Businesses handling cardholder data are under increasing pressure to safeguard sensitive information and maintain compliance with a variety of security standards.
One of these standards, and an essential one for any business that processes payments online, is the Payment Card Industry (PCI) Data Security Standard (DSS), writes Johannes Briel, senior IT security specialist at Galix.
To help ease the burden of this compliance, it has become increasingly important to partner with PCI DSS-compliant third-party service providers (TPSPs). This helps businesses achieve robust protection for cardholder data and enhance customer trust while reducing the complexities of compliance.
Enhancing data security and reducing compliance burden
One of the primary advantages of leveraging PCI DSS-compliant TPSPs is the ability to tap into their specialised security expertise. These providers are equipped with the necessary controls and processes to protect cardholder data, significantly reducing the risk of data breaches. By outsourcing certain functions to a compliant TPSP, businesses can alleviate the burden of implementing and maintaining stringent security measures internally.
The PCI DSS framework includes a wide range of security requirements, from network security to data encryption and access control. By partnering with a TPSP that has already achieved compliance, companies can reduce the scope of their own PCI DSS obligations. This not only streamlines the compliance process but also minimises the associated costs and complexities.
Cost efficiencies and advanced security capabilities
Achieving PCI DSS compliance independently can be resource-intensive, particularly for small to medium-sized businesses. Outsourcing to a compliant TPSP allows organisations to bypass some of the significant costs associated with maintaining in-house compliance infrastructure.
While engaging a TPSP may involve additional expenses, these costs are often offset by the reduction in compliance scope and the enhanced security measures provided by the third-party provider.
Moreover, many TPSPs offer advanced security services such as encryption, tokenisation, and secure payment processing. These capabilities are essential for protecting cardholder data, particularly in online transactions where data security is paramount. By leveraging these services, businesses can strengthen their security posture without needing to invest in developing these capabilities internally.
Key considerations when selecting a TPSP
Choosing the right PCI DSS-compliant TPSP is crucial for maximising the benefits of outsourcing. Businesses must conduct thorough due diligence to ensure that potential providers meet the necessary compliance standards. This involves reviewing the provider’s attestation of compliance, which is a formal document demonstrating their adherence to PCI DSS requirements.
It is essential to clearly define roles and responsibilities in contractual agreements. This ensures that both the business and the TPSP understand their obligations regarding data security and compliance.
With the introduction of PCI DSS version 4.0, effective from April 2025, it is even more critical for businesses to align their contracts with the latest compliance requirements. Having well-defined agreements helps prevent misunderstandings and ensures a smooth partnership.
The importance of continuous monitoring
While outsourcing certain compliance functions to a TPSP offers many benefits, businesses cannot fully relinquish responsibility for the security of cardholder data. Continuous monitoring of the TPSP’s compliance status is vital to ensure ongoing protection and adherence to security standards. This includes regular assessments of the provider’s security controls and processes to identify any potential gaps or vulnerabilities.
Engaging in periodic reviews, such as quarterly check-ins and annual compliance assessments, helps ensure that TPSPs remain compliant over time. Utilising compliance platforms or cloud-based monitoring tools can simplify the process of tracking the provider’s compliance status and security performance.
Proactive management of third-party relationships
Despite the advantages of using a PCI DSS compliant TPSP, businesses must be prepared to manage risks associated with third-party relationships. This includes having a robust plan in place for addressing any compliance issues or data breaches that may arise. Open communication with TPSPs is essential for identifying and resolving security concerns promptly.
If a TPSP falls out of compliance, businesses should take immediate steps to address the issue. This may involve working collaboratively with the provider to understand the root cause and implementing corrective actions. In cases where compliance cannot be restored, companies may need to consider alternative providers to safeguard their cardholder data.
Maximising security and compliance through strategic partnerships
Partnering with a PCI DSS-compliant TPSP can significantly enhance a business’s data security while reducing the complexity and cost of maintaining compliance. By outsourcing certain security functions to specialised providers, companies can focus on their core operations while ensuring robust protection for sensitive information.
However, it is crucial to conduct thorough due diligence, clearly define contractual responsibilities, and maintain ongoing monitoring to safeguard customer trust and meet regulatory requirements.
A proactive approach to managing third-party relationships is essential for ensuring continuous compliance and mitigating the risks associated with handling cardholder data.
