PCI DSS 4.0.1 QSA Audit & AOC Attestation

Audit-ready validation, official Report on Compliance (ROC) sign-off, and SAQ/AOC counter-signing from an active Qualified Security Assessor.

The challenge

Fintechs, payment service providers (PSPs), and merchants face strict card brand mandates to validate PCI DSS 4.0.1 compliance. Multi-layered audit teams from traditional consultancies drag out assessments for months, missing technical context and creating administrative friction.

Our approach

Direct, end-to-end execution led by a former CISO and active QSA who has passed card brand assessments and central bank examinations on both sides of the table. We test controls against PCI DSS 4.0.1 as they actually operate in your environment, and we keep the assessment moving at the pace of your engineering team rather than an audit calendar.

Because the assessor is also the person who scoped the engagement, context from day one survives to the final Report on Compliance. Most clients start with a gap assessment to shrink the Cardholder Data Environment before the official audit, which reduces both the audit cost and the evidence burden on your teams.
