Best Non-Human Identity Security Platforms: Top 5
The emerging category governing service accounts, secrets, OAuth apps, and AI agents.
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 and editorial judgment. Each pick links to a full vendor profile. Read the non-human identity security guide and securing AI agent identities.
Discovery and governance of non-human identities across SaaS and cloud.
Astrix discovers service accounts, API keys, OAuth apps, and other NHIs, maps their access and ownership, and flags over-privileged or risky ones, a leading pick for getting visibility and control over the NHI sprawl.
Best for: Enterprises that need NHI discovery, ownership, and posture

Machine-first identity security built around NHIs and AI agents.
Token Security takes a machine-first approach to inventorying and securing non-human identities, including the fast-growing population of AI agents, with a focus on lifecycle and least privilege.
Best for: Enterprises prioritizing machine-first NHI and agent security

Dedicated NHI management with discovery, posture, and lifecycle.
Oasis provides a dedicated non-human identity management platform covering discovery, posture, and remediation across environments, aimed at teams that want NHIs governed like human identities.
Best for: Enterprises wanting NHIs governed with a dedicated platform
Watch out: Focused on NHI governance; pair with secrets tooling
Non-human identity and secrets security with strong secret context.
Entro combines NHI discovery with deep secrets context, tracing where secrets live, how they are used, and whether they are exposed, which helps teams connect NHI governance to secret risk.
Best for: Teams connecting NHI governance to secret exposure
Watch out: Younger vendor; validate scale and coverage
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

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.
