Fastly Edge Cloud Platform vs. Imperva CDN

The service is really well-suited for pretty much any site that is primarily display-driven (that is, mostly GET requests). The network is able to handle massive volumes of traffic and their POPs have spread out pretty much anywhere that it's easy to get them (so basically everywhere but China and Russia). My team witnessed several large-scale attack attempts on some high-profile websites (attacks in the 10s of millions of requests per second) that were mitigated before ever coming back to the actual application; in one case we didn't realize the attack had happened until we looked at the logs the next day. Because it's a cache store option, the default configuration does not cache POST responses, and it can be difficult to set up things like authenticated paywalls as a result.

Incapsula really exceeds if you have a very large amount of traffic, it is a truly durable and resilient WAF. Global load balancing, increased security, added caching, smaller number of sites (but very important)? Then I would recommend Incapsula. Incapsula is always additive to features your infrastructure has and it does those well, so I would always advise using it if your site has high traffic, is business critical, or accesses sensitive information through a SQL backend.

• Setup can be difficult -- but only because the service is so robust and provides so many features.
• Minimum spend is $50/month, even if you are not using the service enough to have spent the $50.

• CDN functionalities are secondary and cannot be compared to a top-level CDN.
• The WebGUI interface of the dashboard is very improvable. They have been changing the UX for years and it is disjointed and with services that have not yet been migrated.
• The analysis of WAF attack logs is insufficient. It is difficult to analyze attacks of past hours, event filters are missing. It is complicated to analyze the chronology of an attack.
• There are extra modules to improve the attack logs analysis but they are expensive and add little.

Fastly Edge Cloud Platform is a powerful tool with robust capabilities, but it requires deep technical knowledge to integrate effectively into existing applications. While its performance and features are excellent, the lack of a user-friendly interface and the need for advanced configuration can make it challenging for teams without experienced developers.

Fastly is a great choice for CDN vendor when performance and has the ability to quickly invalidate an asset from all POPs very quickly. It shines in use cases that require media delivery, like video. Fastly also provides a highly-optimized way to handle logical operations at the edge, meaning that, for example, quick authorization checks can be handled without having to work with the origin server.

• While I was at Wanelo we were able to put Fastly in front of the growing web app, and selectively cache end points to improve stability and performance. In the meantime we rewrote the app completely in Ruby. We wouldn’t have been able to do that without Fastly.

• It's an expensive product if you have a lot of traffic volume, but I feel confident with their WAF.
