AWS Web Application Firewalls (WAFs) is a free cloud web application and api protection tool. Cloudflare WAF is a commercial cloud web application and api protection tool by Cloudflare, Inc.. 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, company size fit, deployment model, 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.
Startups and SMBs with limited security ops capacity should pick Cloudflare WAF for its zero-trust integration with your existing DNS and CDN layers, eliminating the need for separate appliance management. The platform handles NIST PR.PS and PR.IR through managed rulesets and DDoS mitigation without requiring full-time WAF tuning; you're inheriting Cloudflare's threat intelligence across their 280+ million daily requests. Skip this if you need granular application layer control or extensive custom rule development; the managed approach trades flexibility for speed-to-protection.
