Web applications are constantly targeted by various cyberattacks like Cross-Site Scripting (XSS), SQL Injection, Distributed Denial-of-Service (DDoS), and zero-day exploits. To protect against these threats, Web Application Firewalls (WAFs) are essential. A WAF acts as a digital shield for your web application, filtering and monitoring HTTP traffic to block malicious activity before it reaches your application.
In this article, we’ll explore the top 10 free WAF solutions for 2024, including leading players like Barracuda, Cloudflare, and KEMP, as well as several open-source and community-driven alternatives.
?What is a Web Application Firewall (WAF)?
A Web Application Firewall (WAF) is a security tool that protects your web applications from common cyber threats, including SQL injection, XSS, file inclusion, and other malicious activities. Unlike traditional firewalls, which focus on network-level attacks, WAFs operate at the application layer, inspecting incoming traffic to block threats before they reach your application.
