SafeLine is a self-hosted Web Application Firewall (WAF) and reverse proxy that sits in front of your web applications to detect and block common attacks like SQL injection, cross-site scripting (XSS), brute force attempts, and HTTP floods. Developers use it to add a security layer without relying on third-party cloud services, giving them direct control over their application's attack surface and security policies. It functions as both a reverse proxy and API gateway, allowing you to inspect and filter traffic before it reaches your backend services.
