Axonius Inc., the global leader in cyber asset intelligence, has acquired medical device security pioneer Cynerio for more than $100 million in a cash and stock transaction. The $2.6 billion cybersecurity unicorn aims to address a critical vulnerability in healthcare environments where connected medical devices have created an extensive unprotected attack surface.
The acquisition responds to a pressing challenge facing healthcare providers as the proliferation of connected medical devices—from infusion pumps to MRI machines—has remained largely invisible to traditional security tools. These specialized assets, while essential to patient care, have historically operated outside the purview of conventional cybersecurity measures, creating significant risks 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."
The strategic move represents a fundamental shift in healthcare cybersecurity approaches. Rather than securing medical devices in isolation, the combined platform will provide unified visibility across entire clinical environments. This integration addresses growing customer demand for a single platform capable of managing and securing both traditional IT infrastructure and connected medical devices.
"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.
The acquisition's significance extends beyond technical capabilities to address the interconnected nature of modern healthcare systems. Clinical and enterprise systems no longer operate in separate domains, requiring comprehensive security approaches that span the entire connected ecosystem.
"In today's healthcare environments, risk doesn't respect the boundaries between clinical and enterprise systems. The combination of Cynerio's specialized medical device context with Axonius' foundational asset intelligence addresses this challenge directly," said Rasu Shrestha, MD, MBA, EVP and Chief Innovation and Commercialization Officer at Advocate Health, and Chairman of the Board at Cynerio. "It provides the holistic visibility required to manage the entire connected attack surface, enabling healthcare organizations to build more resilient security programs. This is a vital step forward in helping ensure technology can securely and effectively support the core mission of patient care."
As part of the transaction, Cynerio co-founder and CEO Leon Lerman will join Axonius as senior vice president, while co-founder Daniel Brodie will join the Office of the CTO. The entire Cynerio team will integrate into Axonius to accelerate the company's expansion into the healthcare market. The acquisition positions Axonius to meet immediate hospital security needs while establishing a foundation for broader Cyber-Physical Systems (CPS) security initiatives.
