Security solutions for manufacturing & industrial control
Factory floors run PLCs and MES/SCADA systems on OPC-UA, PROFINET and Modbus, following the zones-and-conduits segmentation model set out in IEC 62443. Ransomware that reaches the plant floor doesn’t need to touch a single PLC to halt production — it only needs a live path back into the OT network from wherever operational data was last exported.
ConnexONE removes that path. Production metrics, quality data and predictive-maintenance telemetry travel out to MES, historians or cloud analytics in one direction only, so nothing on the analytics side — including a compromised laptop or SaaS platform — can reach back into the control network.
It sits cleanly inside the IEC 62443 zones-and-conduits model as a physically enforced conduit between the OT zone and the enterprise zone, giving auditors a hardware boundary to point to rather than a firewall ruleset to re-verify at every cycle.
From a single production cell to a multi-line plant, ConnexONE’s Guardian and Postman pair scales with the deployment: Guardian collects from the production network, and Postman distributes to as many downstream consumers — MES, cloud dashboards, corporate reporting — as the plant needs.
Where the plant needs more than a one-way boundary — routing, VLAN segmentation, remote access for integrators, and a default-deny firewall between cells — EdgeGate handles that layer natively, reading the same Modbus, PROFINET and OPC-UA traffic ConnexONE carries out.
Which ConnexONE product fits manufacturing and industrial control deployments?
The right fit depends on what the site needs to do — export data one-way, route and firewall a network, filter commands, monitor passively, or power edge devices. Here is how each product applies.
ConnexONE Data Diode
Direct fit for exporting production, quality and predictive-maintenance data out of the cell in one direction only, with nothing on the analytics side able to reach back in.
EdgeGate
Direct fit as the plant-floor router itself — segmentation, firewall and remote access for integrators, reading the same OPC-UA and PROFINET traffic ConnexONE carries out. See above.
ConnexGate
Direct fit where a cell needs granular command filtering rather than a full one-way boundary — allow Modbus reads, block writes, without blocking the connection outright.
ConnexSight
Feasible as a non-intrusive tap for security monitoring across the production network, giving a SOC visibility without an agent on any PLC.
VERGE
Feasible for line-side cameras, HMIs and wireless access points that need PoE and low-cost connectivity at different points on the factory floor.
