The U.S. Department of Homeland Security issued a binding operational directive (BOD) requiring all federal agencies that use.gov email and website domains to secure email and deploy authentication technologies in the coming months.

Two-thirds of Fortune 500 companies, meanwhile, have not deployed any level of DMARC, according to an analysis of DNS records by Agari. Industry experts say the protocol’s low adoption rate may be blamed on a lack of education by users.”]
