What ShadowSecurityScanner is

ShadowSecurityScanner is a free, open-source desktop tool for authorized penetration testing and vulnerability scanning. It examines network hosts, servers, web applications, and network appliances using automated port scans, service and operating-system fingerprinting, and thousands of active security checks. Findings receive FIRST.org EPSS scores and are flagged when they appear in the CISA Known Exploited Vulnerabilities catalog. Compare scans to identify findings that are new, regressed, or resolved. Reports can be exported as PDF, HTML, SARIF, XML, or CSV; SARIF is described as suitable for GitHub code scanning. Its audit catalog refreshes from a signed feed that includes daily CISA KEV updates, Nuclei, and curated advisories. The app runs locally, stores its database in the user's profile, and has no cloud component or telemetry. It is distributed as one self-contained desktop app, without agents or a database server. Downloads are listed for Windows 10/11, macOS 11 or later on Apple Silicon, and Linux x64 or ARM64. Denial-of-service tests are intentionally excluded.
