Imperva Application Security Platform provides scalable, adaptable security solutions with centralized management, despite some regional and pricing issues.
For those opting for a SaaS or cloud solution, there is scalability and flexibility.
Senior Technical Engineer at Safezone Secure Solutions Private Limited
It is scalable for some versions, however, as components reach their end of support, upgrades are necessary to maintain scalability.
Security Network Architect at novonordisc
99% of customers are using the cloud version of Imperva DDoS protection, so they just purchase the new license and scale as needed.
Head of Sales Services Department at a comms service provider with 51-200 employees

Sentiment score
7.9
The Imperva Application Security Platform is highly stable with minor issues like link degradation and rare false positives.
The support system is reliable when issues like automation or configuration arise.
Security Network Architect at novonordisc
Overall, it has been good; in the past it was very good, and now it is still performing well.
Senior Technical Engineer at Safezone Secure Solutions Private Limited
We have two applications in two ESXi hosts that I integrated into our ADC, and I created one virtual IP in the virtual server pool.
Team Lead at Adapt Information Technologies (Pvt) Ltd
It is also a stable product without much glitch or downtime.
Senior Presales Consultant at Techlab security
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.
CTO at Malam Engineering PLC
The stability of Imperva DDoS is very good, as it seems they have a lot of servers around the world.

Room For Improvement

Fortinet FortiADC users seek better support, documentation, and features, including load-balancing, security, interface, and resource optimization improvements.
Users seek improved interface, integration, real-time monitoring, support, pricing, reporting, and enhanced security features from Imperva's platform.
Fortinet has been a pioneer for enterprise solutions, such as firewalls, SASE, ZTNA, and SD-WAN solutions, and they are in a leader quadrant.
Senior Technical Engineer at Safezone Secure Solutions Private Limited
The limitation of managing all components and the differing versions pose challenges.
Security Network Architect at novonordisc
If I need design help, they do not assist; they say it is a design issue they cannot support, and I must approach the system integrator.
Senior Network Engineer at SP SYSNET PTE. LTD.
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.
Senior Presales Consultant at Techlab security
 

Setup Cost

Fortinet FortiADC offers competitive, predictable pricing with flexible licensing options, appealing to both small businesses and large enterprises.
Enterprise users find Imperva's pricing high and complex, but value its robust security features despite costs.
This solution is quite expensive compared to Kemp.
Senior Network Engineer at SP SYSNET PTE. LTD.
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
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
The pricing is not transparent to me; it's what the vendors give, or whatever the channel partner offers that you can negotiate on.
Head of Tech at CRC Credit Bureau Limited
 

Valuable Features

Fortinet FortiADC offers features like SSL offloading and load balancing, valued for simplicity, scalability, affordability, and integration.
Imperva Application Security Platform excels with easy setup, strong DDoS protection, dynamic profiling, and advanced threat intelligence.
I use server load balancing and employ layer seven features, which provide more granular traffic shaping and detailed logs.
Senior Network Engineer at SP SYSNET PTE. LTD.
When integrated with FortiAnalyzer, it has much more significance.
Senior Technical Engineer at Safezone Secure Solutions Private Limited
The implementation process is straightforward, and cluster implementation is also very easy.
Team Lead at Adapt Information Technologies (Pvt) Ltd
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.

GANESAN K - PeerSpot reviewer
Senior Technical Engineer at Safezone Secure Solutions Private Limited
Has supported load balancing for medical applications and could benefit from more custom configuration options
Some customers need custom management for handling their applications across the servers. Instead of having a predefined solution, if we had space for custom-based algorithms to load balance the traffic, it would be better. We have faced such cases with A10, where we can leverage many custom scripts and do much more. Even though A10 primarily focuses on SMBs, they have also ventured into the enterprise market. Fortinet has been a pioneer for enterprise solutions, such as firewalls, SASE, ZTNA, and SD-WAN solutions, and they are in a leader quadrant. Therefore, they should have more options. From a pricing perspective, it is expensive.

Senior Cybersecurity Consultant at Cyberoutcome Limited
Strong policies and bot defenses have secured critical APIs and have reduced attack noise
From my research regarding the IAM space that Imperva Application Security Platform is trying to look into, I believe they still need to do a lot of modeling and modification to make sure that also helps. There are several competitors in the IAM space, so Imperva would do well if they can do some basic modeling and modifications from my own personal research and my own experience in the IAM space. Alternatively, they could actually just focus on trying to be stronger in the web application space and the database activity monitoring space.The main reason it is not a perfect ten is regarding support. At times, having to reach the support team takes eight hours to ten hours maximum. There are times when clients could have urgent issues to attend to. The support team could do more by having a faster response rate.
