How to Use AI to Profile Devices on Your Network

Most security teams have a solid understanding of the devices they officially manage, but lack full visibility into everything actually connected to their environment. Without comprehensive visibility into connected devices, security teams can miss unmanaged, unknown, or misclassified assets that expand the organization's attack surface. That blind spot is where attackers often gain a foothold, move laterally undetected, and maintain persistence before security teams realize a compromise has occurred.

Why Traditional Profiling Leaves Gaps

Traditional device profiling tools rely on active scanning and MAC address lookups. Certificate-based authentication is another common requirement, one that many IoT and OT devices don't support. This approach works for managed laptops and servers. It fails on everything else.

According to Palo Alto Networks' 2025 Device Security Threat Report, which analyzed 27 million connected devices across 1,803 enterprise networks, 32.5% of all devices in corporate networks operate outside IT control. IoT sensors and OT controllers rarely accept software installs. Medical devices often carry regulatory restrictions that prohibit any software modification. Traditional tools manage these devices by granting access based solely on MAC or IP addresses, treating unknown assets as trusted exceptions.

That exception list grows until it becomes the rule.

Limitation	Impact
Requires agents	IoT, OT, and medical devices often can’t support software installs
Uses active scanning	Can disrupt critical industrial and clinical environments
Identified by MAC/IP only	Lacks device context; identifiers are easily spoofed
Point-in-time snapshots	Inventory becomes outdated quickly
Manual data correlation	Teams waste time correlating tools instead of responding to threats

How AI Profiles Devices Without Agents or Disruption

AI-powered device profiling doesn't install software. It doesn't scan. It listens.

ORDR's AI Protect for Security uses passive network monitoring and deep packet inspection (DPI) to observe how every device communicates. The AI analyzes what protocols each device speaks, HL7 or DICOM for medical equipment, Modbus or BACnet for industrial systems. It tracks every port each device uses and maps the communication patterns that define its normal behavior.

ORDR's AI has learned from over 100 million real-world device profiles across healthcare and manufacturing environments. That training lets it accurately classify unknown and proprietary devices based on communication behavior alone, no signature required.

Within 24–48 hours of deployment, ORDR builds a complete, continuously updated inventory of every connected asset across on-premises and cloud environments, without touching a single device.

Step	What Happens	Outcome
1. Passive Listening	AI monitors network traffic without agents or active scans	No operational disruption
2. Protocol Analysis	Deep packet inspection identifies each device’s communication language	Accurate classification beyond IP/MAC
3. Behavioral Fingerprinting	AI maps each device’s real communication patterns	Behavioral baseline established
4. Device Classification	AI matches profiles against 100M+ learned device types	Make, model, firmware, and function identified
5. Continuous Updating	Profiles adapt as device behavior changes	Inventory stays accurate in real time

What AI Profiling Actually Reveals

Knowing a device exists on your network is step one. Understanding whether it poses a real risk is what matters.

More than 50% of IoT devices contain critical vulnerabilities that attackers can exploit without authentication. Traditional profiling tools identify a device's presence. AI profiling goes further, correlating each device's identity with live CVE data and actual network exposure. It also detects deviations from established behavioral baselines, flagging threats before they escalate.

One in three data breaches now involves an IoT device as the initial entry point. The response most organizations give after the fact: "We didn't know that device was there, or what it was doing." AI profiling closes that gap before an incident forces the question.

What You Know	Traditional Profiling	AI-Powered Profiling (ORDR)
Device exists on network	✓	✓
Make, model, and firmware version	Managed devices only	All connected devices
Normal communication behavior	✗	✓
Active vulnerabilities tied to device identity	✗	✓
Real-time behavioral anomalies	✗	✓
Risk prioritized by actual network exposure	✗	✓

From Profile to Protection

Device profiling only earns its place in a security stack when it drives action. Most visibility tools stop at the dashboard.

ORDR connects profiling directly to enforcement. Behavior-based device profiles feed AI-generated, least-privilege segmentation policies, rules that define exactly what each device should communicate with, and nothing else. A video camera connects only to its camera management system. A medical imaging device connects only to the PACS server it needs.

Before any policy goes live, ORDR simulates it against real traffic. Security teams see exactly what the policy will affect, validate operational safety, and then push enforcement, with no downtime, no guesswork.

Profiling isn't the finish line. It's the starting point for security that acts.

Stage	What ORDR Does	What You Get
Discovery	Passive monitoring identifies every connected device	Complete, verified inventory
Profiling	AI establishes behavioral baselines for each device	Context beyond identification
Risk Assessment	Device profiles correlate with CVEs and network exposure	Prioritized, actionable risk
Policy Generation	AI generates least-privilege policies from real traffic	Enforcement-ready controls
Validation	Policies simulate against live traffic before deployment	Safe enforcement, no surprises
Continuous Monitoring	Profiles update as device behavior changes	Protection stays current

See every device on your network, and act on what you find.
