 Automated tools like **SQLMap** will receive a different randomized database error on each request, increasing scan noise and confusing the attacker. All detected attacks are logged and displayed in the dashboard.
 
+## Example usage behind reverse proxy
+
+You can configure a reverse proxy so all web requests land on the Krawl page by default, and hide your real content behind a secret hidden url. For example:
+
+```bash
+location / {
+    proxy_pass https://your-krawl-instance;
+    proxy_pass_header Server;
+}
+
+location /my-hidden-service {
+    proxy_pass https://my-hidden-service;
+    proxy_pass_header Server;
+}
+```
+
+Alternatively, you can create a bunch of different "interesting" looking domains. For example:
+
+- admin.example.com
+- portal.example.com
+- sso.example.com
+- login.example.com
+- ...
+
+Additionally, you may configure your reverse proxy to forward all non-existing subdomains (e.g. nonexistent.example.com) to one of these domains so that any crawlers that are guessing domains at random will automatically end up at your Krawl instance.
