When it comes to protecting modern web apps, a traditional firewall isnāt enough. You need a Web Application Firewall (WAF)āa tool that works at the application layer to filter, monitor, and block HTTP(S) traffic, defending against threats like SQL injection, XSS, and zero-days.
But choosing the right WAF isnāt easyāespecially when balancing security, ease of use, and performance. Thatās where SafeLine shines.
Why SafeLine Deserves Your Attention
SafeLine is a high-performance WAF developed by Chaitin Tech, built on nearly a decade of experience in security. It uses an intelligent semantic analysis detection engineānot legacy rule-based filtersāto catch both known and unknown threats with impressive accuracy.
What really sets SafeLine apart is that it offers enterprise-grade protection for free. While the commercial edition powers large enterprises, the freely available version uses the same intelligent detection engine.
