OT/IT Networking & Security
Networks, Converged.
Operations, Secured.
Industrial networks require strategic convergence planning that bridges operational technology and information technology while maintaining safety, security, and operational integrity.
At Cordant, we design comprehensive OT/IT network convergence architectures that enable secure data exchange, implement robust segmentation controls, and deploy industrial-grade security solutions that protect critical infrastructure while supporting modern operational requirements.
We cut through OT/IT complexity, delivering convergence strategies that balance connectivity requirements with security imperatives.
Our network convergence services provide secure pathways for industrial digitalisation while maintaining the isolation and safety controls that protect critical operational systems.
OT Cybersecurity Framework Implementation
Establish comprehensive cybersecurity frameworks that ensure regulatory compliance and operational security through systematic implementation of IEC 62443, NIST Cybersecurity Framework, and Australian Energy Sector Cybersecurity Framework standards.
Our framework implementation includes:
- IEC 62443 industrial automation security implementation with security level assessment and zone conditioning
- NIST Cybersecurity Framework deployment including identify, protect, detect, respond, and recover functions for OT environments
- Australian Energy Sector Cybersecurity Framework (AES CSF) compliance including threat and vulnerability management
- Risk assessment and security architecture design aligned with critical infrastructure protection requirements
- Security policy development and governance frameworks specifically tailored for operational technology environments
- Compliance monitoring and reporting implementation with automated assessment and regulatory adherence validation
Industrial Control System Security
Execute comprehensive security hardening across industrial control systems that protects SCADA systems, human-machine interfaces, and programmable logic controllers whilst maintaining operational functionality and system availability.
Our industrial security services cover:
- SCADA system security hardening including server configuration, database protection, and application security implementation
- HMI security configuration with user authentication, session management, and display system protection
- OT asset discovery and vulnerability assessment with comprehensive inventory management and risk evaluation
- Security monitoring and incident response capabilities specifically designed for operational technology environments
Network Segmentation & Isolation
Design comprehensive network segmentation architectures that enable secure convergence between operational technology and information technology networks. Our segmentation services create robust security zones that protect critical industrial systems while enabling necessary data flows for modern industrial operations.
Our network segmentation design includes:
- Purdue Model implementation with defined security zones and conduits between OT and IT networks
- Network segmentation architecture using VLANs, firewalls, and air-gap technologies for critical system isolation
- Security zone classification and data flow analysis for optimal segmentation strategy
- Remote access security design with secure jump servers and privileged access controls for OT maintenance
- Network monitoring and visibility implementation across OT/IT boundary points
- Alignment with IEC 62443, NIST, and Australian Energy Sector Cybersecurity Framework requirements
