Phosphorus Cybersecurity is a company focused on securing extended Internet of Things (xIoT) devices within enterprise environments. The company addresses a segment of enterprise infrastructure that includes connected devices such as phones, badge readers, smart devices, security cameras, and other IoT endpoints — categories that often outnumber traditional endpoints like laptops and mobile devices in business settings. The company's core offering is described as an enterprise xIoT remediation platform. Its approach is structured around three primary functions: discovery (finding every connected device to provide complete visibility), remediation (fixing identified problems using patented technology rather than simply triaging them), and compliance (bringing xIoT devices into alignment with organizational policies and regulatory requirements). Phosphorus positions its platform as integrating into existing security orchestration tools without requiring additional hardware, allowing organizations to extend security coverage to xIoT devices without adding significant operational overhead or personnel. The company was founded by Chris Rouland, who serves as CEO, alongside other cybersecurity industry veterans. The leadership team includes a CTO, COO, CFO, CRO, Chief Architect, and VP of Engineering, among others, with regional representation in areas including Saudi Arabia and the Middle East. Phosphorus maintains a partner ecosystem to support integrations with third-party security tools. The company's platform targets enterprises seeking to close security and compliance gaps across their xIoT device populations.
