About Us

SSHTOOLS is a small team of developers that has been the leading provider of secure, enterprise grade Java SSH APIs for over a decade. In 2002 our founder Lee David Painter developed J2SSH the original open source SSH API. The projects success lead to the foundation of 3SP Ltd and the development of a second generation commercial API and the birth of another open source product called SSL-Explorer, a browser based SSL VPN.

3SP Ltd was acquired in 2008 by Barrracuda Networks for the SSL-Explorer technology and SSHTOOLS Limited was incorporated to continue development and support of the SSH API products under the original management and ownership.

In April 2015, SSHTOOLS Limited merged its operations with Hypersocket Software Limited a new company under the stewardship of Lee David Painter. SSHTOOLS and the domain sshtools.com continues to be operated as a separate brand by Hypersocket Software.


Having recently open sourced the second generation API under the LGPL, the team are now working towards a third generation unified API built around NIO called Maverick NG. The team are also involved in commercial projects on behalf of clients and have founded a new open source project the Hypersocket Framework which has already spawned a number of new products under Hypersocket Software brand.
