We performed a comparison between Fastly and Imperva DDoS based on real PeerSpot user reviews.
Find out in this report how the two CDN solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Rate limiting is a good feature that protects from volumetric attacks."
"Compute@Edge features are valuable to me."
"Its initial setup process is straightforward."
"The product helps our organization to access sites located in different regions quickly."
"It blocks all types of attacks."
"The most valuable features for us are the DDoS and Bot."
"There is no need to have an appliance in house for the services because it is on the cloud."
"The dashboard is good and user-friendly."
"This product is a reliable defense from malicious attacks on a network environment."
"The most valuable features are DDoS protection."
"Its unique interface for managing security performance and ease of use are the most valuable features of this solution."
"An improvement has been to our website: It increases the speed of our response, the capacity of the site, and optimizes the bandwidth."
"The solution's pricing could be better."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"The product should provide improved bot detection and management."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"Support is not that great."
"Fastly's customer service area needs improvement."
"Some maintenance must be performed by our IT team."
"It needs to be improved every time there are new attacks."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side."
"Users would benefit from better documentation. There is official documentation, but sometimes we need more detail. We have some use cases that are not so run of the mill. It would be great if there was a knowledge base that we could go to for more answers."
"It would be beneficial to include vulnerability management in the solution, similar to what they have for their on-premise solution."
"The rules surrounding the making of web applications could be improved."
"Imperva now offers add-ons to add functionality, but I would like to see these included in the product, even if it would cost more."
