Best non-human identity (NHI) management tools in 2026

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

August 2026: Vendor map expanded from 7 to 12 with directory profiles for every listed vendor. M&A statuses updated to verified terms: Cisco's Astrix acquisition closed June 2026 (~$400M reported); SailPoint's Entro acquisition closed June 2026; Cyera agreed to acquire Oasis for a reported ~$1B (July 2026, pending); Snowflake announced an agreement to acquire Natoma (May 2026).
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 August 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	Vaultless SaaS secrets management with certificate and machine-identity features, plus recently added AI-agent capabilities.
Astrix Security (Cisco)	NHI discovery & posture	Maps app-to-app connections and NHI risk; acquisition by Cisco completed June 2026 (reported ~$400M) — standalone license sales have ended, expect Cisco-portfolio integration.
Clutch Security	NHI discovery, lineage & agent governance	Identity Lineage graph ties each NHI to its origin and consumers; Agentic AI Governance module covers sanctioned and shadow agents.
Corsha	Machine identity for OT & defense	Machine identity provider with dynamic m-MFA authentication, purpose-built for industrial, defense, and critical-infrastructure networks.
Defakto	SPIFFE-based workload identity	Formerly SPIRL; issues short-lived, verifiable workload identities in place of static credentials, with an AI-agent module.
Entro Security (SailPoint)	NHI & secrets posture	Secrets and NHI discovery across clouds, code, vaults, and collaboration tools; acquired by SailPoint (closed June 2026) as the NHI/secrets layer of its Agentic Fabric.
Keycard	AI-agent access control plane	Short-lived, task-scoped credentials for AI agents and MCP servers, with published pricing — rare in this category.
Natoma	MCP & AI-agent governance	Governed MCP-server deployment and agent IAM on NHI-management roots; Snowflake announced an agreement to acquire Natoma in May 2026.
Oasis Security	NHI discovery, posture & lifecycle	Deep lifecycle coverage including secret rotation and AI-SPM; Cyera agreed in July 2026 to acquire Oasis for a reported ~$1B (pending close).
P0 Security	JIT cloud access for humans, NHIs & agents	Just-in-time, short-lived access and IAM posture across clouds, Kubernetes, and databases — a cloud-native alternative to standing-privilege PAM.
Token Security	Machine-first identity security	NHI inventory, ownership mapping, and Intent-Based AI Agent Security (March 2026); one of the few notable independents left after the consolidation wave.

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.
