1. Encrypt the right things

Data in transit (TLS) and at rest.
Sensitive fields (cards, PII, health data).
Backups and removable media.

2. Manage keys properly

Generate, store, rotate and destroy keys securely — ideally in an HSM or managed KMS, with separation of duties.

How CyberSigma helps

We review your cryptography and key management against PCI DSS and best practice, and fix the gaps.

This guide is educational and not legal advice. Requirements evolve — validate specifics against the current standard or regulation for your situation.
