Phosphorus Cybersecurity, Inc. provides xIoT cyber-physical security software for organizations that need to discover, assess, harden, monitor, and remediate connected devices across IoT, OT, IoMT, and IIoT environments. Its flagship Phosphorus Unified x IoT Security Management Platform combines active, device-native discovery with automated control actions so teams can move beyond passive visibility and address operational risk on unmanaged or difficult-to-secure assets. The platform is designed for agentless, non-disruptive deployment and supports on-premises, cloud, and hybrid environments. Phosphorus Cybersecurity, Inc. positions its offering around full-lifecycle xIoT security, covering visibility, risk assessment, remediation, continuous monitoring, and policy enforcement for cyber-physical systems in regulated and mission-critical operations.
Offerings, Capabilities, and Integrations
Phosphorus Cybersecurity, Inc. centers its platform on direct communication with devices using native protocols rather than passive traffic observation alone. That approach supports high-fidelity asset inventory, vulnerability and exposure assessment, automated hardening and remediation, continuous drift detection, device log collection, and compliance-oriented reporting across heterogeneous xIoT estates.
The platform is built to fit into existing security and operations workflows. Phosphorus Cybersecurity, Inc. integrates with Microsoft Sentinel, ServiceNow, CyberArk, Axonius, and Check Point, and it extends certificate operations for connected devices through integrations with CyberArk Machine Identity and Microsoft Active Directory Certificate Services. These integrations help teams connect xIoT visibility and remediation with SIEM, ITSM, PAM, and broader cyber asset management processes.
Products and Services
- Phosphorus Unified x IoT Security Management Platform: Flagship xIoT cyber-physical security platform for discovering, assessing, hardening, monitoring, and remediating IoT, OT, IoMT, and IIoT devices at scale through agentless, automated controls.
- xIoT asset discovery: Actively discovers, classifies, and profiles connected devices with detailed metadata such as device type, manufacturer, model, firmware version, and active protocols using direct device-native communication.
- xIoT vulnerability assessment: Identifies and prioritizes device risk across the xIoT estate, including weak credentials, vulnerable or outdated firmware, insecure configurations, end-of-life assets, and certificate issues.
- Global device network: Provides broad device coverage across more than 1 million unique device models and over 1,200 IoT, OT, IoMT, and IIoT vendors to improve identification and profiling accuracy.
- Prohibited device detection and response: Finds and enables response actions for devices prohibited under U.S. NDAA Section 889, including Huawei, Dahua, Hikvision, ZTE, Hytera, and devices running their OEM firmware.
- Password management: Automates detection and replacement of default or weak credentials, enforces password policies, and supports scheduled credential rotation and centralized governance for xIoT devices.
- Firmware management: Enables policy-driven firmware upgrades, downgrades, and rollback actions to reduce exposure from outdated or vulnerable device software without relying on agents.
- Certificate management: Discovers certificate risk across connected devices and automates certificate generation, installation, renewal, and lifecycle operations at scale.
- Configuration management: Supports remote device hardening actions such as disabling unnecessary or risky services and applying configuration changes to improve device security posture.
- Device state monitoring: Continuously monitors xIoT environments for drift and operational changes, including password resets, firmware changes, expired certificates, offline devices, and other device-specific conditions.
- Device log retrieval: Centralizes collection of device logs, audit records, and system events for security analytics, anomaly detection, triage, investigations, and forensics.
Target Customers
Phosphorus Cybersecurity, Inc. is aimed at large enterprises and other complex organizations with sizable, distributed xIoT estates. Its strongest fit is environments with thousands to hundreds of thousands of connected devices, high operational sensitivity, and requirements for accurate inventory plus automated remediation rather than visibility alone.
The company serves security, IT, engineering, facilities, and operations teams in sectors such as data centers and colocation, manufacturing and industrial environments, healthcare, financial services, hospitality and retail, critical infrastructure and energy, and federal or public-sector organizations. These customers typically operate in regulated or mission-critical settings where uptime, compliance, and device-level control matter.
Cloud Integrations and Marketplace
- Microsoft Azure Commercial Marketplace: Phosphorus Cybersecurity, Inc. has a verified marketplace presence through its Phosphorus Connector for Microsoft Sentinel listing.
- Microsoft Sentinel: Phosphorus Cybersecurity, Inc. provides a connector that sends xIoT asset data and device context into Microsoft Sentinel for monitoring, analytics, and incident response.
