Hype or High Performance? SafeLine WAF Faces a Real-World Test

SafeLine isn’t just an open-source WAF—it’s a full defense engine. This guide walks you through how to deploy, test, and benchmark SafeLine in real environments.

⚙️ Fast Deployment in 5 Minutes

1. One-Click Installation (Linux)

bash -c "$(curl -fsSLk https://waf-ce.chaitin.cn/release/latest/setup.sh)"

Access the panel via https://<your-ip>:9443, and complete the quick 2FA setup.

2. Enable Dynamic Defense

• Add your application: domain, upstream port, and IP
• Enable dynamic defense for selected routes (HTML/static content)
• Visit the site once to trigger encryption rule collection (max 500 paths)
• Confirm it’s working: check obfuscated JS in browser console

🔬 Real-World Testing Tools

1. BlazeHTTP Payload Testing

BlazeHTTP is a SafeLine-integrated testing tool supporting 30,000+ attack payloads. Use it to test SQLi, XSS, RCE, and more.

Tips for accurate results:

• Temporarily disable dynamic defense & human verification
• Use QPS < 30 to avoid rate limiting
• Set log level to debug for full traceability

In testing, SafeLine blocked 92.5% of mixed attack payloads from BlazeHTTP.

2. Yakit Pentest Plugins

Simulate actual vulnerabilities using Yakit's built-in plugins, including:

• ThinkPHP RCE
• Office Automation (OA) exploits
• Database fuzzing

Results: SafeLine blocks and logs all attempts, capturing source IP and suggesting remediation.

3. Integration with Nginx/OpenResty: High Availability Architecture

SafeLine is built on top of Nginx and can seamlessly replace your existing reverse proxy layer.

For example, in an OpenResty-based cluster, you can deploy SafeLine as part of a high availability architecture. By using dynamic traffic routing, suspicious requests can be directed to the WAF for inspection, while legitimate traffic is forwarded directly to backend services — achieving both strong security and optimal performance.

🌟 Key Advantages

• Free and Open Source: SafeLine supports core features like dynamic protection and CAPTCHA-based verification, with no limits on the number of protected sites.
• Low Resource Usage: A single-core CPU can handle over 2000 TPS, making it ideal for small to medium-sized applications.
• User-Friendly: The graphical interface allows for one-click policy configuration, eliminating the need for security expertise.

SafeLine redefines the boundaries of proactive defense through dynamic protection — moving beyond passive blocking to techniques like dynamic obfuscation, semantic analysis, and environmental verification. These mechanisms leave attackers with no obvious entry points.

✅ Bottom Line

• Easy to deploy
• Battle-tested against 0days and massive payload sets
• Lightweight and blazing fast

Whether you’re defending a side project or a production API, SafeLine gives you enterprise-grade security without the enterprise cost.

Try it, test it, break it—SafeLine’s here to hold the line.
