It is often underestimated how unsafe using the Internet can be in a public place, by those who lack a basic concept of security. It is, however, no large feat to simply swipe the information that someone might be sending out of the air, and anyone using the same WiFi network as you can do so with relative ease.
The easiest way to protect your data as it travels is by using a Virtual Private Network (VPN). This takes your data and encrypts it, and then sends it on its way. The data is decrypted before being given to it’s destination. This helps to prevent anyone from simple sitting in the same setting as you and stealing your information. It makes bank transactions, online purchases, and social networking (just to name a few) a lot more safe and reliable.
