Secrets sprawl increases risk because credentials are duplicated across endpoints, repositories, CI pipelines, and secret managers, making ownership and revocation difficult. Fragmented control weakens visibility, slows remediation, and expands the window in which exposed credentials remain usable. In practice, the more places secrets live, the harder it is to prove they are controlled.
Why This Matters for Security Teams
secrets sprawl is not just a storage problem. It is an operational control problem that turns routine development work into a recurring exposure surface. When credentials are duplicated across code, CI pipelines, ticketing tools, laptops, and secret managers, no single team can confidently answer where a secret exists, who can use it, or how fast it can be revoked. That weakens incident response and undermines least privilege. Guidance from the OWASP Non-Human Identity Top 10 aligns with what NHI Management Group sees in practice: unmanaged machine credentials tend to outlive the workflows that created them. The risk is not only exposure, but persistence after exposure.
NHIMG research on the State of Secrets Sprawl 2026 shows why this has become harder to dismiss as edge cases. In modern development environments, secrets now appear in repositories, collaboration tools, and AI-assisted workflows, which means control boundaries are no longer aligned to system boundaries. In practice, many security teams encounter this only after a credential has already been reused outside its intended path, rather than through intentional lifecycle control.
How It Works in Practice
operational risk rises when secrets are handled as isolated assets instead of as a managed identity lifecycle. A token stored in a repository, copied into a CI variable, and pasted into a support ticket has three separate owners in theory and none in practice. That fragmentation breaks revocation, auditability, and dependency tracking. The NIST Cybersecurity Framework 2.0 emphasises governance, asset visibility, and continuous monitoring, but those outcomes depend on knowing where secrets exist and which workloads actually use them.
For development environments, the practical response is to reduce persistence and centralise control signals:
- Issue short-lived credentials for builds, deployments, and agent tasks instead of long-lived shared secrets.
- Bind secrets to workload identity so access is tied to the executing service, pipeline, or agent, not just a static string.
- Track secret provenance across repositories, CI/CD, chat, tickets, and artifact stores so discovery is not limited to source code.
- Automate rotation and revocation so a leaked value becomes unusable quickly, even when it cannot be removed immediately.
This is where NHI-specific guidance matters. The Ultimate Guide to NHIs — Static vs Dynamic Secrets frames the real operational difference between a secret that is merely stored and one that is actively governed. Static secrets create hidden dependency chains, while dynamic secrets make expiry, ownership, and scope visible at runtime. Teams that pair secret scanning with workload identity, policy enforcement, and immediate invalidation are better positioned to contain leaks before they become multi-system incidents. These controls tend to break down in large CI/CD estates with shared runners and ad hoc scripts because the same credential is often reused across too many unrelated jobs.
Common Variations and Edge Cases
Tighter secret controls often increase developer friction, requiring organisations to balance speed against the operational cost of false positives, break-glass requests, and pipeline redesign. That tradeoff is real, especially where legacy applications still depend on environment variables or shared service accounts. Current guidance suggests prioritising the highest-risk paths first: production credentials, CI/CD runners, collaboration tools, and any secret that can reach cloud control planes.
Edge cases also matter. Secrets hidden outside code are easy to miss, which is why NHIMG’s State of Secrets Sprawl 2026 is so useful for practitioners tracking the broader exposure surface. GitHub scanning alone is not enough when credentials are being exchanged in tickets or copied into AI tooling. Likewise, the CI/CD pipeline exploitation case study illustrates how a single compromised runner can turn fragmented secret management into full-path lateral movement. Best practice is evolving, but there is no universal standard yet for how aggressively teams should replace shared static secrets in every legacy integration.
Standards & Framework Alignment

OWASP Non-Human Identity Top 10 and CSA MAESTRO address the attack and risk surface, while NIST CSF 2.0, NIST AI RMF and NIST Zero Trust (SP 800-207) set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Secret sprawl is a core non-human identity exposure and lifecycle problem. |
| NIST CSF 2.0 | ID.AM-1 | You cannot govern secrets you have not identified across environments. |
| NIST AI RMF | AI-assisted development changes where secrets appear and how fast they spread. | |
| NIST Zero Trust (SP 800-207) | Fragmented secrets undermine zero trust by creating broad, persistent trust relationships. | |
