About

Phosphorus Cybersecurity

Phosphorus Cybersecurity is a global IoT security company headquartered in Nashville's Gulch neighborhood, automating remediation of the biggest xIoT vulnerabilities.

Phosphorus Cybersecurity is a global IoT security company that opened its global headquarters in Nashville, Tennessee, consolidating offices previously in Georgia and California into a single Nashville base in the Gulch neighborhood on the edge of the city's Central Business District. The company provides full-scope security for IoT devices, addressing the reality that most enterprises today have far more embedded computing devices than people, creating a massive, often undetected cyber-attack surface. Phosphorus is securing the Internet of Things by fully automating the remediation of its two biggest vulnerabilities: out-of-date firmware and default credentials, targeting a threat category with a seven-year half-life for vulnerability patching and infrequent credential rotation. Founder and CEO Chris Rouland cited Nashville's business-friendly environment, quality of life and highly skilled workforce, along with the city's network of prominent universities like Vanderbilt, as key draws for relocating the company's headquarters. Phosphorus is described as the leading xTended Security of Things platform designed to find, fix and monitor the rapidly growing and often unmonitored Things of the enterprise xIoT landscape.
