About Semperis
Semperis is an identity-driven cyber resilience and crisis management company that protects critical identity systems from agentic and conventional cyberattacks. Semperis is a private company and B2B cybersecurity provider specializing in Identity Threat Detection and Response (ITDR), cyber crisis management, and hybrid identity protection solutions and services. Semperis focuses on comprehensive identity resilience across the full attack lifecycle of prevention, detection, response, and recovery. Semperis states that its proprietary AI-powered technology is purpose-built for securing hybrid identity environments, including Active Directory, Entra ID, and Okta. Semperis helps organizations prevent, detect, respond to, and recover from agentic and conventional identity attacks.[1][3]
Semperis states that every user, workload, and agent depends on identity providers like Active Directory, Entra ID, and Okta. Semperis states that Active Directory remains the identity source of truth in most organizations. Semperis states that attackers commonly go after highly privileged identities and embed backdoors to maintain access. Semperis states that misconfigurations and unpatched vulnerabilities pile up over years, while attackers pivot between on-prem and cloud identity systems in search of elevated privileges. Semperis states that recovery historically required a full AD rebuild, a costly, months-long effort with serious operational impact.[3][5][6]
Directory Services Protector (DSP) is a Semperis product for hybrid identity threat prevention, detection, and response. Semperis delivers identity threat detection and response that combines tamperproof tracking of every directory change with automatic rollback of malicious activity. Directory Services Protector provides a single view of security vulnerabilities across the hybrid AD and Entra ID environment, including non-human identities, or service accounts. DSP includes hundreds of built-in, constantly updated security indicators to monitor hybrid AD and Entra ID environments for legacy vulnerabilities and emerging threats. DSP includes automated rollback to undo unwanted or malicious changes in both AD and Entra ID. DSP can identify service accounts, build an inventory, and monitor them with specialized indicators developed by the Semperis threat research team. Semperis offers attack detection powered by AI models developed by identity security experts to detect password spray, credential stuffing, other brute force attacks, and risky anomalies. Semperis offers out-of-the-box integrations for Splunk and Microsoft Sentinel that forward AD and Entra ID change data, DSP security indicator results, and notification rule events.[5][6]
Semperis describes Active Directory Forest Recovery (ADFR) as an automated AD disaster recovery approach. Semperis ADFR is a backup and recovery solution purpose-built for recovering Active Directory from cyber disasters. Disaster Recovery for Entra Tenant (DRET) provides backup and recovery for Entra ID. Delegation Manager for AD is a Semperis offering for secure AD permissions delegation. Migrator for AD is a Semperis offering for security-first AD migration and consolidation. Ready1 is an enterprise cyber crisis readiness and crisis management platform.[1][7]
Semperis Identity Forensics & Incident Response (IFIR) addresses the entire lifecycle of an identity-layer attack. Semperis states that its specialized team provides rapid containment, forensic investigation, and secure recovery. Semperis offers identity forensics following an attack to assess the damage, eradicate threat actors, and recover to a trusted environment. Semperis offers a service that gives a clear picture of AD security posture and a roadmap to address exposures at the strategic, operational, and tactical levels. Semperis offers a service to align recovery time objective (RTO) and recovery point objective (RPO) metrics and identify implicit dependencies that might hinder recovery plan execution. Semperis offers a review of identity and access management configuration from Entra ID security experts. Semperis offers expert guidance and purpose-built technology for AD migration and consolidation.[1][5]
Semperis offers free community tools: Purple Knight for identity security assessment and Forest Druid for Tier 0 attack path discovery. Semperis publishes original research into emerging threats, threat mitigation, and industry trends.[1]
Semperis was founded by Mickey Bresman (CEO), Guy Teverovsky (CTO), and Matan Liberman (EVP Business Development). Semperis has its headquarters in Hoboken, New Jersey, and operates internationally. Semperis raised a $40M Series B led by Insight Partners, bringing total funding at that point to $54M. Semperis raised over $200M in a Series C led by KKR, with Ten Eleven Ventures, Paladin Capital Group, Atrium Health Strategic Fund, Tech Pioneers Fund, and Insight Partners. Semperis secured $125M in growth financing to accelerate R&D and global expansion and bolster executive leadership. General David Petraeus (U.S. Army, Ret.), a Partner at KKR and former Director of the CIA, joined Semperis as a strategic advisor to help bolster identity threat detection and response in the public sector. Prime Healthcare needed to modernize and accelerate AD forest recovery after an internal change caused outages across multiple domain controllers. Temple Health, a healthcare system, sought an ITDR approach that met healthcare security and compliance requirements while simplifying recovery. Foulston Siefkin LLP moved to a hybrid AD and Entra ID environment and reviewed business continuity.[1][3][5][7][8]
