This Service Covers

PCI DSSRequirement 1 — Network security controls and segmentation
ISO 27001Annex A 8.22 — Segregation of networks
NIS2Article 21(2)(a) — System security

What You Get

Implementation of network segmentation to isolate the cardholder data environment (CDE) and reduce PCI DSS scope. We configure: VPC/VLAN separation between CDE and non-CDE networks, firewall rules permitting only necessary traffic, micro-segmentation for database and application tiers, jump box / bastion host for administrative access, and segmentation testing to verify isolation. Result: reduced PCI scope, lower compliance cost, and stronger security posture.

How It Works

STEP 01
Map CDE

Identify all systems in the cardholder data environment

STEP 02
Design

Architect network segmentation: VPC/VLAN boundaries, firewall rules

STEP 03
Implement

Configure segmentation, bastion hosts, and least-privilege rules

STEP 04
Validate

Segmentation penetration test proving CDE isolation

Who Needs This

  • Companies whose entire network is in PCI scope due to lack of segmentation
  • Organizations wanting to reduce PCI compliance scope and cost
  • Businesses whose PCI assessor flagged insufficient segmentation
  • Companies migrating payment systems to cloud and need proper isolation

Frequently Asked Questions

How much does segmentation reduce PCI scope?+
Dramatically. Without segmentation, your entire network is in scope. With proper segmentation, only the CDE (typically 5-10 servers) is in scope. This can reduce audit cost by 60-80%.
Can this be done in the cloud?+
Yes. We use VPCs (AWS/GCP), NSGs (Azure), and security groups for cloud segmentation. Cloud-native tools make segmentation easier and more granular than traditional on-premise networks.
What is a bastion host?+
A hardened jump box that is the only entry point to the CDE for administrators. Instead of direct access to payment servers, admins SSH/RDP through the bastion host, which logs all sessions.
How do you validate segmentation works?+
We perform a segmentation penetration test: attempt to access CDE systems from non-CDE networks. PCI DSS requires this test every 6 months (Req.11.4.5). The first test is included in this service.
Will segmentation break our existing applications?+
We map all legitimate traffic flows before making changes. Segmentation rules are designed to permit required traffic and block everything else. We test in staging before production.
