Application Gateway vs F5 WAF for NGINX and F5 DoS for NGINX: Side-by-Side Comparison (2026)

Application Gateway

Teams running multi-region cloud applications on Azure will get the most from Application Gateway because its native integration with Azure infrastructure eliminates the latency and complexity of bolted-on WAF solutions. It handles Layer 7 load balancing with built-in DDoS protection across Microsoft's global backbone, and the free tier removes budget friction for teams testing WAF capabilities before scaling. Skip this if you need a vendor-agnostic WAF that ports easily to AWS or GCP; Application Gateway is tightly coupled to Azure and doesn't play well outside that ecosystem.

F5 WAF for NGINX and F5 DoS for NGINX

DevOps teams running NGINX in Kubernetes will get the most from F5 WAF for NGINX and F5 DoS for NGINX because the declarative, API-driven configuration model actually fits how modern infrastructure teams work instead of fighting them. The eBPF-based multi-layer defense and 7,500+ attack signatures cover OWASP Top 10 API risks across REST, GraphQL, and gRPC without requiring signature tuning for every new endpoint. Skip this if you need centralized visibility across multiple WAF vendors or run primarily on cloud-managed API gateways; F5's strength here is depth in the NGINX ecosystem, not breadth across platforms.
