Six rules deep.Still denied.

In front

Imperva sits in front of the origin.

It's a reverse proxy. Nothing reaches the server until the rulebook clears. Hover the WAF to see the layers it stacks.

Every rule passes

One call clears the whole rulebook.

Point Fetch at an Imperva-protected site. Real fingerprint, human behavior, trusted network: every rule returns pass, and the origin responds.
