Private Tunnel, from the makers of the open-source OpenVPN protocol, offers an affordable way to keep your Internet traffic safe and private.
Pay per byte: Private Tunnel embraces a different payment model than most other VPN services. Instead of subscribing for a period of time, you can purchase a set amount of transferred data: 20GB for $9.99 or 100GB for $19.99. The pay-as-you-go plans cover unlimited devices. A limitless data plan goes for $29.99 per year and includes 10 devices. To check out Private Tunnel, sign up for a new account to get a free 2GB trial.
Skirt regional limits: Private Tunnel offers a handful of exit nodes to get around georestrictions, including in Canada, Germany, Hong Kong, Netherlands, Sweden, Switzerland, United Kingdom, and United States.
Small hit on speed: In informal tests on Wi-Fi and cellular networks, Private Tunnel barely took a hit on network performance, and media streamed without a noticeable hitch. If you do experience connection issues, you can can switch to another transport protocol that Private Tunnel handles: UDP for a faster connection, TCP for more stability, or a proxy if you are behind a firewall. By default, the VPN uses its adaptive setting, which attempts to connect using the UDP protocol first and then tries the others.
Security: As you'd expect from the group that worked on the OpenVPN protocol, that's what Private Tunnel uses to secure connections, with 256-bit AES to encrypt data.
Personal information: Private Tunnel says that the only data it collects is related to billing -- including date, time, and data usage -- and it does not share user data with third parties.
Limited number of exit nodes: Private Tunnel hits many major locations with its server nodes but lacks the expansive list of other VPN services.
Private Tunnel finds a good balance between capabilities and price and should meet the needs of most anyone except those requiring an expansive list of exit nodes.
