Phosphorus autonomous xIoT security and management platform

Secure and manage connected devices at machine scale; safely, automatically, continuously, with human oversight, not limitations.

Deploys at scale in minutes. No SPAN ports, TAPs, packet brokers, or proprietary hardware required.

The platform that puts you in control

Most xIoT (IoT, OT, IoMT, and IIoT) security tools stop at identifying devices and vulnerabilities, leaving remediation to overburdened security and operations teams. The Phosphorus Platform automates discovery and risk assessment, device hardening and remediation, as well as continuous monitoring and management for every connected device.

Discover & assess

Safely discover, classify, and assess all xIoT devices in minutes, with no expensive hardware, SPANs, TAPs, or packet brokers.

Harden & remediate

Automatically remediate xIoT device vulnerabilities, including credentials, firmware, certificates, & risky configurations.

Monitor & manage

Continuously monitor and manage all xIoT devices, while detecting and responding to device drift.

Modular flexibility

Select the platform capabilities your security and operations teams need to reduce xIoT risk and strengthen operational resilience across your organization. Add capabilities as your organization matures.

Discover and assess

Visibility across tens of thousands of connected devices with high-fidelity data on device attributes, vulnerabilities, misconfigurations, and policy compliance gaps.

xIoT asset discovery

  • Discover and profile devices with extensive contextual detail across a wide range of device attributes.

Attributes include

  • Device type
  • Manufacturer
  • Model/series
  • IP address
  • Active protocols
  • Firmware version
  • Open ports
  • Device-specific information

xIoT vulnerability assessment

  • Identify, classify, and prioritize vulnerabilities across your xIoT estate to understand and mitigate risks before attackers can exploit them.

This includes

  • Default passwords in use
  • Firmware availability
  • CVEs with added context from CISA's Known Exploited Vulnerabilities (KEV) catalog and FIRST's Exploit Prediction Scoring System (EPSS)
  • End-of-life devices
  • Insecure configurations
  • Expired or self-signed certificates

Prohibited device detection and response

  • Discover and remotely disable devices banned by the U.S. Government (NDAA Section 889 – Chinese-manufactured).

This includes

  • Devices manufactured by Huawei, Dahua, Hikvision, ZTE, and Hytera
  • Devices with firmware that was OEMed from the above companies, regardless of device manufacture.

Harden & remediate

Don’t just find it. Fix it. Remediation tasks can be scheduled across thousands of devices within defined maintenance windows.

Password management

  • Automated default and weak password remediation
  • Scheduled credential rotation
  • Granular policy enforcement
  • Embedded password vault

Firmware management

  • Upgrade and downgrade firmware at scale
  • Automated firmware discovery & risk context (CVE, EPSS, KEV)
  • Safe upgrades and downgrades

Certificate management

  • Manage and renew certificates at scale across diverse device sets
  • Identify devices operating with expired, self-signed, or improperly configured certificates
  • Automatically update them at scale (renew and install)

Configuration management

  • Remotely disable unnecessary network services on a device, such as Telnet or FTP
  • Take custom device-specific actions
  • Configure devices remotely at scale

Monitor & manage

Centrally monitor and manage device configurations, security analytics, and ransomware resilience with backup and restoration.

Device state monitoring

  • Continuously monitor xIoT estates to detect and alert on device drift and operational changes.

This includes

  • Out-of-band password reset
  • Out-of-band firmware upgrade or downgrade
  • Out-of-band certificate change
  • Device offline
  • Device reset
  • Custom device-specific alerts

Device log retrieval

  • Centralize log collection and analytics for detailed device-level security analysis, anomaly detection, triage, and forensics.

Retrieve device logs from multiple device types and manufacturers, including

  • Audit logs
  • System events

Device backups

  • Increase resilience against ransomware with device configuration backup and restoration
