VPN
Whether using the free wifi at the local cafe or traveling abroad, a VPN can help protect your computer from those hoping to violate your privacy or access your data. A VPN, or virtual private network, is a technology that establishes a secure tunnel between two or more devices. While often claiming to do so, VPNs do not give you total anonymity online and should not be used to achieve this. They do, however, give you increased privacy and also help you to access content blocked in your region.
Use: Whenever you're connected to the internet. Most importantly when on any public wifi.
