California-based Nozomi Networks has introduced a wireless spectrum sensor purpose-built for OT and IoT environments worldwide.

The Guardian Air provides visibility into wirelessly enabled devices which until now were only detected once connected to the wired network. It monitors several prominent wireless frequencies, not just Bluetooth and wifi, to provide security teams with immediate visibility of connected sensors, devices, laptops and mobile phones.

With 80 per cent of new IoT deployments wirelessly connected, wireless is quickly becoming a preferred network. The explosion of wirelessly connected devices increases potential access points and exploitation of networks. This puts critical infrastructure at risk of cyber attacks and disruptions to operations.

“Nozomi Networks has once again innovated to address an unmet need for wireless-level monitoring in OT and IoT environments,” said Danielle VanZandt, industry manager for commercial and public security research at Frost & Sullivan. “From smart manufacturing to digital medicine, to building automation, to modern oil field production and more, today industrial organisations are relying on billions of wireless devices to speed production and time to market. Guardian Air gives IT security professionals and OT operators the visibility they need to get a firm handle on wireless risk management and response.”

With Guardian Air, IT security professionals and OT operators can continuously monitor prominent wireless frequency technologies used in OT and IoT environments including Bluetooth, wifi, cellular, LoRaWan, Zigbee, GPS, drone RF protocols and WirelessHart. They can immediately detect wirelessly connected assets and gain asset information to address unauthorised installations. And they can detect wireless-specific threats, including brute force attacks, spoofing and bluejacking, with the added ability to determine the location of the devices performing the attacks,

This product seamlessly integrates wireless data into a single OT and IoT security platform that unifies asset visibility from the endpoint and across wired and wireless networks.

“Wireless is fundamentally changing the way industrial organisations operate,” said Nozomi Networks chief product officer Andrea Carcano. “Unfortunately, it also massively expands the potential attack surface. Guardian Air solves this problem by giving customers the accurate visibility they need at the wireless level to minimise risk while maximising resiliency. Because Guardian Air integrates easily into the Nozomi Networks Vantage platform, customers can combine network, endpoint and wireless for the greatest visibility, threat detection and AI-powered analysis for real-time security management and remediation across the entire attack surface.”

The Guardian Air (www.nozominetworks.com/products/guardian-air) wireless sensor will be available this spring from Nozomi Networks and its global network of channel partners.
