What is DMARC?

All businesses should be familiar with the DMARC standard and its role in helping to secure email from threats like spam, phishing and most critially to protecting your brand - email spoofing! But What is DMARC exactly, and how does it add another layer of security to business email systems?

DMARC is Domain-based Message Authentication, Reporting and Conformance, a technical standard that helps protect email senders and recipients from advanced threats. DMARC provides a way for domain owners to outline their authentication practices and specify the actions to be taken when an email fails authentication. DMARC also provides a way for recipients to report on email that fails authentication.

DMARC benefits businesses by providing another layer of protection that guards against attacks like impersonation fraud, where an attacker uses a legitimate domain to send a fraudulent message.

DMARC compared to SPF and DKIM

Sender Policy Framework, or SPF, is an email validation protocol used to verify the legitimacy of a sender's domain by defining which IP addresses are allowed to send email from a specific domain. DMARC is an authentication protocol that builds on the SPF standard and enables domain owners to specify how email should be handled when it fails authentication.

DomainKeys Identified Mail (DKIM) is another authentication protocol that allows a sender to digitally sign an email with the organisation's domain name, ensuring the message's authenticity. As with SPF, DMARC builds on the DKIM standard by enabling senders to say how messages that fail authentication should be treated.
