Bitvise is a team of programmers specializing in security software mainly for the Windows platform. It’s main products are WinSSHD and Tunnelier, which were developed to be the best SSH client and server for Windows.
Bitvise began in early 2000 with the idea to develop an SSH server for Windows, which at that time was not available on the market. Bitvise began with two and has grown over time to a size between four and six people. Most of them are developers, living in different countries. Bitvise’s plans for the future remain simple: do it’s best to produce robust and reliable security software.
In May 2002, Bitvise released the first WinSSHD and Tunnelier in the 3-series, with Tunnelier now supporting the bvterm remote console and remote WinSSHD configuration. Another year later, in May 2003, Bitvise released new versions of our products with drastic improvements in speed, and in February 2004 Bitvise released the first versions in the 3.2x series, with xterm, VT-100 and graphical SFTP support available for the first time in Tunnelier. On 24 December 2004, Tunnelier 3.60 was released with dynamic tunneling, proxy and public key support, as well as a new license policy granting free individual use.
Years 2005 to 2007 featured WinSSHD and Tunnelier versions 4. In a process of incremental improvement, Bitvise products reached feature maturity and became known for their solidity and reliability, rooted in years of refinement.
2008 and 2009 saw the long-awaited release of WinSSHD version 5, featuring a complete rewrite of most of its functionality, including much better terminal and file transfer subsystems, fully FIPS 140-2 compliant encryption, and a new Control Panel. All shortcomings of previous releases that were caused by architectural deficiencies have been addressed in this version.
The licensing of Bitvise’s SSH technology has also played a role throughout this time. Each year, new clients trusted the SSH implementation with their network transport security requirements. WinSSHD 4 now even forms the core of a major competitive SSH server product.
