Semperis builds AI-powered identity security and cyber resilience software that protects enterprise identity systems against ransomware, data breaches and operational errors. Its remit covers hybrid identity estates: on-premises Active Directory, Entra ID and Okta. The field is a large one - around 90% of organisations run Active Directory as their core identity system, and the company reports that nine out of ten cyberattacks target it.
Its main product, the Identity Resilience Platform, is positioned as a last line of defence across those environments and is claimed to cut recovery time after an attack by 90%. Semperis states that its technology protects more than 100 million identities. Alongside the commercial platform, the company distributes two free community tools: Purple Knight, for identity and Active Directory assessment, and Forest Druid, for attack-path analysis. Both are used by thousands of security professionals worldwide.
Technical work spans identity security, Active Directory security, AI-powered security, directory services protection, ransomware recovery and hybrid identity protection. Semperis operates globally, is a Microsoft Enterprise Cloud Alliance partner and a member of the Microsoft Intelligent Security Association, and has been recognised in the United States as one of the country's fastest-growing companies and best workplaces.
The company describes its mission as "building a movement to be a force for good in cybersecurity". Beyond product development it runs the award-winning Hybrid Identity Protection (HIP) conference and podcast series.
