation and enforcement planning (see DMARC reports).
- Hosted DMARC and hosted BIMI on entry tiers
The Free plan includes Hosted DMARC and Hosted BIMI, which supports BIMI adoption and helps teams centralize record management and brand indicators without relying on manual handling for every update. - One-click DNS publishing and DNS change visibility
The platform includes one-click DNS publishing, plus DNS timeline and security score history features, which can reduce manual overhead when authentication records change often.
- Threat visibility features
The platform highlights a live threat map and “visibility powered by threat intelligence,” which is useful when you want to track spoofing attack patterns at a higher level.
- Hosted security add-ons and expansion path
The Basic plan includes Hosted MTA-STS, Hosted TLS-RPT, and TLS reports, while Hosted SPF is shown as an add-on on the pricing page. Enterprise expands to include Hosted DKIM as well.
If your team is trying to move from monitoring to DMARC enforcement across multiple sending sources, PowerDMARC is positioned as a single platform for SPF, DKIM, and DMARC visibility and reporting.
See how PowerDMARC helps you reach DMARC enforcement across multiple sender domains.
Pros
- Strong coverage of hosted services and reporting in one platform, including DMARC reports, TLS reporting, and add-on hosted SPF.
- The Partner Program supports multi-tenancy, white-labeling, API support, and PSA integration, which fits MSP-style delivery.
- Consistently high customer satisfaction on G2.
Cons
- Like most email authentication programs, time-to-enforcement still depends on cleaning up sending sources and fixing SPF/DKIM alignment before moving to strict DMARC policies.
- Basic plan domain and user limits can be a constraint for larger portfolios unless you size up.
Best for
Organizations that need automated solutions for email spoofing prevention at the domain level, especially when multiple business units, vendors, or subsidiaries send from the same parent brand. Also a fit for MSPs and MSSPs that need multi-tenant separation and delegated access.
Pricing
- Free: $0 for personal domains with limited reporting and 10-day data history.
- Basic: Starts at $8/month and $6.42/month if billed annually.
- Enterprise: Custom pricing for large organizations needing unlimited domains.
- Partner program: Custom plans for MSPs and MSSPs managing multiple client domains.
Rating
| Did you know? When you move from monitoring to a strict DMARC policy (quarantine or reject) and alignment is correctly configured, it becomes much harder for attackers to successfully spoof your sending domain. |
2. EasyDMARC
EasyDMARC is positioned as a centralized platform for managing email authentication across SPF, DKIM, and DMARC, with dashboards and plan-based features aimed at getting teams from reporting to enforcement. On its site, EasyDMARC frames the product around simplifying the “DMARC journey” for organizations that need better visibility into authentication failures that enable email spoofing, phishing emails, and business email compromise.
For teams that manage multiple sender domains and vendors, the practical value is speed. How fast you can see which sending source is failing alignment, spot unauthorized senders, and decide what changes are safe before tightening DMARC records. The pricing page also makes it clear that capacity is designed around email volume, domain count, and data history, which matters when your mail streams grow fast.
Key capabilities
- DMARC reporting and visibility features across tiers. The plan comparison lists aggregate reports (RUA), failure reports (RUF), weekly email reports, subdomain detection, and email vendor identification as part of the reporting layer.
- Alerting, investigation, and monitoring add-ons as you scale. The comparison table includes items like alert management, phishing URL check, email investigation, and IP source monitoring as part of the broader monitoring toolkit.
- Enforcement support and managed options in higher tiers. Premium lists EasySPF and alert management, while Enterprise includes managed services and a dedicated DMARC engineer, plus SSO, audit logs, and API access.
Pros
- Published pricing and plan limits make early budgeting easier than fully quote-based tools.
- Clear feature ladder from reporting (Plus) to deeper controls and managed support (Enterprise).
- Good fit for operational workflows when teams need dashboards, alerts, and SPF help in one place.
Cons
- Key security and enterprise controls are gated. SSO, audit logs, API, and dedicated engineer support are shown under Enterprise.
- Sizing can get tricky at scale. Plans are tied to email volume, domains, and data history, so large portfolios often need a careful scoping pass.
- Free tier is limited for serious programs. The Free overview shows low email volume and short data history, which is fine for evaluation but tight for ongoing enforcement work.
Best for
Security teams that want a centralized way to manage DMARC reports, identify misaligned senders, and operationalize email spoofing prevention tools across multiple domains. It is especially relevant when you need a structured, plan-based approach to move toward DMARC enforcement while keeping an eye on false positives and legitimate emails.
Pricing
A no-cost tier exists. The entry paid plan (Plus) starts at $35.99/month (billed annually). Premium starts at $71.99/month (billed annually). Enterprise pricing is custom.
Rating
3. Red Sift OnDMARC
Red Sift OnDMARC is built for teams that want to move faster from DMARC monitoring to enforcement without turning DNS management into a weekly fire drill. It leans into operational workflows, especially for environments where multiple sender domains, shared IP addresses, and frequent vendor changes can break SPF DKIM alignment and create gaps attackers exploit for email spoofing and phishing attempts.
A key differentiator in how Red Sift positions OnDMARC is “control from inside the platform.” Instead of repeatedly editing DNS records across registrars, it promotes in-app management for DMARC, SPF, and DKIM, which is useful when security teams are trying to reduce manual steps while still tightening DMARC enforcement.
Key capabilities
- Dynamic Services (in-app record management): Manage DMARC, SPF, DKIM, MTA-STS, TLS-RPT, and BIMI from within OnDMARC.
- Investigate tool: Validate changes instantly instead of waiting for the reporting delay after DNS updates.
- Dynamic SPF (SPF lookup limit support): Higher tiers include “Unlimited Dynamic SPF” to help beat the 10 DNS lookups limit that often stalls enforcement.
- Event Hub: Stream security and audit events via native SIEM integrations, webhooks, Slack, and more.
- DNS Guardian (Premier): Positioned for added protection coverage beyond standard DMARC.
Pros
- Strong workflow orientation for multi-domain DMARC operations, especially when DNS edits are a bottleneck.
- Includes an “instant verification” approach (Investigate) that supports faster troubleshooting and rollout.
- Review sentiment on G2 repeatedly highlights ease of use and support quality.
Cons
- The platform can feel information-dense at first, especially for teams new to domain based message authentication programs.
- Published list pricing is clear for Express, but higher tiers are quote-based, which can slow down side-by-side budgeting.
- Express has defined included limits (such as domain count and data history), so teams with larger portfolios may outgrow it quickly.
Best for
Organizations and service providers running DMARC across many sender domains who want faster operational workflows for policy progression, sender source validation, and SPF resilience, without relying on manual DMARC report triage alone.
Pricing
Express starts at $9/month (billed annually). Essentials, Enterprise, and Premier are quote-based.
Rating
4. Valimail
Valimail is typically shortlisted when organizations want a structured path from DMARC visibility to steady DMARC enforcement, especially in complex sender ecosystems. Its positioning is straightforward: start with Monitor for visibility into who is sending on your behalf, then move to Enforce for continuous protection against phishing and spoofing attacks.
This approach maps well to real-world spoofing prevention. Most domain-level abuse does not begin with a compromised inbox. It starts when attackers forge the sender address and your authentication program cannot confidently separate legitimate emails from unauthorized senders. Valimail’s product pages emphasize automation aimed at reaching enforcement faster, including features designed to reduce DNS-heavy manual work.
Key capabilities
- Monitor (free) for domain visibility: Identifies sending services “by name” and provides visibility and control into unauthorized email.
- Automated DMARC for continuous enforcement (Enforce): The plan comparison describes automated DMARC designed to get you to continuous enforcement without needing to touch DNS.
- Instant SPF and Unlimited SPF (Enforce): The pricing comparison highlights Instant SPF and “Unlimited SPF” to address SPF limits while avoiding disruption.
Pros
- Clear on-ramp with Monitor to quickly surface sender domains and unauthorized use before tightening policies.
- Enforcement tiers are framed around continuous protection and faster movement to DMARC enforcement.
- Strong volume of third-party user feedback on G2 for usability and reporting.
Cons
- Enforce is sales-led for most tiers, so detailed cost comparisons may require a pricing conversation.
- Subdomain management and reporting are positioned as starting at Premium, which can matter for large domain portfolios.
- Like any authentication program, enforcement outcomes still depend on correct sender cleanup and alignment work.
Best for
Large organizations that want to start with free DMARC visibility, then shift into a more enforcement-driven workflow to reduce spoofed emails, phishing attempts, and brand impersonation risk across many sending services.
Pricing
Monitor is the free tier. Enforce Starter starts at $5,000/year, while Premium and Enterprise are quote-based.
Rating
5. Proofpoint Email Fraud Defense
Proofpoint Email Fraud Defense is built for a specific problem: attackers who impersonate trusted brands by manipulating the sender address and domain signals, then using that deception to drive business email compromise and invoice fraud. It is less about “more email filtering” and more about restoring trust at the domain level by tightening email authentication and reducing brand impersonation exposure.
Proofpoint positions Email Fraud Defense as a guided DMARC program, combining workflow support with services, so teams can implement Domain-based Message Authentication, Reporting, and Conformance without breaking legitimate mail flow. That matters in enterprise environments where dozens of vendors and business apps send on behalf of the organization, and where the message body may look routine even when email headers reveal suspicious authentication status.
Key capabilities
- Guided DMARC rollout with support services: Proofpoint emphasizes guided workflows and support from consultants to streamline DMARC implementation and reduce disruption.
- Visibility into emails sent using your domains: The solution is positioned to show sources of email sent using your domains, helping teams identify legitimate senders versus unauthorized senders.
- Lookalike domain visibility: Proofpoint highlights visibility into lookalike domains and impersonation activity, which is a common driver for phishing emails and fraudulent emails.
- Supplier and third-party risk insights: Email Fraud Defense is also positioned to provide insight into fraud risks posed by suppliers, useful when vendor impersonation overlaps with invoice fraud and BEC.
Pros
- Strong fit when the goal is domain-level spoofing protection tied to DMARC, not just inbox-level detection.
- Lookalike domain and supplier risk coverage can help address brand impersonation patterns that bypass traditional “sender domains only” views.
- Consistent user feedback on G2 indicates solid overall experience for the product category.
Cons
- The public site does not provide list pricing, which makes quick cost comparisons harder without a sales conversation.
- Because it is services-assisted and program-oriented, rollout timelines and effort depend on how many sending sources and third-party systems need to be classified and aligned before enforcement.
Best for
Enterprises that are dealing with domain spoofing, supplier impersonation, or repeated BEC-style fraud attempts, and want a guided path to stronger DMARC enforcement plus visibility into lookalike domains that deceive recipients.
Pricing
Pricing is quote-based.
Rating
6. Mimecast DMARC Analyzer
Mimecast DMARC Analyzer is positioned around stopping direct domain spoofing by giving domain owners a clearer view of who is sending on their behalf and what is failing authentication. It is designed to help organizations get DMARC in place faster, improve visibility across email channels, and reduce brand misuse through spoofed emails.
Where it fits in this list is straightforward: if your spoofing problem is tied to domains, not compromised inboxes, DMARC Analyzer focuses on closing that gap through DMARC reporting, monitoring, and guided setup so mail servers can treat unauthorized senders more aggressively.
Key capabilities
- DMARC reporting plus real-time insights: Visibility into sending sources, IP addresses, and deliverability data, supported by forensic reporting.
- DMARC record setup wizard: A guided workflow to get from onboarding to monitoring quickly.
- Active monitoring service and enforcement support: The product page highlights the ability to instruct receiving platforms on how to treat messages and enforce DMARC policy outcomes.

7. Barracuda Email Protection
Barracuda Email Protection sits in a slightly different lane than DMARC-only platforms. It is an email security bundle that combines filtering and threat controls with domain fraud protection, including DMARC reporting and analysis. For teams dealing with spoofing attacks alongside phishing emails, malicious links, and business email compromise, that “bundle” approach is often the reason it gets shortlisted.
Where it connects to the intent of this blog is the domain abuse angle. Barracuda explicitly calls out preventing email domain fraud using DMARC reporting and analysis, with an emphasis on minimizing false positives, protecting legitimate email, and preventing spoofing.
Key capabilities
- DMARC reporting and analysis (domain fraud protection): Barracuda lists DMARC reporting as part of its Email Protection plans, positioned to help prevent spoofing and reduce false positives.
- Email threat protection built into the bundle: Protection against phishing, malware, and broader email threats is part of the core positioning for Email Protection.
- User-facing warning banners: The plans page highlights warning banners that explain why an email was flagged as suspicious, which can reduce “why was this blocked?” friction for users.
- Automated incident response (plan-dependent): Listed as part of the Email Protection plans, useful when security teams want faster handling of suspicious emails at scale.
Pros
- Covers both sides of the problem: domain fraud (DMARC reporting) plus broader email security protections in one platform.
- Explicit focus on minimizing false positives for legitimate email while still addressing spoofing risk.
- Solid review sentiment on ease of use and setup on G2.
Cons
- Because it is a bundle, scoping can take longer if you only need DMARC-centric capabilities versus full email security coverage.
- Review themes on G2 include occasional filtering issues and false positives that may need tuning depending on environment.
Best for
Organizations that want email spoofing prevention tools as part of a broader email security platform, especially when spoofed emails and phishing attempts overlap with malware delivery, malicious emails, and user-targeted deception.
Pricing
Pricing is sales-led.

8. Fortra DMARC Protection (Agari)
Fortra DMARC Protection (formerly Agari DMARC Protection) is positioned around one core job: automating Domain-based Message Authentication, Reporting, and Conformance so domain owners can reach stronger enforcement and reduce brand abuse tied to spoofed emails and phishing attacks. The product page explicitly frames it as DMARC automation that supports authentication and enforcement outcomes.
In environments where many third-party services send on your behalf, spoofing prevention usually breaks down at the “who is sending” layer. Fortra leans into that visibility problem by highlighting threat intelligence that identifies and monitors third-party senders, which is useful when sender domains, IP addresses, and authentication status are changing frequently.
Key capabilities
- DMARC automation and enforcement: Positioned to automate DMARC email authentication and enforcement and instruct receiving mailboxes how to treat messages that fail DMARC.
- Ongoing monitoring after enforcement: The product page stresses that monitoring remains important even after you reach a reject policy, as attacker tactics evolve.
- Threat intelligence for third-party sender discovery: The solution brief highlights identifying, monitoring, and managing email being sent on your behalf by third-party senders.
- Hosted DNS record support (capability notes): Fortra documentation notes hosting DNS records relating to DMARC, SPF, and DKIM, including DKIM record management capabilities.
Pros
- Strong alignment with the blog intent: domain-level automation aimed at reducing spoofing and phishing risk tied to brand abuse.
- Clear positioning around decreasing “time to reject” by automating implementation, which matters when security teams want enforcement without prolonged manual cycles.
Cons
- Pricing is not public, so comparing cost alongside fixed-price or published-tier tools requires a quote request.
- G2 has limited review volume for this specific listing, so peer sentiment is thinner than for more widely reviewed DMARC vendors.
Best for
Enterprises that want a DMARC-centered approach to brand abuse reduction, especially where many third-party senders and systems send email on behalf of the organization and the goal is faster movement toward enforcement.
Pricing
Pricing is quote-based.

9. Microsoft Defender for Office 365
Microsoft Defender for Office 365 is a native Microsoft 365 layer focused on protecting users from email threats such as phishing attempts, business email compromise, malicious links, and malware in attachments. It is not a dedicated DMARC platform, but it often shows up in shortlists because many security teams want a built-in option for advanced protection and automation within the Microsoft ecosystem.
For spoofing prevention, the key point is scope: Defender helps reduce the impact of spoofed emails by detecting suspicious emails and blocking threat delivery mechanisms (links, attachments, impersonation patterns). DMARC enforcement, DMARC records management, and DMARC reports are typically handled through separate domain authentication tooling and DNS workflows.
Key capabilities
- Safe Links to protect against phishing and other attacks that use malicious URLs across email and collaboration tools.
- Safe Attachments to detonate and analyze attachments before delivery to help stop malware and malicious emails.
- Plan 2 investigation and response features positioned for SOC teams that need more visibility and remediation capabilities.
- Anti-phishing protections designed to detect impersonation and related email attacks (Microsoft documentation positions this under Defender for Office 365 capabilities).
Pros
- Strong fit for Microsoft 365 environments because it is deeply integrated into the same admin and security stack.
- Helps reduce user exposure to clicking malicious links and downloading malware, which often accompany spoofing and BEC campaigns.
- Widely reviewed on G2 with strong overall sentiment for core email protection features.
Cons
- Does not replace DMARC-centric tools for domain based message authentication visibility, DMARC reports analysis, and enforcement workflow management.
- Full capabilities vary by licensing tier and plan, which can complicate budgeting across mixed user groups.
Best for
Organizations already standardized on Microsoft 365 that want built-in email security automation to reduce phishing emails, malicious links, and suspicious emails, while handling DMARC implementation and enforcement separately through dedicated domain authentication processes.
Pricing
Pricing plans start from $12/user/month.

10. DMARC Report
DMARC Report (by DuoCircle) is built for teams that want DMARC reporting to feel operational, not academic. Instead of living in raw XML, you get a platform designed to help domain owners and service providers monitor how sender domains are being used, identify unauthorized senders, and move toward DMARC enforcement with fewer blind spots.
It is often evaluated when organizations need to manage multiple domains at once, especially in MSP-style environments where reporting clarity, segmentation, and client-ready outputs matter as much as the underlying email authentication protocols.
Key capabilities
- Aggregate and forensic reports: DMARC Report lists both aggregate and forensic reporting as core features for identifying passing and failing authentication outcomes.
- White-label reporting: Brand the interface and reporting URL for client-facing use cases.
- MTA-STS and more email security add-ons: The platform lists features such as MTA-STS (and other supporting capabilities) as part of its feature set aimed at stronger authentication and secure delivery.
Pros
- Strong clarity for “who is sending on your behalf,” which helps teams isolate misaligned sender domains and spot potential spoofing attempts faster.
- Built with multi-domain scale and collaboration in mind, including role-based access and workflows highlighted in the product overview.
- Very high review volume for this category on G2, which makes peer sentiment easier to trust than listings with only a handful of reviews.
Cons

Which Tool Should You Choose?
Most buyers get this wrong by comparing feature lists. The better approach is to match tools to the exact problem you are solving.
If your top priority is stopping spoofed emails that use your domain name
Pick a DMARC-first platform that helps you identify sending sources, fix SPF and DKIM alignment, and progress toward DMARC enforcement without triggering false positives.
Shortlist: PowerDMARC, Valimail, Red Sift OnDMARC, EasyDMARC.
If your domain portfolio is large, messy, or shared across subsidiaries and vendors
You need portfolio-level visibility across sender domains, shared IP addresses, and DMARC reports, plus controls for delegation and multi-domain management.
Shortlist: PowerDMARC, EasyDMARC, Red Sift OnDMARC, DMARC Report.
If you are dealing with look alike domains and brand impersonation outside your mail system
You need coverage beyond standard DMARC reports, because the abuse may not be coming from your sending domain at all.
Shortlist: Proofpoint Email Fraud Defense.
If your biggest risk is user-targeted phishing and malware delivery inside Microsoft 365
You want inbox-layer automation that blocks malicious links, suspicious emails, and payloads, but you will still need a DMARC platform if you want strict domain enforcement.
Shortlist: Microsoft Defender for Office 365.
If you want email security plus DMARC reporting in one bundled platform
Choose this when you want filtering and threat protection alongside domain fraud reporting.
Shortlist: Barracuda Email Protection.
If you mainly need structured reporting outputs at scale
Choose a reporting-oriented platform when reporting, exports, and multi-domain oversight matter more than enforcement automation depth.
Shortlist: DMARC Report.
If you want one platform that covers the domain-authentication layer end to end across a portfolio, PowerDMARC is usually the best fit. It is built for centralized visibility and standardized SPF, DKIM, and DMARC management across many sending sources.

FAQs: Automated solutions for email spoofing prevention
1) What is the fastest way to stop email spoofing?
The fastest sustainable path is to implement SPF, DKIM, and DMARC correctly, then move toward DMARC enforcement. Inbox-layer tools can reduce harm from suspicious emails, but DMARC enforcement is what helps mail servers reject spoofed emails that use your sending domain.
2) Does SPF alone prevent spoofed emails?
No. Sender Policy Framework (SPF) helps validate authorized IP addresses, but attackers can still spoof the sender address, and SPF can fail due to forwarding or misalignment. You typically need spf dkim and dmarc working together for reliable email authentication and brand protection.
3) What is the difference between email spoofing and phishing?
Email spoofing is the technique of forging the sender domain or sender address. Phishing is the goal: trick users into clicking malicious links, sharing credentials, or downloading malware. Many phishing attacks start with spoofed emails because they appear to come from trusted brands.
4) Why do organizations stay stuck at DMARC p=none?
Most get stuck due to:
- Unknown or unmanaged sending sources.
- SPF lookup limit problems and SPF breakage.
- DKIM misalignment across vendors.
- Fear of blocking legitimate emails and creating false positives.
Automated solutions help by processing DMARC reports, revealing unauthorized senders, and supporting safer DMARC enforcement steps.
5) Can Microsoft Defender for Office 365 replace a DMARC tool?
Not typically. Microsoft Defender helps block malicious emails, phishing attempts, and suspicious emails inside Microsoft 365. But it does not replace DMARC records management, DMARC reports analysis, or domain-level DMARC enforcement workflows. Many security teams use both: Defender for inbox protection, plus a DMARC tool for domain based message authentication.
6) How do automated solutions reduce false positives?
They reduce false positives by showing authentication status per sender domain and IP address, helping you separate misconfiguration from abuse. Better platforms also support staged enforcement, so you can tighten policy without breaking legitimate emails.
