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."
"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."
"It allows me to see all the traffic on my network."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"The protection resources and the support are valuable features of the solution."
"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."
"It is a user-friendly product in terms of monitoring and updating policies."
"Imperva makes it easier for us to put everything in code; we use Terraform to deploy our infrastructure."
"We are using Incapsula as our web application firewall and for DDoS protection, and it performs really well at its job."
"The most important feature I have found to be the ease in how to do the backup and restores."
"The Imperva Web Application Firewall feature I have found the most valuable is the ease of deployment."
"Integration with IBM AS/400 and Db2 is okay."
"Initially, there were over 1,500 vulnerabilities, but we managed to fix almost all of them within three months, leaving only two low severity issues outstanding."
"The solution has a very good interface."
"Bad-IP blocking and signature-based blocking for web application security."
 

Cons

"Alerts and reporting features must be improved."

"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."
"Earlier versions of firmware had bugs that limit my options."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"Reporting and the main Sites dashboard could use refinement."

"The tool is expensive."
