ISA/IEC 62443

Value Proposition: Why Choose AdVran for IEC 62443?

As manufacturing digitizes, the convergence of IT and OT creates new attack vectors. IEC 62443 provides the definitive framework for securing industrial automation systems, from risk assessment through implementation and maintenance.

1. Zone and Conduit Architecture

We design and manage network architectures based on IEC 62443’s zone and conduit model, creating security boundaries between industrial control systems and enterprise networks.

2. Security Level Assessment

We assess your current security level against IEC 62443’s tiered requirements (SL 1-4), identifying gaps between your current posture and target security level for each zone.

3. OT-Specific Monitoring

Our SOC monitors industrial networks with tools and techniques designed for OT protocols—Modbus, DNP3, OPC UA—detecting anomalies without disrupting production systems.

4. Patch Management for Industrial Systems

We manage the delicate balance of patching industrial systems—testing compatibility, scheduling maintenance windows, and implementing compensating controls when patches can’t be immediately applied.

5. Vendor and Integrator Security

IEC 62443 addresses the entire supply chain. We assess system integrators and component suppliers, ensuring security requirements flow through to every vendor touching your industrial environment.
