ShadowSecurityScanner
What it is
ShadowSecurityScanner is a free, open-source desktop tool for penetration testing and network vulnerability scanning. It runs on Windows, macOS, and Linux, examining network hosts, servers, web applications, and network appliances. Scans combine automated port checks, service and operating-system fingerprinting, and thousands of active network and web-application security checks. Findings receive FIRST.org EPSS scores and are flagged 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; SARIF is described as suitable for GitHub code scanning. The audit catalog refreshes from a signed feed containing daily CISA KEV updates, Nuclei, and curated advisories. The application runs on the user’s machine, stores its database in the user profile, and has no cloud component or telemetry. It is distributed as one self-contained desktop app without agents or a database server. Downloads list Windows 10/11, macOS 11 or later for Apple Silicon, and Linux x64 or ARM64. The maker limits use to authorized security testing and excludes denial-of-service tests.
