Traditional approaches for maintaining secure healthcare networks have long been dependent on maintaining separation of healthcare applications from IT networks and remote access users.

However, as healthcare organizations modernize their infrastructure with new technologies such as IoMT (Internet of Medical Things) devices and cloud applications/services, traditional zoning strategies are no longer sufficient to keep healthcare environments safe.

Challenges include:

• Risk of lateral movement of threats that cross from IT and remote users into cyber-physical and extended healthcare infrastructure
• Difficulties related to detecting and mitigating the spread of interzone threats
• Multivendor operational complexity and inconsistency in segmentation controls across extended healthcare environments
