Fastly API Security is a commercial api security tool by Fastly. F5 WAF for NGINX and F5 DoS for NGINX is a commercial api security tool by F5. Compare features, ratings, integrations, and community reviews side by side to find the best api security 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:
Teams managing APIs at scale across multiple regions need Fastly API Security because it discovers and protects undocumented APIs in real time at the edge, catching shadow APIs before they become breach vectors. The platform covers all six OWASP Top 10 API risks and integrates DDoS and bot mitigation without requiring separate tools, reducing alert fatigue from fragmented stacks. Skip this if you're looking for API governance and compliance workflow automation; Fastly excels at runtime detection and threat response, not policy enforcement or change management.
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.
