TL;DR: The G7 Quantum Technologies Working Group says quantum threat timing is uncertain, but harvest now, decrypt later collection is already underway and NIST deadlines compress migration windows, according to AppViewX. Practitioners need crypto-agility, because discovery and automated change control now determine whether PQC can be delivered at scale.
Editorial analysis by NHI Mgmt Group, based on content published by AppViewX: “The G7’s PQC Warning for Enterprise Security”.
Key questions
Q: What happens when certificate management is automated before a post-quantum migration?
A: Automating certificate management creates a cleaner foundation for post-quantum transition work because teams can discover assets faster, renew certificates consistently, and update cryptographic settings with less manual effort.
Q: Why do hybrid cryptography deployments matter during PQC transition?
A: Hybrid cryptography matters because it lets organisations introduce quantum-resistant protection without breaking interoperability in existing systems.
Q: How should teams inventory cryptographic assets before PQC migration?
A: Teams should inventory every cryptographic asset by key type, algorithm, certificate issuer, key length, usage, expiry, and where it is embedded, including code, HSMs, secrets stores, and device firmware.
Practitioner guidance
- Build a complete cryptographic inventory Map certificates, keys, algorithms, renewal owners, and dependency chains across cloud, on-premises, and hybrid environments before setting migration dates.
- Automate certificate lifecycle workflows Use closed-loop discovery, enrollment, renewal, and deployment processes so cryptographic changes can be executed repeatedly without manual bottlenecks.
- Prioritise long-lived data systems Rank systems by confidentiality horizon, starting with workloads that protect sensitive information for years or decades and are most exposed to harvest now, decrypt later risk.
Bottom line: PQC migration is an operational change programme, not a simple cryptographic swap, because discovery, policy control, and deployment all have to scale together.

Crypto-agility is the real PQC control plane: The central challenge is not choosing quantum-safe algorithms, but building an environment that can discover, approve, deploy, and validate cryptographic change repeatedly. That shifts PQC from a one-time migration project to an ongoing governance discipline spanning PKI, applications, infrastructure, and vendors. Organisations that still treat algorithm selection as the main task will miss the operational bottleneck that actually determines progress.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should development and security teams do first to reduce quantum and AI risk together?
A: Development and security teams should begin with practical readiness work: map where cryptography is used, pilot post-quantum controls, and expand AI security governance at the same time. The article also recommends using AI security frameworks such as NIST AI RMF and MITRE ATLAS, while building the monitoring and detection capability needed to spot risky AI usage early.
