What you actually get

Built for the boring middle of DMARC.

Going from p=none to p=rejecttakes most teams 4–12 weeks. We make the middle observable, reversible, and fast.

Policy Simulator

See the blast radius before you enforce.

Replay the last 30 days against any policy. Which senders break under p=reject? Which ESPs need a DKIM key first? Answer before you touch DNS.

ARC Chain Monitoring

Track authentication across forwarders — mailing lists, alumni redirects, calendar forwarders — without false rejects.
