Semperis

Identity resilience platform defending and recovering Active Directory, Entra ID, and Okta.

Semperis protects the identity systems attackers go after first. It hardens and monitors Active Directory, Entra ID, and Okta, detects attacks in progress, and can rebuild Active Directory cleanly after a compromise. Founded in 2013, it serves enterprises where the directory is a single point of failure.
