What is a PCI DSS Assessment?

The PCI DSS framework defines the way in which customer payment card data is processed, transmitted and stored. Compliance with the standard protects your customers and you against fraud, chargebacks and significant financial penalties imposed by card issuers.

A PCI DSS assessment tests the various touchpoints in your payment workflow to ensure security provisions are working correctly. From the physical card payment terminal at the checkout to the way in which sensitive data is stripped from transaction details before storage, every factor is assessed in depth.

Why do I need a PCI DSS Assessment?


To demonstrate PCI DSS compliance

In order to achieve PCI DSS compliance, your business must maintain a cardholder data environment (CDE) that meets the specified standard. A PCI DSS assessment from Fidus independently confirms that your systems comply with all six categories specified in the standard.


To maintain PCI DSS compliance

PCI DSS compliance is an ongoing effort – the standard calls for regular testing to confirm safeguards are still adequate. Organising an annual compliance assessment with Fidus provides evidence that your business is actively working to maintain compliance.


To test security safeguards

Having security technology in place is the first step towards PCI DSS compliance – but can these safeguards be trusted? Every assessment performed by Fidus tests your systems to ensure they are providing sufficient protection for the payment data you process.


To maintain your brand reputation

Security breaches are costly and embarrassing – customers actively avoid brands that have been breached. A PCI DSS assessment offers proof that your business takes security seriously, and is determined to protect its customers against fraud.


To refine your incidence response plan

Routine testing of your security systems – including those protecting payment data – is an important aspect of your planning. Routine PCI DSS assessments will help to refine your incident response processes.

Our Approach

Complete CDE audit

The PCI DSS standard specifies six categories where your business must demonstrate suitably strong protections. Fidus consultants will test every aspect of your cardholder data environment (CDE) to ensure it meets expectations and properly protects the payment card data you have been entrusted with.

Penetration testing

To ensure your security provisions are operating correctly, Fidus consultant will carry out a range of penetration tests. These will test every point of the payment processing network, identifying vulnerabilities that require urgent attention.

Strategic planning

As your IT environment evolves, the risk of introducing new security breaches increases. Routine PCI DSS assessments ensure that these issues are identified and addressed before they can be exploited.

Cyber attack response

In the event that your CDE is compromised, our consultants are on hand to help mitigate the damage. Our PCI DSS trained engineers will help you regain control of the situation, restore operations and carry out any additional audits and remedial activities as required.
