The Identity Map / ITDR

ITDR: Identity Threat Detection & Resilience

Detecting and responding to identity-based attacks; Active Directory and Entra security, backup, and recovery.

Once attackers have a valid credential they stop hacking and start logging in, which is why identity is now the primary battleground. ITDR watches the identity fabric itself, Active Directory and Entra, SaaS sessions, and privileged behavior, to catch and contain attacks the perimeter never sees. It also covers the resilience half of the problem: backing up and rapidly recovering a compromised directory.
