Swiss DMARC platform · since 2026
Who's spoofing your domain?
Deemarc pulls the DMARC aggregate reports straight from your Microsoft 365 tenants, surfaces spoofing attempts and tells you exactly which of your sending sources still aren't authenticated cleanly.
The problem
You see the attack
only when a customer calls.
DMARC reports land in random mailboxes, as XML, compressed, hourly, from dozens of reporters. Without tooling they're unreadable. With tooling they're a precise early-warning system.
