Did you know that over 30% of internet traffic is malicious? If you manage a website or write backend code, you’ve likely seen weird traffic: SQL injections, XSS payloads, WebShell attempts, or CC attacks flooding your logs. That’s not just noise—it’s someone trying to break in.
🚀 What Is SafeLine?
SafeLine is an open-source Web Application Firewall (WAF) developed by the security experts at Chaitin Tech. Think of it as an upgraded version of Nginx—with built-in enterprise-grade protection.
It works as a reverse proxy, sitting between the internet and your web app, intelligently blocking attacks in real time using advanced semantic analysis instead of brittle regex rules.
Unlike traditional WAFs that rely on fixed rules or pattern matching, SafeLine understands the meaning of code and payloads—just like DNA analysis sees through superficial disguises.
🛠️ Simple Installation
Clone and run with one command:
git clone https://github.com/chaitin/SafeLine.git
cd SafeLine
bash ./release/latest/setup.sh
Then open your browser at 127.0.0.1:9443 to access the web UI and start configuring your protections.
🧠 Why SafeLine Is Different
- Semantic Analysis Engine: Detects malicious behavior, not just strings.
- Zero-Day Protection: Blocks unknown attacks by understanding code intent.
- Bot Defense: Blocks scrapers and automated scanners.
- Access Control: Blacklists, whitelists, headers, and rate limiting.
- Real-Time Logs: Watch attacks unfold in your dashboard.
📈 Real-World Performance
Using blazeHTTP（an attack validation tool） to simulate real attacks, SafeLine achieved:
- ✅ 99%+ detection accuracy
- ⚡ <1ms processing latency
That's on par with—or better than—many commercial WAFs.
🧩 Why Developers Love It
| Feature | Traditional WAF | SafeLine |
|---|---|---|
| Setup & Config | Complex & fragile | Easy, intuitive |
| Performance | Hardware-dependent | Fast even on single-core |
| Licensing | Expensive paid tiers | Free & open source |
| Detection Method | Regex & rules | Semantic analysis engine |
🔒 Backed by Security Pros
Chaitin Tech has been building commercial WAFs since 2015. SafeLine brings that experience to the open-source world. While the control panel remains closed-source, everything else—detection engine, plugin system, protocols—is available for inspection and use.
