CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
DevOps teams running nginx at scale who want injection attack prevention without vendor lock-in should start with NAXSI; it's free, battle-tested across 4,800+ GitHub deployments, and sits directly in your request path where it blocks XSS and SQL injection before they reach your application. The tradeoff is real: NAXSI is a passive filter, not an active threat hunter, so you're prioritizing prevention over detection and forensics. Not for buyers who need centralized attack visibility across multiple web servers or API gateways; this is a single-engine protection layer that requires manual rule tuning.
