NAC Solutions Overview
Network Access Control (NAC) solutions protect enterprise networks by controlling which devices connect and what resources they access. This brief explains how AI-powered NAC enhances security for IoT, OT, and legacy systems through real-time device intelligence and automated least-privilege policies. Learn how NAC integrates with segmentation strategies to reduce attack surface across government, healthcare, manufacturing, and financial organizations.

NAC Solutions Overview
- How does NAC improve security for IoT and OT devices?
- NAC solutions use AI-driven device classification to identify and control what IoT and OT devices connect to your network in real-time. ORDR's approach automatically enforces least-privilege policies, ensuring legacy and emerging systems can only access the resources they need, significantly reducing unauthorized lateral movement and attack surface.
- What is the difference between NAC and network segmentation?
- NAC controls which devices can connect and what resources they access at the access point, while segmentation isolates different device groups within the network. ORDR integrates both strategies—NAC enforces access policies while segmentation isolates IoT/OT devices from critical enterprise networks, creating layered protection against breaches.
- Can NAC work with legacy systems and devices without agents?
- Yes, agentless NAC solutions are essential for legacy IoT and OT devices that cannot run software agents. ORDR's AI-powered approach classifies and controls these devices based on behavioral intelligence and network traffic analysis, enabling security without disrupting operational technology environments.
