Expert guidance to protect hybrid AD before, during, and after an attack

When organizations experience a cyberattack, identity systems are often the primary target—especially Active Directory (AD) and Entra ID, used by over 90% of enterprises worldwide. Attackers commonly go after highly privileged identities and embed backdoors to maintain access. Historically, recovery required a full AD rebuild—a costly, months-long effort with serious operational impact. An AD compromise can cause weeks of downtime, even for organizations that pay the ransom.

Semperis Identity Forensics & Incident Response (IFIR) addresses the entire lifecycle of an identity-layer attack. Our specialized team provides rapid containment, forensic investigation, and secure recovery to minimize downtime and prevent reinfection.

Semperis was able to backup and restore AD insanely quickly. During our testing, we were able to back up and restore our Active Directory within 20 minutes to a completely different datacenter with minimal downtime. During a normal backup scenario, that could take 24-36 hours.

With ADFR, I knew I wouldn’t have to go through hours and hours of clicking through procedures and potentially reintroducing malware. Being able to leverage ADFR in the first three hours of the incident response saved me probably two to three weeks.
