What is the difference between reducing identity risk and eliminating it?

Reducing identity risk assumes some attacks will succeed and focuses on limiting damage after compromise. Eliminating identity risk means removing the main attack paths before they work, for example by using device-bound cryptographic credentials instead of reusable secrets that can be phished or replayed.

Why This Matters for Security Teams

Reducing identity risk and eliminating identity risk are not just different phrases, they describe different operating models. Reduction assumes compromise can still happen, so the goal is to contain blast radius with monitoring, least privilege, and response. Elimination pushes earlier: remove the reusable secret, remove the standing privilege, and remove the easy replay path before attackers can use it. For NHI programs, that distinction matters because service accounts, API keys, and automation tokens are often the first thing adversaries target.

NHIs are not a niche issue. In the Ultimate Guide to NHIs, NHI Management Group notes that 80% of identity breaches involved compromised non-human identities such as service accounts and API keys. That is why “risk reduction” alone often leaves the same attack path intact. Current guidance from NIST Cybersecurity Framework 2.0 still favours measurable governance, but practitioners should recognise that governance does not equal path removal. In practice, many security teams encounter identity compromise only after a secret has already been reused, exfiltrated, or replayed, rather than through intentional elimination of the underlying exposure.

How It Works in Practice

Elimination is usually achieved by changing the credential model, not by adding more controls around the same weak one. A reusable secret can be phished, copied from code, or replayed later. A device-bound cryptographic credential changes that equation because it is tied to the workload or device and is far harder to steal in a usable form. For agents and automated systems, that is especially important: the identity should prove what the workload is, not just what token it currently holds.

That is why NHI programs increasingly pair workload identity with short-lived issuance and runtime policy checks. Instead of broad standing access, the system issues Top 10 NHI Issues style controls such as JIT credentials, narrow scopes, and automatic revocation when the task ends. In a mature design, the agent receives an ephemeral credential, completes a bounded action, and loses access before the next task. This is aligned with the Zero Trust idea that access should be continuously evaluated, not granted once and trusted forever. The same approach is reinforced by the OWASP NHI Top 10, which treats exposed secrets, excessive privilege, and weak runtime controls as recurring failure modes.

  • Replace long-lived API keys with short-lived workload credentials.
  • Bind identity to cryptographic proof, not to a shared secret copied into code.
  • Use runtime authorisation checks so access matches the current task, not a static role.
  • Revoke or expire credentials automatically after use or after a short TTL.

This approach fits the spirit of NIST Cybersecurity Framework 2.0, but the implementation detail matters: if the same secret still exists in code, config, or CI/CD, the control only reduces risk. These controls tend to break down in legacy batch jobs and shared integration environments because multiple systems depend on the same credential and cannot cleanly enforce per-task revocation.

Common Variations and Edge Cases

Tighter elimination controls often increase operational overhead, requiring organisations to balance lower exposure against integration complexity and availability risk. That tradeoff is real, especially where vendors, legacy schedulers, or third-party automations still expect persistent credentials. In those environments, full elimination may not be immediately possible, so teams fall back to staged reduction while they replace the weakest paths first.

There is also no universal standard for every use case yet. Some systems can adopt full workload identity and ephemeral secrets quickly, while others need transitional controls such as vaulting, aggressive rotation, and fine-grained PAM. Best practice is evolving for agentic workloads in particular, because autonomous software can chain tools, change behaviour, and exceed the assumptions of classic RBAC. For that reason, NHI Management Group recommends treating elimination as the design target and reduction as a temporary state. Research such as 52 NHI Breaches Analysis and Ultimate Guide to NHIs shows why: when secrets remain reusable, compromise usually becomes a matter of time, not sophistication.
