There are now many different VPN services available online, however the vast majority of these are very basic systems simply designed to bypass the blocks on watching media sites in different countries.
If you want more than this, to provide real security through a network of ultra secure servers then your choice becomes much more limited. This video demonstrates one of the most sophisticated VPN solutions available to personal individuals.
You can control what is encrypted, switch between countries automatically and even adjust which applications are cloaked individually. For advanced users there is the facility to enable cloaking in a corporate environment, through an internal proxy - most VPN software will simply not work in this environment.
