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.
Network reconnaissance teams and red teamers conducting large-scale asset discovery will get the most from MASSCAN because it scans entire IP ranges at line-rate speed where traditional port scanners timeout or require days to complete. The 25,424 GitHub stars and active use across major bug bounty platforms validates that it actually delivers the promised 10 million packets-per-second throughput. Skip this if you need vulnerability assessment or compliance reporting built in; MASSCAN finds what's listening, nothing more, and you'll chain it to other tools for context and remediation.
