In a world where billions of devices now shape our connected reality, IoT security has evolved from an IT problem to a board-level priority. As the iot ecosystem grows—an interconnected network of devices, systems, and infrastructures—comprehensive iot security solutions have become essential to protect, manage, and scale these environments. Yet despite the growing awareness, one challenge remains stubbornly persistent — the management and protection of unmanaged devices. These devices, often invisible to traditional IT systems, create blind spots that attackers exploit with increasing precision.

As the Internet of Things (IoT) continues to expand across industries, risk management has become one of the most pressing challenges for security and compliance leaders. The convergence of AI and IoT (ai iot) is accelerating this transformation, introducing new opportunities but also creating a more complex risk landscape that requires advanced approaches to risk management. With billions of devices now interconnected — from industrial sensors and medical devices to vehicles and energy systems — cyber physical systems form the backbone of modern IoT deployments, further increasing the potential attack surface and vulnerability to cyber threats.

In 2025, machine identities outnumber human identities by a factor of 40 to 1. Every connected sensor, gateway, vehicle, and robot depends on a digital credential to prove its authenticity and secure its data. These digital credentials serve as unique identifiers for devices, enabling secure communications and access control.

In 2025, digital transformation has pushed operational technology (OT) and information technology (IT) closer than ever before. Manufacturing plants, hospitals, smart cities, and energy grids now depend on billions of connected devices — yet this connectivity has brought a complex new security challenge: maintaining visibility and control across every asset. The proliferation of many IoT devices within these environments complicates visibility and control, as organizations must now manage and secure an ever-growing number of endpoints.

For many organisations, cybersecurity is viewed as a cost of doing business — a necessary but difficult-to-quantify expense. However, the initial investment required for IoT security is substantial and essential for achieving long-term value, innovation, and competitive advantage. Yet in the world of connected devices, security is not just a cost centre; it’s a measurable investment in resilience, efficiency, and compliance.

Across every industry, compliance has become inseparable from cybersecurity. Governments and regulators are tightening the rules around how connected devices must be secured, authenticated, and monitored throughout their lifecycle. For enterprises with thousands—or millions—of Internet-of-Things (IoT) and Operational-Technology (OT) devices, and in some cases even millions, manual compliance is no longer sustainable. Automation is now essential.

In the evolving world of cybersecurity, one principle now dominates every executive discussion: Zero Trust. The concept — “never trust, always verify” — has become the defining framework for protecting modern digital ecosystems. Yet even the most sophisticated Zero Trust strategies can collapse when one critical factor is overlooked: unmanaged devices.
