Industrial Automation Connectivity
Managed connectivity for operational technology environments
IT/OT convergence creates new exposure
Industrial automation is converging with IT infrastructure, and the security frameworks are catching up. IEC 62443 requires zones, conduits, and defined security levels. NIS2 covers manufacturers with 50 or more employees. The EU Cyber Resilience Act applies to every connected device. Managing this across distributed OT environments with legacy equipment is a significant operational challenge.
- IEC 62443 mandates network zones, conduits, and security levels for industrial control systems
- NIS2 obligations apply to manufacturers and operators with 50+ employees
- EU CRA applies to every connected device in the OT environment
- Legacy OT equipment was never designed for network security
- IT and OT traffic sharing the same network creates lateral movement risk
Network architecture that maps to IEC 62443
SIMSY provides the network segmentation, isolation, and audit capabilities that IEC 62443, NIS2, and CRA require, delivered at the cellular layer without changes to existing OT equipment.
- CPL creates IEC 62443-compliant zones and conduits at the cellular network level
- Multi-APN segregates OT and IT traffic on a single SIM, no additional hardware
- No public internet exposure, OT management stays entirely on private infrastructure
- Network-native data collection via SNMP and Modbus over IP without installing agents
- Remote access to OT environments without exposing control systems to the internet
- Automated audit trail generation for IEC 62443, NIS2, and CRA compliance
What the platform delivers
Network Segmentation via CPL
Cellular Private LAN creates the zones and conduits that IEC 62443 requires. Each zone is isolated at the network level with defined security boundaries, no changes needed to existing OT equipment.
Multi-APN OT/IT Segregation
Run OT management traffic and IT traffic on completely isolated logical networks using a single SIM. No shared network paths between control systems and corporate infrastructure.
Private OT Management
All OT management traffic stays on private infrastructure. No public internet exposure means no publicly routable attack surface for your industrial control systems.
Network-Native Data Collection
Collect telemetry from OT devices via SNMP and Modbus over IP without installing agents on control systems. Monitor device health and performance without modifying the OT stack.
Secure Remote Access
Access OT environments remotely for diagnostics and troubleshooting without exposing control systems to the public internet. Engineers can reach equipment without being on site.
Compliance Evidence
Automated audit trail generation covering IEC 62443 zone documentation, NIS2 network security requirements, and CRA device security obligations. Compliance evidence without manual effort.
