Micro-Segmentation

Attackers who get in cannot reach everything.

A flat network gives attackers free movement once they are inside. Micro-segmentation divides your network into isolated zones so a compromised device or account cannot move laterally to your most sensitive systems across your UK business.

What We Deliver

Micro-segmentation capabilities.

Network Isolation by Workload

Your network divided into isolated segments based on workload type, sensitivity, and business function. Finance systems, HR data, and operational tools each in their own segment with no cross-access by default.

East-West Traffic Control

Traffic between internal systems controlled and inspected, not just traffic entering and leaving the network. Lateral movement between segments requires explicit policy approval. No free movement inside the perimeter.

Least-Privilege Segment Access

Users and devices granted access only to the segments they need for their role. Access reviewed regularly and revoked when no longer required. Temporary access granted with automatic expiry.

Software-Defined Perimeters

Perimeters defined in software, not hardware. Segments adjusted as your business changes without physical network reconfiguration. New workloads placed in appropriate segments from day one.

Breach Containment Policies

If a device or account is compromised, the blast radius is limited to the segment it belongs to. Automatic isolation policies triggered when anomalous behaviour is detected within a segment.

Compliance-Aligned Segmentation

Segmentation architecture aligned to ISO 27001, Cyber Essentials Plus, and PCI DSS requirements. Audit evidence produced showing network isolation controls. Compliance reporting available on demand.

How It Works

From flat network to isolated segments.

01

Network Topology Mapping

We map your current network topology, identify all workloads, data flows, and trust relationships. Document where implicit east-west trust exists and which systems can currently reach each other.

02

Segmentation Architecture Design

Segmentation architecture designed based on your workloads, compliance requirements, and risk profile. Segments defined by business function. Access policies drafted for each segment boundary.

03

Policy Validation and Testing

Segmentation policies tested in a staging environment before production deployment. All legitimate traffic flows validated. No business-critical communication paths broken during rollout.

04

Phased Production Deployment

Segmentation deployed in phases starting with the highest-risk workloads. Each phase monitored for unexpected traffic blocks. Policies refined before the next phase begins.

05

Monitoring and Alerting Configuration

Monitoring configured to detect attempted lateral movement between segments. Alerts set for policy violations. Automated isolation triggered for confirmed breach activity.

06

Ongoing Policy Management

Segmentation policies reviewed quarterly and updated as your network changes. New workloads assessed and placed in appropriate segments. Annual penetration test validates segmentation effectiveness.

UK Case Studies

Segmentation deployed across the UK.

Manufacturing Business, Sheffield

Challenge: A Sheffield manufacturer had operational technology and IT systems on the same flat network. A ransomware attack on a workstation spread to production control systems and halted the factory floor for three days.

Outcome: Micro-segmentation deployed separating OT and IT networks. Production systems isolated from corporate network. A subsequent phishing attack was contained to a single workstation with no production impact.

Retail Group, Bristol

Challenge: A Bristol retail group with 14 stores needed to prevent a compromise at one store from spreading to the central systems holding customer payment data and staff records.

Outcome: Each store network segmented from central systems. Payment processing isolated from general store traffic. PCI DSS compliance achieved. A card skimming incident at one store had zero impact on other locations.

NHS-Contracted Provider, Newcastle

Challenge: A Newcastle healthcare provider needed to demonstrate network segmentation controls to pass an NHS data security assessment. Their flat network gave all staff access to all clinical systems.

Outcome: Clinical systems segmented from administrative network. Access policies aligned to staff roles. NHS data security assessment passed. Patient data access restricted to clinical staff only.

Get Started

Stop lateral movement before it reaches your critical systems.

We map your current network, design a segmentation architecture that fits your workloads, and deploy it without disrupting your business. Free assessment for UK businesses, no obligation.
