Armis vs Asimily:
2026 Comparison

Introduction

Independent customer research points the same direction. In KLAS Research’s 2026 Healthcare IoT Security report, Asimily scored 96.6 out of 100 on customer experience, ahead of Claroty (92.1), Armis (91.1), and ORDR (89.4). KLAS respondents credited Asimily’s risk intelligence and vulnerability identification and described Armis as a cost-effective option for large-scale IoT visibility (TechTarget, January 2026; KLAS report). KLAS surveyed healthcare organizations only, but the capabilities respondents rated, such as risk intelligence and vulnerability identification. Published in January 2026, the KLAS report is an independent evaluation that rates Asimily and Armis on the same six customer-experience criteria. The sections below compare the two platforms feature by feature.

Armis vs Asimily at a Glance

The rows below summarize where the platforms match and where they differ. Each row repeats a row from the detailed tables that follow.

1. Inventory and Visibility

Armis and Asimily both offer inventory and visibility: both collect data passively, query IoT devices actively, inspect packet headers and payloads, and build detailed inventories of Internet of Things (IoT), operational technology (OT), and Internet of Medical Things (IoMT) assets. Active querying suits only devices that tolerate the traffic, so both platforms pair it with passive collection. Both also enrich device records through integrations; Asimily’s include Active Directory, Dynamic Host Configuration Protocol (DHCP) servers, network access control (NAC) systems, vulnerability scanners, and mobile device management (MDM) tools, and it acts through NACs and firewalls.

2. Exposure Management

Armis and Asimily both detect and prioritize vulnerabilities and classify them with MITRE ATT&CK; they differ in how far each goes in testing exploitability in the customer environment. Armis describes VIPR Pro, its prioritization and remediation module, as weighing asset context, business risk, threat intelligence, and likelihood of exploit, and as grouping findings that share a fix. Asimily’s ATT&CK Analysis uses MITRE classification and goes beyond it to determine whether a vulnerability is actually exploitable on a specific device in a specific environment, then turns the result into mitigation recommendations that also cover legacy devices. Asimily’s Risk Simulator models how a fix would change a device’s risk score before anyone acts, a step Armis Centrix does not include.

3. Threat and Response

Armis and Asimily both create anomaly policies that notify or quarantine and connect to NACs and firewalls for response actions; the clearest difference is packet capture. Asimily captures traffic from any monitored device, and a violated policy can start a capture automatically, so incident responders begin with the traffic itself rather than only an alert. Asimily alert rules can also be built on any parameter without code. Detection helps only when a team can act on an alert and reconstruct what happened.

4. Risk Mitigation

Armis and Asimily both group assets and offer segmentation guidance; they differ most in whether segmentation policy is created, simulated, and maintained inside the platform. Armis acts on findings through workflow: Armis says VIPR Pro assigns remediation owners with AI, syncs tasks with ticketing systems in both directions, and groups findings into remediation campaigns. Asimily’s Segmentation Orchestration creates policies automatically, targets them at the attack vectors found on each device, simulates them against live traffic with Policy Simulation, and previews the enforcement plan before commit. Continuous Segmentation then automatically applies NAC and firewall policies to new devices that match a policy’s criteria. Asimily also provides IoT Patching and password management for supported IoT device types, which Armis Centrix does not include.

5. Governance, Risk, and Compliance

Asimily Configuration Control captures device configuration snapshots and tracks changes against them; Armis Centrix does not include configuration snapshots. Snapshots of IoT, OT, and IoMT device configurations establish a known good state, which gives teams a reference point for audits and for recovery after an accidental or malicious change. Asimily also keeps a change history for each device. Armis describes VIPR Pro as tracking remediation task status and exception requests for executive reporting.

6. Sample Integrations

Armis and Asimily both integrate across IT and security tools. Armis offers a large integration catalog, and ServiceNow, which acquired Armis in April 2026, has said it will connect Armis asset intelligence to its workflows; Armis says VIPR Pro ingests findings from scanners and other security tools. Asimily correlates network, identity, vulnerability, endpoint, and service management data into one record per device, integrates with ServiceNow Service Graph, and can apply policies through supported NACs and firewalls. Asimily integration categories and sample products include:

• AI: any LLM Provider
• CMMS/CMDB: ServiceNow Service Graph, Ivanti, i-doit
• DHCP: Infoblox, BlueCat, EfficientIP
• Endpoint Configuration Management: Microsoft Configuration Manager
• Endpoint Detection and Response (EDR): CrowdStrike Falcon, Microsoft Defender, Sentinel One
• Identity & Access Management (IAM): Active Directory / LDAP, Azure SSO, SAML
• ITSM: ServiceNow ITSM, Jira, BMC Helix
• Location Services: Cisco Spaces, Aruba AirWave
• Mobile Device Management: Microsoft Intune, Jamf Pro, Jamf Cloud
• Network Access Control (NAC): Cisco ISE, Aruba ClearPass, Palo Alto Panorama
• Network Segmentation: Color Tokens
• Network Traffic Sources: NetFlow, sFlow, SNMP Walk
• SIEM: Elastic SIEM, CrowdStrike LogScale, Palo Alto Cortex XSOAR
• Threat Intelligence: Cisco XDR, CrowdStrike Falcon X
• Vulnerability Management (VM): Tenable, Qualys, Rapid7

(Not a complete list; integrations are added regularly.)

7. Deployment Considerations

Armis and Asimily both avoid re-IP work and both offer software as a service (SaaS) and on-premises deployment; Armis offers on-premises in limited cases. On-premises deployment matters for air-gapped and internet-restricted networks, which many OT environments use. Asimily collects data agentlessly through the Asimily Edge collector software, which runs on a dedicated appliance, on a virtual machine, or as an app on switches that support Cisco application hosting.

When Armis Fits Better

Armis is the closer fit for organizations standardized on ServiceNow: ServiceNow completed its acquisition of Armis on April 20, 2026 (Verdict), and has said it will look to connect Armis asset intelligence to its risk, remediation, and reporting workflows. Armis also suits teams that want one prioritization and remediation workflow across connected devices, cloud, code, and application security findings, which Armis says VIPR Pro is built to consolidate. US federal buyers who must have cloud deployments may weigh Armis’s Federal Risk and Authorization Management Program (FedRAMP) authorization. In KLAS Research’s 2026 healthcare IoT security interviews, Armis customers also cited its cost-effectiveness for large-scale IoT visibility (TechTarget).

The Bottom Line

While both platforms provide foundational passive discovery, packet inspection, and vulnerability identification, direct customer evaluations show clear distinctions in performance, scope, and operational outcome:

Asset Discovery & Profile Depth: Head-to-head proof-of-concept (POC) comparisons demonstrate that Asimily discovers a higher percentage of total devices and populates richer profile data per asset. Operating agentlessly across the entire cybersecurity stack, Asimily acts as a single source of truth for assets, applications, workloads, and middleware. By combining deep packet inspection, AI/ML classification trained on over 10 million device profiles, safe active querying, and 150+ ecosystem integrations (including Active Directory, CMDB, EDR, and MDM), Asimily identifies nearly 100% of connected IoT, OT, IoMT, IT, and AI assets with 98%+ accuracy.

Workflow vs. Active Remediation: Armis (now part of ServiceNow) focuses on consolidating connected device findings into unified IT prioritization and ticketing workflows. Asimily drives direct risk reduction by tying findings to environmental exploitability and continuous enforcement. Powered by Asimily Labs, ATT&CK Analysis isolates exploitable vulnerabilities per device, Risk Simulator models remediation outcomes, and Segmentation Orchestration generates, simulates, and enforces zero-trust policies. Asimily further extends risk mitigation with automated IoT Patching, centralized password management, and Configuration Control snapshots for IoT, OT, and IoMT devices.
