Armis vs Axonius: asset inventory facts side by side

SHORT ANSWER

Armis describes 4 of the five approaches on the pages we read and Axonius describes 3; they differ on CAASM aggregation and Agent-based inventory. On collection, Armis works without new agents and Axonius works without new agents. Many estates run two of these approaches together, so the question is often which pair, not which one; we do not score either.

Fact	Armis Centrix	Axonius
Positioning	Armis calls Centrix a Cyber Exposure Management Platform. It builds an inventory of IT, OT, IoT and medical devices from agentless, passive discovery and adds modules for prioritization and remediation.	Axonius grew out of cyber asset attack surface management (CAASM) into a broader asset intelligence platform. Axonius describes the Axonius Asset Cloud: it connects to the tools a company already runs through adapters (its directory lists 1,306), correlates what each one reports into one record per asset, and acts on gaps through workflows and bi-directional integrations.

Can they work together?

Neither vendor's pages we read name the other as an integration. That does not mean they cannot work together; ask both vendors.

Choose Armis if

Your estate includes OT, IoT or medical devices that cannot take an agent
You want device discovery and exposure modules from one vendor that is now part of ServiceNow

Choose Axonius if

You already run many security and IT tools and they disagree about what exists
You need SaaS apps and identities in the same inventory as devices, with workflows to close gaps

Which limits should you check?

Armis

No price on armis.com; the only public figure is an AWS Marketplace minimum.
SaaS applications and identities are not described as asset classes on the pages we read.
Prioritization and remediation sit in separately named modules.

Axonius

Coverage depends on the tools you connect: each adapter needs API access and credentials, and no agent or native network scanner of its own is described.
External (internet-facing) discovery is not described on the pages we read.
No free tier or trial is listed on the pages we read, and the AWS Marketplace listing prices 500 assets at $90,625 for 12 months.
