About Lansweeper

Lansweeper sells software that gives IT and Security teams one shared view across IT, OT, cloud, and AI.[3]

Lansweeper describes organizations that assume they have visibility until they need reliable answers from an auditor, a regulator, a cyber insurer, or a NIS2 or DORA reporting deadline. Lansweeper discovers assets across IT, OT, cloud, and IoT. Lansweeper normalizes duplicate and conflicting records into one asset record. Lansweeper enriches each asset with lifecycle stage, vulnerability context, and risk scoring. Lansweeper delivers data to ITSM, CMDB, and security tools so they are working from current data.[3]

Lansweeper applies context, vulnerability data, and lifecycle signals to assess risk, forecast spend, and surface optimization opportunities. Lansweeper supports continuously verifying control coverage, detecting drift, and surfacing exposure before it becomes an incident. Lansweeper turns security findings into structured IT workflows with clear ownership, context, and end-to-end tracking.[3]

Lansweeper runs several discovery systems and then recognizes, reconciles, and revalidates everything they find. Lansweeper uses three systems for the three places assets live: the network including OT, off-network laptops, and cloud. Passive detection runs by default in Lansweeper, so devices appear even if they never answer a scan. Lansweeper matches devices on MAC, serial, and hostname, never IP, and merges them into one record that lists every contributing source. Lansweeper evaluates new scans against existing records continuously, not on a quarterly cycle.[3]

Affected Product Categorization organizes vulnerabilities according to their root causes and affected products. Affected Product Categorization fields can be used to filter, group, and sort vulnerabilities.[4]

The Free plan scans the full environment with no asset cap, and every discovered asset appears in the inventory. A paid Lansweeper Platform plan includes features the Free plan does not, such as creating dashboards and exporting views. Enterprise is the highest Lansweeper Platform plan, and some features are available only on Enterprise. The Self-Service Subscription Management Portal is a single place to manage a Lansweeper subscription, billing, payments, and invoices, without contacting a sales representative. From November 5, 2026, monitors become billable and count toward a Lansweeper plan like any other asset.[4][5][6][7]

Lansweeper offers a ServiceDesk Plus connector that manages assets and configuration items for integrations. Lansweeper offers a Customer.io connector that creates, deletes, and tracks customers on the Customer.io platform through the Track API. Lansweeper can send emails in the context of the helpdesk module and can send report and event alerts. Lansweeper lets users create specific SLAs for specific ticket types, priorities, sources or users. To use Microsoft 365 with modern authentication as a mail provider in Lansweeper, a Microsoft Cloud Services application is required.[2][4][5][6][8][9][10][11]
