OT/IT security, production continuity, and cyber disruption defense.
Overview
Production lines depend on vendor remote access, legacy systems, and IT/OT connectivity. An office-network foothold can become physical operational downtime.
Safety and production continuity come first. Hard segmentation, remote-access control, and recoverable backups for engineering and operations must advance together.
Hoxy coordinates OT assessment with safety constraints and maintenance windows so testing itself does not become disruption.
Common risks
- Lateral movement from IT to OT
- Production line downtime
- Industrial ransomware
Key controls
- OT zone isolation and industrial DMZ
- Vendor remote access with MFA and scheduling
- IT/OT boundary monitoring and lateral-movement alerts
- Backup and recovery for PLC/engineering and related servers
- IR drills focused on production stoppage
Compliance
- Alignment with industrial security principles, operational safety, and internal plant change requirements for OT.
