ShadowSecurityScanner
ShadowSecurityScanner is a free, open-source desktop tool for penetration testing and network vulnerability scanning on Windows, macOS, and Linux. It scans network hosts, servers, web applications, and network appliances using port checks, service and operating-system fingerprinting, and thousands of active security tests. Findings receive FIRST.org EPSS scores and are checked against the CISA Known Exploited Vulnerabilities catalog. Scan comparisons identify findings that are new, regressed, or resolved. Reports can be exported as PDF, HTML, SARIF, XML, or CSV, with SARIF described as suitable for GitHub code scanning. A signed update feed refreshes the audit catalog with daily CISA KEV updates, Nuclei, and curated advisories. The application runs locally, stores its database in the user profile, and has no cloud component or telemetry. It is distributed as one self-contained app, without agents or a database server. Listed requirements include Windows 10/11, macOS 11 or later on Apple Silicon, and Linux x64 or ARM64. Use is limited to authorized testing; denial-of-service tests are excluded.
