Best Non-Human Identity Security Platforms: Top 5 Ranking · segment · 7 min The emerging category governing service accounts, secrets, OAuth apps, and AI agents. By SWI Community Team · Updated 2026-07-03Scored on our [10-dimension rubric](https://startwithidentity.com/methodology/) Non-human identities now outnumber humans many times over and are the least-governed part of the attack surface. This emerging category focuses on discovering, owning, and right-sizing them, including AI agents. The five below are the platforms we profile. Scores follow our [10-dimension rubric](https://startwithidentity.com/methodology/) and editorial judgment. Each pick links to a full vendor profile. Read the [non-human identity security guide](https://startwithidentity.com/guides/machine-identity/non-human-identity-security/) and [securing AI agent identities](https://startwithidentity.com/guides/machine-identity/securing-ai-agent-identities/). 1 Discovery and governance of non-human identities across SaaS and cloud.

Best for: Teams connecting NHI governance to secret exposure Watch out: Younger vendor; validate scale and coverage [Read the full Entro Security review →](https://startwithidentity.com/vendors/ai-identity/entro-security/) 5 Workload identity and access management for secretless machine-to-machine access. Aembit issues short-lived, policy-based credentials for workloads and agents so services authenticate without stored secrets, a strong fit for teams securing machine-to-machine and agent access. Best for: Teams enforcing secretless, policy-based workload access Watch out: Access-focused; pair with discovery and governance [Read the full Aembit review →](https://startwithidentity.com/vendors/ai-identity/aembit/) ## At a glance # Vendor Score Best for 1 [Astrix Security](https://startwithidentity.com/vendors/ai-identity/astrix-security/) 4.5/5 Enterprises that need NHI discovery, ownership, and posture 2 [Token Security](https://startwithidentity.com/vendors/ai-identity/token-security/) 4.4/5 Enterprises prioritizing machine-first NHI and agent security 3 [Oasis Security](https://startwithidentity.com/vendors/ai-identity/oasis-security/) 4.4/5 Enterprises wanting NHIs governed with a dedicated platform 4 [Entro Security](https://startwithidentity.com/vendors/ai-identity/entro-security/) 4.2/5 Teams connecting NHI governance to secret exposure 5 [Aembit](https://startwithidentity.com/vendors/ai-identity/aembit/) 4.3/5 Teams enforcing secretless, policy-based workload access ## Frequently asked questions What are the best non-human identity security platforms in 2026? Astrix Security, Token Security, Oasis Security, and Entro Security lead on NHI discovery, ownership, and posture, while Aembit focuses on secretless workload and agent access. The category is new and consolidating quickly, so validate coverage for your environment. What is a non-human identity security platform? It is a tool that discovers, owns, right-sizes, and governs non-human identities (service accounts, API keys, OAuth apps, workloads, and AI agents) that secrets and certificate tools do not fully address. See our non-human identity security guide. Do I need one if I already use secrets management? Often yes. Secrets managers vault and rotate credentials, but they do not fully inventory every NHI, assign ownership, or right-size access across SaaS and cloud. NHI security platforms fill that governance gap. Independent and community-driven, no sponsorship.
