SafeLine WAF: A Powerful, Free Web Application Firewall

SafeLine WAF Community Edition is a free, next-generation web application firewall launched by Chaitin Technology. Built on industry-leading semantic analysis detection technology, it’s designed to provide websites with a simple, user-friendly, yet powerful defense. The core strength of SafeLine WAF lies in its pioneering semantic analysis algorithm. Unlike traditional rule-based methods, this algorithm offers more precise attack detection, reduces false positives, and is much harder to bypass.

1. High-Performance Protection

When it comes to performance, SafeLine WAF Community Edition stands out. It utilizes a rule-free engine and a linear security detection algorithm, ensuring an average detection delay of less than 1 millisecond. Even with a single-core processor, it can easily handle over 2000 TPS (transactions per second). Additionally, being developed based on Nginx, SafeLine WAF includes a robust health check mechanism, ensuring high concurrency and availability.

2. Comprehensive Capabilities
