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- Vendor equipment with outdated firmware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
Phase 1: OT Discovery & Risk Assessment
2 monthsComprehensive inventory of OT assets and risk assessment. Identified critical systems requiring air-gap protection.
Phase 2: Network Segmentation Design
2 monthsDesigned multi-layer network segmentation with industrial DMZ and Purdue Model implementation.
Phase 3: Phased Implementation
6 monthsImplemented segmentation during planned maintenance windows. Air-gapped critical manufacturing systems.
Phase 4: Monitoring & Response
2 monthsDeployed OT-specific monitoring and anomaly detection with 24/7 SOC integration.
