United States LoT Security Market (2033): NIST Tightens Product Security Requirements as Connected Devices Become Part of the Attack Surface

DataM Intelligence has released a new research report titled "IoT Security Market Size 2025-2033." The report analyzes the global IoT security market by offering, deployment, security type, organization size, end-user, and region, covering technology developments, competitive activity, and evolving security requirements.

In the U.S., IoT security is increasingly moving beyond threat detection toward security-by-design, procurement, software updates, maintenance, and end-of-life management. This shift is evident in 2026, with NIST finalizing NISTIR 8259 Revision 1 in April and releasing a June draft of SP 800-213 Revision 1 focused on cybersecurity requirements for federal IoT procurement.

Meanwhile, the FBI has highlighted the growing abuse of compromised routers and IoT devices as residential proxy infrastructure, adding further urgency to IoT security investments.

Recent Key Developments - United States & North America
NIST strengthens IoT security across the product lifecycle
In April 2026, NIST published IR 8259 Revision 1, expanding IoT cybersecurity guidance beyond product development to include security communication, maintenance, customer support and end-of-life management. This reinforces the integration of security into product engineering, procurement and lifecycle management.

Federal IoT procurement raises cybersecurity requirements
In June 2026, NIST released the initial public draft of SP 800-213 Revision 1, outlining cybersecurity requirements for IoT products acquired by the U.S. government. An August 2026 update initiative for SP 800-213A further reflects evolving IoT use cases and threats, making cybersecurity an increasingly important government purchasing criterion.

Compromised IoT devices fuel cybercrime
A March 2026 FBI FLASH reported that AVrecon-infected routers and IoT devices were used as residential proxies through SockSync. The service was believed to have compromised approximately 369,000 devices since 2020, highlighting how insecure IoT devices can become infrastructure for cybercrime.

End-of-life devices remain a security risk
The FBI has warned that unsupported routers can be exploited by malware such as TheMoon and used as proxies. This is increasing the importance of device inventories, vulnerability monitoring, patch management and replacement of end-of-life hardware.

Healthcare IoT faces stricter cybersecurity expectations
In February 2026, the FDA issued final Cybersecurity in Medical Devices guidance covering cybersecurity design, labeling and premarket submissions. Recent warnings involving connected patient monitors also highlight risks related to unauthorized access and data exposure, increasing demand for secure, maintainable and compliant medical IoT devices.

List of Key Players 2026:
Microsoft, Amazon Web Services, Inc., Google, IBM, Cisco Systems, Inc., Fortinet, Inc., Palo Alto Networks, Inc., Armis Inc., Thales and Allot are among the major companies covered in the global IoT security competitive landscape.

Other companies active across connected-device security, IoT visibility, network security, cloud security and OT security include specialized cybersecurity and technology providers serving industrial, enterprise, healthcare and critical-infrastructure environments.

Company Evaluation
The competitive landscape is moving beyond conventional endpoint and network protection.

Microsoft integrates IoT security into its broader cloud and security ecosystem, covering connected devices, edge environments and enterprise infrastructure.

Amazon Web Services provides IoT security capabilities through services such as AWS IoT Device Defender, which supports device-fleet auditing, security monitoring and anomaly detection. AWS has also announced that the Device Defender Detect feature will no longer be available to new customers from August 31, 2026, while the Audit capability remains available.

The AWS change is noteworthy because it creates a practical transition point for customers managing IoT fleets: security teams may need to reassess how they perform behavioral monitoring and anomaly detection across connected-device environments.

NEC, NTT DATA, Cisco, Palo Alto Networks, Fortinet, Armis, Claroty and other technology providers are also positioned across areas that overlap with IoT, OT, network and connected-device security.

The market is increasingly defined by the ability to provide asset visibility, device identity, vulnerability management, network segmentation, behavioral monitoring, threat detection and lifecycle security across heterogeneous device environments.

Growth Forecast Projected 2026:
The global IoT Security Market was valued at US$28.12 billion in 2024 and is projected to reach US$113.76 billion by 2033, expanding at a CAGR of 16.8% during 2025-2033, according to DataM Intelligence. North America accounted for 33% of the global IoT security market in 2024, making it the largest regional market.

Within the United States, the more immediate market opportunity is being shaped by the changing definition of what constitutes an acceptable connected product.

NIST's updated manufacturer guidance places greater emphasis on cybersecurity activities across the product lifecycle, while federal procurement guidance is increasingly focused on defining security requirements before an IoT product is acquired and connected to an information system.
