Email: fake by default

Email’s identity crisis

Email was invented alongside the internet, and both have grown to become the core of today’s online world. Unfortunately, email’s evolution has been slowed by a lack of built-in identity. By default, anyone can send email pretending to be someone else, leading to email’s identity crisis:

90%+ of all cyber attacks involve fake email.

When email domains can be hijacked to send malicious email, reputations suffer, people lose trust, and fraud is allowed to spread. DMARC solves email’s identity crisis by giving Internet domain owners control over how their domains can be used in email. dmarcian’s mission to help people everywhere adopt DMARC.

Robbie Ward Senior Infrastructure Engineer | Dublin City University

dmarcian made DMARC very simple to set up with examples and reporting that allowed me to monitor at first and work our way up to a 100% p=reject DMARC policy. The tools were easy to use and helped me build the SPF, DKIM and DMARC records to publish on our DNS.
