Armis Security: Transforming Network Defense with Asset-Centric Visibility

In today’s connected world, networks are no longer defined by traditional perimeters alone. They consist of a vast array of devices—from laptops and servers to IP cameras, printers, industrial controllers, and medical equipment—that operate across IT, OT, and IoT domains. This expanded attack surface requires a different kind of security approach. Armis Security offers an asset-centric perspective that shifts the focus from merely chasing threats to understanding and defending the devices that actually inhabit the network. By delivering continuous visibility, context, and risk-based prioritization, Armis enables security teams to identify gaps, respond faster, and reduce the likelihood of disruptive incidents.

Armis Security is purpose-built to address the realities of modern environments. The platform emphasizes comprehensive asset discovery, continuous monitoring, and risk scoring for every device, whether it’s connected to the corporate network, operating in a remote site, or hidden within the OT floor. This asset-centric strategy helps organizations move beyond traditional signature-based defenses and embrace a holistic view of their security posture.

Why asset visibility matters in today’s landscape

Visibility is the foundation of effective security. Without a true inventory of all devices, it’s nearly impossible to detect unauthorized or vulnerable endpoints, understand how devices interact, or enforce consistent policies. Armis Security tackles this challenge by identifying devices passively, without agents, and providing rich context such as device type, firmware version, network behavior, and risk indicators. When security teams know what is on the network, they can:

Pinpoint high-risk devices that could serve as entry points for attackers.
Monitor changes in device behavior that might signal compromise.
Apply access controls and segmentation to limit lateral movement.
Demonstrate regulatory compliance through accurate asset inventories.

In sectors like healthcare, manufacturing, and critical infrastructure, unmanaged devices have led to costly downtime and safety concerns. Armis Security helps organizations transform their approach from reactive alerts to proactive risk management, aligning security with business operations.

Core capabilities of Armis Security

Agentless asset discovery and classification: Armis Security maps every device on the network without requiring software agents. This creates a comprehensive, up-to-date inventory that spans IT, OT, and IoT devices, including legacy equipment often overlooked by traditional tools.
Continuous monitoring and behavioral analytics: The platform analyzes network traffic patterns and device behavior in real time, enabling rapid detection of anomalies and policy violations. This continuous monitoring reduces dwell time for threats and helps maintain a strong security posture.
Contextual risk scoring: Each device is assigned a risk score based on factors such as device type, ownership, firmware status, and exposure to sensitive segments. This prioritization helps security teams focus on the most critical issues first.
Policy enforcement and segmentation support: Armis Security supports policy-driven access controls and segmentation strategies that limit lateral movement, even for devices that cannot be fully updated or patched.
OT/IT convergence and interoperability: The platform is designed to bridge IT and OT security gaps, offering visibility into industrial control systems, medical devices, and other operational technologies alongside traditional IT assets.
Integrations with SIEM, SOAR, and EDR ecosystems: Armis Security complements existing security stacks by providing actionable telemetry that feeds into incident response workflows and centralized analytics.

Industries and use cases that benefit from Armis Security

Organizations across diverse sectors can leverage Armis Security to reduce risk and improve operational resilience. Common use cases include:

Healthcare: Ink devices such as infusion pumps, patient monitors, and imaging equipment can be brought under policy control, reducing the risk of ransomware and ensuring patient safety.
Manufacturing and energy: OT environments contain legacy systems with unique safety and uptime requirements. Armis Security provides visibility into industrial networks and helps enforce segmentation strategies that protect critical assets.
Retail and hospitality: IoT devices and connected point-of-sale systems create opportunities for attackers. A centralized view of devices accelerates threat detection and compliance.
Smart buildings and campuses: From HVAC controllers to cameras, asset-centric visibility ensures that only authorized devices operate within defined boundaries and that changes are monitored.

Beyond industry-specific benefits, Armis Security supports zero trust principles by verifying devices and enforcing least-privilege access, even for devices that do not support traditional security agents. This approach is increasingly important as workforces become more distributed and networks extend beyond traditional office boundaries.

How Armis Security differentiates itself

Compared with traditional endpoint protection or standalone IoT security solutions, Armis Security emphasizes asset-centric defense with deep device context and cross-domain visibility. A few distinguishing strengths include:

Broad device coverage: The platform detects a wide array of devices, including unmanaged and legacy assets, without requiring agents or prior configuration.
Unified view across IT, OT, and IoT: By consolidating views of diverse domains, Armis enables coordinated policy enforcement and faster decision-making for security operations teams.
Risk-based prioritization: Instead of chasing every alert, teams focus on high-risk devices and behaviors that pose the greatest threat to operations.
Operationally aligned insights: The data provided by Armis is designed to be actionable for security teams, network engineers, and compliance officers alike.

This alignment with real-world workflows helps reduce friction when deploying new protections and supports ongoing improvements in an organization’s security posture.

Implementation considerations and best practices

Adopting an asset-centric security platform like Armis Security should be approached with a clear plan. Consider the following best practices to maximize value:

Define success metrics: Establish measurable goals such as reduction in unrecognized devices, faster MTTD (mean time to detect) and MTTR (mean time to respond), and improved compliance reporting.
Start with a comprehensive discovery phase: Leverage Armis’ agentless discovery to build an initial asset inventory and categorize devices by risk tier. This baseline is essential for effective segmentation.
Prioritize high-risk assets: Use the platform’s risk scoring to prioritize remediation and access control decisions, especially for devices in sensitive segments (e.g., medical equipment, industrial controllers).
Integrate with existing workflows: Connect Armis Security to your SIEM, SOAR, and EDR tools to ensure alert enrichment, automated playbooks, and streamlined incident response.
Establish segmentation policies: Design and test segmentation rules that isolate critical assets while preserving business continuity and operational efficiency.
Iterate and measure: Treat security as an ongoing program. Regularly review risk scores, adjust policies, and re-run asset discovery to account for new devices.

Choosing the right asset-centric security platform

As you evaluate Armis Security vs. other approaches, consider how the solution aligns with your environment’s complexity and risk profile. Key decision factors include:

Depth of asset visibility: Is the platform able to identify a broad spectrum of devices, including hidden or legacy equipment?
Cross-domain coverage: Does it provide a unified view across IT, OT, and IoT, enabling holistic risk management?
Risk-based prioritization: Are there meaningful, actionable risk scores that translate into concrete remediation steps?
Deployment and maintenance: How quickly can you deploy, and how well does the solution fit with your existing security stack?

Armis Security is designed to address these questions with practical, device-centric capabilities that map to real-world operational needs. For security teams aiming to reduce attack surfaces without slowing business processes, the asset-first approach can be a compelling path forward.

Getting started with Armis

If you’re exploring how Armis Security can strengthen your security program, a structured evaluation helps uncover value quickly. Consider the following steps:

Engage with a trial or proof-of-concept to validate device coverage and data quality in your environment.
