CMMC for Legacy Systems: Securing Manufacturing and OT Environments Without Downtime

Recorded January 2026

Many manufacturers and defense suppliers are being asked to meet CMMC requirements with environments that were never designed for modern cybersecurity controls. Legacy equipment, flat networks and strict uptime constraints make cloud-first or rip-and-replace approaches unrealistic.

In this webinar we break down the real challenges of CMMC in legacy and industrial environments and show how a modern, on-premise security enclave is deployed without downtime or network redesign, with a live demo and questions from the field. For IT managers, security leaders and compliance teams in manufacturing, defense and critical infrastructure.

What you will learn

  • Why CMMC is especially hard in manufacturing and OT environments
  • Where traditional VLAN-based segmentation falls short for compliance
  • How to apply Zero Trust principles on-premise, around legacy assets
  • A live demo of a practical, deployable approach (from 21:21)
  • Answers to common CMMC and legacy-system questions from the field (from 47:01)
