Air-Gapped Governance for Operational Technology
Industrial control systems, SCADA networks, and manufacturing processes were built for reliability — not cybersecurity. As IT/OT convergence accelerates, these systems face threats they were never designed to withstand.
OT / Cyber Security
If your IT network can reach your OT network, so can an attacker. The only real air gap is a physical one — not a firewall rule, not a VLAN, not a DMZ. Firevault Control enforces physical IT/OT separation at the hardware level.

OT environments are increasingly exposed.
IT/OT Convergence
Shared connectivity between IT and OT networks exposes industrial systems to IT-borne threats.
Legacy Systems
Legacy OT systems lack authentication and encryption, and patching requires downtime.
Configuration Tampering
Attackers alter PLC programs and SCADA configurations with changes that go undetected for weeks.
The Scenario
Scenario: Ransomware Crosses IT into OT
A manufacturing plant's IT network is compromised through a phishing email targeting the finance team. The ransomware spreads laterally across the corporate network within 4 hours. Because the historian server bridges IT and OT — sharing a network path for reporting — the ransomware reaches the OT network by hour 6. PLC configurations are encrypted, SCADA displays go dark, and the plant loses supervisory control of three production lines. Recovery takes 18 days because backup PLC configurations were stored on a network-attached share — also encrypted. With Firevault Control, the Isolate module physically disconnects OT backup data from IT networks. The Transfer module governs any data movement between zones through policy-controlled windows. The ransomware reaches IT but cannot cross a connection that physically does not exist.
"We had a firewall between IT and OT. We thought that was an air gap. When the ransomware jumped across, we realised a firewall rule is just software — and software can be bypassed. We needed physical disconnection."
Hardware-enforced IT/OT separation.
OT environments gain hardware-enforced separation from IT networks without requiring changes to existing industrial infrastructure. SCADA configurations, PLC programs, and process data are protected in offline vaults, ensuring rapid recovery from any compromise and maintaining 24/7 operational continuity.
- Physical IT/OT segmentation enforcing true air-gap separation
- Configuration protection for SCADA, PLC programs, and recipes in offline vaults
- Controlled access windows for time-bound maintenance and updates
- Out-of-band management with dedicated cellular connectivity
- Historian data protection against ransomware
- Immutable audit trail for safety compliance and regulatory evidence
Isolate — Physical IT/OT Separation
Module 1 of 4Enforces hardware-level disconnection between IT and OT network zones. No shared network path exists between corporate systems and industrial control infrastructure. SCADA configurations, PLC programs, and historian data are physically unreachable from IT-borne threats — regardless of what malware, credentials, or zero-days an attacker possesses.
Key Capabilities
PLC & SCADA Config Protection
Golden copies of PLC programs, SCADA configurations, and HMI settings stored in hardware-encrypted offline vaults — immune to network-based attacks.
Historian Backup
Process historian data protected in physically disconnected storage, ensuring operational records survive ransomware and are available for safety investigations.
Controlled Maintenance Windows
Time-bound access windows for firmware updates and configuration changes — physical paths open only during authorised periods with full audit trails.
IEC 62443 Evidence
Automated compliance logging maps to IEC 62443 zone and conduit requirements — demonstrable physical separation, not just logical segmentation.
Zero-Downtime Deployment
Deploys alongside existing OT infrastructure without requiring changes to PLCs, SCADA systems, or network architecture — no production disruption.
