Healthcare is the most attacked vertical in 2025. The data is valuable, and the systems are life-critical. The answer is Zero Trust (ZT), but in a hospital, "Never Trust, Always Verify" can mean "Doctors can't access patient records in an emergency" if implemented poorly.
The Identity Challenge
Nurses share workstations. Doctors roam between wards. Hard MFA tokens are often impractical. We implement ZT in healthcare by focusing on contextual access. Is the user on a managed hospital tablet? Are they in the correct geo-location? If yes, seamless access. If they are logging in from a personal device at home? Step-up MFA.
Micro-segmentation for IoMT
Internet of Medical Things (IoMT) devices—MRI machines, infusion pumps—are notoriously insecure and unpatchable. They cannot have Zero Trust agents installed on them.
The solution is network micro-segmentation. We place these devices in isolated VLANs where they can only talk to the specific DICOM servers they need, and nothing else. If an infusion pump is compromised, it cannot reach the rest of the network.
