| Description: | CloudFlare is a content delivery network and distributed domain name server service marketed as improving website performance and speed and providing security. CloudFlare has both free and paid services. CloudFlare received media attention, not all of it positive, after providing security to LulzSec's website. The Turkish government has also used CloudFlare.
Matthew Prince, Lee Holloway, and Michelle Zatlyn created CloudFlare in 2009. They previously worked on Project Honey Pot. CloudFlare was launched at the September 2010 TechCrunch Disrupt conference.
In October 2011, CloudFlare named as the Most Innovative Network & Internet Technology Company of 2011 by Wall Street Journal. |
