Automatically harden and remediate xIoT devices
Remediate xIoT device vulnerabilities across credentials, firmware, certificates, and risky configurations.
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.
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.
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.
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.

Risk Remediation
5 questions
What risks can Phosphorus detect and fix?
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)
Can Phosphorus automate remediation?
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
Can Phosphorus automatically remediate device risks?
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.
How does Phosphorus help eliminate default passwords?
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.
How does Phosphorus manage firmware vulnerabilities?
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.
