Archana Heeralal - PeerSpot reviewer
A reasonably priced product with a good UI, but the navigation is difficult, and the support team takes a long time to respond
Since we use the solution’s cloud, the product has more control over the back end. The customer will not have control. It is part of the product’s feature. When we get more complex requirements or if we want to write more complex tools, the support team will have the visibility to write them because they have control. The navigation is difficult to use. The navigation should be improved. Other products are quite straightforward. If I try to implement a new application and do an onboarding, it is not very easy. We must go to one feature, inside which there will be more features. It should be simplified, and a menu should be provided.

Multi-layered defense ensures robust protection and optimized resources
Radware DDoS Protection Service is valued for its multi-layered defense protection, always-on and on-demand service, zero-day protection with adaptive behavioral-based mitigation, DNS and infrastructure protection, and SSL attack mitigation. The solution's multi-layer protection covers volumetric, protocol-based, and application layer attacks. They offer a very effective response against DNS attacks. Regarding behavior-based detection technology, in terms of real-time detection, it has been able to reduce false positives. We have pretty good experience with them. The geolocation is pretty good for an organization such as ours. We can block anything from certain regions, like North Korea or China, etc, cetera. It works alongside machine learning. They can update policies globally in less than ten seconds, which really helps with false positives. During a DDoS attack, it ensures legitimate users are not affected. We're working on a hybrid solution, so we have Defence Pro devices on our side and unlimited mitigation capabilities on the cloud.

I highly recommend Cloudflare. We switched from Akamai Prolexic to Cloudflare and couldn't be happier. We also got the worlds fastest DNS and speeded up our site load times with the 200+ edge locations near to our customers.

You can have a look to Imperva Cloud WAF, the anti-DDoS mitigation is under 1s and works very well. I observed a lot of DDoS attacks that were well managed (even not seen by the customer) by Imperva, I can recommend it (try it with a trial, you'll be able to have your own opinion).
