Ransomware, advanced persistent threats, and insider threats affect the healthcare industry more than the rest. Ransomware attacks have graduated past local machine exploitation and are now sophisticated enough to spread payloads across the network undetected by leveraging unsecured network paths.

Users, devices, and applications at hospitals, clinics, and healthcare facilities in general, offer too much network access to medical devices and patient information. There is little-to-no East-West network security coupled with a lack of visibility of unmanaged devices and shadow IT applications within the same zone of IoMT and other clinical resources. Third-party vendors require access to specific resources, yet more often than not can access the whole network. There is limited control, often deployed away from the access layer, and it is spread across many solutions using legacy methodologies, which incurs high operation and capital costs to maintain.

• Firewalls provide only limited visibility

• VRFs provide only partial fixes

• ACLs and NACs are a time-consuming and inefficient control

Elisity elegantly addresses the network security concerns around lateral movement through a cloud-delivered software-first platform. Elisity Cognitive Trust delivers fast and simple identity-based microsegmentation and least privilege access of users, devices, and applications, with policies enforced at OSI L2, L3, and L4, leveraging existing switching infrastructure and identity sources.
