Armis vs runZero: asset inventory facts side by side

SHORT ANSWER

Armis describes 4 of the five approaches on the pages we read and runZero describes 3; they differ on CAASM aggregation and Exposure management. On collection, Armis works without new agents and runZero 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.

How do their approaches compare?

Top bar: Armis Centrix

Full bar: described on the vendor's pages we read
Hatched bar: described with a condition (another product, a higher tier, or part of the approach)
Stub: not in our sources (it may exist; we did not find it)

The bars show what each vendor's own pages describe, or how your answers weigh the five approaches. They are not a measure of how well a product works.

What are the facts, side by side?

From each vendor's own pages. Differs marks rows where the recorded status or check value differs.
Fact	Armis Centrix	runZero
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.	An asset discovery platform that runZero describes as CAASM: active scanning, passive discovery for fragile OT networks and integrations, with each asset profiled against nearly 1,000 attributes.
