Phosphorus is an xIoT security and management platform that discovers, assesses, and actively remediates risk across connected devices, including IoT, OT, IoMT, and IIoT. It enables organizations to move beyond visibility by automating actions such as password rotation, firmware updates, certificate management, and configuration hardening at scale.

Phosphorus delivers full lifecycle xIoT security across three core pillars:
1. Discover & Assess
High-fidelity device inventory (15+ attributes per device)

Identification of:
• Default credentials
• Vulnerabilities (CVEs with KEV + EPSS context)
• End-of-life devices
• Misconfigurations
• Certificate risks
• Safe discovery using native protocols (no reckless scanning)

2. Harden & Remediate
• Automated password rotation at scale
• Firmware upgrades/downgrades
• Certificate lifecycle management
• Configuration hardening (disable services, enforce encryption)
• Compliance enforcement (e.g., NDAA banned devices)

3. Monitor & Manage
• Continuous device monitoring for drift
• Log collection and analysis
• Backup & restore for ransomware resilience (In Development)
• Device-level security analytics

👉 The key differentiator: Phosphorus doesn’t just find issues—it empowers you to fix them at scale.

Phosphorus is designed to integrate seamlessly into your existing security and IT ecosystem, extending the value of your current tools by adding high-fidelity xIoT visibility and automated remediation.

Rather than replacing existing investments, Phosphorus enriches, operationalizes, and automates them.

Phosphorus can discover and classify devices in minutes, not months, and does not require agents, hardware, or network changes. Organizations gain immediate visibility and can begin remediation almost immediately after deployment.

No. Phosphorus is agentless and does not require SPAN ports, taps, or additional hardware. It can be deployed on-premises, in the cloud, or in hybrid environments with minimal setup.

Organizations using Phosphorus typically achieve:
• Full visibility into all connected devices
• Reduction in attack surface through automated remediation
• Elimination of default credentials and insecure configurations
• Faster response to vulnerabilities and compliance requirements
• Lower operational burden on security teams

The Genus-Species Model

One of the early technical challenges was scale.
xIoT environments include:
• Millions of device models
• Thousands of manufacturers
• Constantly evolving firmware and configurations

However, Phosphorus discovered that devices operate on a Genus-Species model:
• Devices are identified at both the manufacturer family level (genus) and the specific model/variant level (species)
• This enables rapid, accurate classification across over a million device models
• New device types can be added quickly without rebuilding detection logic
• Example: for 10,000 printer models (species) under a major manufacturer, they only operated on five different types of software-on-a-chip (genus)

👉 This approach allows Phosphorus to scale device coverage exponentially, while maintaining high-fidelity accuracy required for remediation—not just visibility.

Phosphorus supports a wide range of connected devices, including:
• IoT devices like cameras, printers, and badge readers
• OT and industrial systems such as PLCs and controllers
• IoMT devices like infusion pumps and patient monitors
• Network infrastructure and building management systems

This breadth enables a complete view of the xIoT attack surface across industries.

Phosphorus uses its patented Intelligent Active Discovery, which interacts with devices through their native protocols instead of relying on network traffic analysis. This approach is far superior and delivers accurate device identification and risk assessment without disrupting operations or overwhelming sensitive systems.

Phosphorus currently delivers 96% precision for customers on average.

It delivers high-fidelity, device-level accuracy because it:
• Communicates directly with devices
• Collects real attributes (not inferred data)
• Profiles devices using firmware, services, and protocols

This avoids the inaccuracies common in:
• MAC address lookups
• Passive traffic analysis

Phosphorus provides deep risk visibility, including:
• Default or weak credentials
• Outdated or vulnerable firmware with CVE, KEV, and EPSS context
• Expired or self-signed certificates
• Insecure configurations and open ports
• End-of-life or unsupported devices

Banned or high-risk devices, including those restricted by NDAA Section 889

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.

Phosphorus reduces risk by combining three core capabilities in a single platform:
1. Discover and assess every device
2. Harden and remediate vulnerabilities automatically
3. Continuously monitor for drift and emerging risk

This approach ensures that risks are not only identified but actively eliminated.

Phosphorus extends Zero Trust principles to connected devices by ensuring every device is identified, authenticated, continuously assessed for risk, and actively managed. It aligns directly with CISA’s Zero Trust Maturity Model across identity, device, network, and data pillars.
