Cloudflare builds a post-quantum certificate authority with Merkle Tree Certificates
Cloudflare says it is becoming a certificate authority that will support Merkle Tree Certificates (MTCs), with a target of early 2027 for inclusion in Chrome’s quantum-resistant root store. The company will offer standard MTC issuance at no cost, aiming to provide a scalable post-quantum upgrade path for web authentication while keeping certificate transparency as a first-class property.

Cloudflare CT Monitoring becomes generally available with noise filtering
Cloudflare says its Certificate Transparency Monitoring feature is now generally available after adding filtering to suppress alerts for certificates it issued on behalf of customers. The change reduces noise from routine renewals so customers can focus on unexpected certificates that may indicate mis-issuance or other risk.

Role implications

HoldAssessConfidence32%

Business✦ Emerging
For BD, Certificate Transparency moving up to Assess means customer and partner conversations should start focusing on trust, transparency, and the adaptability of certificate infrastructure. Cloudflare’s post-quantum certificate authority with Merkle Tree Certificates suggests this may become a technical differentiator in sales or partnerships, but it should be framed as an emerging capability rather than a finished advantage.
Developers✦ Emerging
As Certificate Transparency moves from Hold to Assess, developers need to treat certificate issuance and rotation as part of system design, not just infrastructure setup. Cloudflare’s post-quantum certificate authority with Merkle Tree Certificates shows that CA choices and certificate logging are changing, so code and deployment workflows need to be ready for those new assumptions.
Product→ Steady
For product managers, Certificate Transparency being promoted to Assess means it is not yet a roadmap commitment, but it is important enough to track as a foundational capability that can affect security and trust. Cloudflare’s news points to post-quantum and Merkle Tree Certificates, so PMs should assess whether these changes affect product requirements, compliance, or customer messaging.
Testers / QA✦ Emerging
With Certificate Transparency now in Assess, testing needs to expand beyond basic TLS connectivity into certificate issuance, renewal, and verification flows. Cloudflare’s Merkle Tree Certificates news is a reminder that assumptions about certificate structure and transparency can change, so tests should cover failure cases and compatibility around new certificate chains.
