The absence of a universal interoperability stack increases integration timelines and inflates the total cost of ownership. Vendor lock-in also deters migration toward best-in-class solutions, muting competitive pressure. Standards bodies have yet to align on encryption key-rotation or secure-boot specifications, leaving security teams to craft custom bridges. These gaps temper the otherwise rapid expansion of the IoT infrastructure security market.

Shortage of IoT-Focused Cybersecurity Talent

Global cybersecurity vacancies reached 4.8 million professionals in 2024, and roles requiring embedded-system skills remain the hardest to fill. U.S. enterprises report a 28% vacancy rate for IoT-security positions, with average time-to-hire stretching to eight months. Skills scarcity pushes organizations toward managed services and forces vendors to enhance automation, yet implementation schedules still slip, delaying revenue realization. While technology can mitigate some gaps, human expertise remains indispensable for incident response and architecture design, moderating near-term growth momentum.
