IoT cybersecurity: 28 billion devices to be secured by 2028 globally
Weak IoT security poses huge enterprise risks
A new report by Juniper Research has revealed that the number of Internet of Things (IoT) devices globally protected by cybersecurity solutions will soar to 28 billion by 2028, marking a significant increase from 14 billion in 2024. This growth, representing more than 100%, reflects the expanding role of IoT in everyday life and business operations.
Despite this impressive growth, the study raises concerns over the increasing complexity of IoT networks and the need for robust security frameworks. As the IoT landscape becomes more intricate, fragmented cybersecurity solutions may struggle to keep pace. Experts stress the importance of adopting unified frameworks to better manage and secure the burgeoning IoT ecosystem.
One of the most crucial solutions identified is implementing Zero-Trust Architecture (ZTA) frameworks. ZTA operates under the principle that no device, user, or network component should be automatically trusted, regardless of location or prior interactions.
This means constantly authenticating and verifying every device and user attempting to access the network. By continuously monitoring IoT devices, ZTA frameworks offer enhanced visibility, enabling faster threat detection and mitigation.
The Juniper Research report highlights that scalability will be essential as the number of IoT networks continues to rise, particularly in small and medium enterprises (SMEs) experiencing rapid digitalisation. Vendors must ensure their cybersecurity solutions are adaptable to various network sizes and configurations to effectively handle the increasing number of connected devices.
Michelle Joynson, author of the research, said: “The IoT cybersecurity market is expected to reach $51 billion by 2028, partly driven by adoption from SMEs. To capitalise on this opportunity, vendors must simplify their solutions, as IoT architectures become more complex and more diverse connectivity technologies are introduced.”
The study also reveals that weak IoT security poses significant enterprise risks, including data breaches, financial losses, and regulatory non-compliance. The urgency of fortifying IoT networks against such threats cannot be overstated, with cybersecurity becoming a critical factor in the success and sustainability of businesses worldwide.
As businesses embrace the future of IoT, the demand for effective cybersecurity solutions will only grow, and frameworks like ZTA are expected to play a key role in securing tomorrow’s connected world.
