Defend against spoofing with DMARC email security.

The DMARC email security protocol has become a critical weapon in the fight against email spoofing and impersonation. But what is DMARC, exactly, and what are its benefits and limitations in preventing these sophisticated attacks?

DMARC stands for Domain-based Message Authentication, Reporting and Conformance, a protocol for authenticating that an email received from a specific domain is legitimately using that domain and is not fraudulent.

Sending a fraudulent email from a legitimate domain is one of the techniques used by cyber criminals to trick users into divulging sensitive information or wiring money to fraudulent accounts. DMARC email security protocols can help to prevent this specific type of attack by allowing senders to notify recipients that their messages are protected by SPF and/or DKIM authentication and providing instructions for what to do if an email passes neither one of those authentication methods. Essentially, DMARC email security takes the guesswork out of the way that receivers handle failed messages, minimizing the recipient's exposure to potentially fraudulent email and helping to protect the sender's domain from being used fraudulently.

While DMARC email security can be highly effective at stopping a particular kind of attack, cyber criminals are very adept at finding many ways of breaching an organization's security. That's why so many companies turn to Mimecast for solutions that combine DMARC email security with other highly effective and multilayered defenses.
