Compliance Service

Network Architecture Designed Around Your Compliance Framework

Whether you need to isolate a cardholder data environment, protect PHI, secure OT systems, or satisfy GDPR — we design the topology and deliver audit-ready documentation that stands up to scrutiny.

What's Included

🎯

Compliance Scope Definition & CDE Boundary Design

Define the boundaries of your compliance scope — isolating the Cardholder Data Environment, ePHI systems, or OT network — with explicit boundary documentation that satisfies auditor requirements.

🔒

VLAN Segmentation for Compliance Isolation

Design VLAN architecture that enforces compliance boundaries. Segmentation controls are documented with VLAN IDs, associated systems, and the compliance rationale for each boundary.

🔥

Firewall Rule Design & ACL Documentation

Define the access control rules between compliance zones. Firewall rules and ACL recommendations documented in a format suitable for both implementation and auditor review.

📊

Network Controls Mapping to Framework Requirements

Every network security control is mapped to specific requirements — PCI-DSS v4.0 requirements, HIPAA Security Rule sections, IEC-62443 security levels, or GDPR Article 32 measures.

📦

Evidence Package for Auditors

A structured evidence package including annotated topology diagrams, control descriptions, VLAN tables, and a network security summary — ready to hand to your QSA, auditor, or DPO.

🔄

Annual Review & Topology Validation

Compliance is not a one-time exercise. We offer annual topology reviews to validate that your network architecture remains aligned to your compliance framework as your environment evolves.

Compliance Frameworks We Cover

Network architecture requirements vary significantly between frameworks. Here's how we approach each.

FrameworkScope FocusKey Network ControlsDocumentation Needed
PCI-DSS v4.0Cardholder Data Environment (CDE) — all systems storing, processing, or transmitting cardholder dataNetwork segmentation, firewall between CDE and other networks, DMZ for public-facing systems, access control listsNetwork diagrams showing CDE boundary, firewall ruleset, segmentation test evidence, data flow diagrams
HIPAASystems handling electronic Protected Health Information (ePHI) — access and transmission controlsAccess controls (§164.312(a)), audit controls (§164.312(b)), transmission security (§164.312(e)), network boundary protectionNetwork topology showing ePHI flows, technical safeguards mapping, risk analysis documentation
IEC-62443OT/ICS/SCADA systems — industrial control and automation networks, safety systemsSecurity Zones and Conduits, zone security level assignment, boundary protection at conduit level, remote access controlsZone and conduit model, security level assignments, conduit design documentation, risk assessment
GDPRSystems processing personal data of EU/UK data subjects — appropriate technical measures under Article 32Access restriction to personal data systems, encryption in transit, network monitoring, breach detection capabilityNetwork architecture evidence for DPIA, technical measure descriptions, data flow mapping

Frequently Asked Questions

Can network segmentation reduce PCI-DSS scope?

Yes. Effective network segmentation is one of the most impactful ways to reduce PCI-DSS scope. By isolating the Cardholder Data Environment (CDE) from all other systems using strong segmentation controls — VLANs, firewalls, and ACLs — systems outside the CDE boundary can be excluded from the scope of your QSA assessment. We design segmentation specifically to achieve and document this isolation.

What network documentation do HIPAA auditors require?

HIPAA Security Rule auditors typically require evidence of access controls, network boundary documentation, and risk analysis covering ePHI data flows. This includes network topology diagrams showing where ePHI resides and how it is protected, VLAN segmentation evidence, firewall rule documentation, and a technical safeguards summary aligned to 45 CFR §164.312.

What is IEC-62443 network segmentation?

IEC-62443 is the international standard for industrial cybersecurity (OT/ICS/SCADA systems). It requires that industrial networks be divided into Security Zones based on security level requirements, with conduits controlling traffic between zones. We design the zone and conduit architecture, document the rationale for each boundary, and produce diagrams suitable for IEC-62443 compliance evidence.
