What K2 KeyServer is
K2 KeyServer combines hardware and software inventories with purchase histories, usage records, and software license management. Its client discovers hardware details and installed software on Windows, Mac, and Linux computers, including virtual machines and thin clients. Hardware tracking follows computers, mobile devices, printers, and networking devices from order through disposal. The platform records operating-system logins, software launches, and defined cloud product usage, and can compare usage reports with purchased entitlements. It supports spreadsheet imports and data exchange through REST API, ODBC, JDBC, and JSON, with integrations for TeamDynamix, ServiceNow, and Modo. Organizations can run it on-premises or use Sassafras’s cloud hosting environment. A server process supports up to 70,000 Windows, Macintosh, and VDI computers. Subscriptions include setup assistance, technical support, and an annual configuration review. Pricing is available on request, and a free evaluation is offered. The REST API is intended for basic queries, not bulk or heavy-use retrieval.
