SafeLine

SafeLine is a self-hosted Web Application Firewall (WAF) built to defend modern web applications against a wide range of cyber threats—including zero-day attacks. Unlike traditional cloud-based WAFs, SafeLine runs entirely on the own infrastructure, giving users full control over traffic, data, and security policies.

At the core of SafeLine is a patented semantic analysis engine that deeply understands HTTP request intent rather than relying solely on signatures. This enables high-accuracy detection of sophisticated attacks while maintaining an exceptionally low false positive rate—making it ideal for production environments.

SafeLine is fast to deploy and easy to configure. With just one command, it can be up and running on any Docker-supported Linux system. A user-friendly, wizard-based interface makes setup and policy tuning straightforward, even for teams without deep security expertise.

SafeLine comes packed with powerful features such as advanced bot protection, rate limiting, waiting rooms for DDoS mitigation, and identity-based access control—with many of these enterprise-grade capabilities available for free.
