DMARC: Fortune 500 Companies Don’t Use Basic Email Safety Protocol

August 28, 2017

By: Sikur



Nearly every company in the Fortune 500 is vulnerable to phishing attacks because they fail to utilize one of the most basic email security features available, according to a recently published report.

Cybersecurity firm Agari found more than nine out of 10 companies were not making use of a domain-based message, authentication, reporting and conformance (DMARC) protocol that would combat phishing attacks that use spoofed email addresses.

DMARC is an authentication standard that will reject messages that come from an unrecognized or unauthorized source. This is a relatively common phishing tactic, in which an attacker will use a spoofed domain to make it appear as though an email is coming from a trusted source.
