How Does A VPN Work?
VPNs were first built for work. It allowed employees working from home or outside the office to access documents and files without jeopardizing office security.
What a VPN does is create a private address for you. It masks your actual IP address and connects you through the new address on the selected server location.
Then it connects you to the site or content you want to access, making the server location seem like your location. In doing this, you can access everything securely from your server location. This is how you can access blocked content.
At the same time, the VPN encrypts your data before connecting you to the server.
This is how VPNs provide security. Some can even provide an extra layer of security by redirecting your address twice.
This means your connection goes through two different servers. So if you are on a public network and use a VPN, you don’t have to worry about your information being leaked.
What Can You Use It For?
There are multiple ways a VPN can help you.
- Protect yourself on the internet – VPN services encrypt your data and save you from the prying eyes of third-parties on the internet. Some VPNs allow you to route through two servers, giving you double protection. This makes your digital activities even harder to trace.
- Get access to your office database – This is what VPN was originally developed for. Your office database is probably restricted to multiple security layers. When you work from home or use a public network, a VPN protects both your and your company’s information. Most businesses have designated VPN software for this purpose.
- Unblock geo-blocked sites – Geo-blocked sites are those that you do not have access to because of your geographic location. Not only does it limit you from using various websites, but it can also be a hassle when you are travelling. You can use a VPN to access these sites, that mostly fall in two categories:
- Media streaming – Online streaming services like Netflix, Hulu, Amazon Prime use geo-blocking to target their audiences. You can access their much larger libraries set for different locations using a VPN.
- Online shopping – If you want to order something from your country while on a trip abroad, you may find certain sites blocked. This is done so that local businesses can sell more goods and services. However, you can use a VPN to bypass this block and order online.
