Most financial firms have decent lockdown... Generally firewalls prevent file sharing sites, web mail, connecting to any external port that's not http or https. I've seen some places prevent direct IP connections (need a hostname to connect). USB and SD card slots are disabled... Not to say that there still aren't dozens of ways to get around all this if you really wanted to.
