Change detection
Can it detect and preserve material changes over time?
What is change detection?
Cryptographic change detection identifies when assets, configurations or dependencies appear, disappear or materially change after the initial inventory.
Post-quantum readiness is not a one-time scan. Buyers need to distinguish pipeline processing latency from the total time between a real target change and its discovery.
Questions to ask a vendor
- What triggers a new observation?
- How often are all authorized surfaces revisited?
- Are change records signed, ordered and protected against deletion or reordering?
