Project Galileo: Since 2014, we’ve 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, technology 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’ve 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
- centric public DNS resolver. This is available publicly for everyone to use - it is the first
- focused service Cloudflare has ever released. We do not store client IP addresses, never, ever. We will continue to abide by our privacy commitment and ensure that no user data is sold to advertisers or used to target consumers.
