Elisity Microsegmentation for Manufacturing: Zero Trust Policies for Users, Workloads, Agents and Devices

IEC 62443 calls for zones and controlled conduits on plant networks. NIST CSF 2.0 supports network segregation; defense suppliers may carry NIST SP 800-171 obligations, and NIS2 covers specified manufacturing sectors. The challenge is applying these controls without stopping production. NAC and 802.1X rollouts, controller limitations, per-cell firewalls and re-IP can stall enforcement. In Omdia research commissioned by Elisity, only 9% of organizations implementing microsegmentation have 81% or more of critical systems covered.

Download this four-page solution brief to discover:

  • How identity-based microsegmentation lets policy follow users, workloads, agents and devices instead of IP addresses or VLANs, so a controller keeps its policy wherever it plugs in
  • How passive telemetry discovers and classifies PLCs, HMIs, VFDs, robotics, safety systems and engineering workstations on supported Cisco, Juniper, Arista, HPE and Hirschmann infrastructure — no TAP, no SPAN, no active scanning and nothing installed on a validated controller
  • How to simulate every policy against real traffic first, then enforce during plant maintenance windows, and reach your first enforced policy in days to weeks rather than quarters
  • How enforcement behaves during a cloud outage: the last configuration stays in place on the network infrastructure if the plant loses its connection to the cloud
  • Six manufacturing use cases, from IEC 62443 zones and conduits to third-party integrator access — including a global industrial electronics manufacturer that avoided $18.5M+ in capital

Plant-Floor Asset Discovery

PLCs, HMIs, VFDs, robotics, safety systems and engineering workstations, found from passive network telemetry. No TAP, no SPAN and no active scanning.
Plant-Floor Asset Discovery

IEC 62443 Zones and Conduits

Organize assets into zones with Policy Groups and control the conduits between them, using identity-based policy across the network infrastructure you already own.

IT/OT Isolation and Ransomware Containment

Contain lateral movement between enterprise IT, plant networks and the OT estate. Policy is written per relationship on port and protocol, never a blanket allow.

Enforcement Through a Cloud Outage

The last configuration stays in place on the network infrastructure if the plant loses its connection to the cloud.

Third-Party and Integrator Access

Scope OEM, integrator and contractor access to the assets they support. Update group membership and policy as access requirements change.

Retiring Legacy Segmentation Cost

Reduce firewall-and-VLAN build-out with the network infrastructure and team you already have. A global industrial electronics manufacturer: $18.5M+ capital avoided.
