ASRI (Attack Surface Reduction Index) by RunSafe Security is a tool designed to quantify and analyze the attack surface of software applications. It calculates a score by examining vulnerabilities in software packages, focusing on memory-related exploits in open source components. ASRI analyzes indicators such as severity and known exploits across software packages to provide a clear view of an organization's security posture. The system helps prioritize mitigation efforts, track security improvements, and quantify risks in external-facing software assets.
