Identity Threat Detection & Response

Hoboken NJ Active Directory security platform; raised $200M+; identity threat detection and response for AD, Entra ID, and hybrid identity environments.

About

Semperis is an identity security company founded in 2014 and headquartered in Hoboken, New Jersey. The company focuses on securing and recovering Active Directory (AD) and Azure Active Directory (Entra ID) environments, which represent the most critical identity infrastructure in the majority of enterprises. Active Directory is the primary authentication and authorization backbone for Windows environments globally, and it has become one of the most attacked components in modern ransomware and nation-state intrusions — attackers that compromise AD can gain access to every system in an organization.\n\nSemperis raised $200 million in a Series C round led by JP Morgan Growth Equity Partners and Vision Blue, valuing the company at approximately $1 billion. Its platform covers three domains: Directory Services Protector (DSP) for continuous AD threat monitoring and automated attack rollback; AD Security Assessment for evaluating the attack surface of AD configurations; and Active Directory Forest Recovery (ADFR) for rapid recovery of AD from cyberattacks. The ADFR product addresses a critical gap: most organizations' backup and recovery processes are not designed to recover AD cleanly from a ransomware attack that corrupted or encrypted AD data.\n\nSemperis's Purple Knight tool, a free Active Directory security assessment, has been downloaded by more than 10,000 organizations and is widely used by IT and security teams to benchmark their AD attack surface. The company's deep expertise in AD-based attack techniques — including DCSync, Golden Ticket, Kerberoasting, and pass-the-hash attacks — informs its detection engine, which monitors AD events in real time and can automatically roll back unauthorized changes before they cause damage.
