What is VPN, and Why You Should Use it?.

VPNs are growing day by day and there are reasons to use them. In fact, because VPNs are easy to use, even for the average home user, they are no longer just for computer geeks or security experts. If you’re wondering, here are some of the reasons why and when you should use a VPN to secure your online communications.

What is a VPN service and how does it work?

A virtual private network, or VPN for short, is a simple service that encrypts your connections to and from the Internet. Along with encrypting your internet connection, a VPN can also mask your current location with the location of the VPN service provider. A VPN can do this by acting as an intermediary between you and the actual destination.

For example, if you are trying to access google.com, the request is first encrypted on your computer and sent to the provided VPN service. Here, the request is decrypted and forwarded to the real Google servers. As you can imagine, Google does not see that the request was made by you, but sees the VPN. When Google answers you, the VPN will encrypt the connection again and forward it to you.

How to use a VPN?

There are several ways to use a VPN. For instance –

1. You can download VPN software, available for both desktop and Chrome browser (we recommend TunnelBear) and then install it on your system like any other software. After that launch the software, you should see a connect button, click on it and all your connection traffic will now go through the encrypted tunnel.

2. If your company provides you with a VPN to connect to their private network outside the office; then you can create a new VPN connection in your device’s Wi-Fi settings. On Windows 10, type VPN in the Start menu and press Enter. A new window will open, here enter the server IP, username and password provided by your company. You can find similar settings in all other OSes.

3. You can also add VPN at the router level by entering the server IP and login credentials. This way, all devices connected to this router will have VPN enabled.

Why use a VPN service?

1. Hide your location and increase internet anonymity

The first and most obvious reason to use a VPN is to hide your current location and increase your online anonymity. As I said before, a VPN acts as an intermediary between you and the destination.

There can be any number of reasons why you might want to hide your whereabouts, for example – to avoid censorship, to exercise your freedom of speech without showing yourself, to stay out of prying eyes, or you are an informant, etc. The reason is that a good A VPN can offer all the anonymity you need.

However, not all VPNs are the same. Some VPNs actually log your details, such as your real IP address, mask IP address and time, VPN username, operating system, browser signature, etc. As required by law. So, if you don’t want others to track your data, make sure your VPN is not logging data. Typically, most VPNs will inform you ahead of time, but you can also get this information from their Privacy Policy.

2. To access geographically restricted sites and services

Besides masking your current location, you can also easily access geo-restricted websites and services using a VPN. For example, there are several services like Hulu, Netflix, HBO GO, Pandora, etc., or even some individual portions of those services that are only available to US customers. These restrictions can be due to several reasons, such as government laws, copyright issues, distribution rights, etc.

So, in situations like this, you can use a VPN to access these services or shows anywhere in the world. This feature is especially useful when you are traveling and want to access your favorite shows on Netflix. Of course, if streaming content is your primary purpose for using a VPN, make sure your VPN is optimized for that.

3. To encrypt internet access when using public WiFi

More often than not, most of us are unaware or ignore the fact that when using a public Wi-Fi hotspot or any other publicly available network (like hotels or restaurants), your data is at risk due to the terrible security they offer. In fact, using several high-tech yet easy-to-use free tools available on the Internet, anyone with a little tech-savvy can easily eavesdrop on your connection and steal your data or identity.

However, because the VPN encrypts all of your inbound and outbound connections, your communication remains secure. What’s more, a VPN makes it nearly impossible for a cracker to hack into your connection.

Note. Since most VPNs change your geographic location, some banking transactions may fail if they detect a large transaction from another country. Plus, since most financial services use 128-bit https encryption, you won’t need a VPN for this, even on a public network.

This is one of the most overlooked reasons, but you can actually use a VPN to access your home network over the Internet.

You will need a good and stable connection, of course. Not only your home network, but you can also set up a VPN to access your work or business network. In fact, most businesses and businesses use their own VPNs to give employees access to the corporate network.
