SafeLine

An open-source, self-hosted web application firewall that protects your apps.

About SafeLine

SafeLine is a web application firewall and reverse proxy from Chaitin Tech, now CyberServal, that protects web applications from attacks and exploits. Its machine-learning semantic analysis engine detects web threats, bot attacks and HTTP flood DDoS attempts, with identity and access management on top. The free Personal edition covers up to ten apps forever, while paid Lite and Pro tiers raise limits — a fit for site owners wanting enterprise-grade WAF protection they can self-host.
