A VPN also allows you to overcome internet censorship. All your traffic is routed through a remote server, so you can access websites restricted in your country.

How VPN Works?

Let's discuss How VPN Works and the uses of a Virtual private network. VPNs essentially create a data tunnel between your local network and an exit node in another location, which may be thousands of miles away, making it seem like you are in another location. This benefit allows online freedom or the ability to access your favourite apps and websites on the go.

5 Reasons to Use VPN

Here are five cases when you definitely need a VPN. VPN stands for “virtual private network.”. It’s a tool that encrypts your internet traffic and hides your IP address and virtual location.

1. Secure Your Online Data

You need an extra layer of protection when you’re online. Not all websites use HTTPS, a secure communication protocol where S stands for secure. If you’re visiting a website without HTTPS, the data you send or receive can be stolen by cybercriminals or other third parties. 

Unsecure apps also leak your data. Since a VPN encrypts all your internet traffic, you don’t need to worry about insecure websites or apps. That extra layer of encryption makes sure your online data is safe.

2. Access Blocked Websites

If you want to use Youtube in China, VPN is the answer. It changes your IP address and redirects your internet traffic through a remote server, letting you browse under the cover of its IP and access blocked websites. Similarly, 

VPN lets you stay at home — at least virtually — even when you’re travelling. You won’t miss your favourite content when you’re abroad.

3. Unsecured Connections

Public Wi-Fi is inherently insecure. If you spend a lot of time on public hotspots — in hotels, airports, or coffee shops — VPN protection is a must. Without it, a cybercriminal can use many methods to spy on your internet traffic, steal your data, or inject malware into your device. When on public Wi-Fi, VPN must always be on.

4. Avoid Unlawful Government Surveillance

Governments usually have direct or indirect access to internet service providers operating in their jurisdiction. It varies from country to country, but your government may use this access to actively track your online activity. 

Thanks to all kinds of intergovernmental agreements, they may also share this information with other countries. A VPN hides your online activity from all third parties, including your internet service provider and government.

5. File-sharing Services

Peer-to-peer services have many legal and valid uses: distributing open-source software or public domain videos, sharing large amounts of internal information in an organization, or even pushing service updates. 

And yet, internet service providers try to discourage their users from peer-to-peer services by setting bandwidth limits. Use a VPN. With it, your ISP cannot see your traffic and limit your peer-to-peer sharing.

Who Can Use VPN?

Short answer — everyone. VPN Use encryption, so third parties cannot spy on your online activity. Even your internet service provider cannot see what you do online.

  • A freelancer trying not to spill her latte on her laptop.
  • A gamer avoiding bandwidth throttling.
  • A traveller enjoying his favourite content on the move.
  • A VPN is a swiss army knife you can use it depending on your needs.
  • Whether you’re a student overcoming unreasonable Wi-Fi restrictions at your school.
  • Business owners securing sensitive work data.
