🌐 Website Firewall Comparison

What a WAF Does (and Does Not Do)

A Web Application Firewall sits between your website and the internet, inspecting every request for malicious patterns. It blocks SQL injection attempts, cross-site scripting (XSS), bad bots, DDoS attacks, and brute-force login attempts before they reach your server. A WAF does NOT replace: keeping your CMS and plugins updated, using strong passwords, regular backups, or SSL certificates. It is one layer in your defense — but arguably the most important one for websites.

Detailed Reviews

1. Cloudflare — Best Free WAF for Any Website

Cloudflare's free plan includes a basic WAF with managed rulesets that protect against the OWASP Top 10 (SQLi, XSS, command injection, etc.), DDoS protection (unmetered!), SSL, CDN, and bot management. For most small business websites, the free plan provides substantial protection with 5-minute setup (change your DNS nameservers to Cloudflare). The Pro plan ($20/month) adds an advanced WAF with custom rules, image optimization, and prioritized support. If you do one thing for your website security today, put it behind Cloudflare.

2. Wordfence — Best WordPress Endpoint Firewall

Wordfence is a WordPress plugin that provides both a firewall and malware scanner. Unlike Cloudflare (which is a cloud-based WAF), Wordfence runs on your server — meaning it can see requests after they pass through SSL decryption and understand WordPress-specific attack patterns. The free version includes a firewall with a 30-day delayed ruleset; Premium ($119/year) gives real-time rules, country blocking, and premium support. Wordfence + Cloudflare is a powerful combination: Cloudflare blocks attacks at the edge, Wordfence catches what gets through.

3. Sucuri — Best Managed Security Platform

Sucuri offers a cloud-based WAF plus managed malware cleanup and monitoring. If your site gets hacked, Sucuri's team cleans it — included in the $199/year Platform plan. The WAF blocks attacks, the monitoring alerts you to changes, and the cleanup service gives you a safety net. For business owners who want "someone else handles it" and are willing to pay for that peace of mind, Sucuri is the best choice. The main downside: no free tier, and $199/year is significantly more than Cloudflare (free) + Wordfence (free).

4. SiteGround Security — Best for SiteGround Users

If your site is hosted on SiteGround, their free SiteGround Security plugin provides a solid WAF, login protection, and hardening features out of the box. It is not as feature-rich as Wordfence, but it is optimized for SiteGround's infrastructure and causes zero performance overhead. Use it alongside Cloudflare for defense in depth.

5. MalCare — Best One-Click Malware Removal

MalCare differentiates with its one-click malware removal — if malware is detected, you click one button and MalCare's servers clean your site. No manual file editing or developer required. The Basic plan at $99/year covers one site with firewall + scanner + one-click cleanup. The firewall is less sophisticated than Cloudflare or Wordfence, but the cleanup capability makes it worth considering for business owners who want a safety net without the cost of Sucuri.
