7. Armis Security
Armis specializes in agentless device security, which is vital for IoT ecosystems where many devices cannot run traditional security software. The solution automatically discovers and classifies every connected device on a network, providing full visibility and eliminating blind spots.
Its real-time threat detection helps organizations prevent unauthorized devices from connecting, thereby reducing the risk of breaches. Armis has become a popular choice for industries like healthcare, finance, and critical infrastructure because of its ability to manage unmanaged devices with minimal disruption.
6. Cisco IoT Threat Defense
Cisco’s IoT Threat Defense is part of its larger cybersecurity portfolio and leverages the company’s dominance in networking to deliver security at scale. It provides segmentation, ensuring that compromised devices do not affect the entire system. Cisco also offers advanced intrusion detection and policy enforcement to protect against IoT-specific threats.
With its strong integration into enterprise-grade networks, Cisco’s solution is highly suitable for organizations with complex IoT deployments. It is also scalable, making it relevant for small businesses as well as large multinational corporations managing thousands of devices.
5. Trend Micro IoT Security
Trend Micro’s IoT security solution is built around its expertise in endpoint and cloud security. The platform offers protection at multiple layers, including embedded device security, network traffic monitoring, and cloud-based analytics.
Its strength lies in protecting IoT devices from zero-day vulnerabilities through virtual patching, which allows businesses to address security flaws before official updates are available. Trend Micro also supports automotive IoT and smart home devices, making it a versatile solution across industries.
4. Fortinet FortiNAC for IoT
Fortinet has gained prominence in IoT security through its network access control solution known as FortiNAC. This tool provides detailed visibility into every device connecting to a network and enforces strict access policies. It uses dynamic segmentation to isolate risky devices and prevent malware from spreading.
FortiNAC is widely adopted in sectors such as higher education, smart cities, and industrial environments where large numbers of IoT devices must be securely managed. Combined with Fortinet’s firewall and security fabric, it delivers comprehensive protection.
3. Palo Alto Networks IoT Security
Palo Alto Networks has emerged as a leader in cybersecurity, and its IoT security offering reflects this expertise. The solution leverages machine learning to profile IoT devices automatically, detecting abnormal behaviors that may indicate compromise.
One of its unique advantages is its deep integration with Palo Alto’s Next-Generation Firewall, enabling automated threat prevention. The platform also provides detailed risk scoring of devices, helping businesses prioritize security measures. Its scalability and reliability make it a preferred solution for enterprises with complex IoT ecosystems.
2. Microsoft Defender for IoT
Microsoft has made significant strides in IoT security through Defender for IoT, which integrates with its broader cloud security ecosystem. The platform offers real-time threat intelligence, vulnerability management, and behavioral monitoring.
Defender for IoT is particularly effective in protecting operational technology environments like factories and power grids. It provides hybrid deployment options, allowing organizations to secure both on-premises and cloud-connected IoT devices. With Microsoft’s global presence and support infrastructure, it has become one of the most trusted solutions for IoT security.
1. AWS IoT Device Defender
Amazon Web Services (AWS) leads the IoT security landscape with its IoT Device Defender. As the world’s largest cloud provider, AWS has tailored this solution to protect billions of devices that rely on its infrastructure. Device Defender provides features such as device authentication, access control, and continuous monitoring of IoT configurations.
Its standout feature is anomaly detection powered by machine learning, which can identify unusual traffic patterns or behaviors that suggest an attack. AWS also allows businesses to implement policies at scale, ensuring consistent security across global IoT deployments. Given its scalability, integration with AWS cloud services, and advanced threat prevention, AWS IoT Device Defender stands as the top IoT security solution in 2025.
Conclusion
The rapid growth of IoT has expanded opportunities but also introduced new vulnerabilities. From Zscaler’s zero trust framework to AWS’s machine learning-powered device protection, each solution plays a unique role in securing the interconnected world. Organizations must carefully assess their industry needs, device types, and regulatory requirements when choosing a security solution.
