Price: proXPN has a free plan, which limits your transfer speeds to 300kpbs and restricts you to one exit location (Miami) in the United States. Premium accounts unlock support for PPTP (if you want to connect a mobile device or a router,) remove the transfer cap, and allows you to choose from any of the company’s other exit locations. Premium plans start at $10/mo, and you can read more about their pricing and plans here.
If your VPN provider is based within a country that is part of the 14 Eyes, it can be asked to share data of its customers and will legally have to comply. If your provider promises that it doesn't log any information, you're probably safe within the 14 Eyes, but it is more of a risk if privacy is your main concern and you might want to consider looking for a VPN provider that is based elsewhere.
Switzerland is famed for its privacy-friendly legislation, and that’s where VyprVPN operates from - although its servers operate in 72 other countries to deliver unlimited data. If you’re used to VPN services absolutely killing your data speeds you’ll be positively surprised by VyprVPN: we found that our data speeds actually increased when we enabled the VPN! Not only that but there are plenty of useful options including auto-connect, a kill-switch and enhanced security via the service’s proprietary Chameleon protocol and its own DNS. VyprVPN has a free trial too so you can try it our and see what you think before you commit!
Avast SecureLine is also expensive, and based on current speed results for the UK and U.S., you’re probably better off shopping around for a better deal; SecureLine works out at £49.99 a year for a single device (equivalent to £4.17 a month). If you want to connect more than one computer or mobile device, a five-licence account will cost you £64.99 a year.
