Summary

Cloudflare is preparing to become a Certificate Authority itself after acquiring a GlobalSign root certificate, motivated by the systemic risk of relying on Let's Encrypt's concentration in the free TLS certificate market. The move raises questions about whether it will decentralize Web PKI or create an even larger central point.

Let's Encrypt issues about 10 million free TLS certificates every day, serving over 500 million websites, and Cloudflare itself is one of its largest users. But now, Cloudflare is preparing to become a CA itself. Even more interesting is that Cloudflare has already acquired a GlobalSign root certificate trusted by mainstream browsers, operating systems, and devices. Why do it themselves? Cloudflare's reasoning is straightforward: Free certificate CAs are too concentrated, posing systemic risks. If Let's Encrypt experiences a large-scale outage, most websites currently lack an equally free, automated, and widely compatible alternative. This is actually a fascinating issue in internet infrastructure: Once an open-source/free infrastructure becomes extremely important, its concentration itself can become a risk. Will Cloudflare becoming a CA itself make Web PKI more decentralized? Or will it create another, even larger central point?
