Integrate Lansweeper with SCCM
Benefits
Lansweeper can scan machines that are visible in the Assets & Compliance > Devices section of your SCCM server and cross-reference them with Lansweeper assets. Scanned SCCM data includes device name, domain, IP address, manufacturer, model, operating system, processor, memory, resource ID, serial number, site, client details, network adapters, software and more.
Lansweeper assets are also automatically created for any Windows, Linux and Mac computers that are found in SCCM and that were not previously found by Lansweeper.
