Scope Identification

Our PCI DSS QSA team works frequently with both merchants and service providers that have suffered a data breach, and it’s only afterwards they identify that required controls have not being applied to the entirety of their payment environment.

Correctly identifying the scope of PCI DSS controls within your organisation is therefore crucial to the success of your security and compliance programme.

To provide assurance of your entire scope, our QSA team works to accurately validate your scope by analysing cardholder data flows, reviewing assets, and validating control applicability within system and network architecture.

At the end of this project, you will receive a report that outlines all identified areas of scope.

Scope Reduction

By leveraging our cross-sector and cross-industry consulting experience, our PCI DSS QSA team will identify opportunities to reduce the scope of your Cardholder Data Environment, before working with your team to advise on the application os required security controls within the reduced scope.

Our QSA team is engaged by retail brands, payment service providers, and FTSE 100 companies, to provide experienced Qualified Security Assessors that understand complex technical environments in fast-paced industries, and we pride ourselves in the provision of pragmatic, business-focussed advice to reduce scope.

Our work and expertise with the PCI DSS

The Payment Card Industry Data Security Standard (PCI DSS) was developed to enhance cardholder data security measures across the world. The PCI DSS provides a baseline for your technical and operational controls designed to protect your customer’s payment data.

The PCI DSS applies to all entities involved in payment card processing, including merchants, processors, acquirers, issuers, and service providers. The PCI DSS also applies to all other entities that store, process or transmit cardholder data.

To guide our clients through the extensive requirements of the PCI DSS, we maintain a dedicated team of PCI DSS Qualified Security Assessors (QSA). Our QSA team is engaged by retail brands, payment service providers, and FTSE 100 companies (including commercial and domestic energy), to provide experienced Qualified Security Assessors that understand complex technical environments in fast-paced industries.

Our team has vast operational experience with modern technologies, including containerised and virtualised environments, and is used to providing security advice to everybody from first line support, through to the C-Suite.

Alongside our delivery work, we frequently publish security articles, white papers, and case studies, as well as evidence for research and government.

Crucially, we believe that rationalised information assurance policies – driven by evidence and data, rather than hyperbole and fear – are the best way to improve our clients’ security capabilities.
