80% of federal agencies now use DMARC

80% of federal agencies now use DMARC to protect the public from fraudulent emails sent in their names, Valimail reported on Friday. All agencies, save for defense and intelligence ones, were required by Homeland Security to implement DMARC by October of last year.

Why it matters: 80% is actually a pretty substantial improvement from Valimail’s last public statistic — when the deadline passed, only 57% of agencies met the DMARC requirement.
