If you have been on the internet for a long time then you probably have heard the term VPN or even your friends or teachers could have mentioned it a couple of times. It is one of the most rapidly growing practices in the tech world.

Let’s understand what VPN actually is. VPN actually refers to Virtual Private Network. Its main objective is to initiate a secure connection between the public network and private network. It is actually popular in the business world to protect sensitive data. VPN was actually created to enable branch offices to get access to corporate applications and holdings. To make the security stronger private connection is established with the assist of an encrypted layered tunneling protocol and VPN users use verification methods, which consist of certificates or passwords, to get the access to the VPN. The data or information exchanged between the two positions via the encrypted tunnel cannot be view or translate by other third party or hackers because the system includes various elements to protect both the company’s private network and the outside network through which the remote user connects through.

The initial steps to security in technology would always be a firewall which always sits between the client and host server, which requires the remote user to establish a verified connection with the firewall. Encryption operates by having all data sent from one computer encrypted in such a different way that only the computer it is sending to can decrypt the data.

However, using personal VPN is increasing rapidly. Privacy has increased with a VPN because the user’s original IP address is replaced with one from the VPN provider. Users can get IP of any gateway city the VPN service provides. For example, you might be living in Kathmandu in Nepal but with the help of VPN, you can appear to live in New York, USA or any number of gateway cities.

How does a VPN work?
VPN take care of your privacy by initiating a VPN tunnel across the Internet among your Internet destination and you. The VPN tunnel is actually form by first verifying client like PC, Tablet etc with a VPN server. This VPN server conduct different encryption code to ensure that all the data and your destination where your Internet Service Provider can’t see or monitored. This is done by organizing a encrypted tunnel just like example of giving package to someone by wrapping up and sending it to someone. None of us can see what is inside in the box until it’s opened or cracked by verified one.

This above figure shows the general connection between you and web without VPN. It looks like normal or standard but this connection has various flaws. Your data is open there in the internet any hacker’s or interested groups can peek your data. Generally, Internet is set servers of saving the websites and giving accessing to anyone who wants to see. Those servers communicate with each other to basically let you browse a page. It is great joy to surf but very depressing for privacy.
It’s completely ok if you are surfing various websites for fun and all kinds of research and someone peek in your data. But it’s scary if its online banking, business, and other commercial activities.

Now, this is how your connection look with the same connection but with the addition of VPN. When you operate VPN service, your data gets encrypted and it goes encrypted structure to your ISP then again in a VPN server. VPN act like third party that connects to the web on your behalf. This reduce the tension of privacy and security issues for us at some certain extent.

Benefits of using VPN
The various explanation has been made on the positive side of VPN in recent years. The main argument we get on the positive side of VPN is cost and feasibility. For example, it would be impossible for traveling sales rep to have a private network but if somehow he or she get private network then it would be extremely costly.
In addition to that VPN provide a secure way for distant users to communicate or access information. Also, VPN also hides any user’s browsing activity, which extremely helpful with public network connections. Furthermore, it also enables users to connect to the websites that may be blocked geographically. For instance, various websites are banned in Nepal, so to counterattack that Nepalese people use VPN to get access to those sites. Also, there are various VPN’s that offer built-in ad, tracker blocker or malware. There might be ad-blocking extensions in your browser, it’s difficult to set up everything the same way between browsers and between devices. With the help of ad blocker build right into the VPN, you will see fewer ads and especially fewer targeted ads.
