We’re building CryptoLabe, an internal AI-powered tool that discovers cryptography across our codebase, surfaces dependencies, and helps us progress toward a full post-quantum migration by 2029. Here’s what we’ve learned so far.
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.
As post-quantum signatures threaten to inflate TLS handshakes and certificate transparency logs, Merkle Tree Certificates offer a path to compact, auditable authentication. Cloudflare’s new certificate authority will support MTC issuance at scale.
We are expanding access to Cloudforce One's Threat Events Platform to every Cloudflare account and introducing Threat Signals. Threat Signals automatically parses open-source threat reporting, extracts structured indicators, and connects threat context directly to your WAF rules.
Cloudflare has added visibility into post-quantum (PQ) encryption in TLS 1.3 directly into HTTP Analytics, Log Explorer, and Logpush. Learn how to make sure your domain is protected with PQ encryption.
Cloudflare learns the structure of your HTTP requests and identifies deviations. You can add a positive security layer that helps reduce attack surface as AI makes it easier for attackers to generate and vary payloads.
