Overall, our experience with Imperva WAF has been very positive. Imperva WAF delivers strong value and has met our expectations from both a usability and security standpoint.

Since the Thales acquisition of Imperva, customer support and interaction has been absolutely phenomenal. The team at Thales is very proactive with helping to ensure the customer is aware of what features are available, troubleshooting issues, and making the customer feel as though they've been heard. That said, the product itself could be considered a little lacking. New features appear to be released with the notion of a goal and perhaps some client direction, but without seeing the vision to a full conclusion prior to being released. While meetings with product managers are helpful, it does appear like the path is set and the meetings are less about listening and understanding needs and more about instructing as to the new features' capabilities. Similarly, pre-existing products suffer from user interface flaws and an almost black box approach to logic - knowledge of how the product works that seems to have been lost in the transition to Thales.
