Gartner Critical Capabilities for Enterprise LAN: What Networks Need Today   Read >>

Mapping Zero Trust to PCI DSS 4.0

For IT teams managing Cardholder Data Environments (CDE), the operational burden of PCI DSS is not just implementing network segmentation and firewall rules, but maintaining continuous compliance and constantly proving adherence during audits.

Nile’s whitepaper reveals why legacy networks leave cardholder data exposed. And how a redesigned architecture solves this by natively enforcing Zero Trust micro-segmentation and eliminating risk, to continuously enforce PCI audit readiness.

Today’s Reality

Legacy Reliance: Outdated networks cannot support today’s security or compliance demands

VLAN Limitations: Legacy VLAN make PCI-mandated compliance virtually impossible

Network-Wide Liability: Payment systems mixed with general traffic make compliance costly

Strategic Shift: Built-in Zero Trust must automatically satisfy evolving mandates

Securing Cardholder Data requires continuous verification. Moving to Zero Trust ensures continuous enforcement, strict network segmentation, and explicit least-privilege access—vital to maintaining compliance.

What’s inside the paper

  • Explanation of built-in deny-by-default and segment of 1 isolation features
  • A clear definition of where network modernization can protect information systems
  • The value of a network delivered as-a-service, designed for complex use cases
