Secret scanning is the process of searching code, repositories, logs, files, and workflows for exposed passwords, API keys, tokens, and other sensitive credentials. It matters because leaked secrets often become one of the fastest paths to compromise.
What is Secret Scanning?
Secret scanning uses automated detection patterns and validation logic to identify sensitive credentials in places they should not be stored. Teams use it in source control, CI/CD pipelines, ticketing systems, cloud configurations, and collaboration environments.
What Secret Scanning Commonly Finds
Common findings include API keys, cloud access tokens, database passwords, private keys, hardcoded secrets, and connection strings committed to repositories or shared in plain text.
Secret Scanning vs. Secrets Management
Secret scanning finds exposed credentials. Secrets management governs how credentials should be stored, rotated, and protected properly.
Frequently Asked Questions
Why is secret scanning important?
Because exposed secrets can create immediate, high-impact access paths for attackers and are often easy to overlook during fast-moving development.
Does finding a secret always mean compromise happened?
No, but it should usually trigger rotation, review, and validation because exposure risk can be significant even without confirmed abuse.
