How Monitor works

The risk-free visibility you need to prevent phishing attacks and rein in shadow IT.

Unmatched discovery of third-party sending services

Monitor instantly identifies thousands of sending services, making it easy to distinguish legitimate senders from bad actors, saving you the trouble of wading through IP addresses one by one.

Continuously monitor your enforcement status

Instantly find areas of vulnerability with detailed views into the enforcement status of all sending domains, including which domains are passing and failing DMARC, aligned SPF and DKIM, and overall disposition.

Global view of suspicious IPs sending as you

Gain direct access to view unidentified ISPs, open routers, unsecured hacked servers, and more to keep you in control of your domains.
