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.

I've built integrations for different systems, and some specific integrations might not be built in yet. This might be an issue for large customers but is not a major concern overall. So, the integration part could be a bit extended. Every organization has different systems, but Salt integrates with 90% of them. If a custom integration is needed, they can build it. They're very good at integrations. So, Salt Security can provide a proof of concept with system integration and share results within two weeks, which often leads to customer purchases. At this point, the product covers everything needed. They keep adding new features, and my local customers haven't requested any missing functionality. The product roadmap is good for the market.

Quotes from Members

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

Pros

"The WAF itself has been very valuable to me because it has such a complete range of features. Another reason why I like it is because it also takes care of the total overview of the traffic over the network."
"The technical support is excellent."
"If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."
"The solution has a very good interface."
"The tool's profiling feature maps all the web application directories and related components on the profile directory. It has improved the security of my client's website applications."
"One good thing about Imperva Web Application Firewall is it can be on the cloud and also it can be on-premise."
"Data masking is the most valuable feature of this solution."
"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."
"It's really great. I would rate the stability a nine out of ten. I haven't encountered any instability issues."
 

Cons

"Imperva Web Application Firewall can improve by providing better features, such as improved prevention of zero-day attacks. Additionally, it should include a VR meta-analysis."
"Certificate management could be improved."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"Imperva Web Application Firewall could improve the API integration. It was complex for us. Additionally, The onboarding could be better."
"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."
"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."
"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."
"Imperva DDoS does not provide version control."
"The integration part could be a bit extended."
 

Pricing and Cost Advice

"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 not expensive compared to the other similar solutions in this category."
"Make sure you understand the way that Imperva charges. It's very affordable. However, I would like to see a package with the Virtual Patching included. You get to do patching separately."
"There is a license for this solution and we purchase the license annually with no additional fees."
"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 is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"Pricing could be more competitive."
"The solution's price is high for small companies."
