Phosphorus is the industry’s only proactive xIoT breach prevention solution, delivering Attack Surface Management across every industry vertical through Active Discovery & Assessment, Hardening & Remediation, and Detection & Response for the full range of IoT, OT, IoMT, and Network-connected devices. The company’s award-winning Enterprise xIoT Security Platform is currently deployed in Fortune 100, 500, and 1000 companies, as well as government networks.

As the industry’s only provider of full-scope, preventative device protection and management for the xTended Internet if Things, Phosphorus is fixing and securing xIoT by fully automating the remediation of the biggest vulnerabilities—inaccurate and low-fidelity xIoT asset inventory, out-of-date firmware and certificates, default credentials, and end-of-life devices. The solution enables the largest enterprises and organizations to go beyond detection and low-resolution visibility to comprehensively FIND, FIX, and MANAGE their full xIoT estates.

The Phosphorus platform represents a combination of solutions for enterprise IoT and OT/IIoT/ICS networks covering several aspects of xIoT security, such as automated and agentless patching, high-resolution visibility, credential management, device hardening, and real-time monitoring. Phosphorus is the backbone platform to secure the rapidly growing and often unmonitored enterprise IoT and OT landscape. Providing unrivaled visibility down to the device model, serial number, firmware version, certificate, and end-of-life status, Phosphorus gives you full, granular visibility into all embedded xIoT devices on your network. Phosphorus’s patented capabilities allow you to update all of your IoT devices to the latest firmware, rotate credentials, update certificates, and perform device hardening and configuration with the click of a button.

Founded in 2017 by Chris Rouland, Rebecca Rouland, and Earle Ady, previously of Bastille, Endgame, and other successful Internet companies, Phosphorus is a trusted partner of Fortune 500s, Global 2000, and government agencies. Phosphorus is a privately held company headquartered in Nashville, TN, with investors including SYN Ventures and MassMutual Ventures.

How we are different

Phosphorus quickly and safely provides clients with complete xIoT visibility. It differentiates itself from legacy device scanners by not using expensive span ports for “sniffing” network traffic or knocking over IoT/OT networks through traditional IT scanning methods. Instead, Phosphorus is the only xIoT remediation platform that is able to safely and actively communicate directly with xIoT devices in their native language. In addition to providing MAC and IP addresses, it also detects the devices down to their model, serial number, firmware version, certificate status, end-of-life status, and support status. Unlike conventional detection tools, Phosphorus is specifically designed with xIoT device remediation in mind – providing the industry’s only xIoT breach prevention solution.

Phosphorus goes beyond discovery and passive detection to proactive remediation including credential hardening, device hardening, and configuration management capabilities. The platform’s credential management function automatically rotates the credentials for accessing xIoT devices at a set period, enabling them to comply with security and IT best practices/standards. When Phosphorus detects devices that still use default credentials, it automatically enrolls them in the Privileged Access Management (PAM) tool and immediately rotates the required credentials. The platform provides clients with critical network hygiene and xIoT breach prevention, securing IoT, IIoT, OT, and Network devices against threats such as the Mirai Botnet, nation-state attacks like QUIETEXIT, and insider threats.

Phosphorus provides automated, agentless firmware patching. The platform provides full visibility and metadata into every firmware version and associated CVE, and enables you to update or downgrade firmware at scale, allowing security and IT teams to maintain and keep up-to-date a network’s xIoT devices with a single click. It also circumvents daunting manual updates for devices recognized as a major pain point in the IT industry. Furthermore, Phosphorus enables enterprises to upgrade and downgrade firmware at scale.
