See external assets you didn't know you had

Informer’s external asset discovery engine uses a vast range of open-source intelligence (OSINT) techniques and a wide range of data sources to locate known and unknown assets you didn’t know you had. The internet is monitored for new assets and changes to assets to keep you fully up-to-date on your external attack surface.
