SSTP Connect is a VPN client that supports two HTTPS-based protocols, SSTP and SoftEther VPN.
SSTP (MS-SSTP) is developed by Microsoft and supported on Windows Server 2008 and later. It encapsulates IP traffic (layer 3) over HTTPS.
SoftEther VPN is developed by Daiyuu Nobori and SoftEther Corporation. It encapsulates Ethernet frames (layer 2) over HTTPS.
This is a third-party implementation based on Microsoft Open Specifications and SoftEther VPN source code. We do not have any affiliation with either Microsoft Corporation or SoftEther Corporation.
