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.

Offers Application Protection Against Web Attacks
There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

Quotes from Members

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

Pros

"Simplifies putting everything in code."
"The most valuable features of the Imperva Web Application Firewall are performance and flexibility. We can extend or customize the box itself."
"Imperva DDoS is fairly stable, and its availability is quite high."
"Imperva WAF's strongest features are the detection of web application threats and vulnerabilities in the source code."
"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."
"The solution is cloud-based and offers us good uptime. It has combined web and API security. Therefore, with one license, you access both application security and also API security."
"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."
"It works right out of the box once you integrate the application."
"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."
 

Cons

"We had an issue when securing the web applications for DDoS protection."
"Sometimes our web application firewall will slow down."
"Imperva Web Application Firewall is a good system, but we found that the visibility of the diverse-path server, e.g. where the traffic is coming from, the different IPs, etc., needs improvement."
"The tool's UI is complicated. It would be best to have a more accessible UI dashboard to make the job easier."
"The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side."
"I am looking for more data enrichment. We should have the ability to add our own custom data to the system, to the live traffic."
"The solution should integrate with something that looks at continuous security management."
"There could be some limitations that from the converged infrastructure perspective: when you want to converge with everything and you want Imperva to get there easily because it's not a cloud component. For example, when you want to build servers and you're using OneView to manage your software-defined networks, implementing Imperva right away is not that simple. But if you're doing just a simple cloud infrastructure with servers in there, you're good to go. Also, we are not able, with Imperva, to block by signatures. Imperva by itself needs to be complemented with another service to do URL filtering."
"There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly."
 

Pricing and Cost Advice

"The price of Imperva Web Application Firewalls is expensive compared to others."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"There is a license or subscription renewal that our customers pay."
"The cost of this solution depends on the platform."
"The price is high compared to other solutions like FortiWeb."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"It is a very affordable solution."
"It is expensive."
