7 Best SSH Clients for Windows (Putty Alternatives)

When we need to remotely connect the computer by using a secure protected channel, SSH is truly the standard. PuTTy is the most widely used and popularly best SSH client for Windows-based systems as it is user-friendly. But first let’s understand all about SSH.


What is SSH?

SSH abbreviates for Secure Shell or Secure Socket Shell. It is a network protocol that provides users, mainly system administrators, a better and secure way to access a computer as compared to an unsecured network.

The first version of SSH was designed by Tatu Ylönen in 1995. SSH refers to the set of utilities that carry out the SSH protocol. SSH creates strong authentication and encrypted data communications between two computers connecting over an open network such as the internet.

SSH is commonly used by network administrators for managing systems and applications remotely, authorizing them to log into another computer over a network, implement commands as well as move files from one computer to another.

SSH-2 is the current version of Secure Shell protocols. It was adopted as a Standards Track specification by the Internet Engineering Task Force (IETF) in 2006. But SSH-2 is not compatible with SSH-1.


Why PuTTY is widely used for Windows?

PuTTY has been in practice for decades now. It has been the best SSH client in the Windows world since it is small in size and can be easily accessed. It manages Cisco Routers, logs into the VPS or Cloud Server which makes PuTTY, the favorite choice of many Network Engineers and server admins for configuring the SSH enabled devices.

Besides, it helps to log into another computer, which may be on the same network. The basic program is not secured, however, combining it with SSH adds on authentication and encryption to protect connections across the internet.

PuTTY is released under the MIT license which, not only preserves the author’s copyright but also allows any other developer to use the source code (which is publicly available) and develop other software from it. The tool also contains a file transfer facility, which can be secured by adding in SCP and SFTP.

But there are tools other than PuTTY which have more features to manage servers over SSH remotely. Since the quality of network software has become quite advanced over the past few years, we have a lot of tools which can overcome PuTTY’s missing features such as its inability to open sessions in tabs.

PuTTY is not the only SSH client for the Windows-based system and there is a long list of alternatives that offer even more features and are free to access.
