Our delivery process

Our four step process

Cythera’s PCI DSS v4.0 Gap Assessment uses a clear, four-stage approach to evaluate your compliance. Starting with a kickoff meeting and scope validation, followed by onsite or remote assessment and a detailed report, we provide insight into your current state and offer practical steps to improve security controls. This assessment helps you prove your dedication to securing cardholder data and strengthening your overall security posture.

Scoping & planning

We begin with a discovery call to understand your setup and clarify which systems should be included in the assessment.

Evidence collection

We validate your implementation through detailed document analysis and remote stakeholder interviews.

Findings & recommendations

You’ll receive a clear, written assessment outlining compliance gaps, practical remediation guidance, and a roadmap to improve your PCI DSS security posture.
