Best non-human identity (NHI) management tools in 2026
Last updated July 2026. Vendors are listed alphabetically — this page ranks approaches, not logos. No placement on this page is sponsored.
Quick answer
What are the best NHI management tools in 2026?
Short answer
There is no single "best" — the market splits into NHI discovery/posture platforms (Oasis, Astrix/Cisco, Entro, Token Security), workload access brokers (Aembit), lifecycle/governance specialists (Natoma), and secrets-first platforms (Akeyless, HashiCorp Vault). Shortlist by which problem dominates your estate.
- Best for
- Security teams whose service accounts, API keys, OAuth grants, and AI agents outnumber their people — which is nearly everyone.
- When to choose
- Choose a posture platform when you can't inventory your NHIs; a workload broker when services need secretless access; a secrets platform when credential storage/rotation is the gap.
- When not to choose
- Don't buy an NHI platform to solve a human-identity problem — workforce IAM, IGA, and PAM are different categories with mature tooling.

What changed in this market
- July 2026: Page published. Category context: Cisco's reported acquisition of Astrix Security and Oasis Security's reported $120M Series B underline rapid consolidation; CyberArk's machine-identity assets continue moving into Palo Alto Networks' Idira line.
Who does what: the NHI vendor map
Focus areas below summarize each vendor's own public positioning as of July 2026; verify capabilities in a proof-of-value on your environment. Vendors are listed alphabetically.
| Vendor | Primary focus | What to know |
|---|---|---|
| Aembit | Workload IAM / access broker | Policy-based, secretless access between workloads — closer to "IAM for services" than to secrets vaulting. |
| Akeyless | Secrets & machine identity platform | SaaS secrets management with certificate and machine-identity features; an incumbent-adjacent entry into NHI. |
| Astrix Security (Cisco) | NHI discovery & posture | Maps third-party app-to-app connections and NHI risk; reported as acquired by Cisco in 2026 — expect roadmap integration. |
| Entro Security | NHI & secrets posture | Inventory, exposure detection, and lifecycle context for secrets and non-human identities. |
| Natoma | NHI lifecycle & governance | Provisioning-style lifecycle management applied to non-human identities and their owners. |
| Oasis Security | NHI discovery, posture & lifecycle | One of the category's most-funded independents (a reported $120M Series B in 2026); broad NHI inventory and remediation. |
| Token Security | Machine-first identity security | Machine-identity inventory and ownership mapping oriented to security operations. |
Established platforms to weigh alongside the specialists
| Platform | What to know |
|---|---|
| CyberArk (Palo Alto Networks "Idira") | PAM incumbent with machine-identity/secrets lines; being folded into Palo Alto's Idira identity portfolio — roadmap in transition. |
| HashiCorp Vault | The default self-managed secrets engine; strong workload identity primitives, but posture/discovery is not its job. |
| Teleport | Infrastructure access for humans and machines with short-lived certificates. |
How should you shortlist an NHI tool?
- Name the dominant estate. Cloud workloads, SaaS-to-SaaS OAuth grants, CI/CD secrets, or AI agents — each pulls the shortlist toward different vendors.
- Demand an inventory proof-of-value. The differentiator in this category is discovery quality on your environment, not the demo environment.
- Check ownership mapping. Finding 40,000 NHIs is easy; attributing each to an accountable human owner is the hard, valuable part.
- Price the remediation loop. Posture findings without lifecycle actions (rotation, decommissioning, scoping) become another unread dashboard.
- Stress-test M&A exposure. The category consolidated fast in 2025–2026. Ask about roadmap independence, contract assignment clauses, and data egress before you sign.
Frequently asked questions
What is non-human identity (NHI) management?
NHI management is the discovery, governance, and lifecycle control of identities that aren't people: service accounts, API keys, OAuth app grants, workload identities, certificates, and AI agents. In most organizations NHIs outnumber human identities by an order of magnitude and have no owner, no rotation, and no offboarding — which is why the category emerged.
How is NHI different from machine identity or secrets management?
Secrets managers (e.g. Vault, Akeyless) store and issue credentials. Machine identity has historically meant certificates and workload auth. NHI platforms sit above both: they discover every non-human identity across clouds and SaaS, map which ones are over-privileged, stale, or ownerless, and drive remediation and lifecycle. Many buyers need a secrets manager AND an NHI posture layer.
Do AI agents count as non-human identities?
Yes — AI agents are the fastest-growing class of NHI, and the least governed. Agents need scoped credentials, an accountable human owner, and auditable activity trails. Several NHI vendors now market agent-specific capabilities; see our AI agent identity comparison for that slice of the market.
How should a security team shortlist NHI tools in 2026?
Start from your dominant estate (cloud workloads vs SaaS-to-SaaS grants vs secrets sprawl), demand a proof-of-value inventory on your own environment, and check M&A exposure — the category is consolidating quickly, so ask hard questions about roadmap independence and contract protections.
