IoT devices now outnumber traditional endpoints in most enterprise environments. From printers and cameras to medical equipment and building systems, these devices enable automation and efficiency — but they also expand the attack surface in ways traditional security tools were never designed to manage.
Portnox delivers cloud-native IoT security solutions that help organizations discover, identify, and control connected devices using agentless Network Access Control (NAC), zero trust principles, and continuous posture evaluation. This approach improves visibility, enforces least-privilege access, and reduces risk across modern IoT environments without adding operational complexity.
Many IoT devices were not built with enterprise-grade security in mind. Organizations commonly face IoT security risks such as:
IoT devices are also frequently deployed outside of formal IT processes, creating Shadow IoT that operates beyond traditional security controls. These gaps make it difficult to detect unauthorized devices, enforce consistent access policies, or prevent lateral movement once a device is compromised.
Without effective IoT security controls, a single vulnerable device can provide attackers with a foothold into sensitive systems and data.
Portnox’s fully cloud-native IoT Device Trust suite helps you stay secure no matter how many things connect to your network. No more wondering if that random MAC address is the 3rd floor printer or a rogue laptop trying to breach the firewall – we can tell you the device type, name, manufacturer, OS, and more. Take your security to the next level by creating segmentation and access control policies so your camera isn’t an entry point for your customer database. And even better, we’ll tell you if that smart TV suddenly starts passing traffic like a laptop so you can quarantine it or remove it from the network entirely.

Staying ahead in IT means strengthening cybersecurity—and zero trust architectures now lead the charge. But let’s face it: embracing zero trust can feel daunting. With so many tools and complexities, it’s easy to lose your way.
To understand how organizations navigate zero trust, Portnox teamed up with TechTarget. We surveyed hundreds of IT and cybersecurity professionals across North America. Discover the insights we uncovered in our Trends in Zero Trust report.
IoT security solutions protect connected devices and the networks they operate on by providing visibility, access control, and continuous monitoring. These capabilities help organizations reduce risk, prevent unauthorized access, and manage large volumes of unmanaged devices more securely.
IoT security is important because many connected devices lack strong built-in protections. When unmanaged, they can be exploited to access sensitive systems, move laterally across networks, or disrupt critical operations.
Common IoT security risks include unknown or unmanaged devices, weak or shared credentials, outdated firmware, limited monitoring, and lack of segmentation. These gaps increase exposure to unauthorized access and security incidents.
Network Access Control improves IoT security by verifying devices before granting access and enforcing segmentation and least-privilege policies. NAC limits what devices can access if compromised and enables continuous enforcement across the network.
Zero trust applies to IoT environments by requiring continuous verification of devices rather than assuming trust. Devices are granted only the minimum access required, reducing exposure and limiting the impact of compromise.
Portnox secures agentless IoT devices using network-based identification, fingerprinting, and NAC policy enforcement. This approach allows organizations to control access and monitor behavior without installing software on the device.
Yes. IoT security solutions that provide visibility, access control, and audit logging help organizations demonstrate alignment with regulatory and industry frameworks while improving overall security posture.
