Ermetic

Ermetic is a cloud security company founded in 2019 that pioneered cloud infrastructure entitlement management (CIEM) as part of a unified, identity-first cloud-native application protection platform (CNAPP) spanning AWS, Azure, and GCP. The platform provides full visibility into permissions and entitlements across multi-cloud environments, least-privilege and just-in-time access controls, anomaly detection against behavioral baselines, and compliance and cloud security posture management (CSPM). Ermetic raised roughly $100M from investors including Accel, Norwest Venture Partners, Glilot Capital Partners, and Target Global, and was acquired by Tenable in October 2023 for approximately $265M. The product now ships as Tenable Cloud Security; the ermetic.com domain redirects to Tenable, and the former Ermetic customer application (us.app.ermetic.com) exposes a login-gated REST API.

Ermetic is profiled on the APIs.io network. Tagged areas include Company, Security, Cloud Security, CIEM, and CNAPP.

Ermetic’s developer surface includes API reference, engineering blog, and 2 more developer resources.
