In the crowded world of web application firewalls (WAFs), finding a solution that balances strong security, flexibility, and cost-effectiveness is not easy — especially for startups, homelabs, and small teams.
That’s where SafeLine WAF stands out.
What Makes SafeLine Different?
Unlike traditional WAFs that rely solely on pattern matching or signature-based detection, SafeLine is powered by a semantic analysis engine — a powerful mechanism that understands the intent and context of HTTP requests.
The result? Exceptionally low false positive rates and accurate attack detection that work in real-world environments.
And the best part? This same cutting-edge engine is available even in the free version.
Enterprise-Level Protection, Self-Hosted
SafeLine is self-hosted, giving you full control over your infrastructure and data. It requires no registration, no license server, and no vendor lock-in. Just install it with Docker, configure a few rules, and start protecting your applications in minutes.
