If you’re logging on to a wifi network in a coffee shop or hotel, that network may not be secure. In extreme cases, it’s possible that a nefarious party could have set up a network to steal personal data. This could be passwords, credit card details or even just the email you’re sending.
With a VPN (virtual private network) in place, however, neither those operating the network nor those trying to hack into it can intercept your data, keeping private messages secure.
