Lansweeper vs Tenable: asset inventory facts side by side

SHORT ANSWER

Lansweeper describes 3 of the five approaches on the pages we read and Tenable describes 3; they differ on Agent-based inventory, External attack surface management, CMDB-centred inventory and Exposure management. On collection, Lansweeper offers its own agent and also works without one 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.

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 Lansweeper if

You want to find what is on the network yourself, including OT, without going through sales first
You need off-network laptops covered with a light, optional agent

Choose Tenable if

You already run Tenable vulnerability management
Your question is which exposures to fix first more than which assets exist

Which limits should you check?

Lansweeper

SaaS coverage is limited to AI usage tracking on the pages we read, and identities are not described.
Merging what many security tools report is not described; deduplication uses MAC address, serial number and hostname.

Tenable

Attack Surface Management and the Tenable One platform are demo only; free trials cover Vulnerability Management and Nessus.
A unified internal asset inventory, SaaS apps and identities are not described on the pages we read.
