NAC Solutions Overview

ORDR + Your NAC: Agile, Targeted Segmentation That Works NAC SOLUTIONS OVERVIEW

AI-powered enforcement through the access infrastructure you already own.

Why NAC Stops Short of Segmentation

NAC was built for managed endpoints — not today’s explosion of IoT, OT, and legacy systems. Without real-time device intelligence, enforcement breaks workflows, policies sprawl, and segmentation never gets off the ground.

Why most NAC projects stall:

• Limited visibility into non-user devices like IoT, OT, and legacy systems.

• Static, manual policies that can break workflows or leave gaps.

• Enforcement that’s too rigid, too broad, or too risky to turn on.

• Rollouts delayed by cross-team friction and fear of disruption.

Bottom line: NAC gives you a control point but not the intelligence to use it.

How ORDR Makes NAC Smarter

ORDR transforms your NAC into a real segmentation platform — one that works in complex, dynamic environments.

Why ORDR

Enriches NAC with full visibility of unmanaged and agentless devices.

Auto-generates least-privilege policies in NAC-native syntax.

Keeps NAC policies accurate as devices move or change.

With ORDR + NAC, you can:

See everything: ORDR discovers and classifies every device — from infusion pumps to badge readers — no agents needed.

Enforce safely: ORDR auto-generates segmentation rules in your NAC’s native syntax — then keeps them up to date as things change.

Understand behavior: We baseline how devices communicate, so you can build policies based on what’s normal — not guesswork.

Respond fast: Detect threats or anomalies in real time and trigger NAC-based isolation with a click.

See. Simulate. Segment — Through Your NAC.

ORDR makes NAC enforcement viable — not just configured, but working in production. No guesswork, no policy sprawl, no breaking critical systems.

See — Full NAC-ready context — MAC, VLAN, role, location, and risk.

Simulate — Preview how SGTs, DACLs, or VLANs will affect communication before you enforce.

Segment — Push NAC policies with a click and let ORDR keep them up to date.

Built for the NAC You Already Use

ORDR integrates natively with today’s leading NAC platforms — delivering dynamic, context-rich policies without needing to rip and replace.

Cisco ISE

• Assign SGTs and DACLs based on ORDR’s real-time classification and behavior modeling.

• Eliminate ACL sprawl with dynamic, least-privilege policies.

• Keep enforcement accurate as device roles and risks evolve.

HPE Aruba ClearPass

• Assign roles or VLANs dynamically based on ORDR’s risk and usage insights.

• Push access policies for unmanaged devices with Aruba-native syntax.

• Maintain segmentation as device states shift.

Fortinet FortiNAC

• Build enforcement groups from ORDR’s deep IoT, OT, and BMS profiling.

• Automate policy push for high-risk or segmented asset types.

• Quarantine suspicious devices using real-time risk triggers.

Forescout Platform

• Enrich Forescout visibility with ORDR’s business and risk context.

• Auto-populate policy groups based on device posture and usage.

• Adapt enforcement as the environment changes.

Extreme Networks ExtremeControl

• Discover and classify every device — even those without agents.

• Push segmentation rules across ExtremeControl infrastructure.

• Respond to risk and behavior signals in real time.

What You Can Do with ORDR + NAC

ORDR turns your NAC from a gatekeeper into a full enforcement engine. No rip-and-replace — just smarter, safer segmentation.

Zero Trust enforcement for unmanaged, high-risk, and unpatchable assets.

Threat containment using behavior-driven NAC quarantine.

Operational segmentation across cameras, HVAC, BMS, and clinical systems.

Safe rollouts with phased segmentation by device type.

Audit-ready compliance with HIPAA, NIST, PCI, IEC frameworks.

Smarter, Precise NAC Segmentation

NAC wasn’t built to understand every device — but ORDR was. By enriching your NAC with real-time intelligence, ORDR automates enforcement across every asset you care about, using the policies you already own.

Without ORDR

Full context into IoT, OT, BMS, and clinical systems; AI-powered behavior baselining and risk scoring; Auto-generated, simulation-ready segmentation; Native NAC syntax: DACLs, SGTs, VLANs, roles; Phased, low-risk segmentation by business priority

Frequently asked questions
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.
