Cloudflare WAF
Pros
- + WAF engine and managed ruleset included on every plan, including Free
- + Unmetered DDoS absorption at the edge on all tiers
- + Central rules maintenance — no appliances, agents or rule deployments to manage
- + Attack-score and bot-management layers available as needs grow
- + Flat plan pricing; no per-request or per-rule metering
Cons
- - Advanced rate limiting, attack-score rules and full log export are plan-gated
- - Managed rules can block legitimate traffic; tuning requires a logging-first workflow
- - Free plan limits request body inspection to 1 MB
- - Only applies to proxied records — DNS-only traffic is not filtered
- - A compensating control, not a substitute for fixing application vulnerabilities
AWS WAF
Pros
- + Edge-level blocking on CloudFront stops bad traffic before it reaches the origin
- + Transparent metered pricing with AWS's own worked cost examples published
- + AWS managed rule groups (OWASP CRS, SQLi, IP reputation) cost $1 each per month
- + Written SLA: 99.95% monthly uptime per region with defined service credits
- + Full API/CloudFormation coverage and deep CloudWatch and logging integration
Cons
- - Useless outside AWS — only protects CloudFront, ALB, API Gateway and AppSync resources
- - Web ACL Capacity Unit overages and Bot Control per-request fees can multiply the bill
- - Rule authoring is verbose JSON; serious use needs AWS and infrastructure-as-code skills
- - No free tier and no bundled DDoS cost protection without the separate Shield Advanced subscription
