SecureCRT is a commercial SSH and Telnet client and terminal emulator by VanDyke Software. Originally a Windows product, VanDyke later added a Mac OS X version in 2010 with release v6.6^[3][4] and a Linux version in 2011 with release v6.7.^[5]

SecureCRT is a GUI-based telnet client and terminal emulator originally called CRT. It was first released in the autumn of 1995 by VanDyke Software.^[6][7] Originally released as a premium version of CRT with support for SSH encryption, SecureCRT later absorbed the CRT product entirely. The program is part of a line of networking software which includes SecureFX, a file transfer client with SSL capability, and VShell, an SSH server.

SecureCRT and SecureFX can be started from within each other and use a combined host information list. A separately-sold pack of command-line tools (e.g., scp, modeled after the Unix command of the same name) for use with VShell is also sold by the company. All offerings are commercialware.
