Tunisia DMARC & MTA-STS Adoption Report 2025

According to the Global Organized Crime Index, cyber-attacks in Tunisia are increasing significantly. The cyber-attacks mainly target the industrial sector and lead to approximately millions of Tunisian dinars of losses a year. The Tunisian financial industry, on the other hand, enjoys a higher degree of protection from cyber-attacks compared to the government. As a result, Tunisia is now experiencing a significant increase in demand for local cybersecurity solutions. Studies predict that the cybersecurity market in Tunisia will possibly see a significant growth in revenue, reaching up to US$42.50m in 2025.

In this report, we will analyze Tunisia’s current cybersecurity posture. We will focus on studying the adoption levels of key email authentication protocols like  DMARC, SPF, MTA-STS, and DNSSEC. Additionally, we will provide useful and actionable recommendations to help Tunisia improve its current security posture. 

Assessing the Threat Landscape

PowerDMARC’s Tunisia DMARC and MTA-STS Adoption Report 2025 will focus on the following important issues:

  • To what extent does MTA-STS vary from one sector to another in Tunisia?

  • Which sectors in Tunisia enable DNSSEC?

  • What measures can the Tunisian government take to enhance its digital security posture?

  • Are some sectors more likely to become victims of cyber attacks than others?

DMARC & MTA-STS Adoption Rates: Key Statistics for Tunisia 

  • 76.44% of Tunisian domains have correctly implemented SPF records. 21.26% do not have SPF records.

  • DMARC adoption is lower. Only 30.08% of domains have correct DMARC records. A substantial 69.92% of Tunisian domains still lack DMARC implementation.

  • Among domains with DMARC, the policy distribution is skewed towards less protective measures:

    • 13.98% have a policy set to “none,” providing minimal protection.
    • Only 4.79% have a “reject” policy, which offers maximum protection against email-based attacks.
    • 11.30% use a “quarantine” policy, ensuring intermediate protection.
  • MTA-STS adoption is non-existent in Tunisia. 100% of Tunisian domains lack this important layer of email security.

  • DNSSEC implementation is very limited. Only 5.94% of domains have it enabled, while a vast majority of 94.06% have it disabled.

Critical Errors Organizations in Tunisia Are Making

  • SPF-Related Errors

    While the SPF adoption rates are rather high in Tunisia, there are many errors that organizations in Tunisia make. These include:

    • SPF records that do not comply with the 10 DNS lookup limit
    • SPF records that exceed the SPF void limit of 2
    • Errors related to the DNS record syntax and configuration.
  • DMARC Implementation Drawbacks

    Many domains in Tunisia use highly permissive DMARC policies such as “none.”  “reject” policy implementation, on the other hand, is quite low. The “none” policy provides no protection and makes these domains vulnerable to cyber threats. 

    Syntax and configuration errors are also common factors affecting proper DMARC implementation for most domains.

  • Lack of MITM Attack Protection

    MTA-STS adoption is non-existent across all sectors in Tunisia. All domains lack this important security measure. This means that there is no adequate TLS encryption for inbound email delivery to a domain, which leaves communications vulnerable to Man-in-the-middle attacks. 

  • Lack of DNS Attack Protection

    DNSSEC adoption rates are generally low but vary among sectors, indicating a lack of security against DNS attacks.

How Can Organizations in Tunisia Improve Email Security & Deliverability?

Organizations in Tunisia can improve email security & deliverability by: 

  • Increasing SPF adoption, particularly in the government sector where it’s the lowest.

  • Using stricter DMARC policies (like “quarantine” or “reject”) across all sectors.

  • Going beyond just DMARC to implement BIMI and MTA-STS across all sectors to enhance email transport security.

  • Enabling TLS-RPT to support MTA-STS implementation, and monitor deliverability reports. 

  • Improving DNSSEC adoption among all sectors

  • Ensuring SPF and DMARC records do not contain syntactical or configuration errors by using managed email authentication services and automated solutions.

  • Enabling DMARC reporting to monitor email deliverability regularly, and troubleshoot errors as and when they arise. 

  • Following email authentication best practices or relying on a managed DMARC solution with a team of experts to handle email authentication on their behalf.

PowerDMARC provides a wide range of email authentication SaaS services, combining DMARC, SPF, DKIM, BIMI, MTA-STS, and TLS-RPT hosted.
