PCI DSS Assessments

Get in Touch

With cyber threats increasingly sophisticated and prevalent it’s imperative for organisations to adhere to stringent security standards to protect sensitive financial information. One such standard that holds substantial significance is the Payment Card Industry Data Security Standard (PCI DSS). As a leader in the field of cyber security, Daisy understands the critical importance of PCI DSS compliance in safeguarding your organisation’s reputation, maintaining customer trust, and mitigating financial risks.


PCI DSS certification is a comprehensive framework established to ensure the secure handling, storage, and transmission of credit card and payment card information. Developed collaboratively by major credit card companies, PCI DSS certification is essential for businesses that handle payment card data to prevent data breaches, fraud, and unauthorised access. It encompasses a set of security requirements, including network protection, access controls, encryption, regular monitoring, and compliance reporting.

Achieving PCI DSS certification signifies an organisation’s commitment to safeguarding sensitive financial information and maintaining the trust of customers and partners in the payment card ecosystem.

PCI DSS Assessments

Through our work as Qualified Security Assessors (QSAs), our role is to:

  • Help you understand your PCI DSS compliance obligations and options
  • Support you through a development programme to deploy compliant systems, and remove others from scope
  • Assess you against the standard, either as a merchant reporting to your bank, or as a service provider

We are well placed to understand the more challenging aspects of PCI DSS and are able to create solutions that are tailored to your particular challenges, ensuring you have a smooth route to compliance. We also support customers in gaining compliance following a breach of card data.

Whether you need multiple solutions or a single solution to fill the gaps in your existing technology or expertise, our nationwide team can provide the support your business may need.

How we work

Our aim is to support any organisation to achieve PCI DSS compliance and effective cyber security. Here are a few of the ways we do this:

  • Provide expert, vendor independent, technical and security advice
  • Always seek ways to reduce the scope of compliance to minimise costs and impact
  • Offer solutions to complex problems, such as legacy systems
  • Advise on the development of policies, procedures and standards
  • Analyse complicated and varied payment systems, to identify where PCI DSS does and doesn’t apply
  • Aid in completing self-assessment questionnaires (SAQ)
  • Conduct full assessments for organisations and service providers

As with all solutions, they will be specific to the organisation and as such, we take a tailored approach to ensure you are achieving compliance and meeting your security obligations.

Have you thought about…?

Penetration Testing
A ‘point in time assessment’, providing a snapshot of your security posture at the point of testing. As new security vulnerabilities are constantly being discovered and published, both penetration testing and vulnerability assessments should be conducted regularly. Most security specialists will recommend at least annual penetration tests.

ISO 27001
An internationally recognised security framework which can be adopted by most organisations to help identify their vulnerabilities. Its flexibility means businesses can choose the most appropriate controls, commensurate with their level of risk, and provide assurances as to the protection and availability of their information.
