Network Segmentation and Enforcement in your Mission Critical OT/IoT Environments
The Challenges associated with Network Segmentation in OT Environments
Network segmentation and secure remote access controls help protect OT environments yet are difficult to implement due to:
Flat Networks are Often Difficult to Segment in Retrospect
Flat networks are easy to deploy but difficult to segment later. Without clear boundaries, applying security policies retroactively is complex and risky. This makes it easier for attackers to move laterally and harder to contain threats. Retrofitting segmentation often requires significant time and resources, underscoring the importance of planning for it from the start.
Network Access Controls Leave Security Gaps
Network segmentation protects devices and your network by grouping devices and dividing your environment into smaller (manageable) sections. Unfortunately, traditional Network Access Controls (NAC) projects can only readily identify enterprise devices, not IoT, OT and Industrial Internet of Things devices, making NAC implementation ineffective in OT environments.
Segmentation Policies are Prone to Error
Up until now, segmentation lacked automation making it a tedious, error-prone process that entails defining and constantly redefining policies to your unique environment.

Segmentation Recommendations Based on your OT Requirements
Armis Centrix™ for OT/IoT enables secured network segmentation implementation by discovering all assets, communication paths and access controls. It then builds virtual barriers that restrict unauthorized access to sensitive OT assets and mission critical systems. By limiting the scope of potential breaches, organizations can mitigate the risks posed by cyber threats, including ransomware attacks and data breaches.
Network Segmentation Violation with Reporting and Policies
Understand your network data and get reports on how assets within segments are communicating
Better Reporting and Policies for Segmentation Violation
With Armis you can identify device types that are not conforming to defined segmentation policies. You can also exercise risk assessment controls to generate ACLs to enable the correct segmentation of the device using existing NAC tools. With Armis, automatically push rich contextual information regarding your OT and IT environments to your existing integrated segmentation stack to streamline the management of traditionally complex solutions.
Water Utility Manages OT and IT Environments Without Affecting Sensitive Devices
Enhanced segmentation controls over OT Network Helps Secure and Protect Drinking Water for Millions of People
A major U.S. water utility needed device behavior and communication visibility in its sensitive OT network while ensuring service continuity. The OT network is managed separately from the IT network, yet both are under the same security umbrella. By deploying Armis in conjunction with Gigamon’s deep observability into network traffic, the security team achieved full visibility into the utility’s OT assets, along with deeper visibility into the traffic traversing the IT and OT networks.
