Putty (free download) has ssh connection.
SecureCRT works well too, and many companies have it available for other applications they use and maintain. Check with your IT department.
Remember that if you have Windows 10, the Ubuntu Linux shell has a SSH client built in to it as well.
Like x-man recommends though, Putty is kind of the "industry standard" here... Most companies like Mitel, Avaya, Broadsoft, Adtran, etc. use "putty" and ssh almost interchangeably, like saying Q-tips for all cotton swabs, except they will say "just putty into it".
