AWS Web Application Firewalls (WAFs) is a free cloud web application and api protection tool. F5 Distributed Cloud WAF is a commercial cloud web application and api protection tool by F5. Compare features, ratings, integrations, and community reviews side by side to find the best cloud web application and api protection fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams already deep in AWS infrastructure will move fastest with AWS WAF because it threads directly into API Gateway, CloudFront, and ALB without separate agent deployment or data exfiltration concerns. The free tier eliminates budget friction for prototype and mid-tier workloads, and native CloudWatch integration means you're not bolting on a separate SIEM. Skip this if your web applications sit outside AWS or you need API schema validation and runtime threat detection; AWS WAF does request filtering well but doesn't understand your API's legitimate behavior the way specialized API security tools do.
Mid-market and enterprise teams protecting APIs across multi-cloud infrastructure will get the most from F5 Distributed Cloud WAF because its behavior-based threat detection and automatic signature tuning actually catch zero-day variants without requiring constant manual rule updates. The tool's Layer 7 DDoS protection and bot detection work across AWS, Azure, and GCP simultaneously, which matters when your applications aren't sitting in a single cloud. Skip this if your environment is entirely on-premises or if you need the WAF tightly integrated with your SIEM; F5 prioritizes continuous monitoring and detection over incident response automation.
