Who Actually Owns Quantum Readiness? Shared Responsibility and Crypto Agility

This is the final episode of The PQC Playbook, and I want to end with a question that sounds simple: who actually owns quantum readiness?

Is it your cloud provider, your security team, your PKI team? Application owners? Vendors?

The answer is all of them.

Shared responsibility is the right frame

Google recently published its own PQC roadmap, and one idea that stands out is shared responsibility. Google is responsible for making its infrastructure quantum-ready. Customers remain responsible for their applications, workloads, data, and the cryptography they control.

That distinction matters.

AWS can migrate AWS. Microsoft can migrate Azure. Google can migrate Google Cloud. None of them can migrate your enterprise for you.

What still sits inside your walls

Your applications still have dependencies. Your vendors have their own timelines. Some applications will not support quantum-safe cryptography yet. Some hardware will need upgrades. Some systems may need to be replaced entirely.

Somebody inside your organization has to coordinate all of that. Cloud roadmaps and vendor announcements help, but they do not replace enterprise ownership of the work that only you can see and only you can sequence.

Why it cannot belong to one team

Quantum readiness fails when it is treated as a single team's project.

• Security can establish policy
• Cryptography and PKI teams can provide expertise
• Infrastructure can modernize platforms
• Application owners can make changes
• Business owners can determine what matters most

Those roles are necessary. They are not sufficient on their own. Somebody has to bring the pieces together into one operating model: discovery, context, prioritization, dependency mapping, ownership, planning, execution, and continuous adaptation as cryptography changes.

That has been the point of this series

Across ten episodes, the thread has been practical:

• Know what cryptography you have
• Understand where it is used
• Prioritize what matters
• Map the dependencies
• Establish ownership
• Build a migration plan
• Execute it
• Keep doing it as cryptography changes

Quantum readiness is not something one vendor, one cloud provider, or one security team can hand you. It is a capability your organization has to build. That capability is crypto agility.

If you are putting that model in place across discovery, ownership, and migration execution, our PQC Readiness page outlines how Axiad works with enterprise and federal teams. You can also run a quick external check at quantum.axiad.io.

Closing the playbook

Ten episodes. One practical question at a time. I hope it made a complicated migration a little easier to understand.
