Microsoft has officially introduced initial post-quantum cryptography (PQC) support for Active Directory Certificate Services (AD CS), marking an important milestone for enterprise PKI teams. With ML-DSA support now available in Windows Server 2025 environments, organizations can begin evaluating what post-quantum certificate issuance and signature algorithms mean for their PKI architectures, operational processes, and long-term cryptographic strategy.

In this webinar, Mark B. Cooper will be joined by Tanya Jha, Senior Product Manager at Microsoft, to discuss guidance and practical considerations for organizations preparing for the transition to post-quantum cryptography in AD CS environments.
