What is VPN?

If you have multiple computers, phones and tablets at home, you are using a local area network. These devices are all connected to the same Wi-Fi network and you can even transfer photos or movies from one computer to another without using the internet. Local area networks are private networks by design.

A VPN is a virtual private network. It lets you remotely connect to a private network. For instance, your office might be using a VPN for remote employees. This way, you can establish a connection with your company’s intranet and use your computer as if it were in the office. You’re virtually in the office, using your company’s Wi-Fi network.

Using a VPN is quite simple. Usually, a company or a developer installs a VPN server on a computer at home, in your office or in a data center. Then, users with the right credentials can connect to this server using a VPN client. There are many VPN clients out there on computers, mobile devices and even routers. Windows, Android, iOS and macOS even come with a basic VPN client in your device’s settings.

Why should you use VPN?

Huge numbers of you most likely initially began utilizing a VPN for work, particularly when you're telecommuting. There are a couple of favorable circumstances in utilizing a VPN for an organization. For instance, it gives workers a chance to get to office servers that aren't associated with the web, just like all associated with a similar private system. Back in the prior days cloud-facilitated Office 365 servers or the G Suite, numerous organizations were dealing with their very own email and schedule servers. IT administrations could constrain you to interface with the organization's VPN first to get to your messages and schedule occasions. It's a decent method to ensure delicate data.

However, there are a couple of downsides too. At the point when you utilize a VPN association, all system traffic experiences the VPN, including your web traffic. Your organization's IT administration could uphold exacting perusing rules and keep you from utilizing Twitter. Or on the other hand they could even watch and record your web perusing propensities to locate a decent reason to fire you in the not too distant future (a lot of Reddit, kthxbye).

Be that as it may, office conditions aren't the main use case for a VPN. In the event that you live outside of the U.S., you realize that a VPN can make all the difference when you're attempting to stream something from HBO Now, Netflix's U.S. motion picture library, Hulu or one of the many gushing administrations that confine you from utilizing them abroad.

Numerous organizations give access to a lot of servers around the globe with the goal that you can imagine you're in another nation. As I let you know, when you set up a VPN association, all system traffic experiences a passage and HBO's servers will believe that they're sending information to a client in the U.S. They're sending information to an American IP address for sure (the location of the server), yet everything is then sent through the VPN passage to your gadget on the opposite side of the world.
