What is a VPN? - Virtual Private Network

What Is VPN?

Virtual Private Network (VPN) refers to the ability to establish a secure network connection while using public networks. VPNs encrypt your internet traffic and hide your true identity on the internet. Third parties will have a harder time tracking your online activities and stealing data as a result of this. The encryption is carried out in real-time.

How does a VPN work?

A VPN masks your IP address by allowing the network to route it through a specially configured remote server run by a VPN host. When you use a VPN to access the internet, the VPN server becomes the source of your data. This means that your Internet Service Provider (ISP) and other third parties will be unable to see the websites you visit or the data you transmit and receive over the internet. A VPN acts as a filter, converting all of your data into gibberish. Even if someone managed to obtain your information, it would be meaningless.

What are the benefits of a VPN connection?

A VPN connection hides your online data transmission and protects it from prying eyes. Anyone with network access and a desire to see unencrypted data can do so. Hackers and cybercriminals can't decipher this data if you use a VPN.

Secure encryption: An encryption key is required to read the data. In the event of a brute force attack, a computer would take millions of years to decrypt the code without one. Even on public networks, your online activities are masked with the help of a VPN.

Disguising your whereabouts: VPN servers act as proxies for you on the internet. Your exact location cannot be established since the demographic location data comes from a server in another nation. Some providers, on the other hand, keep track of your actions but do not share them with third parties. This means that any possible record of your user behavior remains permanently hidden.

Access to regional content: It is not always possible to access regional web content from anywhere. Content on services and websites is frequently restricted to various regions of the globe. To establish your location, standard connections use local servers in the nation. This means you won't be able to access content from your home while traveling, and you won't be able to access overseas content from your home. With VPN location spoofing, you may practically "change" your location by switching to a server in another country.

Secure data transfer: You may need to access essential files on your company's network if you operate remotely. This type of data necessitates a secure connection for security reasons. A VPN connection is frequently required to obtain access to the network. To limit the risk of data leakage, VPN services connect to private servers and use encryption methods.

Why should you use a VPN connection?

When you connect to the internet, your ISP normally sets up your connection. It uses your IP address to track you. Your network traffic is routed through the servers of your Internet service provider, who can log and display everything you do online.

Although your Internet service provider may appear to be trustworthy, it may disclose your surfing history with advertising, the police or government, and/or other third parties. Cybercriminals can also target ISPs, compromising your personal and private information if they are hacked.

This is especially critical if you use public Wi-Fi networks frequently. You never know who is watching your online activities or what they might steal from you, such as passwords, personal information, financial information, or even your complete identity.

What should a good VPN do?

You should rely on your VPN to perform one or more tasks. The VPN itself should also be protected against compromise. These are the features you should expect from a comprehensive VPN solution:

  • Encryption of your IP address: A VPN's primary job is to disguise your IP address from your ISP and other third parties. This allows you to communicate and receive information over the internet without fear of it being seen by anybody other than you and your VPN provider.

  • Encryption of protocols: A VPN should also prevent you from leaving traces, such as your browsing history, search history, and cookies. Cookies' encryption is particularly significant since it prevents third parties from having access to sensitive data such as personal information, financial information, and other website content.

  • Kill switch: If your VPN connection is unexpectedly terminated, your secure connection will be terminated as well. A decent VPN can identify this unexpected downtime and shut off pre-selected programs, lowering the risk of data compromise.

  • Two-factor authentication: A strong VPN verifies everyone who tries to log in using several authentication methods. For example, you may be asked to provide a password before receiving a code on your mobile device. Uninvited third parties will have a hard time accessing your encrypted connection as a result of this.


A virtual private network (VPN) creates a secure connection between you and the internet. All of your data traffic is routed over an encrypted virtual tunnel via the VPN. When you access the internet, this masks your IP address, making its location invisible to everyone. External attacks are also protected by a VPN connection. That's because the data in the encrypted tunnel can only be accessed by you – and no one else can because they don't have the key. You can access regionally prohibited content from anywhere in the world using a VPN. Many streaming services are not available in all countries. You can still use the VPN to gain access to them.

Many VPN connections for smartphones are now available, allowing users to keep their mobile data traffic private. The Google Play Store and the iOS App Store are both good places to look for certified providers. However, keep in mind that utilizing a VPN merely anonymizes and protects your internet data traffic. Hacker attacks, Trojans, viruses, and other malware are not protected by a VPN connection. As a result, you should use a third-party anti-virus program.
