Lansweeper

Lansweeper builds an IT asset discovery platform that scans networks — on-prem, cloud, OT, and remote endpoints — to build a continuously updated inventory of hardware, software, and configuration data. The premise is direct: security and IT teams cannot patch, segment, or protect what they do not know exists, and unmanaged or shadow devices are a recurring root cause in breach post-mortems. Lansweeper positions the resulting inventory as the foundation layer for vulnerability management, compliance reporting, and attack surface reduction programs run by other tools downstream.

Founded in 2004 and headquartered in Dendermonde, Belgium, Lansweeper has scaled well past its original on-prem IT-asset-management roots, counting large enterprise customers including IBM, Allianz, Samsung, Nestlé, and Maersk. In July 2025, it acquired Redjack, a passive network traffic analysis company, to add agentless, non-intrusive discovery for OT and hard-to-scan environments — a direct extension of the core discovery mission into attack surface management territory.

The company took a majority investment from private equity firm Dovesco in 2018 and later raised roughly $158M (€130M) from Insight Partners to fund platform expansion. That level of institutional backing, combined with a genuine acquisition track record, suggests Lansweeper is consolidating the asset-discovery-to-attack-surface-management pipeline rather than staying a niche IT inventory tool.
