Moving Beyond Visibility — Why Enterprises Are Leaving Armis

Visibility is only the first step. Control is what stops attacks. 

Armis provides a view of devices on the network, but in today’s dynamic, hybrid environments, visibility alone isn’t enough. Devices are mobile, constantly changing IP addresses, using multiple protocols, and moving between network segments. Without understanding how these devices communicate in real time, security teams lack the context needed to enforce Zero Trust and prevent lateral movement. 

Where visibility falls short 

Armis gives organizations visibility — but it cannot deliver true, enforceable segmentation. Common challenges include: 

• Duplicate records inflate inventories because the same device appears multiple times, confusing IT and security teams. 

• Misclassified devices leave systems exposed when devices are labeled incorrectly or when MAC-to-IP relationships are misunderstood. 

• Rigid segmentation templates prevent dynamic adaptation, leaving policies unable to respond to real network dependencies. 

• Reactive quarantines only act after incidents occur, allowing attackers to move laterally before enforcement kicks in. 

• No true, adaptive segmentation across IT, IoT, and BMS, meaning devices can be visible but still uncontained. 

These gaps have real consequences. Inaccurate inventories undermine Zero Trust, create compliance headaches, and force teams to spend hours reconciling records, manually enforcing policies, or troubleshooting automation failures — time that could be spent on proactive security initiatives. 

Why enterprises are making the switch 

Organizations across industries — from healthcare and finance to manufacturing and enterprise IT — are replacing Armis with ORDR because it delivers what visibility alone cannot. 

• Maintains a single, trusted inventory by accurately identifying, classifying, and deduplicating every device, creating a single source of truth. 

• Enforces adaptive segmentation automatically across IT, IoT, and OT, blocking lateral movement before attacks can occur. 

• Protects critical systems proactively with automated enforcement that reduces reliance on reactive quarantines. 

• Feeds actionable data into IT/security systems like ServiceNow, SIEM, ITSM, and NAC, enabling automated workflows and simplified compliance reporting. 

• Learns and adapts continuously — unlike static templates, ORDR uses machine learning to refine segmentation and policy over time. 

• Eliminates misclassifications caused by protocol or flow mismatches, ensuring security decisions are based on accurate, correlated network intelligence. 

The ORDR Advantage: From Visibility to Control 

ORDR transforms visibility into actionable, enforceable security. By correlating MAC-to-IP mappings, multi-protocol flows, and real-time device behavior, ORDR provides a living inventory that continuously informs segmentation and policy. 

For CISOs, this means: 

• Reliable, deduplicated data to drive Zero Trust initiatives. 

• Dynamic, context-aware segmentation that adjusts as networks evolve. 

• Proactive enforcement that stops attacks before they spread. 

• Continuous learning and optimization through AI and machine learning. 

Unlike Armis, which reacts after an event or relies on rigid templates, ORDR gives security teams the intelligence and automation needed to act decisively in complex environments. 

The path forward 

Transitioning away from Armis doesn’t need to take months. Many enterprises complete the switch to ORDR in under 15 days, immediately strengthening their security posture  through accurate, deduplicated inventory and adaptive segmentation. 

With ORDR’s 90-day free trial, security teams can validate segmentation policies, uncover blind spots, and see measurable improvements in risk management and operational efficiency — without cost or commitment.
