A new study from Juniper Research has found the global number of IoT devices protected by cybersecurity solutions will hit 28 billion by 2028, an increase on 14 billion in 2024. This represents a growth of 100% over the next four years, however the company warned that with the growing complexity of IoT networks, frameworks underpinning security solutions are becoming increasingly more important to address fragmented approaches to IoT cybersecurity.
With weak IoT security, enterprise IoT users risk events such as data breaches, financial losses, and regulatory non-compliance. To best position IoT networks against these threats, the study identified the implementation of zero-trust architecture (ZTA) frameworks as a priority. ZTA frameworks operate on the principle that no device on a network is to be inherently trusted, which requires constant authentication. These frameworks also offer greater visibility of IoT device activity through continuous authentication, enabling earlier threat detection and mitigation.
Given the scale of expected IoT growth, and rapid digitalisation by small-to-medium enterprises (SMEs), these frameworks will need to be deployed across IoT networks of different sizes. As the number of networks grow, vendors must leverage the scalability of ZTA frameworks to ensure that cybersecurity solutions keep up.
“The IoT cybersecurity market is expected to reach $51 billion by 2028; partly driven by adoption from SMEs. To capitalise, vendors must simplify their solutions in a time when IoT architectures are becoming increasingly complex, and a greater number of connectivity technologies are used,” commented Michelle Joynson, research author, Juniper Networks.
