CST VerdictBased 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.
AppSec teams running frequent web application assessments will get the most from CORStest because it isolates CORS misconfigurations that slip past broader vulnerability scanners, and the free pricing means you can run it as often as you want without licensing friction. With 419 GitHub stars and active maintenance, it's trusted enough for inclusion in scanning pipelines where CORS-specific coverage matters. Skip this if your org needs a generalist scanner that also catches SQL injection, XSS, and authentication flaws in one tool; CORStest does one thing and won't replace your primary web application scanner.
