PCI DSS & Payment Security Advisory

Scope reduction first, compliance second, cost third.

The situation

PCI DSS v4.0 requirements that were best practice became mandatory on 31 March 2025, and most merchants and service providers are still paying to protect data they never needed to hold.

We start with scope reduction — tokenisation, redirect and hosted-field patterns, network segmentation — because every system removed from scope is a permanent reduction in cost and risk, then take the residual estate to full compliance.
