anything lost by running the older standalone SSL VPN client over the newer FORTIClient 

on newer windows 10 machines?

we don't have forticlient licenses and all the banner etc.. are very confusing for our remote users.

We really like the plain old vanilla VPN only client and are just wondering if we are loosing out on anything performance or otherwise by using the older client such as sslvpnclient_win_4.4.2276
