When Kumar took over as CEO in April, his primary mandate was to break out of the $50 million revenue mark that Subex has been boxed-in for the past 3-4 years. For this, the IT services firm started building intellectual property around IoT security that it says has seen great traction. Subex foresees IoT security to be a big growth engine. “We have been tracking the IoT threat intelligence landscape and built a solution. We are taking this product not just to telcos, but to smart cities, oil and gas, connected cars, manufacturing and other sectors,” Kumar said.
