Allstar is a GitHub App designed to continuously monitor GitHub organizations and repositories for compliance with security best practices. The tool automatically detects security policy violations within GitHub environments and creates issues to notify repository or organization owners of potential security concerns. Allstar provides granular control over security monitoring by allowing users to specify which files and settings should be monitored for security compliance. Users can configure security policies at both the organization and repository levels, with customizable handling of policy violations. The application supports extensibility through the development and contribution of new security policies. Organizations can tailor the monitoring scope to their specific security requirements and choose appropriate response actions when violations are detected. Allstar operates as part of the OpenSSF (Open Source Security Foundation) organization, focusing on improving security practices across GitHub-hosted projects through automated monitoring and alerting capabilities.
