Can you store PCI Data in Zendesk?

Zendesk is not PCI-compliant straight out of the box.

For businesses using Zendesk, storing PCI data is permissible under certain conditions that align with PCI Data Security Standards (PCI DSS).

To comply with these standards, any stored cardholder data must be secured through robust security practices.

According to PCI guidelines, entities such as merchants can store cardholder names, primary account numbers (PAN), service codes, and expiration dates if there's a clear business necessity and the data can be adequately protected.

For users of Zendesk, this means implementing stringent security measures such as encryption and other forms of data protection.

Specifically, adherence to PCI DSS Requirement 3.4 is crucial, which mandates that sensitive data be protected using strong cryptography and truncation methods. This ensures that any cardholder data handled within Zendesk is not only stored securely but also safeguarded against unauthorized access and breaches.

Businesses must carefully evaluate their data storage strategies to ensure they meet these essential security requirements.

Can PCI data be leaked from Zendesk?

The risk of PCI data leakage from Zendesk, as with any platform, hinges on several factors including the security measures in place, user compliance with those measures, and the potential vulnerabilities of the system.

Zendesk users must ensure that sensitive authentication data, particularly from the magnetic stripe or chip, is never stored after authorization. Compliance with PCI DSS's strict guidelines on storage and handling of cardholder data minimizes the risk of data breaches.

However, absolute security cannot be guaranteed, making ongoing vigilance and adherence to security practices essential.

What are the New PCI 4.0 Requirements for PCI Data in Zendesk?

PCI DSS 4.0 introduces stringent requirements that significantly impact the storage and handling of PCI data on platforms like Zendesk. Below are the crucial updates and their implications for Zendesk users:

1. No Unauthorized Copy/Relocation of PAN

Requirement 3.4.2 aims to protect the Primary Account Number (PAN) from unauthorized copying or relocation. This is critical on platforms like Zendesk where customer support interactions might involve sensitive data.

The updated mandate requires strict technical controls to limit the ability to copy or move PAN exclusively to personnel who have explicit, documented authorization and a legitimate business need. This is vital in customer service environments managed through Zendesk, as they can potentially expose sensitive information if not adequately controlled.

2. PAN Must Be Unreadable

Under Requirement, PAN must be made unreadable in all storage contexts, which includes databases and logs within Zendesk's infrastructure.

The goal is to improve data security by employing keyed cryptographic hashes of the entire PAN, underpinned by stringent key management practices as dictated by PCI DSS Requirements 3.6 and 3.7.

This ensures that PAN data remains encrypted and unreadable, thereby safeguarding it from unauthorized exposure and breaches in a platform as accessible as Zendesk.

3. Incident Response for PAN Data Leaks

Requirement 12.10.7 requires robust incident response strategies ready to activate upon detecting PAN in any unauthorized areas, including platforms like Zendesk.

The focus is on quickly addressing potential data leaks by analyzing, recovering, and securely deleting or moving the PAN to a secured environment. This highlights the need for ongoing monitoring and immediate response mechanisms within Zendesk.

4. Protecting Payment Information on Zendesk

Organizations should minimize the storage of cardholder data. Essential measures to protect PCI data in Zendesk include:

  • Ensuring that customer service terminals or chat interfaces do not retain payment card data after processing.
  • Obscuring or truncating printed payment card information on any service receipts to safeguard cardholder data.
  • Keeping servers and data storage devices secure, locked, and access-controlled, particularly within customer support platforms like Zendesk.
  • Implementing strict access controls to restrict unauthorized access to stored cardholder data.

These practices collectively help secure sensitive cardholder information handled through Zendesk, addressing both digital and physical security concerns.

To maintain compliance with PCI DSS 4.0, entities using Zendesk must critically evaluate and upgrade their configurations and operational practices regularly.

This includes continuous audits to verify alignment with PCI DSS 4.0's enhanced requirements, particularly focusing on encryption validation, access controls, and logging mechanisms.
