Entro Security

Entro Security builds an agentless SaaS platform that discovers, classifies, and protects non-human identities and secrets — API keys, access tokens, and increasingly AI agent credentials — across cloud services and data networks. The platform covers detection, contextualization, and rapid remediation of leaked secrets across the software development lifecycle, full lineage mapping of non-human identities with human ownership attribution, and continuous monitoring for behavioral anomalies through its NHIDR (Non-Human Identity Detection and Response) capability.

Entro Security is headquartered in Cambridge, Massachusetts and has raised $24 million in total venture funding, including a $6 million seed round and an $18 million Series A. The company reports being trusted by global Fortune 500 enterprises and has built specific coverage for financial services environments where secrets sprawl carries acute regulatory risk.

Entro competes directly with Defakto, Astrix Security, Oasis Security, and other non-human identity vendors chasing the same rapidly-growing category, driven by the fact that machine identities now vastly outnumber human ones in most enterprises. Its differentiation is unifying secrets management and non-human identity governance in one agentless platform rather than treating them as separate problems, though as a Series A company its customer base and independent validation are still developing.
