Key growth drivers include the surge in connected devices across industries manufacturing, healthcare, smart cities, mobility alongside escalating cyber-threats, rising regulatory mandates and the shift to cloud/edge computing. Among market segments, the solutions component holds the largest share (given its dominance in supporting device authentication, encryption, monitoring and analytics) and geographically, North America leads the pack thanks to mature infrastructure, high corporate and government investment and early adoption of IoT security frameworks.

United States: Recent Industry Developments

In the United States, IoT security has gained strategic prominence. The federal government and major enterprises are accelerating investment in securing connected systems used in critical infrastructure, smart manufacturing and defence. One noteworthy initiative is the development of an IoT cybersecurity labelling scheme for consumer and enterprise devices, aiming to raise the baseline security level of deployed IoT equipment. Coupled with large defence budgets and R&D funding, these factors reinforce U.S. leadership in the IoT security space.

In parallel, U.S.-based security vendors are increasingly integrating artificial intelligence (AI), machine learning (ML) and extended detection capabilities tailored for IoT/OT environments. Partnerships between cybersecurity specialists and industrial players are proliferating, enabling real-time monitoring, anomaly detection and comprehensive IoT threat management. These advances are significantly enhancing the ability of enterprises to manage and monetise IoT security as a service.

Japan: Recent Industry Developments

Japan is emerging as a strategic growth hub for IoT security amid its investments in smart cities, autonomous mobility and Industry 4.0-style manufacturing. National initiatives such as Society 5.0 and the JC-STAR IoT product security labelling scheme reflect a policy push to embed security into connected device ecosystems. Japanese firms both domestic and global partners, are deploying AI-powered threat analytics, secure device platforms and industrial IoT (IIoT) frameworks to protect large-scale smart infrastructure and transport networks.

In addition, the Japanese market is seeing increased collaboration between government, academia and private sector players to develop next-gen IoT security standards, firmware-update infrastructures and secure supply chains. These developments position Japan not just as a consumer market but as a contributor to global IoT security innovation and standards development.

Growth Forecast Projected

Looking ahead, the global IoT security market is set for sustained and robust growth. With a projected value of US$ 113.76 billion by 2033, the market will benefit from exponential growth in connected devices, deployment of 5G/6G networks, proliferation of edge computing and convergence of IT and OT security domains. Enterprises across manufacturing, energy, transportation and smart city verticals will continue to invest heavily in securing their IoT ecosystems. The shift toward subscription-based security services, managed detection & response (MDR) for IoT, and device-lifecycle security are among the trends that will drive new revenue streams and market expansion.

Research Process

The underlying analyses draw on a mix of primary interviews with industry executives, device manufacturers and service providers; secondary data from publicly-available company reports and regulatory disclosures; and in-house modelling of device-connectivity growth, threat incidence projections, vertical-specific adoption curves and region-wise expenditure patterns. Market estimates factor in regional segmentation, deployment models (cloud vs on-premises), component splits (solutions vs services), security types (network, endpoint, application, cloud) and end-user industries (manufacturing, healthcare, transport, consumer electronics). Forecasts are triangulated through three methods top-down, bottom-up and trend-based modelling to ensure robustness.

Key Segments

The global IoT security market can be segmented broadly as follows:

By Component: Solutions (e.g., device authentication, secure communication, encryption, threat analytics) and Services (e.g., consulting, integration, managed services).

By Deployment Model: Cloud-based solutions and on-premises (or hybrid) deployments. As IoT ecosystems expand, the cloud-based model is proving more scalable and cost-effective.

By Security Type: Network Security, Endpoint Security, Application Security, Cloud Security and Others (including identity access management, firmware update management).

By Organization Size: Large enterprises and small & medium enterprises (SMEs). Large enterprises dominate spend, but SMEs are catching up as IoT adoption grows.

By End-User Industry: Manufacturing, Energy & Utilities, Healthcare, Automotive & Transportation, Consumer Electronics, BFSI and Others. Manufacturing and energy/utility verticals are among the biggest adopters due to their high exposure to IoT risk.

Within these segments, the Solutions component continues to hold the largest value share (over 60% of total spend) because organisations prioritise securing devices, communications and data flows first. Vertically, manufacturing and energy & utilities are major spenders given the mission-critical nature of their operations.
