It's well known that websites are one of the most prevalent forms on the internet today. With the rise of open-source web frameworks and various site-building tools, creating a website has become incredibly cost-effective. However, one crucial aspect often gets overlooked: website security. Many are still unfamiliar with the concept of a Web Application Firewall (WAF).
1. What is a WAF?
A WAF, or Web Application Firewall, is a security measure designed to protect your website from malicious attacks. Unlike traditional firewalls, a WAF operates at the application layer and typically functions as a web gateway, acting as a reverse proxy. It can identify and block common web attacks such as SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), server-side request forgery (SSRF), WebShell uploads, and more.
Today, I want to introduce you to a user-friendly and highly effective WAF tool: SafeLine.
2. What is SafeLine?
SafeLine is a simple, easy-to-use, and widely praised community WAF project. It’s a web gateway built on Nginx, functioning as a reverse proxy that filters out malicious traffic from hackers and protects your website from attacks.

SafeLine acts as a reverse proxy, intercepting the traffic before it hits the web server. It detects and cleanses malicious activity within the traffic, ensuring that only safe, clean traffic is forwarded to the web server.
This process effectively filters out harmful requests before they can reach your server, safeguarding your site from external attacks.
- Web Traffic Access Control
SafeLine supports configuring access control blacklists and whitelists for your site through a visual interface, allowing you to match conditions like source IP, Path, Domain, Header, and Body.
6. Key Features
Easy Installation, Simple Usage
Installation requires just a single command, and the interface is user-friendly. SafeLine offers top-tier security capabilities right out of the box, so you don’t need a deep security background to achieve excellent protection.Robust Security Capabilities
The semantic analysis-driven web attack detection algorithm is a proprietary technology created by Chaitin Tech and is highly recognized in the security industry. SafeLine also features advanced protection capabilities typically found in enterprise-level products, including IP threat intelligence, dynamic rate limiting, and intelligent modeling.High Performance, High Stability
By adding attack detection capabilities on top of Nginx, SafeLine easily supports traffic loads of 10,000+ TPS. It can scale with hardware upgrades, and the attack detection introduces only minimal latency, measured in milliseconds.
With these powerful features, SafeLine WAF offers a simple yet robust solution to ensure your website is protected against a variety of cyber threats.
