When launching a website, one of the first challenges you might face isn't from your customers but from potential attacks lurking on the internet. That's why today, we're introducing SafeLine, an open-source Web Application Firewall (WAF) that has quickly become the number one choice on GitHub. SafeLine is designed to protect your website from hacker attacks, ensuring that your online presence remains secure.
What is SafeLine?
SafeLine is a free and powerful WAF designed with simplicity in mind. It uses advanced semantic engine detection technology to provide top-notch protection against common web attacks like SQL injections and cross-site scripting (XSS). Operating as a reverse proxy, SafeLine intelligently analyzes traffic, filtering out malicious activities before they can reach your web servers.
