The size of the global IoT security market is expected to increase at a Compound Annual Growth Rate (CAGR) of 18.4% from USD 24.2 billion in 2024 to USD 56.2 billion by 2029. The market for IoT security is being driven by the growth in data volume brought about by 5G. As more devices are linked and 5G networks provide faster speeds and lower latency, data traffic is growing exponentially. Because it becomes increasingly difficult to monitor, analyze, and defend against cyber attacks, such large data poses new security challenges. To solve this, strong IoT security solutions are necessary to protect private information, stop illegal access, and guarantee network integrity.

Organizations across industries experience the benefits of IoT, the complexity and vulnerability of their networks increase exponentially. For this, Providers such as IBM, Microsoft, Check Point, Fortinet, Atos offer IoT security solutions such as device authentication, data encryption, secure communication protocols, and advanced threat detection. These solutions are beneficial to prevent unauthorized access, data breaches, and other cyber attacks. Comprehensive security measures are necessary to safeguard sensitive data, protect critical infrastructure, and maintain operational resilience. The dynamic nature of the IoT landscape demands continuous adaptation and innovation in security solutions to counter evolving threats.
Based on the Services, the Professional services accounts for the highest market size during the forecast period.
Organizations increasingly rely on expert assistance for IoT asset protection Professional service providers offer comprehensive solutions, from risk assessments to ongoing monitoring, helping organizations mitigate security risks and comply with industry regulations. The demand for professional guidance in implementing and managing IoT security solutions increases because of the complexities in IoT ecosystems. The need for tailored security solutions, the intricacy of IoT systems, and the lack of in-house expertise that drive this demand. Professional services, including consulting, integration, and managed services, are crucial for organizations tackling IoT security challenges. The increasing frequency of ransomware attacks on IoT devices and concerns about critical infrastructure further highlight the need for professional services.
By region, North America accounts for the highest market size.
North America is one of the main geographic contributors to the global lot security market, even when it comes to market size. Economically strong nations like the US and Canada, the region offers the most substantial and cutting-edge technological infrastructure. One of the main factors driving the lot security market’s growth in North America is the existence of major regional players such as Microsoft, Fortinet, IBM, and others. Government agencies such as National Institute of Standards and Technology (NIST) are investigating loT security technology on a number of fronts, including protocols, security assurances, use cases, applications, and current services.

Unique Features in the IoT Security Market
IoT security must handle millions of varied devices. These range from constrained sensors with tiny memory to full Linux gateways. Security tools must adapt to hardware limits, protocols, and power constraints. Traditional IT security doesn’t scale this way.
IoT uses many protocols (MQTT, CoAP, Zigbee, BLE, LoRaWAN, Modbus). Each has different security gaps. A one-size-fits-all solution won’t work. Solutions need protocol-aware controls and visibility.
Many IoT systems process data at the edge, not in a data center. This reduces latency but increases attack surface. Security must run where the data is collected, not just in the cloud.
IoT devices often can’t be patched easily once deployed. Some lack remote update mechanisms. This forces security designs that assume unpatched devices will persist. Detection and segmentation become critical.
Major Highlights of the IoT Security Market
The IoT security market is expanding fast due to rapid IoT adoption across enterprise and consumer sectors. Connected sensors, industrial equipment, smart vehicles, and home devices increase attack surfaces. Growth is driven by regulatory pressure, high-cost breaches, and digital transformation spending.
IoT environments face diverse threats, including botnets, supply-chain attacks, firmware tampering, and lateral movement from compromised devices. New vulnerabilities emerge as devices proliferate, especially where default credentials and weak update mechanisms persist.
Key innovations include device identity and authentication, secure firmware update frameworks, behavioral anomaly detection, and edge-centric security processing. AI and ML are increasingly embedded to detect unusual device patterns. Zero trust models are becoming standard for IoT access control.
