CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
AppCheck CMS Security Scanning
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.
Frontend security teams hunting DOM XSS in single-page applications should use DOMdig because it combines static and dynamic analysis with fuzz testing to actually exploit vulnerabilities instead of just flagging suspicious patterns. The free pricing and 415 GitHub stars mean low friction for teams already living in CI/CD pipelines, though you'll need developers comfortable reading and acting on JavaScript-specific findings. Skip this if you need a full SAST/DAST platform covering multiple vulnerability classes; DOMdig does one thing and doesn't pretend otherwise.
