Find cryptography that actually touches a retailer's card-data environment
Which terminals, gateways, token services, applications, and vendors are inside or connected to the cryptographic scope?
Operational pain
Network diagrams and SAQs miss keys and certificates in integrations, support tools, batch settlement, ecommerce plugins, and backup.
Trigger
PCI assessment, payment-platform change, acquisition, or cryptographic migration.
QNSI contribution
Connect the decision to a controlled security path
Use QNSI inventory to associate algorithms, keys, endpoints, owners, vendors, and observed data paths with the CDE.
Decision artifact
A card-data cryptography register with scope rationale, unsupported dependencies, key owners, and evidence status.
What still requires validation
The merchant and assessor determine PCI scope, segmentation, compensating controls, key ceremonies, and compliance.
External problem context
Primary sources
These sources establish the external requirement or risk context. They do not endorse HEOSSI or prove that QNSI completed this scenario.
Evidence boundary
What this page does—and does not—prove
This is a product evaluation pattern, not a customer case study, certification, legal opinion, regulator endorsement, or claim that a production deployment completed the described work.
