Did you know that 30% of all traffic on the internet comes from malicious attacks? If you’ve done web development or managed a website, you’re probably familiar with terms like SQL injection, CC attacks, XSS, and WebShell. If your website logs show strange, suspicious requests, it could be a sign that hackers are already targeting your site.
Today, I’d like to recommend SafeLine, a highly regarded web protection tool in the security community. Simply put, it’s an enhanced version of Nginx with built-in security features. Developed using industry-leading semantic analysis detection technology, SafeLine acts as a reverse proxy, protecting your website from hacker attacks.
SafeLine is backed by Chaitin Technology, a company with deep expertise in web security. Since 2015, they’ve been delivering commercial WAF (Web Application Firewall) solutions. Now, they’ve released an open-source version of SafeLine, making key features like its detection algorithms, communication protocols, and plugins available to the public. Although the control panel isn’t open-sourced, this doesn’t affect its usability.
You can check out the project on GitHub: https://github.com/chaitin/safeline
Installation Experience
SafeLine offers various deployment options on its official website, with the simplest being a one-click installation:
git clone https://github.com/chaitin/SafeLine.git
cd SafeLine
bash ./release/latest/setup.sh
Once the command is executed, open your browser and visit 127.0.0.1:9443 to access the SafeLine control panel, where you can log in and start using it immediately.
Key Features from Leading Tech Companies:
- Attack Logs: View logs and statistics of hacker attacks.
- Access Control: Configure blacklists and whitelists based on IP, Host, Path, Header, and Body.
- Rate Limiting: Limit client access based on IP and session to effectively defend against CC attacks.
- Human vs Bot Verification: Detect whether a client is a human or a bot, helping to block web crawlers and automated attacks.
- Semantic Analysis Engine: An enterprise-grade detection engine with high performance, capable of 0-day protection.
Real-World Testing
How does SafeLine perform in a production environment?
To test its effectiveness, I used blazeHTTP, an attack validation tool, to launch attacks against a website protected by SafeLine.
The results were impressive: SafeLine achieved an accuracy rate of over 99%, while maintaining a processing latency of under 1 millisecond. These numbers outperform even the enterprise-level WAF solutions provided by major security vendors.
Unique Features
SafeLine, developed over a span of 10 years, is a next-generation web application firewall. Its detection engine is powered by intelligent semantic analysis, which interprets the behavioral patterns of attacks to recognize and block them effectively.
| Traditional WAF | SafeLine | |
|---|---|---|
| Ease of Use | Complex configuration, prone to errors | Simple and user-friendly, shields complex underlying security details |
| Cost | Free version is insufficient, professional version is expensive | Free community version, fully sufficient for personal sites |
| Performance | Performance degrades significantly, good results require professional hardware | Latency under 1ms, single-core TPS over 2000, no need for specialized hardware |
In Conclusion
SafeLine is a simple to use, powerful, and free WAF that you can trust for website security. As the only next-gen WAF to have been showcased at the Black Hat Arsenal, its security credentials are solid.
