When you're building web apps, security is non-negotiable. SafeLine WAF is an open‑source Web Application Firewall (WAF) that’s easy to deploy, highly effective, and built to scale.
What Is SafeLine?
SafeLine is an intuitive WAF that monitors and filters HTTP traffic between your web server and the internet. It protects against a wide range of attacks, including:
- SQL Injection
- XSS
- Code/Command Injection
- CRLF Injection
- LDAP/XPath Injection
- RCE, XXE, SSRF
- Path Traversal, Backdoors
- Bruteforce, CC/DoS Attacks
- Crawlers and more
Licensed under GPL-3.0, it grants freedom to use, modify, and distribute, while ensuring your modifications stay open—perfect for community-driven innovation.
Key Features
1. Semantic Analysis Engine
Breaks past rule-based limitations using semantic analysis—boosting accuracy, reducing false positives, and staying tough to bypass.
2. Smart, No-fuss Security
One-click Docker-based install, plug-and-play setup—no time wasted on crafting complex rules.
3. High Performance & Scalability
Line-speed inspection with no bulky rule engine. Avg latency < 1ms; >2,000 TPS per core thanks to Nginx foundation and built-in health checks.
4. OWASP‑Aware Attack Detection
Smart engine hunts OWASP risks without relying solely on static rules—analyzing HTTP/HTTPS behavior in real time.
