Obsidian Security is a SaaS security platform founded in 2017 that focuses on protecting enterprise organizations' SaaS application ecosystems. The company provides capabilities spanning SaaS Security Posture Management (SSPM), identity protection, data protection, and threat detection across SaaS environments. The platform connects to SaaS applications via agentless API integrations, giving security teams visibility into user activity, application configurations, third-party integrations, and data flows without requiring endpoint agents. Core capabilities include detecting misconfigurations, identifying risky third-party app connections, monitoring user behavior for threats, and enabling incident response workflows within SaaS environments. Obsidian targets mid-market to large enterprise customers, with notable traction across financial services, telecommunications, healthcare, manufacturing, hospitality, and software sectors. The company reports protecting approximately 49 million identities and managing around 340,000 applications, stopping roughly 3,450 threats per month across its customer base. The company raised a $90 million Series C round in 2022 and has since expanded operations into EMEA and APAC regions. In 2025, Obsidian is expanding its data center footprint internationally and developing AI Security solutions alongside new mid-market product offerings. The platform integrates with incident response workflows and has established partnerships with major incident response firms globally.
