Without visibility, teams cannot answer who owns each identity, where it is used, or whether it still needs access. That leads to orphaned accounts, excessive permissions, failed rotations, and delayed response when a secret is exposed. The result is a larger attack surface and weaker accountability across cloud and application estates.
Why This Matters for Security Teams
When service accounts and machine credentials are invisible, security teams lose the basic inventory needed to govern access, detect misuse, and prove ownership. That makes it impossible to distinguish a legitimate automation account from an abandoned one, or a low-risk integration from a high-value path into production. The result is not just more secrets, but more uncertainty around which secrets matter most.
Current guidance from the OWASP Non-Human Identity Top 10 and NHI Management Group’s research on the Guide to the Secret Sprawl Challenge shows that the lack of visibility is a root cause, not just an operational inconvenience. Once ownership is unclear, rotation stalls, permissions drift, and incident response slows because responders cannot quickly identify where a compromised credential is deployed. In practice, many security teams discover these gaps only after an exposed key is already being used elsewhere in the environment.
How It Works in Practice
Visibility starts with building an authoritative inventory of non-human identities, then connecting each identity to an owner, purpose, and runtime location. That includes service accounts in directories, workload identities in cloud platforms, API keys embedded in applications, and certificates used by automated systems. Without that linkage, teams cannot confidently answer whether a credential is active, whether it is over-privileged, or whether it is safe to revoke.
Practitioners usually need three controls working together. First, discovery from cloud logs, secret stores, CI/CD systems, and application platforms. Second, classification that distinguishes human accounts from NHI workloads and maps them to business services. Third, continuous monitoring so changes in usage, privilege, or location are detected quickly. This is where the most useful security posture reports emerge, because they reveal the difference between known automation and hidden sprawl.
NHI Management Group’s 52 NHI Breaches Analysis and Ultimate Guide to NHIs — Static vs Dynamic Secrets both point to the same operational pattern: hidden credentials turn into hidden risk. Once an attacker finds a secret, they often move laterally through interconnected services faster than a human review cycle can react. That is why NIST control intent in the NIST SP 800-53 Rev 5 Security and Privacy Controls is best translated into a living inventory and response process, not a one-time spreadsheet exercise. These controls tend to break down when credential issuance is decentralized across DevOps pipelines and cloud teams because no single system sees the full identity lifecycle.
Common Variations and Edge Cases
Tighter credential governance often increases operational overhead, requiring organisations to balance faster delivery against stronger accountability. That tradeoff is especially visible in environments with ephemeral workloads, multi-cloud estates, and third-party integrations, where service accounts are created quickly and forgotten just as quickly.
There is no universal standard for this yet, but current guidance suggests that teams should treat high-risk machine credentials differently from low-risk internal automation. For example, long-lived keys in legacy applications may need compensating controls such as stricter monitoring, segmented access, and accelerated retirement plans, while modern workloads should move toward short-lived secrets and workload identity. The OWASP Non-Human Identity Top 10 is useful here because it frames visibility failures as an identity problem, not just a secrets hygiene problem.
Edge cases also appear when ownership is split across platform, application, and security teams. In those situations, the missing control is often not technology but governance: someone must own registration, review, and retirement of each service account. NHI Management Group’s Guide to the Secret Sprawl Challenge is a practical reminder that untracked credentials rarely stay contained, and the lack of visibility becomes most dangerous when secrets are copied into pipelines, scripts, and non-production environments without a clear decommissioning path.

This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10, OWASP Agentic AI Top 10 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0 and NIST AI RMF set the governance and control requirements practitioners need to meet.
