Wingpath to cease trading on 25 October 2025

From 25 October 2025 we will no longer be selling licences for our software products (ModSnmp, ModMultiSim, Modsak, ModSlaveSim, ModMaster and ModTest).

The website will remain operational until at least 2027 for reference purposes, and for the registration and transfer of product licences.
