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

"It is a user-friendly product in terms of monitoring and updating policies."
"I find the interface easy to use."
"The product allows the users to adjust the thresholds."
"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, and this is important."
"Packet inspection has been effective for mitigating DDoS attacks."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"​Technical support provides good, quick responses."
"Imperva Application Security Platform has positively impacted my organization by providing strong protection for web applications, as many big companies in the UK use Imperva WAF as an essential protection layer, illustrating its effectiveness."
"We are using Incapsula as our web application firewall and for DDoS protection, and it performs really well at its job."
"The most valuable features of the Imperva Web Application Firewall are performance and flexibility, and we can extend or customize the box itself."
"IncapRules is one of the most valuable features, as you can create your own security and access control rules on top of your security policy. Using IncapRules we were able to easily block Layer 7 DDoS attacks several times."
"The dashboard is good and user-friendly."
"It's worth it. It's a fine solution for medium/big companies worried about attacks that happen in the wild."
"Well, just by using the security rules to block all secured areas by IP minimized the chance of sensitive data leaking outside."
 

Cons

"The product’s pricing needs improvement."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"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."
"I would like to see analytics, big data."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The web interface could be much better."
"I find that there have been issues in the past year with the solution hanging. It freezes often."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"Imperva Application Security Platform could be improved by providing a more user-friendly dashboard."
"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."
"One thing that they really could improve on is the depth of the analytics."
"Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning."
"Management of policies and rules can be complicated and the physical setup of the product has implications on HA."
"It would be useful if the solution used more intelligence in attack protection."
"Their customer service sometimes has different responses for similar requests. We sometimes need to explain the issue many times before they understand."
"Imperva should have more points of presence in Africa."

"The tool is expensive."
