Allstar
Allstar is a GitHub App that continuously monitors GitHub organizations or repositories for adherence to security best practices. If Allstar detects a security policy violation, it creates an issue to alert the repository or organization owner. For some security policies, Allstar can also automatically change the project setting that caused the violation, reverting it to the expected state.
