About Us

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. The company was formally founded in February 2001, and the first version of WinSSHD (now Bitvise SSH Server) was released in May. The initial version of Tunnelier (now Bitvise SSH Client) was released shortly thereafter - it supported manual port forwarding.

In May 2002, we 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, we released new versions of our products with drastic improvements in speed, and in February 2004 we 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, our 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. Most shortcomings of previous releases that were caused by architectural deficiencies were addressed in this version.

In 2012, we renamed our products to Bitvise SSH Server and Bitvise SSH Client, and released an important new version of our SSH Server, 5.50, with a complete authentication overhaul, support for true password-less login, and improved support for domain environments.

We released Bitvise SSH Server version 6 in 2013, with support for master/slave synchronization as the major new feature. Bitvise SSH Client version 6 was released in 2014, adding new command line clients and fully FIPS 140-2 compliant encryption.

The licensing of our SSH technology has also played a role throughout this time. Each year, new clients trusted our SSH implementation with their network transport security requirements. WinSSHD 4 even formed the core of a major competitive SSH server product.

Our company began with two and has grown over time to a size between four and six people. All of us are developers, living in different countries. denis bider, director and co-founder, lives in Costa Rica, but is originally from Slovenia, a small European Union country south of Austria and east of Italy. Another Bitvise co-founder lives in Seattle, Washington, USA. All of us developers work from individual home offices in Slovenia, Germany, and Costa Rica.

Our plans for the future remain simple: do our best to produce robust and reliable security software!
