What is Shadow Security Scanner?
ShadowSecurityScanner is a free, open-source penetration testing and network vulnerability scanner that runs entirely on your machine with no cloud or telemetry. It fingerprints services and operating systems, runs 6,000+ security checks, and ranks findings by real-world exploit probability using EPSS and CISA KEV data instead of raw severity scores. Built for security engineers, sysadmins, red teams, and DevSecOps pipelines who need privacy-first vulnerability discovery.
