CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Security teams running reconnaissance workflows or building custom crawling pipelines will get the most from Katana; the 14K GitHub stars reflect genuine adoption by practitioners who need fine-grained control over spidering logic rather than point-and-click scanners. The framework approach means you're writing code to extract what matters to your target scope, which beats generic crawlers for complex authentication flows or JavaScript-heavy applications. Skip this if your team lacks engineering resources or needs a managed SaaS interface; Katana requires Python knowledge and infrastructure to operationalize.
