CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise teams managing WordPress, Drupal, or other CMS platforms need AppCheck CMS Security Scanning because it actually crawls modern JavaScript-heavy frontends instead of stopping at static HTML, catching XSS and IDOR flaws that traditional scanners miss. The scriptable browser interface handles multi-stage authentication, and continuous scanning with threat alerts keeps you honest between major releases. Skip this if your infrastructure is mostly API-first microservices with minimal CMS exposure; you'll pay for capabilities you don't need and gain less than a general-purpose DAST platform would offer.
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.
