In a world buzzing with connected devices—from hospital monitors to industrial robots—the need for smart, real-time cybersecurity has never been more critical. That’s where Armis comes into play. Acting like an ever-watchful digital guardian, This protects the very backbone of enterprises: their devices. Let’s dive deep into what makes Armis not just important, but essential.

What is Armis?

Before we explore how this reshapes enterprise security, it’s important to understand what it actually is.

Armis is an agentless cybersecurity platform purpose-built to monitor, identify, and protect unmanaged and IoT devices within enterprise ecosystems. Unlike traditional antivirus software, it doesn’t require software agents to be installed on devices. Instead, it passively collects data, analyzes behavior, and takes preventive action—all without disrupting operations.

Synonyms often include:

• Device Visibility Platform
• Agentless Threat Detection System
• Enterprise Security Monitor

This powerful tool is rapidly gaining popularity across sectors like healthcare, manufacturing, retail, and government, thanks to its intuitive design and AI-powered intelligence.

Breaking Down Armis

Let’s unpack what makes it so special by exploring its key features and how they work in tandem to secure enterprises.

At its core, it performs device discovery—detecting every connected device across your network in real time. Whether it’s a smart printer or a connected MRI machine, Armis sees it.

It then builds a contextual device profile using global intelligence, behavior patterns, and industry benchmarks. This way, it knows how each device should behave. When a device strays from the norm—say, a surveillance camera trying to access HR files—it flags it instantly.

Example: A retail store’s smart shelf system suddenly sends data to an unverified server. It halts the connection and alerts IT. That’s proactive protection in action.

History of Armis

Understanding the roots of it gives us a glimpse into how it evolved to become the security powerhouse it is today.

The founders of Armis, Yevgeny Dibrov and Nadir Izrael, recognized a growing blind spot in enterprise security: connected devices that couldn’t be secured through traditional means. Their vision was simple—build a security platform that could “see” everything without disrupting anything.

Types of Armis

Different industries face unique digital threats, and a one-size-fits-all approach simply doesn’t work anymore. Armis recognizes this and tailors its solutions for various sectors—from government agencies to hospitals. Let’s take a closer look at the core variations of platform and how each type is specifically optimized for its environment.

Armis Centrix™

Armis Centrix™ is the crown jewel of the platform—a next-gen cyber protection suite infused with AI from NVIDIA, built to monitor and defend critical infrastructure and operational technology (OT). Think power grids, water treatment plants, and transportation systems. It’s designed to identify vulnerabilities in real time, prevent operational shutdowns, and safeguard essential services from sophisticated attacks.

Example: A city’s traffic system powered by smart sensors and lights remains operational and secure, even when cyberthreats attempt to hijack signals or jam networks.

Healthcare Security

Hospitals and healthcare institutions are rapidly digitizing, with everything from heart monitors to infusion pumps now connected to the internet. Armis provides deep visibility into medical device behavior and ensures compliance with HIPAA and other regulations—without needing to install software on sensitive devices.

Example: If an IV pump behaves unusually—perhaps because it was infected via an unsecured vendor update—it isolates it instantly, preventing broader damage to life-saving systems.

Government Solutions

Cyberwarfare is very real, and public-sector agencies are prime targets. Armis helps secure government IT and OT environments, meeting strict national and international compliance standards. Whether it’s for military bases, election infrastructure, or public safety systems, they ensures zero-trust, policy-driven cybersecurity.

Example: A local municipality uses it to secure public Wi-Fi and surveillance infrastructure, ensuring safe communication across its departments.

Industrial IoT Security

Factories run on machines—and those machines are increasingly smart. Armis scans, analyzes, and secures all industrial devices, including programmable logic controllers (PLCs), robotic arms, and conveyor belts. It provides zero-downtime protection for complex operational environments.

Example: A car assembly line avoids a major production halt because it detected malware spreading through a vendor’s maintenance laptop before it reached the main systems.

How Does Armis Work?

Let’s walk through how it protects networks from the inside out—silently and powerfully.

Armis passively observes device behavior without needing an agent installed. It communicates with routers, switches, and Wi-Fi access points to map the entire network and every connected asset.

If it detects unusual behavior—like a connected thermostat sending out encrypted files—it sends alerts, quarantines the device if configured to do so, and integrates the data into your Security Information and Event Management (SIEM) platform.

This “eyes-everywhere” approach makes Armis indispensable for modern, sprawling enterprises.

Pros & Cons

No tool is perfect, but Armis comes pretty close. Let’s take a balanced look.

Pros	Cons
No need for agents or device downtime	Costly for small businesses
Real-time behavioral analytics	May need infrastructure fine-tuning
Rich integrations with existing systems	Requires initial training for teams
Supports a wide range of industries	Relies on consistent cloud access

Uses of Armis

Armis isn’t just another cybersecurity tool. It’s a versatile solution deployed across industries, each with its own unique risk profile. From securing life-saving devices in ICUs to monitoring municipal traffic systems, They proves its worth across real-world scenarios daily. Let’s explore how it works in action.

Healthcare

Connected devices are a double-edged sword in healthcare. While they enhance patient care, they also open doors to cyberattacks. This ensures hospitals can secure thousands of devices—like infusion pumps, imaging machines, and ventilators—without interrupting their function.

Real-World Scenario: A hospital experiences a ransomware attempt targeting digital thermometers. Armis detects the unusual behavior, blocks the connection to the attacker’s command server, and alerts staff—all in seconds.

Finance

Financial institutions depend on the security of ATMs, trading terminals, and banking software. It watches every transaction point for unusual activity, ensuring compliance and minimizing fraud risks.

Real-World Scenario: A bank’s ATM in a rural branch attempts to access an internal server that it normally doesn’t communicate with. Armis catches it, raises a red flag, and initiates isolation.

Retail

Retailers use smart POS terminals, digital price tags, and RFID systems—each of which can be a potential breach point. This helps businesses maintain uptime, prevent data leaks, and build consumer trust.

Real-World Scenario: A luxury brand store finds that one of its smart mirrors is sending data to a suspicious IP. Armis blocks the transmission instantly, preventing a potential leak of customer shopping preferences.

Smart Cities

As cities go digital with surveillance cameras, traffic sensors, and public Wi-Fi networks, it provides full-spectrum visibility over every connected asset. It ensures that public services remain operational, even under cyber duress.

Real-World Scenario: During a large festival, city officials use Armis to ensure drones, streetlights, and event Wi-Fi networks remain safe from hacking attempts that could endanger attendees.

Manufacturing

In manufacturing, even a minute of downtime can mean millions in lost revenue. It empowers manufacturers to identify threats before they disrupt operations and provides compliance with strict industrial safety regulations.

Real-World Scenario: A food processing facility detects a strange firmware update attempt on its refrigeration units. Armis intervenes before temperature control is compromised, protecting both safety and revenue.

Education

Schools are going digital faster than ever, with tablets, smartboards, and cloud-based testing systems becoming standard. This monitors school networks, blocks malware, and ensures safe access for students and staff alike.

Real-World Scenario: A student inadvertently downloads a malicious app. This isolates the student’s tablet and prevents the spread of malware across the school’s entire device network.
