They are shipped with default passwords, lack any way of being updated and employ light weight firmware, which cannot accommodate traditional endpoint security software. Industries such as manufacturing facilities or even medical IoT are prime targets for cybercriminals. A ransomware attack in these industries can cripple their functioning and result in immediate losses. Regulations, such as the EU Cyber Resilience Act, NIST IoT security guidelines, and CISA’s critical infrastructures requirements are forcing companies into compliance procurement. Behavioral analytics using AI and zero trust device identification is the solution.

In Q2 2025, Fortinet partnered with Siemens to deliver integrated IoT security for smart factories, co-developing solutions for industrial IoT protection in smart manufacturing environments. The partnership targets the convergence of IT and OT networks in modern industrial facilities where a single compromised IoT device can cascade into operational shutdown. The collaboration reflects the commercial recognition that industrial IoT security requires both IT cybersecurity expertise and deep OT operational knowledge.

By Solution, network security dominates, IAM grows fastest

Network security retained the dominant solution position in the IoT security market in 2025. It is the most universally deployed security control because it operates at the network layer without requiring agents on individual IoT devices. IoT devices cannot run security software. Network-level monitoring is therefore the only viable approach for billions of resource-constrained devices. Deep packet inspection, network traffic analysis, and machine learning-based anomaly detection at network chokepoints enable security operations teams to identify compromised devices, block command-and-control communications, and segment vulnerable devices from critical enterprise systems without touching each individual endpoint.

Identity and access management is the fastest-growing segment because zero-trust architecture adoption requires every IoT device to have a verified, manageable identity. Legacy IoT deployments used shared credentials, hardcoded passwords, and no formal identity management. Modern deployments require PKI-based certificate issuance, automated certificate rotation, and revocation capability for millions of devices. The commercial scale of this capability gap is driving investment in specialised IoT IAM platforms that automate device identity lifecycle management at the operational scale that manual processes cannot serve.

By End User, manufacturing dominates, healthcare grows fastest

Manufacturing retained the dominant end user position in the IoT security market in 2025. Manufacturing facilities deploy the highest density of OT-connected IoT devices of any industry sector. Industrial robots, CNC machines, quality sensors, SCADA systems, and predictive maintenance devices collectively create an enormous attack surface. A successful ransomware attack on a manufacturing IoT system can shut down an entire production line, creating quantifiable losses of USD millions per day. This operational risk creates strong procurement motivation that is independent of regulatory mandate.

Healthcare is the fastest-growing end user because connected medical devices are life-safety systems. Infusion pumps, patient monitors, imaging equipment, and clinical IoT devices that are compromised can directly harm patients. FDA guidance requires medical device manufacturers to address cybersecurity throughout the device lifecycle. Hospitals face regulatory penalties and accreditation risk from inadequate IoT security. These combined clinical and compliance pressures create the most urgent and fastest-growing institutional IoT security procurement environment of any industry vertical.

Growth Drivers: IoT device proliferation expanding attack surface, regulatory mandates creating compliance-driven procurement, and ransomware targeting of industrial IoT creating quantifiable financial risk motivation

IoT device proliferation is the market’s most structurally certain growth driver. Each new connected device deployed without adequate security adds to the exploitable attack surface. The commercial scale of this growth is extraordinary. Over 15 billion IoT devices are connected today. Each represents a potential entry point. Security investment that scales with deployment growth creates a structurally growing market whose revenue is directly linked to the technology adoption that IoT security vendors cannot prevent and can only defend against.

Regulatory mandates are creating non-discretionary procurement across multiple markets simultaneously. The EU Cyber Resilience Act, NIST IoT guidance, FCC IoT labelling, and sector-specific security requirements collectively mandate security investment that organisations must demonstrate regardless of discretionary budget constraints. Each regulatory deadline creates a compliance procurement wave whose commercial scale reflects the number of affected organisations and the penalty risk of non-compliance.

Restraints: Heterogeneous device landscape complexity limiting universal solution deployment, limited computational resources on constrained IoT devices, and skills shortage in OT security expertise

IoT device heterogeneity is the market’s most significant technical restraint. Connected devices span a range from industrial PLCs to consumer smartwatches with fundamentally different operating systems, communication protocols, and security capability. No single security solution addresses this full spectrum. Organisations deploying multi-vendor IoT environments must manage multiple security tools whose integration complexity creates operational overhead that limits effective coverage.

OT security expertise scarcity creates implementation quality challenges. Industrial control system security requires knowledge of both IT cybersecurity and operational technology engineering that few practitioners possess. The Fortinet-Siemens partnership reflects the commercial recognition that IT security vendors alone cannot serve industrial IoT requirements without OT domain expertise partnerships.

Opportunities: AI-native IoT security platforms, secure-by-design device manufacturing compliance, and managed IoT security services for SME market expansion

AI-native IoT security represents the most commercially differentiated capability direction. Traditional signature-based detection cannot protect IoT environments where devices cannot run security agents. AI platforms that learn normal device communication baselines and detect anomalies in real time without device-side agents are the only technically viable approach at IoT deployment scale. Vendors whose AI models achieve superior anomaly detection accuracy with lower false positive rates gain defensible competitive positions in enterprise procurement.

Managed IoT security services are creating the most commercially accessible market expansion pathway for SMEs. Small manufacturers, healthcare facilities, and retailers deploy IoT devices without dedicated security teams. Managed service providers who bundle IoT device discovery, continuous monitoring, and incident response into affordable subscription packages serve the long tail of the market whose aggregate volume substantially exceeds large enterprise procurement.
