Phosphorus Cybersecurity is a technology company.
Phosphorus Cybersecurity builds an xTended Security of Things (xIoT) platform designed to discover, secure, and remediate cyber-physical devices at scale. Their system provides full-lifecycle management for the security of operational technology (OT), Internet of Medical Things (IoMT), and traditional IoT devices. Key capabilities include comprehensive asset discovery, vulnerability assessment, password management, and firmware management, ensuring continuous monitoring and hardening of an organization's device footprint.
The company was co-founded by Chris Rouland, who serves as CEO, and Earle Ady, the CTO. Both bring a background of proven success in cybersecurity, having been involved in building multiple successful ventures prior to Phosphorus. They recognized a critical gap in securing the expanding landscape of interconnected physical devices beyond traditional IT networks, leading to the development of a specialized solution for this emerging threat surface.
Phosphorus serves a diverse range of sectors, including healthcare, banking and finance, data centers, retail, hospitality, and manufacturing, all of which increasingly rely on interconnected devices. The company’s vision is to enable enterprises to confidently deploy and manage their xIoT infrastructure, mitigating risks and ensuring operational resilience by providing robust security across their entire cyber-physical environment.

Phosphorus Cybersecurity is a Nashville, Tennessee-based company founded in 2017 that builds the leading xTended Security of Things (xIoT) platform to secure enterprise IoT and embedded devices.[1][3][4][5] It serves enterprises facing massive, unprotected cyber-attack surfaces from devices like security cameras, badge readers, and smart systems, solving critical vulnerabilities through automated remediation of outdated firmware, default credentials, patch management, asset inventory, compliance, and monitoring—addressing IoT's seven-year vulnerability patching half-life and infrequent credential rotation.[1][2][3][5] The platform integrates into existing security tools without added hardware or manpower, enabling full visibility ("Find Every Thing"), fixes ("Fix Every Thing"), and compliance ("Compliant in Every Thing").[2][5] With 60 employees, $12.6 million in revenue, recognition on Evolution Equity's 2025 Top 50 Cybersecurity Companies list, and plans for a new Nashville headquarters creating up to 50 jobs (primarily software engineers), Phosphorus shows strong growth momentum through capital raises and executive hires like Chief Strategy Officer Sonu Shankar in 2023.[1][3]
Phosphorus Cybersecurity was founded in 2017 by Chris Rouland (CEO), leveraging his proven track record in cybersecurity software innovation to tackle the exploding xIoT threat landscape where enterprises now have more embedded devices than people.[1][3][4][5] The idea emerged from recognizing IoT as the "softest target" on networks—unmonitored, unpatched, and credential-weak—prompting a U.S.-based team to develop the first fully automated remediation platform.[1][5] Early traction included proprietary IoT security software advancements, leading to headquarters consolidation from Georgia and California into Nashville's Gulch neighborhood, a $20 million capital raise in the announcement year to fuel sales growth, and expansion into global markets like the UAE and Saudi Arabia via partners.[2][3]
Phosphorus stands out in IoT security through patented, agentless automation that goes beyond discovery to true remediation, distinguishing it from triage-only tools:
Phosphorus rides the xIoT explosion trend, where connected devices now exceed global population and dominate enterprise endpoints, amplifying cyber risks amid rising attacks on unmonitored IoT (e.g., supply chain breaches).[1][5] Timing is ideal as regulations demand IoT compliance and enterprises shift from visibility-only tools to actionable fixes, with market forces like prolonged patching cycles (7-year half-life) and default creds creating a $12.6M revenue opportunity.[1][3] It influences the ecosystem by setting the standard for "basic blocking and tackling" in xIoT—pushing peers toward remediation platforms and partnering with integrators to normalize securing the "other half" of networks.[2][5]
Phosphorus is poised to dominate xIoT security as enterprises prioritize device hygiene amid escalating threats, with its Nashville HQ expansion, engineering hires, and 2025 accolades signaling accelerated R&D and market share gains.[1][3] Trends like AI-driven attacks and stricter compliance (e.g., CISA mandates) will amplify demand for its no-effort remediation, potentially scaling revenue beyond $12.6M through global partnerships and roadmap innovations under new CSO leadership.[1][2] Its influence could evolve from niche innovator to ecosystem staple, redefining enterprise security by closing the xIoT gap that leaves half of networks exposed—proving Rouland's vision that "device protection should be the first priority."[5]
