I tried SafeLine WAF while building a hardened reverse proxy setup for a set of internal admin dashboards. What stood out first was how fast and easy the initial deployment was — it didn’t take more than 15 minutes to get a basic setup running with traffic flowing through it. The built-in engine did a decent job blocking scan attempts and common payloads, and I liked the fact that it logs clearly what got blocked and why. One drawback of SafeLine is that it currently doesn’t support DNS challenge, which can be inconvenient in some scenarios. But it’s still a promising project. It’s rare to find a free WAF that feels this modern and still gets regular updates. It’s a strong alternative to ModSecurity — especially if you care about visibility and want something lighter and more streamlined.
