2026 Futuriom: Implementing Crypto-agility for PQC Networking Infrastructure

Highlights:

• The post-quantum era is getting real for networking and cloud infrastructure, with governments setting timelines for compliance and CISOs and boards actively engaged in quantum readiness initiatives.

• For enterprise infrastructure leaders, the challenge is broader than just replacing current cryptography standards and algorithms.

• Infrastructure leaders need to think about the security and post-quantum readiness of the entire estate, including networks that cross domain boundaries such as multicloud and telecom networks.

• Organizations need not only consider what happens to their encryption keys and security protocols, but how they are handling data in motion as well as data at rest. They also need to consider architectural flexibility with the capability to see the entire infrastructure and make real-time changes with software.

• A significant networking infrastructure refresh cycle is an opportunity to remove infrastructure that cannot be upgraded, standardize policy, improve segmentation, and move more controls into software. It’s also a good reason to align with PQC rather than having a separate cryptography project.
