Whether you’re running a blog, a company website, or an internal application, web applications are often targets for malicious scans, SQL injections, and XSS attacks. Enterprise-grade WAFs (Web Application Firewalls) can be expensive, making them out of reach for individuals and small businesses. But now, there’s a free solution: SafeLine Community Edition. SafeLine offers robust web security protection without the hefty price tag—easy to use and visually appealing!
1. Overview
SafeLine is a free community version of a web application firewall (WAF) designed by Chaitin Technology, with a claim to provide protection even against 0-day attacks. It’s a great option for those who prefer not to spend on expensive security solutions. Here are some key features:
- Smart Semantic Analysis Algorithm: SafeLine is powered by an industry-leading smart semantic analysis algorithm that ensures accurate detection with low false positives, making it tough to bypass. Unlike traditional rule-based methods, SafeLine’s algorithm can handle unknown 0-day attacks efficiently.
- Nginx-Based Traffic Interception: It utilizes Nginx reverse proxy technology to intercept traffic, ensuring minimal performance impact and low business intrusion.
- User-Friendly Deployment: Deployment is a breeze with Docker—one command, and you’re good to go. This makes it extremely friendly for beginners and non-ops professionals.
- Intuitive Management Interface: Manage SafeLine through a web interface, where you can monitor the WAF’s status in real-time, review attack logs, and track site traffic metrics like PV and UV.
- Community Support: Engage with Chaitin’s technical team through Discord or submit issue on GitHub. Stay updated on the latest features and bug fixes, and enjoy a product designed with the user in mind.
- Data Statistics: View site request statistics, protection data, IP geolocation, and UV/PV information, along with access statistics from the past 30 days.
- Attack Events: Review all attack events, including the attacker’s IP (with geolocation), block counts, attack times, and durations.
-
Protection Sites: Add web sites for protection.
