Asset census: compare CAASM and asset inventory vendors in columns
SHORT ANSWER
Pick two to five vendors to see the facts we record for each in one table: the five approaches, fifteen practical checks, the platform each belongs to, integrations and pricing. The table has no scores; rows where the vendors differ are tagged. It opens with the first three vendors in alphabetical order.

|---|---|---|---|
| Approaches at a glance | |||
| 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. | Censys's external exposure management product, built on first-party scanning of all 65K ports and the Censys Internet Map. |

Questions people ask
Why can I only pick five?
Beyond five columns the table stops being readable on a laptop. Use the platform notes for the full detail on each.
Why is there no total or score?
We do not score vendors. The table shows recorded facts; the finder applies your own constraints.
Can I share a comparison?
Yes. The selection is in the address bar, so copy the URL.
