Maximizing Email Security through DMARC Report Analysis

Email is an essential communication tool in both personal and professional settings. As such, it has become a prime target for hackers and malicious actors who aim to compromise user email accounts, steal sensitive information, infiltrate organizations, and launch spam attacks. To address these security concerns, DMARC (Domain-based Message Authentication, Reporting & Conformance) has emerged as a crucial email authentication protocol that helps prevent email fraud and phishing attacks. In this article, we will discuss how organizations can analyze DMARC reports to identify security gaps and improve email security.

Why DMARC is Important?

DMARC is a protocol that builds on top of existing email authentication protocols such as SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to provide a way for email receivers to determine if incoming messages are authentic or not. DMARC helps to prevent domain spoofing, a common tactic used by cybercriminals to make fraudulent emails look as if they were sent from a legitimate email address, and to instruct email receivers on how to handle unauthenticated emails. Without DMARC, attackers can send spoofed emails with malicious links, impersonating legitimate senders and infecting receivers with malware.

How DMARC Works?

DMARC works by using an email sender’s published DMARC policy to instruct email receivers on how to handle unauthenticated messages. If a DMARC policy is not published for a domain, then the email receiver will not know how to handle messages that fail authentication checks. DMARC combines the results of SPF and DKIM checks to assess the authenticity of a message with a specific “from” domain and determines whether to deliver, quarantine, or reject the message based on the DMARC policy published by the domain owner.

What are DMARC Reports?

DMARC reports are messages that email receivers send back to the domain owner about the results of their DMARC checks. These reports provide insight into how email is flowing from a domain, which helps the domain owner to evaluate if the DMARC policy is effective and identify potential issues or threats. DMARC reports typically include information such as the number of messages received, how many passed compliance checks, and how many failed.

How to Analyze DMARC Reports?

Analyzing DMARC reports can help organizations to evaluate their email security posture and identify areas for improvement. Here are some best practices for analyzing DMARC reports:

1. Determine the Source of Unauthenticated Emails

DMARC reports provide information on emails that failed authentication checks. This information can help organizations to identify the source of unauthenticated emails, including who is sending them and from where. Organizations can then take corrective actions such as blocking these emails or contacting the senders to address the issue.

2. Identify Spoofed Emails

DMARC reports can help organizations to identify spoofed emails that are sent from a domain that is masquerading as a legitimate sender. By analyzing the headers and information in these emails, organizations can determine if they are originating from a reliable source or if they are a potential phishing attempt.

3. Evaluate DMARC Compliance

DMARC reports can provide information on how well an organization’s DMARC policy is being enforced and whether email receivers are following their DMARC instructions. This information can help organizations to identify and fix authentication gaps.

4. Track Email Delivery and Security Trends

DMARC reports can give insight into email delivery and security trends over time. Analytics such as volume and trend metrics can help an organization to review the effectiveness of its email security measures and identify potential areas for improvement.


In conclusion, analyzing DMARC reports can help organizations to evaluate their email security performance and take steps to improve it. By identifying the source of unauthenticated emails, spotting spoofed emails, evaluating DMARC compliance, and tracking email delivery trends, organizations can enhance their email security posture and reduce the risk of targeted attacks. As such, we highly recommend that organizations implement DMARC reporting in conjunction with standard email security measures to further protect their email infrastructure.
