Always Use A VPN On Shared Wifi Networks
You may not be aware, but there are serious security issues regarding public wifi networks like the ones that you find in hotels. When you connect to a hotel wifi network, you join the same network as many other users who are also staying in the hotel (or spending time in the hotel lobby). While most networks will have security measures in place to guard against outside attacks, far fewer have countermeasures set to protect a network’s own users against each other. It is possible for other users on your network to intercept your data, which can lead to identity theft or having your credit card information stolen.

Another problem is honeypot wifi networks. This is when hackers set up a fake wifi network which does not require a password to access. When users connect to the network, they can access the internet and everything appears to be normal. But then when they send their usernames, passwords, and other information over the internet, this data can then be stolen by the scammers running the honeypot.

Further risks of using an unencrypted public wifi network include becoming a victim of a phishing or vishing attack, as your IP address reveals your location, making you easier to target. To top it all off, whenever you use an unencrypted connection, all of your internet activities are visible to the ISP running the connection. In order to keep your data private when you browse the internet, you need to ensure that you use a VPN to encrypt all of the data that you send (key word is send, GuardedID and MobileTrust encrypt the Keystroke at the kernel level preventing the stealing of information by keyloggers who get it all before you hit send making VPN's ineffective when your device is already hacked and thus the VPN is unable to prevent the keylogger from getting your private information) over public wifi networks.
