WHY IOT SECURITY DEMANDS A NEW APPROACH


As IoT devices proliferate across critical sectors, the risks and responsibilities tied to Olly Carter, Senior Channel Sales Director at Forescout, examines how the surge in connected endpoints is transforming cyber


threat landscapes and compliance priorities, urging channel partners to reassess their strategies amid growing regulatory pressure and previously unseen vulnerabilities across operational networks.

cross industries as varied as energy, transport, government and retail, the reliance on Internet of Tings (IoT) devices


is growing exponentially. From smart meters and scanners to infusion pumps and access controls, these connected endpoints are quietly becoming the backbone of modern operations, oſten without the visibility or protection that is afforded to traditional IT infrastructure. Te numbers are staggering. According to IoT


Analytics, global IoT device volumes are expected to nearly double from 18 billion in 2024 to over 40 billion by 2030. In sectors where uptime, efficiency and automation are essential, IoT deployments have already crossed the 100 million mark. But with this growth comes a critical challenge:


security. IoT and operational technology (OT) endpoints now outnumber traditional managed IT assets by a ratio of 3 to 1. Tat imbalance is fuelling a dramatic shiſt in cyber threats, with attackers consistently seeking to bypass hardened servers and workstations to exploit the ‘soſter’ edges of the likes of badge readers, smart liſts, payment terminals and even heating, ventilation, and air conditioning (HVAC) systems. At the same time, the explosion of devices


is being met with a wave of new and updated regulations. As standards such as PCI DSS 4.0, NIS2 and other industry-specific frameworks come into force, many organisations are discovering they’re not as prepared as they thought. Compliance now extends far beyond the data
