Pricing questions
Locations, payment channels, terminals, e-commerce integrations, in-scope systems, service providers, segmentation, validation path, testing evidence, and documentation condition determine effort.
This page describes readiness and security consulting, not a QSA attestation. Organizations that require formal assessor validation should confirm the applicable PCI SSC program and qualified assessor requirements.
The review can identify scope drivers and possible segmentation or architecture improvements. Any scope-reduction decision must be supported by the actual data flow, controls, testing, and applicable validation requirements.
