Complete xIoT visibility.
No guesswork. No disruption.
Actively discover, classify, and profile every xIoT device with high-resolution context — using direct, device-native communication.
State of xIoT
The asset inventory problem
Lack of high-resolution, actionable inventory undermines ownership, segmentation, compliance, and vulnerability management.
Real-world example
U.S. government agencies lack complete IoT inventories
A GAO review found several federal agencies could not complete required IoT asset inventories, indicating unknown devices on their networks.1
State of asset inventory hygiene:
Passive discovery lacks device context
OUI and traffic analysis don’t provide firmware, model precision, or device state.
Authorization ambiguity
Managed, unmanaged, rogue, transient, orphaned.
Segmentation failures
Unauthorized xIoT devices discovered in production VLANs.
Regulatory & country-of-origin blind spots
Hard to identify prohibited or restricted devices.
The Phosphorus solution
Discovery must move beyond passive visibility
01
Get complete visibility
Phosphorus actively discovers and accurately classifies all xIoT devices through direct communication using native protocols. Instead of relying on passive traffic observation or OUI guesswork, the platform engages devices directly to validate identity, model, manufacturer, firmware, and configuration details — delivering complete, high-resolution visibility across your entire environment.
02
Gain deep device insights
Phosphorus delivers high-resolution device metadata by directly interrogating xIoT devices and extracting authoritative details at the source — including device type, manufacturer, model, firmware version, configuration attributes, and active protocols. By communicating natively with each device instead of relying on inferred traffic, the platform provides precise identification and deep visibility without agents, hardware sensors, or network disruption.
03
Zero disruption
Phosphorus uses a non-disruptive, purpose-built approach to identify and fingerprint IoT, OT, IoMT, and IIoT devices without relying on fragile network monitoring or intrusive scanning. Designed for sensitive cyber-physical environments, it delivers deep visibility and accurate classification while ensuring production systems and critical infrastructure remain fully operational — with no downtime, latency, or operational risk.

Phosphorus can discover and classify devices in minutes, not months, and does not require agents, hardware, or network changes. Organizations gain immediate visibility and can begin remediation almost immediately after deployment.
No. Phosphorus is agentless and does not require SPAN ports, taps, or additional hardware. It can be deployed on-premises, in the cloud, or in hybrid environments with minimal setup.
Discovery
Phosphorus uses its patented Intelligent Active Discovery, which interacts with devices through their native protocols instead of relying on network traffic analysis. This approach is far superior and delivers accurate device identification and risk assessment without disrupting operations or overwhelming sensitive systems.
Phosphorus currently delivers 96% precision for customers on average.
It delivers high-fidelity, device-level accuracy because it:
• Communicates directly with devices
• Collects real attributes (not inferred data)
• Profiles devices using firmware, services, and protocols
This avoids the inaccuracies common in:
• MAC address lookups
• Passive traffic analysis
Compliance & Zero Trust
Yes. Phosphorus identifies devices from restricted manufacturers, including those disguised through OEMs, white-labeling, and even unlabeled devices, and enables organizations to isolate or remediate them. This supports compliance with regulations such as NDAA Section 889.
