Protect cardholder data and secure payments with PCI DSS.

At GRSee Consulting, we handle the entire process for you: from readiness and implementation to testing and auditing (ROC), and Compliance as a Service.

We are proud to be the 1st QSA Company globally to audit a fully cloud-hosted PCI DSS environment.

The Payment Card Industry Data Security Standard (PCI DSS) is a set of security standards designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment.

For organizations handling large volumes of transactions, classified under PCI DSS Level 1, a Report on Compliance (ROC) is required. This detailed audit report verifies that your organization meets all PCI DSS Level 1 certification requirements and serves as formal proof of compliance for payment brands and acquiring banks.

Being PCI DSS compliant Level 1 demonstrates your organization’s commitment to protecting cardholder data and reducing the risk of breaches, which is critical for maintaining trust with customers and partners.

FAQ

What is the difference between a ROC and a Self-Assessment Questionnaire (SAQ)?
The ROC is a formal audit conducted by a Qualified Security Assessor (QSA) and is required for Level 1 merchants and service providers. The SAQ is a self-assessment reporting tool for smaller organizations that don’t process as many transactions.
The timeline depends on your organization’s readiness and complexity. Most organizations take 3–5 months to prepare for the audit. The audit itself is completed within several weeks.
The ROC includes a clear definition of your PCI environment, a detailed evaluation of your compliance with all 12 PCI DSS requirements, as well as findings, evidence, and validation of implemented controls.
Yes, we offer end-to-end support, from initial readiness assessments and remediation planning to conducting the formal audit and submitting the ROC.
The PCI SSC’s website features a Document Library with all the essential security guidance and documentation for merchants and service providers. To find the right SAQ for your organization, use the filter option under the search bar and select “SAQs.” If you’re unsure which SAQ applies to your business, refer to the document titled “Understanding SAQs for PCI DSS” in the library, which provides clear guidance, or talk to one of our experts.
