TL;DR: Quantum computing is turning “harvest now, decrypt later” into an immediate governance problem because organizations often cannot see where sensitive data is encrypted, what keys protect it, or which datasets carry the highest business impact, according to BigID. The practical lesson is that readiness starts with data exposure mapping and key visibility, not an abstract cryptography refresh.
Editorial analysis by NHI Mgmt Group, based on content published by BigID: “Quantum Readiness Starts with Your Data, Not Your Algorithms”.
Key questions
Q: What breaks when organisations treat quantum-safe encryption as a future problem?
A: Long-retention data remains vulnerable to harvest-now, decrypt-later collection, because attackers can store encrypted traffic today and wait for quantum capability to catch up.
Q: Why do keys and secrets matter so much for quantum risk?
A: Because encryption is only protective when the surrounding key and access governance is tight.
Q: How do security teams decide which encrypted data to protect first?
A: Prioritise by sensitivity, retention, and downstream use.
Practitioner guidance
- Discover encrypted data across every environment Build an inventory of encrypted data across cloud, SaaS, on-prem, structured stores, unstructured stores, and AI pipelines so exposure can be assessed before migration planning begins.
- Map keys, secrets, and credentials to their data owners Identify where encryption keys, API keys, tokens, and embedded secrets live, who can reach them, and which datasets depend on them for protection.
- Rank datasets by sensitivity and business impact Separate high-value data such as PII, PHI, financial records, and intellectual property from lower-risk encrypted assets so remediation effort follows exposure, not inventory size.
Bottom line: Quantum readiness fails when teams focus on future algorithms but cannot yet see where sensitive data is encrypted or which keys protect it.

Quantum readiness debt: organisations that treat post-quantum cryptography as the whole answer are carrying a governance gap, not just a technical migration challenge. The missing control is data exposure visibility, because you cannot prioritise what you cannot see. The practical conclusion is that readiness starts with knowing which datasets would matter if current encryption were broken.
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.
- 96% of security operations teams report critical blind spots, most commonly in cloud infrastructure (74%) and identity and access behaviour (67%).
A question worth separating out:
Q: What should organisations do when encrypted data and keys are spread across many systems?
A: They should build a single exposure view that ties datasets to keys, secrets, and owners. That makes it possible to see where broad access, data sprawl, or weak cryptographic governance creates avoidable future risk. Without that linkage, quantum planning stays theoretical and remediation stays unfocused.
