Cloudflare Birthday Week 2026

[ Simplifying domains for people and agents ]

Cloudflare Registrar's new search delivers fast, transparent results across 420+ extensions using Workers, Durable Objects, and WebSockets. Its expanded API and cf CLI also let agents search, register, and transfer domains.

[ The Internet has a second audience ]

More than half the traffic reaching sites on Cloudflare is now automated, and AI agents are the fastest-growing part of it. We're giving site owners the tools to see who's visiting, decide who gets in, and charge for access.

[ Identify AI model overuse with User Insights ]

AI Gateway User Insights now adds task, model, turn, and user categories to help teams understand AI adoption and make better model decisions. This is available free to AI Gateway users.

[ Cloudflare Impact reaches $100 million in donations ]

This week, Cloudflare's Impact programs will reach $100 million in donated services. This milestone means that thousands of entities including journalists, civil society, state and local governments, election management bodies, and public schools are being protected from cyberattacks.

[ We tested our own WAF with frontier AI models. Here’s what we found ]

We built a WAF tester that adapted each request based on what the WAF blocked or passed. This helped us explore variations that a fixed test might miss. We ran it across six attack categories on an authorized staging environment and discovered detection gaps worth fixing. Here’s how the loop worked, what got through, and what we did about it.

[ Building a certificate authority for the whole Internet ]

Twelve years after launching Universal SSL, Cloudflare is applying to become a certificate authority. By combining an established root, an ACME-first approach, and Merkle Tree Certificates, we are building a post-quantum CA for the open web.

[ Preventing quantum downgrade attacks against IPsec ]

A sophisticated attacker with a quantum computer can exploit a protocol design flaw to downgrade post-quantum IPsec tunnels to classical crypto. We helped the IETF develop a transcript authentication extension to prevent these attacks.
