The Cloudflare mission

Here are some ways we're working to improve the Internet, for everyone:

1.

Encrypting the Web

In 2014 Cloudflare was among the first services to offer free HTTPS support to all users — helping jumpstart a massive, industry-wide trend toward a more secure Internet. Back then they called us crazy; today over 80% of Internet traffic is encrypted, and we continue to patch the Internet’s core security bugs.

Defending Democracy

Democracy faces grave threats from malicious online attacks. With The Athenian Project, Cloudflare works hand-in-hand with American government and election sites to ensure they stay online during critical moments, like when citizens are headed to the polls.
