Non-Human Identity Tools 2026
Non-Human Identity (NHI) security covers the discovery, governance, and protection of every identity in your environment that is not a person: service accounts, API keys, OAuth tokens, certificates, secrets, machine and workload identities, and the newer wave of AI agent identities. These vastly outnumber human identities in most enterprises, and they tend to be over-permissioned, rarely rotated, and invisible to IAM tooling built for employees. The tools here exist to inventory non-human identities across cloud and SaaS, map their entitlements, flag stale or risky credentials, and enforce least privilege before one of them becomes the breach path. If you are a CISO who can name every privileged user but cannot say how many service accounts hold admin rights, this is the category that closes that gap.

How to choose Non-Human Identity tools
- Examine the discovery surface. A tool that sees cloud IAM roles but misses SaaS OAuth grants, CI/CD tokens, and on-prem service accounts leaves your largest gaps unmanaged.
- Look for entitlement and blast-radius context, not just an inventory. Knowing a key exists matters less than knowing what it can touch and which credentials are over-permissioned or dormant.
- Test how it handles credential lifecycle. Detecting stale, hardcoded, or shared secrets is the baseline, but rotation guidance and ownership attribution are what actually reduce risk.
- Decide whether you need agentic identity coverage now or soon. AI agents and autonomous workloads spawn short-lived, fast-multiplying identities that older NHI scanners were never designed to track.
- Weigh integration depth with your existing secrets manager, CSPM, and IdP rather than treating this as a replacement. The best NHI tools enrich what you already run instead of standing up a parallel system.
- Separate detection from enforcement. Some tools stop at visibility and risk scoring; others can revoke, rotate, or block. Match the automation level to how much you trust acting on machine identities without breaking production.
Non-Human Identity Tools FAQ
Common questions about Non-Human Identity tools, selection guides, pricing, and comparisons.
It is the practice of discovering, governing, and securing every identity that is not a person: service accounts, API keys, OAuth tokens, certificates, secrets, and machine, workload, and AI agent identities. NHI security tools inventory these identities across cloud and SaaS, map their permissions, flag stale or over-privileged credentials, and enforce least privilege so machine identities do not become an unmonitored breach path.
PAM controls privileged human and some service-account access through sessions and vaulting. Secrets managers store and rotate credentials. NHI security sits above both: it discovers the full population of machine identities wherever they live, attributes ownership, scores risk, and governs entitlements across systems. It often integrates with your secrets manager and IdP rather than replacing them, supplying the inventory and posture layer those tools lack.
Machine identities now outnumber human ones in most enterprises, often by ten to one or more, and they behave differently. They are created automatically, rarely rotated, frequently over-permissioned, and largely invisible to IAM tooling built around employee joiners, movers, and leavers. Generic identity governance was never designed to discover an orphaned API key or a dormant service account, which is exactly where attackers look.
Start with discovery breadth: it should see across cloud IAM, SaaS OAuth grants, CI/CD systems, and on-prem service accounts, not one silo. Then prioritize entitlement context and blast-radius analysis, credential lifecycle detection, integration with your existing secrets manager and IdP, and whether you need agentic AI identity coverage. Finally, decide how much enforcement you want versus visibility alone.
Possibly. A CSPM sees cloud misconfigurations and a secrets manager stores credentials, but neither gives you a unified inventory of non-human identities with ownership, usage, and entitlement risk across cloud and SaaS together. If you cannot answer how many service accounts hold admin rights or which tokens sit unused, a dedicated NHI tool fills that gap. If your estate is small and single-cloud, your existing tools may be enough for now.
