Thanks compufunk for your input. Better late than never.
I am sure that it will help others as it gives few more applications to consider.
As my need is for a small business and not for personal use, I needed the licenses anyway and I am glad I chose ZoneAlarm in the end.
Testing more applications would be fun, but it is time consuming and as time means money, there is no point in testing more applications as it also mean uninstalling it before putting a new one in (for two computers !!).
So I had to draw a line today.
