The solution automatically scales according to traffic, only takes minutes to deploy, and is maintenance-free
The primary use case of the solution is firewall protection. Having a firewall is important for protecting our website from DDoS attacks. Just in case our services are running and we do get attacked, having a firewall can help keep our website alive The solution gives us a better sense of…

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:


"I am impressed with the product's multiple features like security."
"The product is easy to use."
"It is integrated with AWS. So, it gives you a good first step."
"The product has a good mechanism to analyze trends and trigger events."
"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."
"The solution's ease of use is the most valuable feature."
"The solution's most valuable aspect is that it is easy to configure."
"​Technical support provides good, quick responses."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user."
"It fits our requirements, as well as our budget."
"The setup of Imperva DDoS was easy."
"Scalability is pretty easy on the base platform. You just add another, and you're ready to go."
"The most valuable features for us are the DDoS and Bot."


"The product needs to improve its logs and reports to make it read better."
"The product is expensive."
"We end up having to pay extra for features that AWS adds that we don't need."
"The time taken to detect anomalies must be reduced."
"The product should give users more flexibility to customize their security policies according to their requirements."
"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."
"The rules surrounding the making of web applications could be improved."
"A limited tool if you're looking to customize."
"I would like to have support for SSL management and secure DNS."
"The solution needs to improve Integration with third parties for their on-prem deployment models. The integration is not that good yet."
"Its price could be improved. It is quite expensive. It will be good if we could export the configuration. Currently, to control the configuration, we need to go to each website, which is not very convenient."
"Imperva should have more points of presence in Africa."
"There’s nothing that’s missing in terms of features."
"I miss being able to integrate the dashboard with other BI tools we are using. We have to export and import data to be able to present it, and doing so is a lot of work."

Pricing and Cost Advice

"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."
"The tool's pricing is good."
"We pay $3000 per month for the solution."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"The tool is cheap."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"We are satisfied with the pricing."
"It is not expensive compared to the other similar solutions in this category."
"Pricing could be more competitive."
"The license is on a yearly basis."
"Varies depending on the needs of the customer."
"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."
