Best Non-Human Identity Security Platforms: Top 5

The emerging category governing service accounts, secrets, OAuth apps, and AI agents.

By SWI Community Team · Updated 2026-10-16Scored on our 10-dimension rubric

Non-human identity platforms are bought because nobody can say how many service accounts, API keys, OAuth grants and AI agents exist, who owns them, or what they can reach. In 2026 the harder question is not which tool finds them best, but which of these companies will still sell you that tool next year.

How we ranked

Four tests, in this order.

Discovery breadth. Which SaaS, cloud and on-premises systems the platform connects to, and whether it finds third-party OAuth grants and AI agent connections, not only cloud service accounts.

Ownership and remediation. Inventory is the easy half. We score whether a platform attributes an owner and drives rotation, right-sizing and decommissioning, or stops at a dashboard.

Posture versus runtime. Astrix Security, Token Security, Oasis Security and Entro Security find and govern. Aembit brokers access at runtime with short-lived credentials. They solve different halves of the problem, and mature programs run one of each.

Who owns the vendor. Three of the five changed hands, or agreed to, in 2026.

Applied to this category

Consolidation is the story. Cisco closed its Astrix acquisition on 29 June 2026, and Astrix has ended standalone sales of new licenses; the capability is being folded into Duo, Splunk and Cisco Identity Intelligence. SailPoint closed its Entro acquisition the same day and says Entro stays available as a standalone offering while integration continues. Cyera signed a letter of intent on 28 July 2026 to acquire Oasis for about 1 billion dollars; it has not closed. Token Security and Aembit remain independent and VC-backed.

None of the five is an identity provider, and none publishes pricing. All sell quote-based subscriptions behind a proof of value, so budget for a sales cycle.

Quick picker by scenario

  • You already buy from Cisco: the Astrix capability, now purchased through Cisco.
  • You run SailPoint for governance: Entro, which now feeds SailPoint's agent access layer.
  • You need rotation and offboarding, not just inventory: Oasis, with the pending Cyera deal on your risk register.
  • You want an independent vendor focused on AI agents: Token Security, accepting a small reference base. See Token Security vs Astrix Security.
  • You want secrets out of workload-to-workload calls: Aembit, paired with one of the discovery tools.

1
Astrix Security4.5/5 overall

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. Cisco closed its acquisition of Astrix on 29 June 2026 and is folding it into Duo, Splunk and Cisco Identity Intelligence.

Best for: Enterprises that need NHI discovery, ownership, and posture

Watch out: Cisco-owned since June 2026 and no longer sold standalone; buy through Cisco

2
Token Security4.4/5 overall

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

3
Oasis Security4.4/5 overall

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: Cyera signed a letter of intent to acquire it in July 2026; not yet closed

4
Entro Security4.2/5 overall

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: Now part of SailPoint (June 2026); still offered standalone for now

5
Aembit4.3/5 overall

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.
Can I still buy Astrix Security?
Not as a standalone product. Cisco closed its acquisition on 29 June 2026 and Astrix ended standalone sales of new licenses on 30 June 2026. Existing customers keep service under their current agreements, and the capability is being folded into Duo, Splunk and Cisco Identity Intelligence.
What is the difference between NHI posture tools and workload access tools?
Posture tools such as Astrix, Token Security, Oasis and Entro discover non-human identities, attribute owners and flag over-privilege. Workload access tools such as Aembit issue short-lived credentials at runtime so workloads stop storing secrets. Most programs need both.
