Unlocking the Foundations of Email Security

Understanding the role of SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) can seem daunting, but it’s essential for safeguarding your business communications. These three standards work together to verify the sender’s identity, ensuring that the emails your organization sends and receives are legitimate and secure.

In fact, a 2019 global adoption study showed 80% of organizations lacked DMARC setups, pointing out a big gap in email security.

  • SPF allows email senders to define which IP addresses are allowed to send mail for a particular domain.
  • DKIM provides a way to validate a domain name identity associated with a message through cryptographic authentication.
  • DMARC ties SPF and DKIM together with a consistent set of policies. It also provides reporting to senders, letting them know who is sending email on their behalf.

Not properly setting up SPF, DKIM, and DMARC records significantly increases vulnerability to cyberattacks. Malicious emails that spoof legitimate domains or originate from compromised accounts are becoming more frequent, partly because advanced security measures elsewhere have pushed criminals toward email-based attacks. Additionally, the accessibility of AI allows for more sophisticated and scaled email threats. Despite the availability of these protective protocols, their complex setup process has led to widespread under-utilization, leaving many organizations exposed to the risk of serious security breaches and reputational damage.
