If you've ever set up your own website, you know how vulnerable it can be to attacks. Today, I'm introducing a simple, free, and effective tool to help protect your site—a Web Application Firewall (WAF) called SafeLine.
What is a WAF?
WAF stands for Web Application Firewall. Unlike traditional firewalls, WAF operates at the application layer, offering enhanced protection for web systems that run on HTTP/HTTPS protocols. This makes it an essential tool in shielding your site from malicious attacks.
What is SafeLine?
SafeLine is a robust, easy-to-use, and completely free WAF designed to protect your website from hackers. It uses cutting-edge semantic detection technology and functions as a reverse proxy, ensuring that your site stays safe.
