You hear lots of people recommend using a VPN, but what does this VPN thing do for me?
In simple terms, a VPN creates a secure connection between you and your VPN provider. You are encrypting your data between the first half of your network connection. You’ll see below why you may want this.
When you connect to a free WiFi network, like in a coffee shop, hotel, live event, etc…, so can the bad guys. This makes it easy for these bad guys to be able to try to access your data and activity.
Here are a few thing they may try:
Using a VPN will put a security barrier around your connection while you access the internet on public networks.
Geo-blocking is a technology that restricts access to internet content based on the user’s geographical location. The location is determined by a number of factors, but the main way is checking the user’s IP address.
By using a VPN, you are able to select a location from where your VPN connection will access the internet. This will allow you to bypass some region locked services.
For example, BBC iPlayer is a streaming service to view BBC television but is restricted to UK-Based viewers. You might be able to use a VPN to get access to the service when you are outside of the UK.
Your ISP (Comcast, AT&T, etc…) is able to see what sites you are accessing. They don’t see exactly what you are doing because most websites use HTTPS, which encrypts the data.
But they can see the IP address of the site you are going to, so they’ll still know if you went to YouTube or your bank.
If you use a VPN, then they only see that you are going to the IP address of the VPN service. And they can’t see where you go through the VPN.
If you use public WiFi, then you should consider getting a VPN service.
If you mostly use your home, work, or cellular internet, then a VPN service is probably not something you need.
