Technology
Development
The software is developed and published by Bitvise Limited. The first released product was Bitvise SSH Server, then named WinSSHD, in 2001, and it was shortly followed by Tunnelier, now Bitvise SSH Client. There have been 8 major releases of the software so far.[5]
Features
Both the server and client work with all desktop and server versions of Windows and allow for remote-based access using a tool like WinVNC.[6] They provide a GUI as well as command-line interface to support SFTP, SSH, SCP, and VPN using the TCP/IP tunneling feature.[7][8][9]
The software among other supports GSSAPI-enabled Kerberos 5 exchange and NTLM Kerberos 5 user authentication.[10] It provides two-factor authentication and compatibility with RFC 6238 authenticator apps.[11]
Controversies
Bitvise owns and manages the domain putty.org which references to PuTTY, another SSH client for Windows. For many years, it linked to the official PuTTY distribution page along with promoting Bitvise's products. However, in July 2025 after being asked about this, Bitvise replied by posting the full email conversation,[12] ignoring the anonymisation requests with a "Lol You fucking idiot." reply.[13] After that, the putty.org website changed its contents to promote anti-vaccine theories.[14][15]
