Sharelock is an Italian cybersecurity company headquartered in Rome, founded in 2017 by alumni of CrossIdeas, an identity governance startup acquired by IBM in 2014. The company develops an AI-driven identity security platform that combines Identity Security Posture Management (ISPM) and Identity Threat Detection and Response (ITDR) in a single unified solution. The platform consists of three core modules: Identity Security Posture, which provides proactive monitoring and hygiene enforcement across identity infrastructure; Identity Threat Detection, which delivers real-time detection of identity-based threats; and SIA (Security Investigation Autopilot), an agentic AI module that automates security incident investigation, developed in part through Italy's PNRR (National Recovery and Resilience Plan) funding. Sharelock's platform addresses use cases including privileged account misuse, lateral movement detection, insider threat identification, account profiling, risk-based access reviews, and least privilege and MFA enforcement. The solution is designed to cover both human and machine identities across on-premises and cloud environments. The company's Agentic AI layer automates investigations and enforces identity hygiene without requiring manual intervention. Sharelock targets enterprise customers and has received recognition from KuppingerCole's 2024 Leadership Compass for ITDR, where it was noted as the only European vendor included. The platform is also listed on Gartner Peer Insights under the user authentication market, where it has received high customer ratings across deployment, support, and product capabilities.
