What Is a VPN and Why Would I Need One

Have you ever thought about how much of your personal life has been transmitted over the Internet? Even if you think that you are not being tracked online, you would probably feel a creeping sensation of dread by now!… If so, then you should also remember that your ISP( Internet Service Provider) can see everything you do on the Internet.

Many ISPs do compile their user’s browsing logs (even anonymous logs) and sell those data to the advertising companies. This is the reason you see advertisements or other content directly without any subscription. This is the primary reason why many people use a VPN. As per the Global Web Index survey, one-half of internet users around the world use VPN.

I hope, there’s quite a definite cause for concern right now. So, let’s see in detail what a VPN is and Why one should need it.

What is a VPN and Why Would I Need One

A VPN offers a secure connection between your computer and a server. It creates a virtual encrypted passage between you and a remote server. It routes all your internet traffic through the virtual tunnel created, so your data will be secure from the prying eyes out there.

To be more precise the VPN servers as an anonymous middleman that does all your browsing, and hides your internet activities from your ISP provider. Which means, your ISP cannot track the sites you visit. Technically, it hides your original IP address.

1.While using public WiFi

A VPN is your best friend when you use a password-protected public Wi-Fi network. If a hacker is on the same Wi-Fi network, it’s very easy for you to track your data. The basic security that your average cafe uses, the password WPA2, does not protect you strongly from others on the network.

Using a VPN will add additional security to your data, allowing you to encrypt all of your communications except the coffee ISP. Then Hackers need to find some easy prey.

2.Geo-Restrictions

Often a VPN will allow you to use paid and accessible streaming services in your home country, but international rights issues may not be available in another. Using a VPN can make you feel like you’re enjoying the same service at home. The use of VPN from non-US countries has seen a sharp increase at events like the Super Bowl and March Madness.

Travelers can also find cheaper rates when using a VPN, as prices can vary from region to region.

3.When you are a distant worker or student

Many employers use a VPN to access corporate services remotely for security reasons. A VPN that connects to your office server can access internal corporate networks and resources when you are away from the office.

4.When you are a political dissident

Many countries do not have the same protections for freedom of the press, speech, and expression, and some governments are taking drastic measures to monitor and take actions they consider a threat to the regime.

For political opponents, it must be said that the use of a VPN (among other confidentiality mechanisms) is essential for the use of the Internet in tyrannical regimes. However, not all are a viable solution, and governments have started to reduce their use.

5.For some Privacy reasons

Even in the comfort of your own home, using a VPN while doing your regular Internetwork is not a terrible idea. Typically, this will prevent you from leaving fingerprints on the web.

Besides these, there are many other reasons you might need to use a VPN. For better clarity in choosing the right VPN, read more reviews on VPNCop.

How does a VPN Work

Once you found a trusted VPN provider, you can download and install their software. Select your preferred security settings and establish a secure connection with the VPN server you want. Once the connection is established, the following process will happen:

  • The VPN software on your computer encrypts your data traffic and sends it to a VPN server over a secure connection.
  • The VPN server will decrypt the encrypted data on your computer.
  • The VPN server sends your data over the Internet and receives a response, which is for you, the user.
  • The traffic is then re-encrypted by the VPN server and redirected to you.
  • The VPN software on your device decrypts the data so that you can understand and use it.

A VPN connection encrypts your data traffic, making it very difficult for hackers and other parties to intercept and view. Secure connectivity provides increased anonymity to the user because Internet traffic is reconnected via an external VPN server. When you browse the web with the IP address of the VPN server, your real IP address is hidden.

Conclusion

Generally, your Internet connection is unique, so your location and even your identity can be revealed by your IP address. Using a different IP address (assigned to a VPN server) allows you to browse the web anonymously, without any of your actions being possible online.

The VPN application runs on the background of your computer, tablet, or smartphone. You can usually use the Internet and not see anything else – except that you can get around the restrictions online.
