Armis: Agentless Security for IT, OT, IoT, and IoMT

Efvery modern organization — whether it's a hospital, factory, or office environment — nowadays runs on thousands of connected devices. Besides laptops and servers, medical scanners, sensors, industrial PLCs, and even smart lighting are also part of the IT network.

But how do you secure all those devices that can't be installed with a security agent?

Armis Centrix, an advanced agentless security solution, offers just that.
The entire digital environment—IT, OT, IoT, and IoMT—is mapped and actively secured with Armis.

What is Armis in a nutshell?

Armis is a security platform designed to discover, evaluate, and protect all devices — managed and unmanaged — in your network, without having to install software agents.

This agentless approach makes it suitable for devices that can't accommodate an endpoint agent—think OT equipment, IoT, IoMT (medical devices), and legacy systems.

Complete visibility without agents

Armis operates differently than traditional security platforms. Instead of deploying software agents to every device, Armis passively observes all network traffic — both wired and wireless.
This also uncovers devices that can't accommodate an EDR agent, such as industrial control units, medical equipment, or IoT sensors.

• Full network scan: Every device is automatically recognized, classified, and provided with context.
• Real-time monitoring: Armis detects anomalous behavior immediately—not afterward through log analysis.
• Risk profiles: Each device is assigned a risk score based on vulnerabilities, firmware versions, and communication patterns.

This agentless approach provides a complete overview of all network assets, including vulnerabilities that often remain hidden for years.

Protection across all domains: IT, OT, IoT, and IoMT

While traditional security focuses primarily on IT, Armis bridges the gap between IT and OT.
This is essential, as production lines, healthcare equipment, and IoT networks are becoming increasingly connected to the IT infrastructure. This convergence makes security more complex—and that's precisely where Armis excels.

With Armis, you get:

• Visibility into OT networks without disrupting production processes.
• Security of medical devices (IoMT) without impacting system operations.
• Insight into IoT communication patterns, so unauthorized connections are stopped immediately.
• Integration with existing IT security-tools, such as firewalls, NAC systems, and SIEM tools.

Armis Centrix thus unites all security layers in a single platform, without having to compromise between availability and security.

Active real-time protection

Many security solutions analyze events only after the fact.
Armis does things differently: the platform operates continuously and responds immediately to threats.

As soon as anomalous behavior is detected — for example, a sensor connecting to an unknown IP address — Armis can automatically isolate, block, or segment.

This is crucial for organizations with critical processes, such as hospitals or production facilities, where every second counts.

Tangible benefits:

• Real-time detection and response — no delays due to log analysis.
• Integration with network and endpoint security — automatic isolation via existing infrastructure.
• No disruption to production processes — the agentless approach ensures passive, secure observation.

As soon as anomalous behavior is detected — for example, a sensor connecting to an unknown IP address — Armis can automatically isolate, block, or segment.

Practical example: Hospital network in the Benelux

Suppose a hospital in a large, internationally renowned city operates hundreds of medical devices — from MRI scanners to patient monitors and smart pumps. Many of these devices run on closed firmware and do not allow an EDR agent.

With Armis, the network is passively monitored:

• Within hours, all devices are automatically recognized and classified.
• Armis detects that a single scanner is attempting to connect to an unknown server abroad.
• The system flags the behavior as anomalous and automatically blocks the connection without disabling the device.

The result: real-time protection, zero blind spots, and complete control over all connected devices.

Agentless security for IT, OT, IoT, and IoMT

Protect even devices on which no software can be installed.

Why Armis is the future of network security

In a world where networks are growing exponentially, traditional endpoint security is not enough.
Armis brings visibility, control, and intelligence together in a single platform.
For organizationsIn the Netherlands and Belgium, this means reduced risks, increased continuity, and a faster response to cyber threats.
