Axonius has acquired Cynerio, a company specializing in medical device security, for more than $100 million in a cash and stock transaction.

The acquisition looks to address a challenge for healthcare providers, where the proliferation of connected medical devices has created a vast and unprotected attack surface. These specialized assets, essential to patient care, have historically been invisible to traditional security tools, creating significant risk to both patient safety and hospital operations.

“Hospitals have been operating with a massive digital security blind spot,” said Dean Sysman, co-founder and CEO, Axonius. “The very devices essential for patient care, from infusion pumps to MRI machines, have been completely invisible to cybersecurity teams, creating a dangerous, unprotected attack surface. This acquisition will help end that.”

By combining Axonius’ asset intelligence platform with Cynerio’s medical device expertise, the company is positioned to meet the immediate needs of hospitals while setting the foundation for broader Cyber-Physical Systems (CPS) security.

As part of the acquisition, Cynerio co-founder and CEO Leon Lerman will join Axonius as senior vice president. Co-founder Daniel Brodie will join the Office of the CTO. The Cynerio team joins Axonius to accelerate the company’s expansion into the healthcare market. Additional terms of the transaction were not disclosed.
