How does Cloudflare WAF compare to AWS WAF?

Cloudflare WAF enforces rules at its global edge network (300+ PoPs) before traffic reaches your origin, providing better latency and larger-scale DDoS absorption. AWS WAF runs closer to your application (at ALB, CloudFront, API Gateway). Cloudflare's managed rulesets update automatically; AWS WAF managed rules require subscription selection. Cloudflare's WAF is included with Business and Enterprise plans; AWS WAF charges per rule and per million requests.

What is Fastly Signal Sciences and when is it better than AWS WAF?

Signal Sciences uses a hybrid agent+cloud model: agents run in your application environment capturing request context, sending signals to Signal Sciences' cloud for real-time analysis without blocking requests inline. This behavioral approach produces very low false positive rates compared to signature-based WAFs. It integrates with any language or framework without DNS changes. For DevOps teams frustrated by WAF false positives disrupting deployments, Signal Sciences is a popular alternative.

When should I use F5 NGINX App Protect instead of AWS WAF?

Use NGINX App Protect when deploying WAF inline in Kubernetes as an ingress controller, when you need WAF protection for microservices without routing through a cloud load balancer, or when running hybrid environments where consistent WAF policy must span on-premises and cloud workloads. AWS WAF only protects traffic through AWS managed services; NGINX App Protect protects any application stack running NGINX.
