Here is a guide on how you can use Access*One in combination of PocketPUTTY or PUTTY to be able to use the secuirty tunneling proxy built into PUTTY. For instance can this be used to communicate over SSH which is becoming more and more popular.
In a coming release of Access*One (not decided yet) security will be built in directly into the client software itself. For the time being the PUTTY + Access*One solution is both cost effective and efficient.
