Features, pricing, ratings, and pros & cons — compared head-to-head.
http-sniffer is a free security scanning tool. Intruder XSS Scanner is a commercial security scanning tool by Intruder. Compare features, ratings, integrations, and community reviews side by side to find the best security scanning fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams running packet-level incident response on internal networks will get immediate value from http-sniffer because it surfaces HTTP headers from live traffic without the overhead of full packet capture tools. The multi-threading architecture and JSON output make it faster to parse than tcpdump for header-focused investigations, and the 193 GitHub stars suggest active use in detection workflows. Skip this if you need encrypted traffic visibility or HTTPS inspection; http-sniffer sees only cleartext HTTP, which limits its usefulness in modern environments where most internal services run over TLS.
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.
