Security at open public WIFI

When I use my notebook at free open public Wi-fi sites I use a vpn service provider (hotshield) for a more secure connection. I just download the software and click on the icon to activate. Is there a similar service that works with the playbook? I could not find anything in the appworld for this.

Strange...I would think that since RIM is in the server and security business that they would provide such a service to playbook owners.

Any advise to secure the playbook at public wifi would be appreciated.

You can set up VPN in the Security part of Options.
