Axonius Acquires Medical Device Security Firm Cynerio in $100 Million Deal

Axonius has acquired Cynerio for $100 million in cash and stock to accelerate its expansion into the healthcare market.

Attack surface management solutions provider Axonius has announced the acquisition of medical device security company Cynerio for more than $100 million in cash and stock.

Prior to Axonius confirming the acquisition, it had been reported that the deal was worth $180 million, with the possibility of growing to $250 million.

Axonius provides a cybersecurity asset management platform that enables organizations to keep track of assets and ensure that they are compliant and protected. The platform covers SaaS applications, operating systems and other software, identities, and potential exposures.

Cynerio specializes in securing medical devices in healthcare environments and its solutions enable organizations to implement microsegmentation, protect sensitive information, and block ransomware attacks. 

Axonius said the acquisition will enable it to accelerate its expansion into the healthcare market.

“Hospitals have been operating with a massive digital security blind spot,” said Dean Sysman, co-founder and CEO of 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 integrating Cynerio’s deep clinical expertise with Axonius asset intelligence, we can offer healthcare providers what they’ve been asking for: a single source of truth capable of securing their entire clinical environment,” Sysman added.

Axonius has raised roughly $600 million since 2017, including $200 million in a late-stage funding round last year, and it has been valued at $2.6 billion. 

This appears to be the first acquisition announced by Axonius.
