Cloudflare WAF review
Broad edge WAF coverage with a free plan and Terraform management.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Cloudflare WAF is a cloud-delivered web application firewall for websites and APIs. It inspects HTTP and HTTPS requests at Cloudflare’s edge, applying managed rulesets, custom rules, and protections for attacks such as SQL injection and cross-site scripting. Cloudflare positions it for personal projects, professional websites, small businesses, and mission-critical enterprise applications.
Pricing spans Free, Pro, Business, and Contract plans. The Free plan costs $0 per month with monthly billing and includes WAF, a Free Managed Ruleset, and one rate-limiting rule. Pro costs $20 per month with annual billing or $25 per month with monthly billing, adding WAF Managed Rules and rate-limiting rules. Business costs $200 per month with annual billing or $250 per month with monthly billing, with WAF Managed Rules and rate-limiting rules. The Contract plan includes WAF and enterprise application security features. Cloudflare notes that pricing may vary by region or contract.
The product’s feature set covers managed rulesets with regularly updated protections, custom request-property and expression rules, OWASP Top 10 protection, virtual patching for announced CVEs, API request protection, configurable rate limiting, Security Events, and Security Analytics. API and Terraform management support platform integration, while the edge deployment model suits teams that want inspection before traffic reaches applications. Teams seeking broad web and API coverage, automated rule updates, and a free starting point should consider Cloudflare WAF. Organizations that require bot management as a standard WAF capability should evaluate alternatives or Cloudflare’s separate Bot Management product.
