Microsegmentation As A Strategic Approach To Healthcare Security
James Winebrenner, CEO, Elisity. The healthcare industry faces an unprecedented cybersecurity challenge. With the digitization of patient records, proliferation of connected medical devices and increasing reliance on interconnected systems, healthcare organizations have become prime targets for sophisticated cyber threats. According to the 2023 FBI "Internet Crime Report," the healthcare sector experienced more ransomware attacks than any other critical infrastructure sector in 2023, with the HIPAA Journal reporting over 93 million healthcare records compromised in business associates' data breaches that year alone. Traditional perimeter-based security measures were designed for a different era—one where threats remained largely outside organizational boundaries. Today's reality is starkly different. Once attackers breach a network, they can move laterally across systems and devices with alarming ease, compromising critical systems and sensitive data across the organization. Rethinking Healthcare Security Architecture Today's threat landscape demands a fundamentally different approach to network security. As healthcare boards and security leaders assess their risk management strategies, microsegmentation has emerged as a capability for modern security architectures that goes beyond prevention to focus on containment and resilience. Microsegmentation divides networks into secure zones, enabling organizations to isolate users, workloads and devices from one another and secure them individually. By establishing granular security controls around specific applications, data assets, devices and services, microsegmentation can effectively limit an attacker's ability to move laterally through the network—even after they've gained initial access. The concept itself isn't new, but its implementation has evolved significantly. While traditional segmentation relied primarily on firewalls and VLANs to create broad network divisions, modern microsegmentation leverages identity-based policies that can follow workloads regardless of their location, enabling true zero-trust security. The Value Of Microsegmentation In Healthcare Organizations Healthcare organizations face unique security challenges that make microsegmentation particularly valuable. First, healthcare environments contain an extraordinary diversity of devices, from medical equipment like MRI machines and infusion pumps to IoT devices controlling building systems like HVAC. A 2023 joint research effort by Securin, Health Information Sharing and Analysis Center (Health-ISAC) and Finite State identified nearly 1,000 vulnerabilities across 966 tested medical devices, representing a dramatic increase in exploitable vulnerabilities within healthcare technology. This exposure includes hospital information systems, imaging devices and clinical devices. Microsegmentation helps protect these systems even when they can't be patched. Second, healthcare operations require near-perfect uptime. When a ransomware infection spreads, the impact extends beyond data—it affects patient care. By containing threats to isolated segments, microsegmentation helps maintain continuity of essential healthcare services even during active security incidents. Third, healthcare networks typically contain numerous legacy systems with outdated operating systems that can't be readily replaced or patched. Microsegmentation provides a protection layer for these vulnerable yet essential systems. Implementation Strategies For Healthcare Organizations Despite the benefits, implementing microsegmentation in complex healthcare environments presents challenges. A successful approach requires: • Identity-Centric Implementation: Modern microsegmentation should be based on workload identity rather than network location or simple IP addresses, enabling consistent security across hybrid environments. This approach decouples access policies from underlying network infrastructure, making them more adaptable to changing healthcare delivery models. • Gradual, Risk-Based Deployment: Begin with the most critical assets and focus on the greatest risks. This might include systems containing sensitive patient data, life-critical medical devices or applications essential for clinical operations. • Clearly Defined Roles And Responsibilities: Microsegmentation projects touch multiple domains—networking, security, application teams and clinical departments. Creating a RACI (responsible, accountable, consulted and informed) matrix that clearly defines who does what across these domains is essential for success. • Balancing Security With The Clinical Workflow: Security controls must be carefully designed to protect systems without impeding essential clinical workflows. This requires close collaboration between security teams and healthcare practitioners. Overcoming Implementation Hurdles Many healthcare organizations have found microsegmentation challenging to implement using traditional approaches. The complexity of healthcare networks, limited cybersecurity resources and concerns about disrupting clinical operations have been major barriers. However, advancements in technology have dramatically simplified microsegmentation implementation. Modern solutions can be deployed without requiring new hardware, complex network reconfigurations or disruptive changes to existing systems. A Strategic Imperative For Healthcare Leaders Many healthcare boards and executives view microsegmentation as a strategic imperative rather than merely a technical control. It enables a fundamental shift from a breach prevention mindset to one focused on risk management and operational resilience. As healthcare delivery becomes increasingly digital and interconnected, the question isn't whether your organization will face a cyber threat but how effectively you'll contain and respond to it. Microsegmentation provides a foundation for this resilience, enabling you to protect patient data, maintain compliance and limit the impact of security incidents while continuing essential healthcare services. The time to act is now. Healthcare leaders must move beyond traditional security approaches to embrace a more comprehensive risk management strategy that safeguards the future of healthcare delivery.

Main Line Health Secures CIO 100 Honors Through Deployment of the Elisity-Armis Integration
SAN FRANCISCO & SAN JOSE, Calif.--(BUSINESS WIRE)--Armis, the cyber exposure management & security company, and Elisity, a pioneer in identity-based microsegmentation, today announced the results driven by their strategic integration that delivers frictionless, centrally managed Zero Trust access across enterprise networks. With this, both companies would like to congratulate their joint customer Main Line Health, which recently earned the prestigious CIO 100 Award for 2025, following their CSO50 Award in 2024, for their innovative cybersecurity implementation leveraging both platforms. 'The synergy between Armis and Elisity has fortified defenses against targeted cyber threats, improving overall operational efficiency with added layers of security and visibility,' said Aaron Weismann, Chief Information Security Officer for Main Line Health, whose team earned both awards for their innovative cybersecurity work. 'Microsegmentation is a key strategy for accelerating our Zero Trust program.' Aaron Weismann will be sharing Main Line Health's innovative approaches to cybersecurity at the upcoming RSA Conference (RSAC 2025) in San Francisco. His session, "Dr. Darkness or: How We Learned to Stop Worrying and Love Downtimes" (Thursday, May 1, 8:30 AM - 9:20 AM PDT), will explore the organization's innovative approach to maintaining clinical operations during cyber disruptions. The session, which also features Main Line Health Program Manager Anthony Fiore, will highlight how solutions like the Armis and Elisity integration help healthcare organizations enhance cyber resilience.
