Manufacturing Network Segmentation with Industrial Microsegmentation

Digital transformation has dramatically shifted the security landscape for manufacturers as previously isolated operational technology (OT) environments connect with information technology (IT) networks. Elisity's identity-based microsegmentation greatly improves cybersecurity for industrial control systems,  so manufacturers can secure their converged infrastructure, prevent lateral movement attacks, and maintain operational continuity while achieving IEC 62443 compliance without production disruption.

Challenges

Manufacturing organizations face mounting security challenges as legacy industrial systems become connected to enterprise networks. Traditional ICS network segmentation approaches struggle to protect these complex environments without disrupting critical production processes or requiring expensive infrastructure upgrades.

Network Segmentation Without Compromise

Transform network security with identity-based microsegmentation that enables Zero Trust in weeks, not years.

Challenge

Expanded Attack Surface

Digital transformation has connected previously air-gapped OT environments with enterprise networks, creating new attack vectors that cybercriminals exploit to gain unauthorized access to critical industrial systems.

Elisity's Solution

Comprehensive OT/IT Visibility

Elisity IdentityGraph™ transforms your switches into data sensors that automatically discover and classify all connected devices—including PLCs, RTUs, IoT sensors, and industrial equipment—providing complete visibility across your entire manufacturing environment.

Challenge

Legacy Device Vulnerabilities

Industrial control systems (ICS) manufactured decades ago without security in mind lack necessary protections and cannot be readily updated, patched, or secured with traditional endpoint solutions.

Elisity's Solution

IEC 62443 Zone and Conduit Implementation

Easily create security zones and conduits as required by IEC 62443 through policy groups that logically segment your industrial environment without complex VLAN configurations or network architecture changes.

Challenge

Compliance Complexity

Meeting stringent IEC 62443 requirements and defining proper zones and conduits becomes increasingly difficult with traditional network segmentation approaches that require complex VLAN configurations.

Elisity's Solution

Zero-Disruption Deployment

Deploy ICS microsegmentation using your existing network infrastructure without requiring new hardware, device agents, or production downtime—maintaining continuous operations critical to manufacturing environments.

Challenge

Operational Continuity

Manufacturing organizations cannot tolerate production downtime or disruption that traditional security implementations often require, creating resistance to implementing proper security controls.

Manufacturing Network Segmentation FAQ

Learn how to segment your converged IT/OT environment without risking downtime. These FAQs cover how Elisity helps industrial organizations meet security and compliance needs without halting production with Industrial microsegmentation..

How can we segment our OT/industrial network without costly downtime or new hardware?

Elisity’s agentless microsegmentation works with your current switches and infrastructure, so you can secure factory networks without ripping and replacing anything. The solution deploys quickly and transparently, ensuring production keeps running while you put security controls in place.

Our factories have PLCs and other controllers that can’t run security software. How do we protect these devices from cyber threats?

Elisity identifies each OT device on the network by its unique identity and restricts its communication to only the known-good protocols and endpoints it needs. This containment strategy isolates vulnerable controllers from unauthorized access and malware, compensating for their lack of built-in security.

IEC 62443 segmentation (zones and conduits) is complex with VLANs. Can Elisity help implement these controls more easily?

Yes, Elisity lets you define logical security zones and conduits through policy groups rather than complicated network redesigns. It essentially maps your industrial processes into segmented groups on the network, helping you meet IEC 62443 requirements without rewiring your plant.

Will implementing microsegmentation disrupt manufacturing operations or require downtime?

No, Elisity is designed for zero-disruption deployment. You can introduce microsegmentation
