Imperva CDN Reviews & Insights

I use it mainly as a WAF (Web Application Firewall) although I also use certain CDN cache functionalities.

I recommend it as a WAF, but not as a CDN. There are better CDNs, in my case I use transparentCDN (now www.transparentedge.eu) and Edgecast (now Verizon CDN).

Incapsula, for us at Provident, adds compensating controls for performance and security. We use Incapsula for our whole organization with all external and some internal-use-but-public sites. We are very impressed with Incapsula's reliability and security as we have had no known issues during our years of use in the organization with their service. Penetration testers have found it so frustrating we allow them to circumvent the service in order to better test and secure our applications and infrastructure.

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.
