Hello, From my expirience 1 average user can do about 100 connection max. When i deployed PA equipment it was usually 60-80 connections from 1 user. So PA 220 should be enough because this model can work with 64,000 sessions. There are some exceptions if your company does not trade. Traiding software makes a lot of sessions. In my company about 30 people and i use all functionality and load about 2000 sessions. Best regards, Roman
