SecureCRT is a GUI-based telnet client and terminal emulator which started out life as CRT, which was released in the autumn of 1995.[3][4] Originally released as a premium version of CRT with support for SSH encryption, SecureCRT later replaced the CRT product entirely. These programs are part of a line of networking software which includes SecureFX, a file transfer client with SSL capability which replaced their earlier AbsoluteFTP product and VShell, which is a 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 of the above are commercialware.
