Incapsula Inc. provides a variety of CDN services, from the network itself to security, load balancing, failover solutions and DDoS protection. The company spun out from data security company Imperva in 2009. Incapsula launched Botopedia in 2012, a directory that includes community-sourced information about bots.
At the core of Incapsula’s feature offering lies the content delivery network and a variety of security features such as web application firewall (WAF) and DDoS mitigation.
Incapsula composes comparison tables of its own, which can be viewed on their website - providers they compare themselves to are Akamai and CloudFlare. In the comparison tables they dive deeper into the various security features within the content delivery ecosystem.
Like most other CDN providers, Incapsula integrates well with a variety of Content Management Systems (CMS) and also offers a downloadable extension on their website for Joomla. The extension improves security and performance for Joomla. Other security solutions for third parties offered by Incapsula are targeted at clients hosting with Rackspace, Microsoft Azure and Amazon AWS. All three of these also offer their own CDN solution.
In 2014, Comcast debuted their CDN service. With their own CDN in place, Comcast can deliver a better experience to their already existing consumer base. Unique in the CDN landscape, we can label Comcast a B2C CDN service provider.
As the ISP, cable owner and CDN provider, Comcast is able to offer an excellent SLA and potentially lower pricing, when compared to 3rd party CDN providers who do not own the network they operate on.
The Comcast CDN is regional and offers PoPs within the US only. The CDN service is therefore not suited for businesses with a global userbase, unless it is combined with other CDN providers in a multi-CDN setup. Warpcache is a multi-CDN provider that offers the Comcast CDN in combination with others.
Comcast is a very suitable provider for a multi-CDN setup. Warpcache resells multiple providers, both in an integrated multi-CDN solution and separately.
