4 Reasons NAC Fails to Secure IoT, OT, and Unmanaged Devices - Tile
Network Access Control (NAC) solutions have fundamental limitations when protecting IoT, OT, and unmanaged devices due to protocol incompatibilities, lack of device intelligence, and enforcement gaps. This report identifies the four critical failures of traditional NAC approaches and explains why organizations need supplementary security strategies to protect these vulnerable device categories.
What you'll learn
- Understand why NAC enforcement fails on IoT and OT devices using non-standard protocols
- Identify visibility gaps that allow unmanaged devices to bypass traditional access controls
- Evaluate segmentation and discovery strategies to complement or replace NAC limitations

4 Reasons NAC Fails to Secure IoT, OT, and Unmanaged Devices - Tile
- Why does Network Access Control fail to protect IoT and OT devices?
- Traditional NAC solutions rely on standard protocols and device intelligence that IoT and OT devices often lack, creating protocol incompatibilities and enforcement gaps. ORDR's report identifies four critical NAC failures, including the inability to recognize and control non-standard devices that bypass conventional access controls entirely.
- What visibility gaps allow unmanaged devices to evade NAC?
- Unmanaged devices using proprietary or legacy protocols are invisible to NAC systems, allowing them to connect without proper identification or policy enforcement. ORDR's discovery and intelligence capabilities fill this gap by identifying all connected assets regardless of protocol, enabling true asset visibility across IoT, OT, and unmanaged device categories.
- What should replace or complement NAC for IoT/OT security?
- Organizations need supplementary segmentation and discovery strategies specifically designed for heterogeneous device environments. ORDR recommends implementing device-centric security that combines continuous asset discovery, behavioral intelligence, and micro-segmentation to protect vulnerable IoT and OT devices where traditional NAC cannot.
