ManageEngine Vulnerability Manager Plus vs ShadowSecurityScanner

ManageEngine Vulnerability Manager Plus identifies and assesses vulnerabilities across a network and helps teams prioritize and remediate them. Its risk prioritization uses AI-based scores, CVSS severity, EPSS and active attack trends. It includes out-of-the-box policies for more than 130 CIS benchmarks and supports downloading, testing and deploying patches across operating systems and more than 1,500 third-party applications. Pre-built, tested scripts can mitigate zero-day vulnerabilities. The product can discover network devices, scan firmware for vulnerabilities and remediate identified threats, but network-device management is on-premises only and requires extra licenses. Vulnerability Manager Plus supports Windows and Linux; macOS support is limited to patch management. It offers a free edition and a 30-day trial with unlimited endpoints. Listed annual prices include Professional On-Premises at $695 a year and Professional Cloud at $895 a year, each for 100 workstations and one technician. Enterprise options are listed at $1,195 a year on-premises and $1,545 a year in the cloud, on the same workstation and technician basis.

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.
