CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Development teams maintaining legacy Swagger-ui implementations should use XSSwagger because it fills a narrow but real gap: detecting XSS flaws in older API documentation interfaces that modern scanners overlook. The tool is free and requires no integration overhead, making it a logical paired scan alongside your primary SAST tool. Skip this if you're running current Swagger versions or don't expose Swagger-ui publicly; the specificity that makes it useful also means it won't catch XSS vulnerabilities anywhere else in your application.
