Secure Architecture Design
We translate ISA/IEC 62443 zone-and-conduit principles into buildable network and system architectures — coordinated with IT, engineering, and operations so the resulting design is realistic to install and maintain.
/ What's included
Scope of work
Reference architectures for OT networks — zones, conduits, DMZs, and remote access — drawn from ISA/IEC 62443 and NIST patterns.
Helps with: greenfield OT designs, segmentation plans, integrator-ready drawings.
- Zone-and-conduit modeling with security level targets
- Industrial DMZ, jump-host, and remote-access design
- Switch, router, and firewall topology drawings
- Authentication, logging, and monitoring strategy
- Coordination with IT security and engineering of record
/ Where this fits
Typical use cases.
- 01OT reference architecture for a new treatment plant
- 02Multi-site SCADA architecture for a regional utility
- 03Modernization roadmap for a legacy flat network
