Solution ensures website availability and proactive threat mitigation
Over the seven years, the most valuable features of Imperva DDoS that I have found are related to DDoS attacks, which are a group of attacks, and not all of them can be resolved on the endpoint level before the website. Using the web firewall before the website is a common use case to protect against malicious requests to the website. I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website. It allows me to granularly grant or deny access to certain parts of our website. This helps when we know our customers and the types of requests that can be sent from them, enabling us to block some malicious requests. Imperva DDoS has User Behavior Analytics and Threat Intelligence on its board, and this helps us to be protected proactively. Imperva DDoS connects to its database of threats, storing whole information about attacks all over the world in one simple engine. Everyone can use this feature, which can connect to this engine and get information about what is going on at the world level. That is the way to be protected at the company's level. The integration capabilities of Imperva DDoS are very easy and simple. We can run it in 2 hours.

Helps us to monitor attacks to our sites and prevents a lot of them
Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

Quotes from Members

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

Pros

"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."
"Its inline transferring mode is the most valuable because it is 100% transparent. When you change the IP, there is no change on the network side. If you can't and want to try to reach an IP, you can reach the server IP. There are many other advanced security features in it. The smallest appliances of Imperva can handle the highest traffic at a customer site. For example, a smaller appliance from Imperva can provide you the same security as an F5 product."
"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"The dashboard is good and user-friendly."
"Real-time monitoring is also a great tool, as you may watch several parameters in real time."
"The setup of Imperva DDoS was easy."
"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."
 

Cons

"The reporting is missing some features, such as: only two export formats, and the time period does not include the last day, week, year."
"Imperva Web Application Firewall could improve the API integration. It was complex for us. Additionally, The onboarding could be better."
"There's always room for improvement. Occasionally, there might be false-positive alerts."
"Some of the features should be included in the next release is a file integrating monitoring tool. This feature should be improved."
"It should be more user-friendly. Like other web solutions, it would be helpful to be able to easily do policy configuration and identification inside the application. Understanding the in-depth configuration of a policy is somewhat difficult for an engineer, and they can improve that."
"Sometimes, it takes a bit of time for the technical staff of the solution to get back to our company with a resolution for our problems."
"The solution should integrate with something that looks at continuous security management."
"The only disadvantage of Imperva is that it is a pretty costly solution."
"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."
 

Pricing and Cost Advice

"I rate the product price a four on a scale of one to ten, where one is a low price, and ten is a high price."
"Imperva Web Application Firewall is expensive."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"It is a very affordable solution."
"The price of this solution is a little bit high compared to competitors."
"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."
"It's an excellent product, but it can be very costly."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"​Pricing must be cheaper than the competition and the licensing must be good.​"
