TL;DR: Connected medical devices expand patient care but also widen attack surfaces, and Fortune Business Insights projects the global IoMT market will reach almost $188 billion by 2028 while 70.6 million Americans are expected to use remote patient monitoring by 2025, according to DigiCert’s source article. Digital trust is now a device identity and lifecycle problem, not just a network security problem.
Editorial analysis by NHI Mgmt Group, based on content published by DigiCert: “Digital Trust for connected medical devices”.
Key questions
Q: How should healthcare teams govern connected medical device identity?
A: Treat connected medical devices as managed identities with their own lifecycle.
Q: Why do connected medical devices require stronger risk assessment than ordinary IT systems?
A: Because a weakness in a connected medical device can affect care delivery, not just data confidentiality.
Q: What breaks when medical device certificates are not centrally governed?
A: When certificate governance is fragmented, devices can outlive their trust state, renewal windows are missed, and revocation becomes unreliable.
Practitioner guidance
- Establish certificate-backed device identity Require every connected medical device class to present cryptographic identity before it can join clinical systems, exchange telemetry, or accept remote management commands.
- Map device lifecycle ownership end to end Assign clear ownership for enrollment, renewal, revocation, replacement, and retirement so trust does not drift between manufacturing, hospital deployment, and patient use.
- Harden data-in-motion protections Use encrypted and integrity-protected channels for device telemetry, dosage commands, alerts, and integrations with electronic health record systems.
Bottom line: Connected medical devices widen the security problem because their trust relationships extend across manufacturing, deployment, clinical use, and updates.

IoMT security is a device identity problem before it is a network security problem. The article shows that connected medical devices must be trusted as individual actors, not simply treated as endpoints behind a hospital firewall. That shifts the control question to whether the device can be authenticated, monitored, and safely updated across its full life. For practitioners, the governance unit is the device identity and not just the subnet.
A question worth separating out:
Q: How do encrypted communications change IoMT security outcomes?
A: Encrypted communications protect both the confidentiality and the integrity of device traffic, which matters when the data is clinical telemetry, remote monitoring output, or commands that influence treatment. Without encryption and integrity checks, attackers can read, alter, or redirect sensitive device communications. For IoMT, secure transport is part of device trust, not a separate control layer.
