The tool offers very good performance, even during high-traffic periods.
Engineer at SITMEXICO

99% of customers are using the cloud version of Imperva DDoS protection, so they just purchase the new license and scale as needed.

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

Users suggest improvements in Cloudflare's features, pricing, support, analytics, documentation, and partner relations for better service experience.
Users seek improved interface, integration, real-time monitoring, support, pricing, reporting, and enhanced security features from Imperva's platform.
Enhance Link11 with intuitive interfaces, real-time alerts, automated reporting, improved WAF, unified panels, and better bot management.
Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements.
General Manager at bKash Limited
There are some performance considerations when it comes to dynamic content that involves fetching data from databases or using APIs.
Senior Solutions Architect at Think Power Solutions
What Cloudflare is doing internally is that it is stepping ahead in areas like detection and protection.
Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
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 Solutions Architect at Think Power Solutions
The tool is a premium product, so it is very expensive.

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.

Principal Cyber Prevent and Defense Engineer at a comms service provider with 1,001-5,000 employees
Most of our DNS records that are presented to the internet are proxied whenever possible, providing another layer of defense from our perspective.
Senior Security Engineer at ManpowerGroup
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.

Advanced protection has secured critical web workloads and provides clear traffic visibility
From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

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.

Offers flexibility with a kill switch for bypassing Reblaze if needed and provides a reliable Layer 7 defense against attacks
There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town. AWS WAF, the Web Application Firewall from AWS, has a vast database of bad IP addresses due to its long-standing presence in this business. Reblaze, being a new entrant, is still building its database of bad IP addresses and malicious systems. So, Reblaze needs to work on that aspect. But other than that, I don't think scaling Reblaze has been an issue. There were some initial glitches, but they were all sorted out. So currently, I would say that the bot management and the database are areas they should focus on for further improvement.
