IoT Engineering Services Market - Global Industry Size, Share, Trends, Opportunity, and Forecast, 2021-2031

The Global IoT Engineering Services Market is projected to expand significantly, rising from USD 35.11 Billion in 2025 to USD 132.08 Billion by 2031, representing a CAGR of 24.71%. These services comprise the essential strategic consulting, technical development, and system integration needed to build and implement connected device ecosystems. Market growth is largely fueled by the urgent demand for industrial automation and the increasing importance of predictive maintenance in boosting operational efficiency. Additionally, the widespread rollout of 5G infrastructure serves as a major catalyst, requiring specialized engineering to handle extensive machine-type communications and complex network architectures. GSMA Intelligence reported that the enterprise segment accounted for 10.7 billion IoT connections in 2024, underscoring the massive infrastructure scale that demands robust engineering support.

Despite this strong growth trajectory, the market faces a substantial obstacle in effectively securing converged information and operational technology environments. Merging legacy systems with modern connectivity often introduces intricate vulnerabilities, leaving enterprises open to cyber threats and data breaches. This security complexity compels organizations to dedicate significant resources to defensive measures rather than innovation, often delaying project implementation. Consequently, risk-averse businesses are frequently deterred from scaling their IoT initiatives, as the focus shifts toward mitigating potential liabilities rather than expanding capabilities.

Market Drivers

The rapid advancement of Industry 4.0 and smart manufacturing initiatives is fundamentally transforming the Global IoT Engineering Services Market. As industrial enterprises shift toward fully digitized operations, there is a critical need for engineering expertise to design complex cyber-physical systems and integrate legacy machinery with modern cloud platforms. This modernization effort requires rigorous technical development to support digital twins and automated workflows, leading companies to hire external specialists for system architecture and deployment. In June 2024, Rockwell Automation’s '9th Annual State of Smart Manufacturing Report' noted that 95% of manufacturers are now using or evaluating smart manufacturing technologies, indicating a major strategic shift that drives the consumption of specialized engineering and consulting services.

Simultaneously, the growing necessity for advanced IoT security and data privacy engineering is stimulating significant market activity. The expansion of connected ecosystems introduces critical vulnerabilities, forcing organizations to adopt security-by-design architectures that protect sensitive operational data from the firmware level up to the cloud. This urgency is heightened by the increasing scale of the network; Ericsson forecasts that cellular IoT connections will reach 4.5 billion by the end of 2025. This vast connectivity landscape has led to a sharp rise in hostile activity, requiring dedicated security engineering to mitigate risks. Zscaler’s October 2024 report highlighted a 45% year-over-year increase in IoT malware attacks, emphasizing the vital role of engineering services in fortifying infrastructure against evolving cyber threats.

Market Challenges

A primary obstacle hindering the expansion of the Global IoT Engineering Services Market is the profound complexity associated with securing converged Information Technology (IT) and Operational Technology (OT) environments. As enterprises attempt to link legacy industrial systems with modern connectivity, they inadvertently create intricate vulnerabilities that are difficult to defend. This security gap forces organizations to prioritize immediate threat mitigation over strategic development, effectively stalling the deployment of new engineering projects. Instead of investing in scalable innovations, businesses are compelled to divert substantial capital and workforce hours toward establishing defensive protocols and remediation strategies.

This defensive posture is reinforced by recent industry data indicating a deteriorating threat landscape. According to ISACA, in 2024, 55 percent of surveyed cybersecurity professionals reported an increase in the number of cyberattacks compared to the previous year. This rising frequency of threats fosters a risk-averse atmosphere where decision-makers hesitate to authorize new IoT engineering initiatives for fear of compromising critical infrastructure. Consequently, the market experiences a measurable slowdown as the imperative for security overshadows the drive for digital transformation and operational scalability.

Market Trends

The integration of Edge AI and AIoT capabilities is rapidly reshaping engineering workflows by requiring processing power to be deployed directly on endpoint devices. As organizations aim to reduce latency and dependence on bandwidth, engineering teams are prioritizing the development of autonomous systems capable of executing complex inference models locally. This shift demands a robust convergence of embedded software and hardware design, ensuring that intelligence is not reliant on constant cloud connectivity. According to Zededa's May 2025 survey, 90 percent of organizations are increasing their edge AI budgets for 2025, driven by the critical need to operationalize distributed intelligence across industrial environments.

Concurrently, the focus on sustainable and energy-efficient IoT product design is compelling engineers to architect devices that minimize power consumption and extend operational lifecycles. This trend is driving the adoption of specialized low-power connectivity standards, such as Reduced Capability (RedCap) technologies, which allow engineers to balance performance with strict energy constraints. By optimizing firmware and hardware for energy efficiency, companies can significantly lower the environmental impact of their connected fleets while reducing maintenance frequency. Ericsson's June 2025 Mobility Report indicates that 34 communication service providers in 24 countries are currently investing in 5G RedCap technology, reflecting a market-wide pivot toward engineering solutions that support reduced complexity and enhanced battery performance.
