Compliance
Payment Card Industry Data Security Standard

PCI DSS

Security standard for organizations handling cardholder data.

Overview

What it is, in plain English.

PCI DSS v4.0.1 is the global standard every merchant, processor, and service provider must follow when handling cardholder data. The cost of compliance is dominated by scope — and the cost of breach is dominated by what's in scope when it happens. Lyra's PCI work is obsessively focused on minimizing your Cardholder Data Environment (CDE) through segmentation, tokenization, and architectural redesign — then implementing the 12 requirements against what's left.

PCI DSS scoping, segmentation, control implementation, and ongoing monitoring across all merchant and service-provider levels.

Who needs it

Built for organizations that have to get this right.

  • Merchants of any level (1–4) accepting card payments

  • Service providers storing, processing, or transmitting cardholder data

  • SaaS platforms whose customers transact on their infrastructure

  • Call centers, healthcare billing operations, and any business taking card-not-present payments

Our approach

How we get you audit-ready and keep you there.

We don't drop policy templates and disappear. We design controls, implement them in your environment, prepare every artifact, and walk with you through the audit — then operate the program after certification so you stay compliant year over year.

  1. 01

    Scope Reduction

    Before we implement a single control, we shrink the CDE — through tokenization, P2PE, network segmentation, and SAQ pathway selection.

  2. 02

    Gap Assessment

    We assess the in-scope environment against all 12 PCI DSS requirements and 300+ sub-requirements, with a defensible scoping diagram.

  3. 03

    Remediation & Hardening

    We implement the technical and procedural controls — segmentation firewalls, FIM, logging, access reviews, and secure development practices.

  4. 04

    QSA Support or SAQ Completion

    For Level 1 entities, we partner with a QSA and run the audit prep. For SAQ-eligible entities, we complete the SAQ and Attestation of Compliance.

Key controls

What's actually in scope.

  • Network segmentation and firewall rule governance

  • Strong cryptography for cardholder data at rest and in transit

  • Tokenization and P2PE deployments

  • File integrity monitoring and centralized log management

  • Quarterly ASV scans and annual penetration testing

  • Secure software development and change management

Deliverables

What you walk away with.

  • Scoping diagram and Cardholder Data Environment definition

  • Gap assessment and remediation plan

  • Self-Assessment Questionnaire (A, A-EP, B, B-IP, C, C-VT, D, P2PE) or QSA-delivered Report on Compliance

  • Attestation of Compliance for acquirers and brands

  • Continuous monitoring program with quarterly evidence cycles

Timeline

SAQ pathway: 8–16 weeks. Level 1 RoC: 4–9 months including QSA fieldwork.

Questions we hear

Straight answers to the real questions.

What changed in PCI DSS v4.0?
v4.0 (mandatory March 31, 2025) introduced customized approach options, expanded MFA requirements, targeted risk analyses, and tighter requirements around scripts on payment pages (Req 6.4.3 and 11.6.1).
Can we just outsource to a PCI-compliant processor?
Outsourcing reduces scope dramatically, but it does not eliminate it. Even SAQ-A merchants must protect the redirect/iframe page itself — and v4.0 has new scripting controls that catch many merchants by surprise.
Do you provide ASV scans?
We don't directly hold ASV status, but we partner with several ASVs and manage the scanning, finding remediation, and quarterly evidence on your behalf.
