OT Security Firm Claroty Expands IoT Tracking Focus Scope

A promotional blurb on cybersecurity security startup Claroty’s website boasts the firm is fluent in industrial protocols. “We were born and raised in the world of Modbus, Profibus and DeviceNet.” It continues: “We think in S7 and dream in DNP3. We go beyond Ethernet/IP into the realms of the most arcane Fieldbus and serial protocols.” Now, it is adding IoT devices to that list, defining “Internet of Things” as a sort of umbrella term for nontraditional networked devices. “Put me in the camp of someone who thinks ‘IoT’ is used way too cavalierly,” said Dave Weinstein, chief security officer at Claroty. “What we mean by IoT, with respect to operational technology networks, is basically everything else — everything other than an OT device or something that’s clearly a traditional [networked] IT device.” The latest version of Claroty’s Continuous Threat Detection OT securitysoftware, release 3.5, is designed to enhance network visibility to include such IoT miscellany. The software also includes new functionality to help security professionals deal with false alarms.
