Overview

Operational technology security assessment and network segmentation for critical manufacturing infrastructure without disrupting production.

The Challenge

Legacy operational technology systems were connected to corporate networks, creating significant risk to critical manufacturing operations. The organization needed security improvements without any production downtime.

  • Legacy OT systems with no security controls
  • Flat network connecting IT and OT environments
  • Zero tolerance for production downtime
  • Limited visibility into OT network traffic
  • Vendor equipment with outdated firmware

Our Solution

We designed and implemented comprehensive OT security with network segmentation, monitoring, and air-gapped critical systems while maintaining 99.9% uptime.

Implementation Approach

1

Phase 1: OT Discovery & Risk Assessment

2 months

Comprehensive inventory of OT assets and risk assessment. Identified critical systems requiring air-gap protection.

2

Phase 2: Network Segmentation Design

2 months

Designed multi-layer network segmentation with industrial DMZ and Purdue Model implementation.

3

Phase 3: Phased Implementation

6 months

Implemented segmentation during planned maintenance windows. Air-gapped critical manufacturing systems.

4

Phase 4: Monitoring & Response

2 months

Deployed OT-specific monitoring and anomaly detection with 24/7 SOC integration.
