About GitHub's security features
GitHub has security features that help keep code and secrets secure in repositories and across organizations. Some features are available for all repositories and others are only available with a GitHub Advanced Security license.
The GitHub Advisory Database contains a curated list of security vulnerabilities that you can view, search, and filter. For more information about advisory data, see "Browsing security vulnerabilities in the GitHub Advisory Database."
Available with Advanced Security
Code scanning alerts
Automatically detect security vulnerabilities and coding errors in new or modified code. Potential problems are highlighted, with detailed information, allowing you to fix the code before it's merged into your default branch. For more information, see "About code scanning."
Secret scanning alerts
View any secrets that GitHub has found in your code. You should treat tokens or credentials that have been checked into the repository as compromised. For more information, see "About secret scanning."
