Legacy medical devices are not disappearing from healthcare networks. Many hospitals still depend on older equipment that remains clinically useful, expensive to replace and difficult to take offline. That reality creates a clear security challenge: connected medical devices need to be protected even when they were not designed for today’s cybersecurity demands.
Device Authority argues that healthcare organisations need an identity-first security strategy to manage this risk. It is not enough to know that a device is connected to a network. Healthcare providers need to know what the device is, whether it can be trusted, whether its credentials are valid and whether it should be allowed to communicate with other systems.
Many legacy medical devices were built before modern security standards became common. Some may lack strong authentication. Others may rely on outdated software, limited update options or weak certificate management. In a hospital setting, these weaknesses can be difficult to fix quickly because the devices may support critical services and cannot always be replaced or patched without affecting clinical operations.
An identity-first approach puts the device itself at the centre of the security model. Each device needs a trusted identity that can be issued, managed, renewed and revoked across its lifecycle. This makes it easier to control access, reduce exposure and support compliance without depending only on network-based defences. It also gives healthcare organisations a more practical way to manage risk across mixed estates of new and old devices.
For Device Authority, the message is commercially relevant. Healthcare is a sector where connected-device security is not optional, but replacement cycles are long and operational disruption carries real consequences.
