Fast time to deploy and integrates well into the Azure ecosystem, but is expensive
I use the solution as an internal dashboard app for internal customers. We use its different automation features.  We mainly implemented it since it was easy to use and deploy. I was new to Azure and we had to deploy something quickly. The automation gives us a quick turnaround.  The time to…

I like the content monitoring feature which I haven't seen in other WAF solutions.
They could improve by minimizing false positive results. Although this occurs less with Imperva, we would like to see some further improvements. We have been using this product for last 1 years, it's result is very impressive. But due to the excessive load on the Web site where thousands of requests‎ are generated from legitimate users, however the request in which any sequential or specialised characters are requested would be directly blocked by impreva . Currently imperva blocks the special character request generated from the user, as I conduct a test where I am parsing the encoded html values of the same special characters to the input field, imperva bypasses these encoded values for example : ' i.e. %27 or / i.e %2F, the WAF bypasses these encoded characters. I hope that this device should have a capability to detect the pattern which is associated with Xss or Xsrf, rather then by not blocking the request which contains any special characters.

Pricing and Cost Advice

"The price is for this solution is fair and there is a license needed."
"We have an enterprise agreement with Microsoft and the pricing is good."
"The price of the solution depends on your architecture and how you manage it. You can control the cost in Azure quite well. The costs do not directly correlate to expenses in the features we are using."
"Azure WAF has price advantages over other WAF solutions. The pricing model is flexible because you pay on a scale based on the level of protection you need."
"I give the pricing a nine out of ten."
"There is a license or subscription renewal that our customers pay."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a five out of ten."
"The cost is somewhere around $10,000 a site. For every site, you pay individually. For every DNS entry, you have you pay."
"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"We are satisfied with the pricing."
