With the increasing popularity of open-source frameworks and site-building tools, creating a website has never been easier. However, one critical aspect that many overlook is website security, particularly the use of a Web Application Firewall (WAF) to protect against cyber threats.

What Is WAF?

A Web Application Firewall (WAF) acts as a shield for your website, protecting it from malicious attacks that target your application layer. Unlike traditional firewalls, which focus on network traffic, a WAF specifically filters and monitors HTTP requests, blocking common threats like SQL injections, cross-site scripting (XSS), and other vulnerabilities.

Meet SafeLine

SafeLine is an open-source WAF developed by Chaitin Technology, designed for simplicity and effectiveness. It's an excellent choice for those who want robust web security without the steep learning curve or high costs associated with commercial WAF solutions. SafeLine is built on Nginx and functions as a reverse proxy, filtering out harmful traffic before it reaches your web server.

Installing and Deploying SafeLine

SafeLine is deployed using Docker containers, making installation straightforward and manageable. The developers provide an installation script that handles everything, from pulling necessary images to configuring files and launching the service.

To get started, clone the SafeLine repository and run the setup script:

git clone https://github.com/chaitin/safeline.git
cd safeline
bash ./setup.sh

Alternatively, you can use the online installation script:

bash -c "$(curl -fsSL https://waf.chaitin.com/release/latest/setup.sh)"

Once installed, you can access SafeLine through your local web server and start configuring it to secure your site.

How SafeLine Works

SafeLine acts as a reverse proxy, sitting between the user and your web server. When a user attempts to access your site, SafeLine inspects the incoming traffic for potential threats. If any malicious activity is detected, SafeLine filters it out, ensuring that only clean, safe traffic reaches your server.

Why Choose SafeLine?

• Easy to Use: Installation and setup are simple, even for beginners. SafeLine offers high-level security without requiring deep technical knowledge.
• Powerful Security Features: Built with Chaitin Technology’s proprietary algorithms, SafeLine delivers enterprise-grade security.
