A Web Application Firewall (WAF) is essential for modern web security. It sits at the application layer and protects your apps by filtering, monitoring, and blocking malicious HTTP/S traffic. A well-designed WAF can stop common attacks like SQL injection, XSS, and even some forms of DoS.
SafeLine: A Free and Powerful WAF
Let’s take a look at SafeLine, a robust and open-source WAF designed to secure your web traffic. Built on the reliable Nginx engine, SafeLine offers both performance and stability without compromising security.

Setting up SafeLine is straightforward. Run the following command to begin:
bash -c "$(curl -fsSLk https://waf.chaitin.com/release/latest/setup.sh)" -- --en
