Armis vs Asimily (2026)
Breadth against depth, and the buyer profile decides it. Armis is the horizontal platform: IT, OT, IoT, IoMT, cloud, and code across many industries, with medical device security as one of five products, the widest coverage in the lane and the only vendor offering on premise, cloud, and hybrid deployment, backed by consecutive Gartner Magic Quadrant Leader placement. Asimily is the healthcare specialist: ranked first in the 2026 KLAS Healthcare IoT Security report at 96.6, with contextual vulnerability prioritisation and pre purchase device evaluation that most competitors do not offer. The trade Armis makes is healthcare specific depth for platform breadth, which independent Gartner Peer Insights commentary notes in observing that its OT and CPS protocol depth is not top tier. If your failure mode is a health system that also runs industrial plant and wants one platform across all of it, start with Armis. If your failure mode is the deepest clinical device intelligence with the top independent healthcare rating, start with Asimily.
- One platform across everything you run: IT, OT, IoT, IoMT, cloud, and code across healthcare, manufacturing, energy, and government, graded A on setting coverage, a genuine consolidation argument for a health system that also operates industrial plant and building management.
- The only deployment flexibility in the lane: on premise, cloud, and hybrid, graded A on deployment, where Asimily is cloud only, which matters for organisations with data sovereignty constraints.
- The strongest analyst position: named a Leader in the 2026 Gartner Magic Quadrant for CPS Protection Platforms for the second consecutive year among 13 vendors evaluated.
- The top independent healthcare rating: ranked first in the KLAS 2026 Healthcare IoT Security report at 96.6, buyer sourced research from actual health system users, where Armis holds Gartner CPS recognition but no healthcare KLAS ranking was located.
- Depth over breadth on clinical devices: contextual vulnerability prioritisation that evaluates each vulnerability against the specific device configuration and network environment, plus pre purchase device evaluation that moves risk assessment upstream of procurement.
- The integration that connects security to the people who fix devices: bidirectional CMMS linkage including MediMizer, graded A on interoperability, feeding security incidents into the biomedical engineering remediation workflow.
This comparison is published by AI Health Index, an independent research platform that compares healthcare AI vendors objectively. Armis and Asimily are each graded against the same capability taxonomy, from each vendor's own public materials and the regulatory record, under the AI Health Index verification standard. No vendor pays for placement, and no vendor has reviewed this page. How this evidence is graded

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Armis its top capability grade on several axes, including Security Certifications and Trust Center, EHR and Interoperability Depth and Deployment Model and Data Residency. Set against Asimily, Armis grades higher on several axes, including Model Supply Chain Disclosure, Security Certifications and Trust Center and AI Governance and Bias Disclosure. Its thinnest published disclosure sits on AI Liability and Recourse. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Armis or Asimily?
On the axes where the AI Health Index separates them, Armis grades higher on several axes, including Model Supply Chain Disclosure, Security Certifications and Trust Center and AI Governance and Bias Disclosure, and Asimily grades higher on several axes, including Model and Technology Transparency, HIPAA and BAA Posture and FDA and Regulatory Status. Neither leads on the greater share of scored axes, so the decision turns on which constraint is binding rather than on an overall winner.
Where do Armis and Asimily differ most?
The widest separation the AI Health Index records between Armis and Asimily is on HIPAA and BAA Posture, where Armis grades C and Asimily grades A. That axis sits in the Regulatory and Compliance group, so it should carry the most weight for a buyer whose binding constraint is where regulatory exposure sits and who carries it.
Where do Armis and Asimily grade the same?
The AI Health Index grades Armis and Asimily the same on several axes, including AI Centrality, Autonomy and Oversight Model and Clinical and Operational Evidence. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.
What have Armis and Asimily not disclosed?
At the last review, at least one of Armis and Asimily published thin or absent detail on AI Liability and Recourse. The AI Health Index treats an absent disclosure as a gap in the public record rather than a failure of the product, so these are the axes to get in writing during diligence instead of inferring from the grade.

Both grade B on AI centrality, but for different reasons this index states plainly: Armis because medical device security is one of five products on a horizontal platform whose centre of gravity is cyber physical systems broadly, and Asimily because its substantive moat is a curated knowledge base of device profiles rather than the model alone.
Armis grades C on model transparency for platform level language without a named detection methodology, where Asimily grades B. Neither publishes a security attestation such as SOC 2 Type II or ISO 27001, a pointed gap for security vendors and one shared by every vendor in this category. Armis has announced a planned acquisition by ServiceNow expected to complete in the second half of 2026; buyers signing multi year agreements should establish contractual continuity. Neither publishes pricing.
