Do You Have a Website? Are You Worried About Hackers Attacking It?

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
Enter fullscreen mode Exit fullscreen mode

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.
