To understand whether you need a VPN
, consider the following scenarios in which a VPN might be used. Let's say you are using the public Wi-Fi network, perhaps at an airport or a coffee shop. Normally, you would connect without any hesitation, right?
Now, can you tell who might be watching the traffic on that network? How sure can you be the Wi-Fi network is even legit or it is not operated by a hacker who's after your private data? Just think about the passwords, credit card numbers, banking data, and just plain personal information that you transmit every time you go online.
On the other hand, if you connect to that same public Wi-Fi network using a VPN
you can rest assured that no one on that network will be able to intercept your data. Everyone should keep in mind that it's very difficult to tell whether the Wi-Fi network you are connected to is operated reliably and it is not "offered" by somebody else. If a thief names the spot "MacDonald's Wi-fi" that doesn't mean you are really connected to a MacDonald's' network.
Usually, you don't have to worry about that when you're at home. Since you own the Wi-Fi network--you have control over it. Still, using a VPN
can be helpful here, too. Did you know that your internet service provider (ISP) has enormous capabilities to see what you do online? Besides, this personalized data can be transferred further to some governmental institutions per request whether in exchange for money or simply because of a law.
I'm not saying you have to be paranoiac about it but caring about your data security is a nowadays rule of thumb, don't you think?
Anyway, having so many quality VPN providers available
, securing your online-being is not an issue anymore.
