What we do

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

Discover & assess

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

Credentials

xIoT password management

Eliminate default credentials.
Enforce password standards across all devices.
  • Automatically removes default and weak xIoT passwords, closing a common attack entry point.
  • Enforces secure, automated password rotation at scale without disrupting operations.
  • Reduces attack surface and improves compliance with centralized visibility and governance.

Firmware

xIoT firmware management

Eliminate exploitable weaknesses.
Keep firmware current, safely.
  • Automatically discovers firmware risks across all xIoT devices, with CVE, KEV, and EPSS context.
  • Safely automates firmware upgrades and rollbacks at scale without operational disruption.
  • Automates firmware updates with policy-driven, scheduled upgrades and downgrades at scale.

Certificates

xIoT certificate management

Eliminate certificate weaknesses.
Enforce trusted identity across every device.
  • Automatically discovers certificate risks across xIoT devices, including expired, self-signed, or misconfigured certs.
  • Automates certificate deployment and renewal at scale, enforcing consistent, trusted identities.
  • Strengthens authentication while reducing attack surface and overhead through centralized certificate governance.
  • Extends Microsoft Active Directory and CyberArk Machine Identity (Venafi) certificate authority to xIoT devices.

Configurations

xIoT configuration management

Eliminate device configuration drift.
Enforce a secure, consistent posture across every device.
  • Remotely disables unnecessary and insecure network services, such as Telnet and FTP, to reduce device attack surface and enforce secure configurations.
  • Remotely configures and executes custom, device-specific actions at scale to securely manage diverse xIoT environments without manual intervention.

Platform Overview

0

Phosphorus eliminates manual work by:
• Automating remediation tasks
• Centralizing device management
• Reducing reliance on multiple tools
• Enabling security and operations teams to scale

👉 Result: Less manual effort, faster risk reduction, and improved security posture without increasing FTE count.

Risk Remediation

0

Phosphorus identifies and remediates:
• Default or reused passwords
• Vulnerable or outdated firmware
• Expired or misconfigured certificates
• Insecure configurations
• End-of-life devices
• Non-compliant or banned devices
• Known exploitable vulnerabilities (KEV-based prioritization)

Yes—this is a core differentiator.

Phosphorus enables:
• Bulk remediation across thousands of devices
• Scheduled changes within maintenance windows
• Policy-based automation

Examples:
• Rotate passwords across all devices
• Upgrade firmware fleet-wide

Yes. Phosphorus enables direct, automated remediation across xIoT devices, including:
• Password rotation and credential enforcement
• Firmware upgrades and downgrades
• Certificate replacement and renewal
•Configuration hardening, such as disabling Telnet or FTP

These actions can be executed at scale across thousands of devices with minimal operational impact.

Phosphorus automatically detects and replaces default or weak credentials across devices. It enforces password policies, schedules rotations, and securely stores credentials in an embedded vault, reducing one of the most common attack vectors in xIoT environments.

Phosphorus continuously identifies firmware versions across devices, enriches them with CVE, KEV, and EPSS intelligence, and automates patching workflows. It supports both upgrades and safe downgrades to maintain stability while eliminating exploitable vulnerabilities.
