Criptografia / KMS / HSM | Cybersecurity Service

The problem

Why does your company need this now?

Card data, tax IDs, or health data stored without proper encryption

Poorly managed encryption keys: manual rotation, excessive access, or keys stored alongside the data

PCI DSS or LGPD audit requiring cryptographic protection evidence

Legacy systems with no native encryption capability that need protection without rewriting

FAQ

Frequently asked questions about Criptografia / KMS / HSM

KMS is a software system for managing the cryptographic key lifecycle. HSM is dedicated hardware that performs cryptographic operations in an isolated and certified manner.

With Voltage FPE (format-preserving encryption), the impact is minimal and legacy systems maintain compatibility without schema changes.

Yes, through Evernow's managed services or as part of the sustainment contract.
