Secure web tunnelling advise sought

I'm on the road constantly using WiFi hotspots and hotel room internet access. I'd like to have a higher level of security not just for the data/passwords but also to have the IPs and URLs of my browsing hidden. The company I work for had some illegal access to their servers a few years ago and suffered a large financial hit because of it. Obviously security is now a prime concern for them and I don't want to be the source of any leak. This is my main reason for wanting to do this but additionally I do invest online, bank online etc. I have been using a service; www.secure-tunnel.com that works quite well - when it works. I am posting this to explore other options for anonymous/higher security on-the-road internet access.
