Anyone who travels a lot, or uses "free WiFi" to connect and work on their laptops or even their smartphones, should definitely have a VPN service. This will protect your data from being stolen on these free WiFi networks. The reason why these free WiFi networks are an issue, is because they are unsecured. That means that anyone can grab data from you, since you are connected to the network. A big reason why many security researchers say to never log into your bank account on a free WiFi network. However, with a VPN, your traffic is encrypted so that your data will be safe and not stolen.
OneVPN is a great VPN to check out and you can get a lifetime subscription for just $29, which is a pretty amazing price. Unlike other VPN services, OneVPN does not slow down your speeds while you are using it and surfing the web. So even on a fast network, you won't even notice that you are connected to a VPN. OneVPN has 30 servers located in about 18 different countries, so no matter where you travel to, you'll be covered. When talking about encryption, OneVPN uses 256-bit to secure all of your personal data.
