Hotspot Shield is a free software that allows you not only to secure your connection while surfing wifi hotspots, but also to access sites not normally available outside of the USA.
To secure your Internet connection, Hotspot Shield creates a Virtual Private Network (a secure connection, usually abbreviated to VPN) between your computer and the developer's website Anchorfree, based in the USA.
Hotspot shield is extremely useful for keeping online security. It keeps me safe from the threat of phishing. But, Hotspot shield is not a comprehensive security solution as it does not provide offline data security. In order to maintain my offline security, I use encryption software Folder Lock that makes my data perfectly secure.
