AppCheck Infrastructure Scanner
SMBs and mid-market teams without dedicated vulnerability management staff should pick AppCheck Infrastructure Scanner for its unlimited scanning and users, removing seat-based licensing friction that kills adoption. The proprietary VulnFeed database detects over 20,000 products and tens of thousands of CVEs with authenticated scanning that catches what surface-level tools miss, and RBAC plus role-based reporting let security generalists delegate tasks without handing out admin access. Skip this if your primary need is web application scanning; the infrastructure focus is strong, but the web scanning is secondary to the core network and data center mission.
Security teams evaluating OWASP compliance without budget will find BlackWidow's free tier genuinely useful for baseline web application scanning. The combination of OSINT reconnaissance and automated fuzzing catches common misconfigurations and injection flaws that manual testing alone misses, and the 1,708 GitHub stars suggest real adoption among development teams, not just hobbyists. Skip BlackWidow if your organization needs API security, authentication bypass detection, or compliance reporting; this is a scrappy scanner for developers and small security ops who want vulnerability discovery, not a WAF replacement or compliance engine.
