Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

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.

Quotes from Members

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

Pros

"It allows me to see all the traffic on my network."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."
"This solution can protect Layer 3, Layer 4 and Layer 7 attacks of applications for us."
"We have researched them all, and it's a good solution all around."
"Packet inspection has been effective for mitigating DDoS attacks."
"The protection resources and the support are valuable features of the solution."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"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."
"On the real time, you can see live traffic, which is flowing into our website."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"It is a stable solution."
"The solution has been quite stable. I have not seen any bugs at all."
"The solution is very good at intercepting traffic before it gets to our data centers."
"Imperva is a Gartner leader, so its scalability, performance, and features are excellent."
"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."
 

Cons

"Alerts and reporting features must be improved."
"The solution can be a little more user-friendly and it can be more affordable."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The product’s pricing needs improvement."
"I would like to see analytics, big data."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"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."
"The UI interface needs improvement."
"They can provide an option to create reports, automatically import the entire report, and create rules again. In a real-life crisis, it would be helpful to be able to import a report and generate security rules from that report. I should be able to create a simple query and import the reports automatically. It can maybe also tell us the format of the report."
"There’s nothing that’s missing in terms of features."
"We would like them to hire people in Sweden because it's quite hard when people are sitting in the UK or Belgium because some of the customers really want them to be local."
"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."
"There is nothing specific where the application firewall is falling short."
"It would be nice to have more security control over mobile applications so I would suggest adding more mobile security features. It would also be beneficial to see improvements in regards to interface bandwidth performance, CPU time, and RAM size. Learning capability of the device is quite weak."
 

Pricing and Cost Advice

"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
"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 pricing is somewhat expensive. It is actually a huge investment when compared to other countries."
"There is a license for this solution and we purchase the license annually with no additional fees."
"We are satisfied with the pricing."
"It is a very affordable solution."
"Imperva Web Application Firewall is expensive."
"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 not expensive compared to the other similar solutions in this category."
