PCI DSS Consultancy and QSA Auditing
Overview
PCI DSS compliance presents significant challenges for organisations that handle payment card data or provide services to those that do. The Payment Card Industry Data Security Standard is complex, with demanding requirements for implementation and ongoing maintenance.
Since 2007, Razorthorn has delivered PCI DSS consultancy and Qualified Security Assessor (QSA) audit services to major European organisations with complex payment environments. As one of the most prescriptive security compliance mandates, PCI DSS requires organisations to implement comprehensive policies, procedures and technical controls.
We understand that every organisation faces unique challenges. Our PCI DSS consultancy provides tailored compliance strategies that align with your business objectives and budget, guiding you through the entire compliance lifecycle from initial gap analysis to certification and ongoing maintenance.

The Razorthorn Approach to PCI DSS Consultancy
Pragmatic, Tailored Compliance Strategies
Our approach simplifies PCI DSS compliance whilst ensuring your business objectives remain at the forefront. We create compliance strategies that are minimally intrusive and cost-effective, without compromising the stringent requirements of the standard. Every organisation faces unique challenges and our consultants develop bespoke solutions aligned with your specific environment, business model and resources.
Comprehensive Compliance Project Management
We guide organisations through the entire PCI DSS compliance lifecycle:
1. Initial Assessment and Scoping
We begin by defining your PCI DSS scope, identifying all systems, networks and processes that store, process or transmit cardholder data. Proper scoping is critical for managing compliance costs and focusing security efforts appropriately.
2. Gap Analysis
Our consultants conduct thorough gap analysis comparing your current environment against PCI DSS v4.0 requirements. We identify missing controls, documentation gaps and technical vulnerabilities requiring remediation before certification.
3. Remediation Planning
We develop detailed remediation plans prioritising activities based on risk, complexity and resource requirements. Our plans provide realistic timelines, clear ownership and practical guidance for implementing required controls.
4. Implementation Support
Throughout remediation, our consultants provide hands-on support. We help implement technical controls, develop policies and procedures, establish security processes and prepare documentation required for audit.
5. Pre-Assessment Readiness Review
Before formal QSA audit, we conduct readiness reviews validating that all controls are in place, properly configured and adequately documented. This preparation ensures smooth audit processes and successful certification.
6. QSA Audit and Certification
Our Qualified Security Assessors conduct formal PCI DSS audits, validating compliance through comprehensive testing and documentation review. We produce the Report on Compliance (ROC) or validate Self-Assessment Questionnaires (SAQ) required by payment card brands.
7. Ongoing Compliance Maintenance
PCI DSS compliance is ongoing, not a one-time achievement. We provide continued support helping you maintain compliance as environments change, respond to new threats and prepare for annual revalidation.
