OT Segmentation

In today's industrial environments, operational technology (OT) devices like PLCs, HVAC systems, and ICS sensors are increasingly connected yet vulnerable to cyber threats. Elisity's identity-based microsegmentation platform enables manufacturing and industrial enterprises to rapidly discover and secure their OT assets using existing infrastructure - without disrupting critical operations. Our solution implements IEC 62443-compliant controls that contain threats while maintaining production uptime and achive OT Network Security

 

Challenges

Securing OT environments has become increasingly complex as manufacturing and industrial enterprises struggle to maintain visibility and control across converged IT/OT networks. Security and operations teams face significant challenges coordinating across multiple tools, managing diverse industrial control systems, and implementing effective segmentation and operational technology security without disrupting critical production processes or requiring extensive infrastructure changes.

OT Segmentation FAQ

OT environments demand OT network security and OT segmenation that won’t impact uptime. These FAQs cover how Elisity helps manufacturers and industrial teams secure legacy systems with identity-based microsegmentation.
Our operations can't afford downtime—can we segment OT networks with Elisity without disrupting production?

Yes, Elisity supports non-disruptive deployment, allowing you to use existing switches and simulate policies before enforcement. This ensures operational continuity while enhancing OT network security.

How will Elisity help us discover and monitor our OT devices?

Elisity automatically identifies and inventories all OT assets by leveraging your existing network switches. It provides real-time monitoring, classification, and detailed device insights, enabling effective OT security management.

We already use OT security tools—what additional benefit does Elisity provide?

Elisity complements OT monitoring tools by adding active enforcement through microsegmentation. It integrates existing device insights to proactively block unauthorized or suspicious network traffic.

Do we need new switches or network changes to secure OT networks with Elisity?

No, Elisity leverages your existing network infrastructure. There's no need for expensive hardware or reconfiguration, enabling simple, cost-effective OT security upgrades.
