GitHub secret scanning protects users by searching repositories for known types of secrets such as tokens and private keys. By identifying and flagging these secrets, our scans help prevent data leaks and fraud.
We have partnered with MaxMind to scan for their license keys and help secure our mutual users on public repositories. MaxMind keys allow users to run queries against minFraud®, GeoIP®, and GeoLite services, and download GeoIP and GeoLite databases. GitHub will forward license keys found in public repositories to MaxMind, who will then email the user about the leaked key. You can read more information about MaxMind keys here.
All users can scan for and block MaxMind keys from entering their public repositories for free with push protection. GitHub Advanced Security customers can also scan for and block MaxMind keys in their private repositories.
