Cylera

Cylera builds an asset visibility and risk management platform purpose-built for healthcare Internet of Things (IoT), Internet of Medical Things (IoMT), and operational technology devices — the infusion pumps, imaging systems, building controls, and clinical equipment that traditional IT security tools generally can’t see or safely scan. Its patented digital-twin methodology passively models device behavior to flag vulnerabilities and anomalies without the active probing that risks disrupting sensitive clinical equipment, which has historically been the core tension in medical device security.

Founded in 2017 by Timur Ozekcin and Paul Bakoyiannis and headquartered in New York City, Cylera has raised roughly $19.5 million to date, including a $10 million Series A led by Concord Health Partners and Maverick Ventures. The company has built a customer base of large health systems and hospital networks, including St. Luke’s University Health Network, RWJBarnabas Health (across 70 sites and more than 100,000 IoT devices), Weill Cornell Medicine, and several UK NHS trusts including Royal Bolton and The Christie.

The American Hospital Association named Cylera a preferred cybersecurity provider for its member hospitals, and Quadrant Knowledge Solutions ranked the company a leader in its SPARK Matrix for Connected Medical Device Security. Cylera sits in a crowded healthcare-IoT security field alongside Claroty/Medigate and Armis, competing primarily on the clinical-workflow context its platform attaches to each device finding rather than raw device discovery, which is now table stakes across the category.
