Nozomi says Arc is designed to analyse endpoint vulnerabilities, identify compromised hosts, be deployed remotely, and accelerate monitoring deployments in mission critical systems.

It is also intended to complement the network-based analysis provided by Nozomi Networks' Vantage and Guardian platforms.

Nozomi Arc is claimed to be the only OT product in the market to detect malicious hardware, and the first to provide continuous visibility into active and inactive network assets and key endpoint attributes as well as information about who is using them, thus providing more complete threat analysis and monitoring of potential attack entry points than is possible with a just a network-based sensor alone.

Nozomi says it also identifies process anomalies as well as any suspicious user activity, thus reducing the potential for insider threats or compromised hosts.

As Arc is a piece of software, it can be deployed remotely, either as part of a standard operating environment or intermittently to collect data from time to time, with no administrative overhead to manage thousands of endpoints across multiple sites, according to Nozomi.

"Operational resiliency is the top business priority for critical infrastructure organisations, which can only be achieved by lowering cyber risks and increasing security," said Nozomi Networks co-founder and chief product officer Andrea Carcano.

"Nozomi Arc accelerates time to resiliency by transforming every computer on the network into an OT security sensor. It quickly extends visibility to attack surfaces and threats inside endpoint hosts and their local network. With Nozomi Arc, users can quickly corollate more information from more sources for better diagnostics and faster time to response."
