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.
Security teams doing bulk URL reconnaissance or rapid XSS triage will appreciate extended-xss-search because it tests multiple XSS payloads per URL instead of stopping at the first match, catching bypasses that simpler finders miss. It's free and sits on 187 GitHub stars, meaning you can deploy it in a scanning pipeline without vendor lock-in or licensing overhead. Skip this if you need interactive exploitation or DAST integration with your WAF; extended-xss-search is a scanner for finding the vulnerability, not managing remediation workflows.
