Strengthen Your Email Security with Giant: Your Expert Partner in DMARC Policy Enforcement

Email security is paramount in an era of increasingly sophisticated cyber threats. Recent advisories from the FBI, Department of State, and NSA highlight the urgent need for organizations to enforce robust DMARC (Domain-based Message Authentication, Reporting & Conformance) policies. These recommendations emphasize the critical vulnerabilities posed by weak DMARC settings, particularly the p=none policy. At Giant, we are poised to guide your business in navigating these new security mandates and fortifying your email defenses.

Understanding the DMARC Landscape

DMARC is an email validation system designed to protect your domain from being used in phishing and email spoofing attacks. The p=none policy, often used in the initial monitoring phase of DMARC deployment, does not actively prevent unauthorized use of your domain. This leaves a significant gap in your security that cyber attackers, such as the North Korean Kimsuky group, can exploit to conduct spear-phishing campaigns.

Why p=none Isn’t Enough

Many organizations, particularly small and medium-sized enterprises (SMEs), implement the p=none policy to satisfy regulatory requirements but fail to advance beyond this stage. However, maintaining a p=none policy is akin to leaving your front door unlocked—it provides no real protection against malicious activities. As the recent federal advisory points out, stricter policies such as p=quarantine and p=reject are necessary to combat these threats effectively.

Enforcing Stronger DMARC Policies

The advisory recommends two stronger DMARC policies:

  • p=quarantine: Emails failing DMARC checks are treated as spam and quarantined.
  • p=reject: Emails failing DMARC checks are outright blocked from delivery.

Implementing these policies ensures that unauthorized emails claiming to be from your domain are significantly less likely to reach their intended targets. This protects your brand’s reputation and secures sensitive information from being compromised.

Common DMARC Mistakes and How to Avoid Them

Advancing your DMARC policy can be challenging due to the complexity of domain catalogs and a lack of domain management expertise. Common pitfalls include an incomplete understanding of email sources and failure to configure DMARC reporting fields properly.
