Arc Embedded is the first OT security sensor developed with OEMs to run inside industrial controllers, delivering visibility and threat detection at Purdue levels 0-1. It monitors east-west communications, process variable readings and controller logic changes to detect threats and anomalies, all while consuming minimal resources.

Due to their criticality and sensitivity, ICS security relies largely on passive network sensors that collect and inspect data flowing over Ethernet networks.
Industrial control systems at Purdue Level 1 are often connected to remote components at Level 0 through non-Ethernet communication.
Visibility into east-west traffic at Purdue Levels 1 & 0 is a black hole, including PLCs, RTUS, their inventories and their backplane communications.
Any network disruption at Purdue lower levels could directly impact production.
Arc Embedded builds on the capabilities in Nozomi Arc, the first endpoint security solution built for OT and IoT environments.
By working closely with each OEM, we’re able to adapt the core capabilities in Arc Embedded to the specifics of their controller family to collect the right data.


The Nozomi Arc Embedded sensor represents a significant advancement in industrial cybersecurity visibility, offering meticulous intelligence at the deepest levels of network infrastructure.
