Armis
Armis helps enterprises discover and protect all connected devices without agents.
Armis provides an agentless cybersecurity platform that identifies, monitors, and protects managed, unmanaged, and IoT devices across enterprise networks in real-time. Unlike traditional solutions requiring agent installation, Armis uses passive network monitoring and an AI-powered Asset Intelligence Engine to detect threats across the entire attack surface regardless of device type or operating system. The platform serves Fortune 100/500 companies and government entities, delivering comprehensive asset visibility and threat detection without the operational overhead of agent deployment.
Problem solved
Enterprises lack visibility into all devices on their networks, particularly unmanaged and IoT devices, leaving critical security gaps that traditional agent-based solutions cannot address due to OS compatibility and deployment constraints.
Target customer
Fortune 100/500 companies, national governments, and state/local entities with complex IT, OT, and IoT environments requiring comprehensive device visibility and threat detection.

Competitors
Tenable
Agent-based vulnerability management platform; requires deployment across endpoints, less specialized in IoT and unmanaged device discovery.
Qualys
Cloud-based vulnerability and compliance platform; requires agents/connectors, broader compliance focus rather than device-centric threat detection.
Darktrace
AI-driven network detection and response; agent-optional but emphasizes behavior analytics; less specialized in asset inventory than Armis.
Why this matters: Armis has achieved unicorn status ($6.1B valuation) with $300M+ ARR in under a decade by solving a critical enterprise security problem—comprehensive device visibility without agent deployment overhead. The company's aggressive acquisition strategy (CTCI, Silk Security, OTORIO) and backing from top-tier investors (Goldman Sachs, Google, General Catalyst) position it as a consolidator in the converging OT/IT/IoT security space.
Best for: Large enterprises and government agencies managing complex hybrid IT/OT/IoT environments that need comprehensive device discovery and threat detection without the overhead of agent deployment.
Use cases
Hospital Network Asset Discovery
A UK health board deployed Armis to gain visibility into their medical device network and discovered 65,000-70,000 IP-connected assets, including medical devices they were previously unaware of. This enabled proper security scoping and risk prioritization across clinical and operational systems.
Airport OT/IT/IIoT Convergence
An international airport with complex operational technology, IT systems, and industrial IoT assets used Armis Centrix to achieve comprehensive visibility across their entire environment. The agentless approach eliminated deployment challenges across legacy OT systems and modern IT infrastructure, enabling unified cybersecurity and operations team coordination.
Fortune 500 Supply Chain Security
Large multinational enterprises use Armis to continuously monitor thousands of connected devices across global facilities and supply chains without installing agents. Real-time threat detection and asset intelligence enable rapid response to emerging threats without operational disruption.
Alternatives
Nessus/Tenable
Agent-based vulnerability scanner; better for traditional endpoint-centric environments but requires more deployment effort and excludes many unmanaged/IoT devices.
Cisco Catalyst Center
Network-centric management platform; tight integration with Cisco infrastructure but less specialized in threat detection and cyber intelligence compared to Armis.
Rapid7 InsightVM
Vulnerability management platform; broader compliance and scanning focus; agent-optional but less optimized for passive network monitoring and IoT device discovery.
FAQ
What does Armis do? +
Armis is an agentless cybersecurity platform that discovers, monitors, and protects all connected devices on enterprise networks—including managed, unmanaged, and IoT devices—in real-time. It uses passive network monitoring and AI-powered threat intelligence to detect risks and threats without requiring agents to be installed on individual devices.
How much does Armis cost? +
Armis uses a custom pricing model based on the size of your environment and the number of protected assets. Pricing is not publicly available; you must contact Armis for a personalized demo and quote.
What makes Armis different from competitors? +
Armis's agentless approach eliminates deployment constraints, enables visibility across all device types and operating systems, and doesn't require OS-specific compatibility. Its AI-powered Asset Intelligence Engine monitors billions of assets globally to identify cyber risk patterns, delivering unique threat intelligence without the operational overhead of agent management.
Who uses Armis? +
Fortune 100/500 companies, national governments, and state/local entities manage complex IT/OT/IoT environments. Notable customers include Colgate-Palmolive, United Airlines, Takeda Pharmaceuticals, Mondelēz International, and major international airports and health systems.
How does Armis compare to Tenable or Qualys? +
Tenable and Qualys are primarily agent-based vulnerability scanners requiring endpoint deployment, limiting visibility into unmanaged and IoT devices. Armis uses passive network monitoring to discover all devices regardless of type, provides real-time threat detection rather than periodic scanning, and specializes in comprehensive asset inventory and IoT security.
