What Is A VPN And How Does It Work

Since the  Global health and subsequent economic crisis an emerging trend has dominated the workforce.  That trend is shifting to a work-from-home set-up. Despite the ongoing crisis that causes these changes in the corporate world, it does give advantages to some companies.

Working from home can save money on office space and utilities. Also, it gives more comfort and convenience to the employees since they do not have to get up and deal with rush hours.

However, the company’s cybersecurity security is compromised in a work-from-home setup, hence, prompting each company to secure their communication channels between their business’ computer network and remote work locations by routing through a VPN.

What is a vPN?

A Virtual Private Network (VPN) is a private network that uses a public network (the internet) to be able to connect remote sites or users together. It is the easiest and effective way for companies to protect their internet traffics and hide their identities online from hackers, government, and even your internet service providers since connecting through a VPN will encrypt your internet traffic to a tunnel that nobody can see. Also, when going online, you will have an unusual IP address that won’t be recognized by anyone.

How Does A VPN Work?

A VPN connects your smartphones, tablets, or computers to another computer (called a server) on the internet and allows you to browse the internet using that server’s internet connection.

AT&T Cybersecurity define how a VPN works as

“A VPN connection usually works like this. Data is transmitted from your client machine to a point in your VPN network. The VPN point encrypts your data and sends it through the internet. Another point in your VPN network decrypts your data and sends it to the appropriate internet resource, such as a web server, an email server, or your company's intranet. Then the internet resource sends data back to a point in your VPN network, where it gets encrypted. That encrypted data is sent through the internet to another point in your VPN network, which decrypts the data and sends it back to your client machine.”

In other words, the VPN on your computer encrypts your data traffic and automatically sends it to the VPN’s server through a secure connection. Next, the encrypted data from your computer will be decrypted by the VPN’s server. Then, the VPN server will send the data on the Internet, which is only meant for the user. The traffic will be encrypted again by the VPN’s server and send it back to you. Lastly, the VPN’s software on your device will decrypt the data so you can understand how to use it.

Why Should I Use a VPN?

If you are not yet encouraged by how a VPN works and can protect your security, here are further reasons why you should use it:

You should use a VPN to keep your online activity private and prevent from hacking. Also, a company should use a VPN to connect working from home employees or traveling employees from their central office or home network connection. This will allow you to share local files and browse over the Internet as if you were on the same local area network (LAN).

Benefits of Using a VPN:

1.  A VPN Changes Your Location

A VPN can change your IP (Internet Protocol) address – the numeric address of a computer/device on the Internet that identifies you and your location wherever you are. When you change your IP address through a VPN you can modify your location as if you were in Singapore, Australia, Japan, UK, etc., or to whatever the location the VPN provider has its servers.

2.  Unblock geo-blocked websites

If you are in a country or any locations that restrict some websites like Wikipedia, Google, YouTube, Facebook, Netflix, Twitter, etc., a VPN will allow you to unblock and access to the free internet.

3. Increase your anonymity

As we have said, using a VPN can protect you or the company from hacker attacking.  A VPN helps to protect from rogue Wi-Fi networks, man-in-the-middle attacks, and packet sniffing. If you are always using free public Wi-Fi, it is highly recommended you use a VPN since it is the most untrusted network that you can ever use. The VPN server will stand as your modified proxy for your web activities; hence, it will keep you free from repression, targeting, and discrimination.

4. Protect your privacy

If you do not want to be tracked by anyone else, a VPN will help you hide your identity from applications, websites, and other online services especially if you are browsing from a non-HTTPS website. If you have stronger encryption, it can even hide your activity from your own internet service provider and mobile carrier.
