What We Do

Managing IT has never been a bigger challenge. Hardware, software, and users can be anywhere at any time, making IT environments extremely dynamic and often complex. A seemingly simple question has become terribly difficult to answer: ‘Who is using what device?’

IT managers have to make decisions that are often based on scattered, out of date, and incomplete data sources. How can you effectively manage the IT of an organization, if you’re not 100% sure of what assets you have to manage in the first place?

This question inspired Lansweeper and still drives us today. We believe that answering it is crucial to tackle and simplify many of the challenges IT professionals face every day.

Centralized IT Asset Data enables every stakeholder who needs insights into your company’s IT landscape to speak the same language.​ Connecting and centralizing IT Asset Data to collaborate across silos, locations, and departments is essential.

Eliminate the blind spots from your environment and discover assets you didn't even know about. Lansweeper's IT Inventory Platform provides you the means to achieve complete visibility into your IT, centralized into one solution, helping you gain an in-depth understanding of your entire IT estate.

Lansweeper creates a substantial reduction in the measure of time IT teams would ordinarily spend on routine, yet key assignments, such as network discovery, inventory, software distribution, licensing and updates. This task automation is critical for organizations with restricted staff and IT spending plans. Reveal needless expenses, support budgeting decisions, and manage your IT cost-effectively with Lansweeper

The basic premise of good cybersecurity is that you can’t protect what you can’t see. So the critical first step when it comes to basic cyber hygiene is to maintain visibility of your IT environments and develop the relevant daily routines to inspect and verify.
