Since the gigantic development in the virtual world of world wide web, securing the corporate network had been one of the biggest challenge that many corporation are facing. In the search of the solution computer science have found the number of solution among them Secure Shell (SSH) is one of the best. SSH (Secure Shell) is a most popular, robust, TCP/IP-based product for network security and privacy, supporting strong encryption and authentication. Basically SSH (Secure Shell) is a secure, robust protocol for creating a secure connection between two computers. One of the major features of SSH is its encryption and authentication features. SSH is implemented with strong encryption technique to make it safe from different kinds of threats that network posses, In addition to encryption, Authentication feature make it even more secure than traditional telnet application. SSH protocol is almost like a telnet application but the major difference comes in way it transmit the data. The SSH protocol is defined by the IETF Secure Shell Working Group (secsh). SSH was designed as a replacement for the legacy telnet application. In other to connect between two computers using SSH both computer need SSH application. The computer being connected to must be running an SSH daemon, or server process and the computer which is attempting to connect must be running an SSH client.

There are quite a few companies that provide all these services to clients who needs it. Pragmasys is one of the companies that provides SSH servers and clients for people who need it. There are some companies that also require SFTP client for data transfers. SFTP- full form, Secure File Transfer Protocol is used to transfer files, it is just an advanced version of FTP (The regular File Transfer Protocol). Companies can use regular FTP to transfer files from one computer to another but there are some drawback to it. Here are some features of SFTP which are not available in FTP.

• Uses encryption while transferring files
• Uses Port 21
• MD5 encryption algorithm is used (This creates a checksum to make sure that file is not corrupt)
• Uses secure channel for transferring files

Pragmasys provides a very secure platform for SSH and Telnet servers. They provide one of the most secure server products for Windows operating systems. Now they have started providing 64Bit encrypted SSH servers. Pragmasys is one of the leading SSH server providers in the industry and their FortressSSH system has both high priced and low priced ones depending on your needs.
