The Thousands of Devices on Your Hospital Network Nobody Can Patch

Every hospital runs a fleet of connected medical devices — infusion pumps, MRI and CT scanners, ultrasound, ventilators, anesthesia machines, patient monitors. They are essential to care, they are on your network, and they are some of the hardest things on it to secure.

The problem is structural. Many of these devices:

• run Windows 7 or older operating systems,
• cannot easily be patched,
• cannot have antivirus installed,
• and are maintained only by the manufacturer.

You usually cannot fix the device. So you protect the environment around it.

Why medical devices are different

A normal endpoint can be patched, hardened, and monitored with standard tools. A medical device often cannot — it is FDA-regulated, vendor-locked, and built on a lifecycle measured in a decade, not a refresh cycle. Touching it the wrong way can void support or affect certification. That combination — high value, long life, no patching — makes connected medical devices a standing risk that traditional security tools simply were not built for.

The approach that works

Securing what you cannot patch comes down to controlling visibility and reach:

• Asset discovery — you cannot protect what you cannot see, and most hospitals do not have a complete device inventory.
• Passive monitoring — watching device behavior for anomalies without disrupting the device itself.
• Network isolation and segmentation — keeping device networks separated from clinical and administrative networks so a compromised device is contained.
• Virtual patching — protecting at the network layer when the device cannot be patched directly.
• Vendor risk management — holding manufacturers accountable for the parts only they can fix.

How LANStatus helps

Asset discovery, network segmentation, and monitoring are core managed-IT work — and they are exactly what unpatchable devices require. We help you build the inventory of what is actually on your network, isolate device traffic from the rest of your environment, watch for the anomalies that signal trouble, and coordinate with device vendors on patching and lifecycle. We learned the realities of clinical hardware the hard way, being responsible for the devices clinicians touch at the bedside — and that perspective shapes how we secure them.

Do you have a complete inventory of every connected medical device on your network — and do you know which network each one is allowed to reach?
