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.
Limelight Networks is an Arizona-based CDN provider that owns and operates its own content delivery network. The company was founded in 2001 and has offices in the US, Europe and Asia.
Limelight offers regular CDN services for static content, website acceleration, video streaming (Limelight Orchestrate) and cloud storage. Some of the services in the Limelight portfolio came to be from a variety of acquisitions done by the company in the past. Acquired companies include AcceloWeb (website acceleration), Kiptronic (video) and Delve Networks (video).
In 2006, the CDN provider was sued by Akamai Technologies, Massachusetts Institute of Technology (MIT) and later by Level3 over alleged patent infringements. In 2015, after a long string of decisions, came an end to the back-and-forth between Akamai and Limelight: Limelight was held liable for direct infringement of an Akamai-held patent by the US Court of Appeals for the Federal Circuit. In response to the ruling, Limelight Networks (NASDAQ:LLNW) fell greatly.
As of today, Limelight is still fighting a portion of the August 2015 decision, prolonging an already long-standing dispute against Akamai.
Limelight serves, or has served notable customers such as Disney, EA Sports, MySpace, Harpo Productions, MTV, Nintendo, Heineken and Carrefour. With the exception of the latter two, these customers are seemingly no longer with Limelight.
