Hard Lessons from Real-World Identity Disasters
Attacks on identity infrastructure have evolved from targeting individual accounts to compromising entire identity systems—often starting on-premises and propagating to cloud environments.
Alex Weinert, Chief Product Officer at Semperis and former VP of Identity Security at Microsoft, outlines a three-part framework for protecting identity fabric: before attacks (posture work), during attacks (detection and response), and after attacks (secure recovery). Through the lens of five detailed case studies of real-world identity security incidents from Semperis’ response team, he illustrates critical lessons including the importance of proper preparation and rehearsal, the need for immutable backups, the value of identity forensics, challenges with communications during incidents, and the importance of documenting response actions for regulatory compliance.
