CST VerdictBased on our analysis of available product data, here is our conclusion:
Teams protecting APIs at the edge will find value in Curiefense's tight integration with Envoy proxy, which catches SQL injection and XSS before they reach your backend services. The free, open-source model means you can deploy it without vendor lock-in and audit the ruleset yourself, a rare advantage when evaluating WAF logic. Skip this if you need managed threat hunting, incident response, or a vendor to call when your API gets hit; Curiefense's single GitHub star signals a small maintenance surface and limited community tooling compared to commercial alternatives.
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.
