One notable drawback is that, unlike Fortinet, which offers fast track labs and continuous enablement, Imperva Application Security Platform lacks lab access and fast track labs for enablement and product advertising.

We experienced downtime or crashes with Imperva Application Security Platform when traffic went really strong or fast because people tried to get tickets.

Room For Improvement

A10 Thunder TPS needs better training, smoother upgrades, improved documentation, and enhanced synchronization, with concerns over UI and virtual training.

To convince my clients, a purely on-prem solution would be ideal since they are financial institutions.
CTO at Malam Engineering PLC
Maybe Imperva DDoS could use endpoints to get information about the attacks before they commence from the endpoint level or establish cooperation with endpoint vendors to share this information.
Head of Sales Services Department at a comms service provider with 51-200 employees
Regarding return on investment, ROI, I can say it is noticeable with Imperva Application Security Platform.

Setup Cost

Enterprise buyers find A10 Thunder TPS pricing mixed, highlighting both value and expense, with multiyear deals as beneficial.
Imperva's Application Security Platform has high, complex pricing, yet some find it competitive for its security benefits and enterprise flexibility.
The global price list is not accessible, making it difficult to work.
Information Technology Security Engineer at a tech services company with 11-50 employees
I would rate the pricing of Imperva DDoS as five, where one is very cheap and ten is very expensive.
Head of Sales Services Department at a comms service provider with 51-200 employees
the setup cost was high, with the hardware installation in the data center being particularly expensive.
Cyber Security Product Owner at a energy/utilities company with 10,001+ employees
We have noticed faster response times and fewer security alerts because after doing some custom policy tuning, everything seemed to be aligned and we have fewer attacks to monitor and fewer alerts to monitor.
Senior Cybersecurity Consultant at Cyberoutcome Limited
 

Valuable Features

A10 Thunder TPS excels in traffic filtering, DDoS mitigation, load balancing, and offers programmable automated defense with RESTful API.
Imperva Application Security Platform offers robust threat protection, user-friendly interface, and comprehensive reporting for enhanced web security management.
The vendor indicated that Thunder would not be supported, but I was able to add Thunder to the central console management.
Information Technology Security Engineer at a tech services company with 11-50 employees
The API security feature is particularly valuable because most attackers do not try to come in from where it is expected.
Senior Cybersecurity Consultant at Cyberoutcome Limited
If someone attempts to access the server, the WAF blocks that SSRF alert, or RCE, Remote Code Execution alert, blocking immediately based on the signature, not only by the payload or the IP address.
SOC Analyst L1 at CMS-IT-SERVICES-PVT-LTD
It reduces the DDoS attacks and reduces the attacks from threat actors, including SQL Injection and zero-day attacks, by using dynamic application profiling from Imperva.

Featured Reviews

reviewer1126782 - PeerSpot reviewer
Information Technology Security Engineer at a tech services company with 11-50 employees
Management console adds value and technical support delivers timely solutions
I had issues with the user interface because, when putting settings up, the system asked me for strange things like virtual local networks that I didn't create. For example, I set an NTP server, and after some clicks, a message appeared stating 'setup is incorrect'. It asked for a VLAN even though no VLANs were created. We had to find workarounds for issues like A10 blocking necessary traffic, sometimes leading to decreased security, because it was the simplest way to deal with them. This was a real issue. A more flexible policy for demo licenses would also be helpful.

Senior Associate at a tech vendor with 10,001+ employees
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.
