Industrial Network Security
We review and strengthen the networks that connect your industrial systems, checking segmentation, remote access and traffic flows between IT and OT, so a problem in one area cannot spread across your operation.
We review how your industrial networks are built and defended
Flat industrial networks let an attacker move from a single foothold to your most critical controllers with little to stop them. We review how your network is divided, how IT and OT connect, and where traffic flows, then help you build boundaries that contain a problem instead of spreading it.
Network Segmentation
How your environment is split into zones and conduits, and where those divisions break down.
IT/OT Boundary
The firewalls, gateways and DMZs that sit between your corporate and operational networks.
Remote Access
Vendor connections, VPNs and jump hosts that reach into the industrial environment.
Traffic Visibility
Whether you can see and monitor the traffic moving across your OT network.
Network Devices
Switches, routers and gateways carrying industrial traffic that often go unmanaged and unpatched.
Containment Design
How well your network limits lateral movement once an attacker is inside.
A Flat Network Turns a Small Foothold Into a Full Compromise.
In many plants the network grew organically, one connection at a time, until IT and OT sat on the same flat space with little between them. That makes life easy for operators and just as easy for an attacker. Once inside, they can move sideways from an office laptop to a critical controller with almost nothing standing in the way.
We map how your industrial network is really built, not how the diagram says it should be, and we find the paths that let a problem spread. Our team works with your staff to design segmentation, secure the IT/OT boundary and lock down remote access in a way that holds up in practice. You get a network that contains incidents and gives you the visibility to catch them early.
Standards and Frameworks We Work To
- We apply the IEC 62443 zone and conduit model to structure segmentation around clear security levels and controlled connections.
- Our recommendations draw on the Purdue Enterprise Reference Architecture and NIST SP 800-82 to define sensible boundaries between IT and OT.
- Where remote access and monitoring must meet regulatory expectations, we align the design to the obligations your sector carries.
Aligned to the frameworks that matter
Our testing follows the methodologies that set the global standard for application security.
