Phosphorus Unified xIoT Security Management Platform
Automated xIoT platform discovering, remediating, and managing IoT, OT, IIoT, and IoMT vulnerabilities.
Vendor Information
Phosphorus Unified xIoT Security Management Platform Overview
Phosphorus Unified xIoT Security Management Platform is a Cyber-Physical Systems Protection Platform that delivers proactive discovery, automated remediation, and continuous management across the extended Internet of Things (xIoT) landscape including Internet of Things (IoT), Operational Technology (OT), Industrial IoT (IIoT), and Internet of Medical Things (IoMT) devices. Unlike legacy passive discovery solutions providing limited visibility or active scanners using brute-force polling that disrupts devices, Phosphorus employs patented Intelligent Active Discovery probing devices in native protocols with dynamically adjusted parameters achieving 100 percent device certainty while operating 98 percent faster than passive scanners and 95 percent more efficiently than legacy active tools. The platform addresses that xIoT devices comprise over 60 billion assets worldwide outnumbering traditional IT by five times, with default credentials, outdated firmware, expired certificates, and risky configurations creating attack vectors while organizations lack tools to remediate vulnerabilities at scale without operational disruption.
The platform operates through patented Genus-Species model supporting over 1,100 device manufacturers and more than one million unique device models using abstraction layer enabling native secure interfacing with devices communicating in their protocols. Core capabilities include Intelligent Active Discovery using customized tiered probe sequences, automated vulnerability remediation executing credential rotation 110 times more frequently and firmware updates 24 times more than manual approaches, and continuous monitoring detecting configuration drift. The platform delivers high-resolution device metadata including model, firmware version, serial number, certificate status, and end-of-life indicators enabling automated hardening, device isolation, and policy enforcement without agents or hardware.
Founded in 2017 by Chris Rouland and Earle Ady, Phosphorus raised over $65 million with $38 million Series A in 2022 and $27 million Series A2 in 2023 led by Evolution Equity Partners. The company assesses over 50 million IP addresses weekly, doubled devices under management in 2024, and serves Fortune 10 customers achieving 90 percent cost reduction. Recognized as Gartner Representative Vendor in CPS Protection Platforms and winner of 2025 IoT Breakthrough Award, maintains SOC 2 Type II certification.
Key Capabilities
Standardized capabilities mapped to this product's security niche
Dissects OT protocol payloads at the function code level, detecting unauthorized read/write operations, unusual register ranges, and firmware upload commands in Modbus, DNP3, EtherNet/IP, PROFINET, and OPC-UA traffic.
Maps actual traffic flows between IT and OT zones and between Purdue model levels, revealing unauthorized cross-zone connections and segmentation failures.
Baselines normal device communication patterns (command frequency, connection pairs, timing), and alerts on deviations, detecting reconnaissance, manipulation, and lateral movement.
Forwards enriched OT security alerts into enterprise SIEM and SOAR platforms with OT-specific context, enabling unified SOC operations without requiring OT-specialized analysts.
Discovers OT/ICS assets by analyzing existing network traffic (Modbus polls, Profinet broadcasts, EtherNet/IP connections), without sending any probe packets that could disrupt device operation.
Classifies discovered assets and traffic flows into Purdue Model levels (Level 0-4), supporting IEC 62443 zone and conduit documentation and compliance assessment.
