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…

Application protection has improved and reporting and dashboards still need refinement
I believe Imperva Application Security Platform should have a more interactive wizard. While the dashboard is good, it could be more eye-catching. Based on my perspective, I recommend modifying the dashboards, especially the main dashboard where I can see the traffic hit count, alerts, and other latest information. In terms of reporting, I find it challenging to create reports; in my earlier days, it was difficult. Over time, I have learned how to create reports, but it should be easier to do so. I have used other tools such as firewalls or SolarWinds, where creating a report is straightforward and does not take much time, unlike in Imperva, where I have to add many elements. Modifications in the integration aspects would also be beneficial.

Quotes from Members

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

Pros

"The pricing of this solution is better than that of Cisco and other software on the market, which are very expensive."
"We've been completely satisfied with the product."
"The solution is very user-friendly and very easy to use."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"The product allows the users to adjust the thresholds."
"We have researched them all, and it's a good solution all around."
"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."
"Packet inspection has been effective for mitigating DDoS attacks."
"The features that are most valuable are the protection against denial-of-service attacks and all kinds of other internet attacks."
"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 offers good security against a variety of web attacks, and the protection from DDoS attacks is very useful."
"It is easy to use and has good security."
"It's very pretty easy to onboard the URL."
"Based on my experience, and what I know this product can do, I would never recommend another solution."
"It is a stable solution."
"Great product, it will not let you down!"
 

Cons

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"Alerts and reporting features must be improved."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"The product’s pricing needs improvement."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The initial setup is complex. It is always complex."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The solution can be a little more user-friendly and it can be more affordable."
"Imperva Web Application Firewall is very expensive."
"One thing that they really could improve on is the depth of the analytics."
"Improve reporting interface and filtering."
"One improvement I would like to see in Imperva Application Security Platform is the ability to fail over to different sites for my same application."
"The tool needs to include artificial intelligence and machine learning. It also needs to improve profiling."
"Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers."
"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."
"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."
 

Pricing and Cost Advice

"It's quite pricey."
"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It is expensive."
"Imperva Web Application Firewall is expensive."
"We are satisfied with the pricing."
"It is a very affordable solution."
"Everybody complains about the price of this solution."
"​Although the pricing can be a little high, it is worth the protection and security that it offers.​"
"The license is on a yearly basis."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
