Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Developers and small security teams hunting XSS in web applications need XSSCon because it cuts through setup overhead; you run it, it finds reflected and stored XSS fast, no licensing friction. At 222 GitHub stars with consistent recent commits, the tool has proven reliable enough for teams that don't need fancy reporting or integration workflows. Skip this if your buyer is looking for a commercial vendor with SLA guarantees or needs DAST capabilities beyond XSS detection; XSSCon deliberately stays narrow.
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.
