The Best Web Application Firewalls

Best Web Application Firewalls

Diego Asturias UPDATED: April 9, 2024

A Web Application Firewall (WAF) is a security system that aims to protect web apps and sites, using a set of rules that filter HTTP traffic. It monitors and blocks any malicious or abnormal behaviors coming from the Internet and going towards web apps.

A Web Application Firewalls (WAF) software solution should be capable of dealing with OWASP’s top ten. Some of these common web attacks include: 

  • SQL injections.
  • Cross-site forgery.
  • DDoS attacks,
  • Cross-Site Scripting (XSS).
  • and other types of attacks.

Still, web apps are vulnerable to zero-day attacks or might have unique traffic patterns, so a WAF must look beyond the common web attacks.

More advanced WAF solutions can provide automated defenses and managed services to control these sets of rules. These advanced WAF solutions give access to expert security teams, edge networks, threat intelligence, AI/ML analytics, traffic monitoring, and more.

In this post, we’ll go through the best WAF vendors that provide the most comprehensive web app security:

  1. Sucuri Website Firewall. A cloud-based WAF with a large database of attack signatures developed by Sucuri’s expert research.
  2. Imperva Cloud WAF. A component of an integrated defense suite, including CDN, DDoS mitigation, bot protection, and more.
  3. Barracuda Web Application Firewall. It uses positive signature-based rules and robust analysis/detection capabilities to defend your assets.
  4. AppTrana Managed Web Application Firewall A fully-managed WAF designed to automatically scan, find vulnerabilities, and patch applications. AppTrana is bundled with a CDN and managed security rules.
  5. AWS WAF. A cloud-based WAF that leverages other AWS services to detect and mitigate web attacks.
  6. F5 Advanced WAF. It uses a combination of threat intelligence and ML to protect web apps from data breaches, zero-day, and OWASP’s top ten risks.
  7. Cloudflare WAF. A cloud-based WAF that leverages a massive CDN, provides automatic protection from app’s vulnerabilities and allows customized rules.
  8. Akamai Kona Site Defender.  Built on Akamai Intelligent Edge Platform and designed to protect web apps, sites, and API from OWASP’s top ten, L7 DDoS, and zero-day attacks.
  9. Radware Cloud WAF. A cloud-based WAF capable of responding against the most sophisticated and damaging web threats.
