Cloudflare’s network and business are all ultimately built on customer trust. We seek to continually earn and maintain that trust not only with privacy-first policies and procedures that guide how we manage customer and end-user data on our systems but also by building privacy into our products and services. For this reason, we are constantly improving the security of our systems, we encrypt data at rest and in transit, and we allow our customers to determine how traffic is inspected across different locations around the world.
This whitepaper breaks down how Cloudflare uses security measures to protect data as it crosses our network and analyze the metadata.
Part 1 explains how data traverses our global edge network of data centers and how we incorporate encryption into that network to guarantee privacy.
Part 2 explains how we use encryption to protect the metadata we collect from that edge network.
Part 3 discusses our protection of encryption keys so that our encryption cannot be broken.
