Core PCI DSS requirements

2025

PCI DSS 4.0 full enforcement year

01 The requirement 

## PCI DSS 4.0 Requirements

PCI DSS 4.0 introduces stricter requirements for protecting stored cardholder data, with customised approaches requiring demonstrable security controls.

This is a mapping , not a certification claim. Firevault holds Cyber Essentials Plus. Everything else on this page is stated as alignment: Offline Secure Storage® produces evidence you can point at in your own submission, assessment or audit.

02 What is tested 

## PCI DSS Core Requirements

Each line below is something an assessor, regulator or underwriter can ask you to evidence.

Protect stored cardholder data

Encrypt transmission of cardholder data

Restrict access to cardholder data by business need

Regularly monitor and test networks

03 Consequences 

## Non-Compliance Risks

What happens when the control is missing, and the record cannot be produced.

### Processing Restrictions

Loss of ability to process card payments

### Financial Penalties

Fines from $5,000 to $100,000 per month

### Forensic Audits

Mandatory third-party security assessments

### Increased Liability

Full liability for fraudulent transactions

04 The architecture 

## How OSS Supports PCI DSS Compliance

Offline Secure Storage removes cardholder data from network-accessible systems, directly addressing multiple PCI DSS requirements.

### Network Segmentation

Physical disconnection is the ultimate network segmentation

### Access Control

Identity-verified access with full audit trails

### Encryption

Hardware-level encryption for all stored data

### Scope Reduction

Reduce your CDE footprint by moving archived data offline

05 What sits offline 

## Payment Data Protected

The records most often moved into Offline Secure Storage® for this framework.

Archived cardholder data

Transaction records and logs

Payment processing documentation

Security audit evidence

Key management records

Compliance assessment reports
