Public Wi-Fi and insecure connections are bad news if you value privacy. The solution is to use a VPN such as proXPN, and TechnoBuffalo Deals has lifetime subscriptions with unlimited traffic for $39.
This service uses fast servers around the world to mask your online identity without causing lag. The global presence both speeds up your connection and gives you the opportunity to access region-locked content, such as Netflix and Skype. For added security, you can choose to deploy 512-bit encryption, which uses a mighty 2048-bit encryption key. You have a choice of two protocols — OpenVPN and PPTP — and VPN Guard allows you to choose what should happen if your secure connection drops. You can use proXPN on all major desktop and mobile platforms, and you get comprehensive support.
The deal takes 89% off the regular price of a proXPN Premium lifetime subscription.
