What is Microsegmentation?
Identity-based microsegmentation enables organizations to rapidly secure their networks by applying granular, context-aware least-privilege access policies that automatically protect users, workloads, and devices wherever they appear on the network — preventing lateral movement attacks while eliminating the need for new hardware, agents, or complex network reconfigurations.
Why Modern Microsegmentation is Critical Today
- Lateral movement is used in 70% of healthcare breaches, making microsegmentation essential to prevent ransomware from spreading across clinical networks.
- The proposed 2025 HIPAA Security Rule mandates network segmentation, transforming it from an "addressable" specification to a mandatory requirement for healthcare organizations.
- Medical devices and IoMT systems create massive security gaps that can't be protected with traditional agents, requiring identity-based controls.
- Healthcare breaches average $5.2 million, but organizations with microsegmentation reduce incident response time by 40-60% and breach costs by 45%.
- Zero Trust requires granular network controls, and microsegmentation delivers the essential "Networks" pillar by enforcing least-privilege access everywhere.
The Business Value of Network Segmentation
- Reduce cyber insurance premiums by 15-30% through documented breach containment capabilities and enhanced security controls for sensitive patient data.
- Cut incident response times by 40-60% enabling faster isolation of compromised medical devices and preventing disruption to critical patient care systems.
- Achieve positive ROI within 12-18 months by eliminating complex VLANs, reducing operational overhead, and automating policy management across clinical networks.
- Streamline HIPAA and HHS 405(d) compliance with built-in reporting, automated policy enforcement, and comprehensive audit trails for all medical network activity.
- Protect patient safety and care continuity by preventing ransomware spread to life-critical systems while maintaining 99% uptime during security incidents
