TL;DR: Truffle Security shows that secrets leaked into source code remain live IAM credentials, not code defects, and fixing them requires rotation, revocation, and verification in the identity system rather than another code review. That reframes secret scanning as detection, not remediation, and shifts control ownership to IAM and lifecycle governance.
Editorial analysis by NHI Mgmt Group, based on content published by Truffle Security: “Secrets in Source Code Are Not A Code Security Problem”.
Key questions
Q: What should teams do first when they find an API key in source code?
A: Treat the discovery as a live credential incident, not a code defect.
Q: Why do exposed secrets keep creating risk after they are detected?
A: Because detection does not stop a credential from remaining valid, and exposed values often persist in repositories, logs, backups, and configuration files.
Q: How do organisations know whether secret scanning is actually working?
A: Look for fewer valid secrets left in circulation after detection, not just higher detection counts.
Practitioner guidance
- Prioritise live-key revocation workflows Route every discovered secret to the identity system first, then confirm the credential is no longer accepted before closing the case.
- Expand scanning beyond active branches Include old commits, deleted commits, dangling references, and non-code storage such as Slack, Jira, S3, and containers in secret discovery.
- Tighten key issuance and scope Reduce the default reach of newly generated API keys and make creation policy stricter so exposed credentials have less blast radius.
Bottom line: Exposed API keys are a credential governance problem because the real risk is continued authentication, not the fact that the secret appeared in code.
What's in the full article
Truffle Security's full article covers the operational detail this post intentionally leaves for the source:
- Examples of leaked keys surviving in branches, deleted commits, and cloned laptops
- Operational guidance for validating whether a compromised key is still live
- Direct workflows that connect secret discovery to IAM revocation actions
- Additional examples of secrets found in Slack, Jira, S3, and CI/CD systems

Secrets in source code are an IAM lifecycle problem, not a code security problem. The article is right to reject the idea that source control tooling can remediate a live credential. Once an API key is exposed, the meaningful control is whether the identity platform can revoke, rotate, and verify it quickly enough to reduce exposure. Practitioners should read this as a governance boundary, not a tooling preference.
A few things that frame the scale:
- Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them, according to the Ultimate Guide to NHIs.
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What is the difference between secret scanning and secret revocation?
A: Secret scanning finds exposure, while secret revocation removes the ability to authenticate with the exposed credential. Scanning reduces blind spots, but revocation is what actually breaks attacker reuse and shrinks blast radius.
