Cyber-Physical Systems (CPS) Security
Phosphorus Autonomous xIoT Security and Management Platform
Automated xIoT platform discovering and remediating IoT, OT, IIoT, and IoMT vulnerabilities.
Phosphorus Autonomous xIoT Security and Management Platform Overview
What it does
Phosphorus is an autonomous extended Internet of Things (xIoT) security and management platform covering Internet of Things (IoT), Operational Technology (OT), Industrial IoT (IIoT), and Internet of Medical Things (IoMT) devices. Its patented Intelligent Active Discovery probes devices safely in their native protocols, unlike passive monitoring or brute-force scanning, and the platform goes beyond detection to remediate device risk directly: rotating credentials, updating firmware, renewing certificates, and hardening configurations at fleet scale.
How it works
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.
Credentials and traction
Phosphorus won the 2025 IoT Breakthrough Award for IoT Security Platform of the Year and a 2025 Cybersecurity Excellence Award in the IoT Security category, along with a 2025 Cybersecurity Excellence Award for Most Innovative Company. It was named a Representative Vendor in the 2023 Gartner Market Guide for CPS Protection Platforms.
Key Capabilities
mapped to solution categoriesAssesses overall device-ecosystem risk (device trustworthiness, exposure, and operational context) as a continuous posture, distinct from per-CVE vulnerability management.
Discovers and fingerprints purpose-built connected devices (printers, cameras, infusion pumps, smart meters, building systems), classifying make, model, OS, firmware, and function, including unmanaged devices that cannot run an endpoint agent.
Establishes and manages per-device identity and access over the device lifecycle, including certificate and credential provisioning and rotation.
Monitors device configurations and manages firmware updates and configuration hardening at fleet scale, closing weak or default settings on connected devices.
Identifies, prioritizes, and helps remediate device vulnerabilities, including outdated firmware and exposed network services, across the connected-device fleet.
Prioritizes CPS/OT findings by real-world exploitability and operational impact rather than raw vulnerability counts, reflecting that most OT assets cannot be patched on IT timelines.
Identifies and prioritizes vulnerabilities across discovered OT and ICS assets using device, firmware, and exposure context, recommending safe, operationally feasible remediation or compensating controls for environments where patching is constrained.
Forwards enriched OT security alerts into enterprise SIEM and SOAR platforms with OT-specific context, enabling unified SOC operations without requiring OT-specialized analysts.
