Report Estimates BEC Costs Avoided By DMARC
A report released by the Global Cyber Alliance in late October attempts to quantify the expenses avoided by the companies that they have helped to implement strict DMARC policies (quarantine or reject).

Zendesk moves to “p=reject”
Customer service and support platform provider Zendesk has employed DMARC to monitor email activity using their domains for several years. In September, Zendesk switched over 80,000 sub-domains that they use to support their customers to a “p=reject” DMARC policy. This prevents fraudulent email using these sub-domains from reaching consumers, and protects their customers’ and Zendesk’s […]
