Mac/iOS: Connecting to open Wi-Fi networks, like those in cafes, can leave you open to all sorts of attacks. To keep your personal information safe, free app Cloak encrypts and re-routes all your traffic through a VPN whenever you connect to a public Wi-Fi network.
There are a lot of things you can do to stay safe on public Wi-Fi networks, like using HTTPS whenever possible. One of the best ways to secure your browsing is with a virtual private network, though that can take a lot of work to set up. Cloak makes the process as dead simple as it could possibly be: whenever you're connected to an open Wi-Fi network, it connects you to its VPN service for totally secure browsing. It could not be any simpler to use.
All you need to do is sign up for Cloak's service here, then download and install Cloak on your Mac. After you log in, it sits in your menu bar and waits for open Wi-Fi networks, securing you when you connect to one. If you have an iOS device, you can install the mobile app and just flip a switch in your device's settings to turn the VPN on. You can use the service for free for up to two hours or 2GB per month, whichever comes first -- which isn't that bad for most of us. For those of you that frequent coffee shops a bit more often, you can upgrade your account to a premium one, starting at an inexpensive $US8 a month.
Cloak itself is a free download for Mac, iPhone and iPad. Hit the link below to read more and download the app.
