Exposure management, compared

Discovery is no longer the hard part. The tools worth paying for are the ones that prove what an attacker could actually exploit, and get it fixed. These guides compare the leading platforms across three related categories, scored on published capability. They are written to be useful whether or not Patrowl ends up on your shortlist.

How they fit together

The three categories are not competitors: they are layers of the same job. CTEM is the continuous program that ties everything together. EASM is the discovery layer that feeds it. Automated penetration testing is the validation layer that proves which exposures are real. Start with whichever matches the decision in front of you.
