Post-Quantum Security Testing

MICROSOFT CORP · 2026-09-17 · Importance 31 · Surprise 42

Microsoft is testing post-quantum cryptography interoperability with certificate authorities including DigiCert. The work focuses on making quantum-resistant security deployable across existing customer infrastructure rather than treating cryptographic novelty as the primary objective. The controlled testing environment is intended to identify compatibility issues before broader deployment. This positions Microsoft to support enterprise certificate and identity migrations as customers prepare for quantum-related security risks.

Key facts

• Microsoft is testing post-quantum cryptography interoperability with certificate authorities like DigiCert to ensure practical and deployable solutions for the quantum era. source
