Defakto Security

Defakto Security is a cybersecurity company founded in 2022 by Danny Oliveri and Eli Nesterov, with its headquarters located in Palo Alto, California. Initially launched as SPIRL, the company rebranded to Defakto to reflect its focus on establishing a modern standard for non-human identity security.

Business/Product Breakdown

Defakto Security operates a non-human identity and access management platform that replaces static secrets, API keys, and overprivileged service accounts with short-lived, policy-bound identities issued on demand. Built on open protocols including SPIFFE, the platform secures automated interactions for workloads, CI/CD pipelines, multi-cloud environments, and AI agents by embedding verifiable identities into every non-human actor. Core capabilities include automated discovery of machine identities, just-in-time credential issuance, continuous posture assessment, and revocation workflows that integrate natively into existing development pipelines. The system provides centralized audit trails and policy enforcement without requiring changes to underlying code or infrastructure.
