AppCheck Infrastructure Scanner is a commercial security scanning tool by AppCheck. Intruder XSS Scanner is a commercial security scanning tool by Intruder. Compare features, ratings, integrations, and community reviews side by side to find the best security scanning fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Startup and SMB security teams with limited scanning bandwidth should run Intruder XSS Scanner for its breadth across 75+ application vulnerabilities and 140,000+ infrastructure checks, all automated on a schedule you set once and forget. The authenticated scanning behind login pages and SPA support mean you're catching real-world XSS exposure in modern applications, not just the obvious entry points. Skip this if your priority is SAST integration into the developer IDE or if you need forensics-grade post-breach investigation; Intruder maps cleanly to continuous monitoring and risk identification, not incident response.
