JupiterOne vs Tenable: asset inventory facts side by side

SHORT ANSWER

JupiterOne describes 2 of the five approaches on the pages we read and Tenable describes 3; they differ on CAASM aggregation, External attack surface management and Exposure management. On collection, JupiterOne works without new agents and Tenable does not describe its collection method on the pages we read. 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: JupiterOne
Lower bar, lighter: Tenable One

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.

Choose JupiterOne if

You want to ask relationship questions across assets, users and code
You need a published price before a sales call
