The ease to set up rules, the fact that it's customizable, and easy integration with other products from Signal is really great! I do not have any complaints about this product at all. It works very well as intended. There are no security loopholes or issues that I can see right now. If you're looking for an effective WAF solution, then look no further than Signal. Their support team has been nothing but helpful when we've had questions or concerns. They make sure things get fixed quickly without us having to chase them down too much.
