Cloudflare, which terminates TLS for millions of domains and sits in front of over 20% of global Internet request traffic, announced its intent to become a public certificate authority (CA) during Birthday Week 2026. The company has applied for inclusion in the Chrome, Apple, Microsoft, and Mozilla root programs and signed a definitive agreement to acquire an established root from GlobalSign. This acquisition ensures certificate compatibility with older clients that a fresh root would never reach, addressing the long tail of devices where avoidable breakage occurs. Cloudflare plans to be among the first CAs to issue production Merkle Tree Certificates (MTCs) in early 2027, targeting post-quantum readiness as part of Chrome’s Quantum-resistant Root Program. The CA will be ACME-first, require ACME Renewal Information (ARI) support for issuance, and operate transparently with reproducible builds of signing software and a public dashboard.
