What Makes Cloudflare Special?

We’re not just a highly ambitious, large‑scale technology company. Fundamental to our mission to help build a better Internet is protecting the free and open Internet.

Project Galileo: Since 2014, we have equipped more than 2,400 journalism and civil society organizations in 111 countries with powerful tools to defend themselves against attacks that would otherwise censor their work. These services are already used by Cloudflare’s enterprise customers at no cost.

Athenian Project: In 2017, we created the Athenian Project to ensure that state and local governments have the highest level of protection and reliability for free, so that their constituents have access to election information and voter registration. Since the project, we have provided services to more than 425 local government election websites in 33 states.

1.1.1.1: We released 1.1.1.1 to help fix the foundation of the Internet by building a faster, more secure, and privacy‑centric public DNS resolver. It is available publicly for everyone to use – we do not store client IP addresses and never sell user data to advertisers.
