Frequently Asked Questions
Are free WAFs actually effective against real attacks?
Yes. Cloudflare's free WAF blocks OWASP Top 10 attacks (SQL injection, XSS, etc.) and handles DDoS attacks automatically. ModSecurity with OWASP CRS detects hundreds of attack patterns. Our research shows CRS at Paranoia Level 1 catches the majority of common web attacks out of the box.
What is the best free WAF for Laravel?
For Laravel applications, ModSecurity with OWASP CRS on Nginx is the most common free option. It runs as an Nginx module in front of your Laravel app. Alternatively, Cloudflare's free tier works with any Laravel site by proxying DNS, no server changes needed.
What is the best free WAF for WordPress?
Cloudflare free tier is the easiest option for WordPress. For self-hosted protection, Wordfence offers a free WordPress plugin with firewall rules (delayed 30 days vs paid). ModSecurity on the server level provides stronger protection but requires server access.
What is the catch with free WAF services?
Cloud-based free tiers (Cloudflare) limit the number of custom rules and don't include advanced features like bot management or API protection. Open-source WAFs (ModSecurity, Coraza) have no feature limits but require you to manage updates, tune rules, and handle false positives yourself. There is no vendor support unless you pay.
Can I use a free WAF for a production ecommerce site?
Cloudflare's free tier is used by thousands of small ecommerce sites. For higher-stakes deployments, ModSecurity/CRS on Nginx handles production traffic at any scale (it's what many hosting providers use). However, for PCI-DSS compliance or high-value transactions, consider a paid WAF with vendor support and compliance reporting.
Final Thoughts
Cloudflare's free tier is the best free WAF for most users. Zero setup, instant protection, and it works with any website. You can't beat free + easy.
For self-hosted applications, ModSecurity + OWASP CRS remains the gold standard. It runs on Apache and Nginx, protects Laravel, WordPress, and any PHP/Python/Ruby framework, and gives you complete control over rules. If you're deploying in containers or Kubernetes, Coraza is the modern alternative with better performance.
BunkerWeb is the best option if you want a full security stack with a web UI instead of editing config files manually.
The main trade-off: cloud WAFs (Cloudflare) protect you instantly but limit customization. Open-source WAFs (ModSecurity, Coraza) give you unlimited control but require server access and maintenance. Running NGINX? See our dedicated best WAF for NGINX guide for deployment-specific advice.
