Securing personal data has always been crucial and that’s how Virtual private networks came into being. Gradually, virtual private networks started to be used by businesses and organizations of different sizes. 

In this article about Virtual Private Networks, we shall know how they work.

How do Virtual Private Networks Work?

A Virtual Private Network (VPN) is a technology that enables secure and private communication over a public network, typically the Internet. It creates a private and encrypted connection, or “tunnel,” between your device and a remote server operated by the VPN service provider. 

Given below is a brief overview of how a Virtual private network works.

  1. Data Encryption: When you connect to a VPN, your computer, smartphone, etc., establishes a secure connection to the VPN server. This connection is encrypted using encryption protocols like OpenVPN, L2TP/IPsec, or IKEv2/IPsec. This encryption ensures that all data sent between your device and the VPN server is unreadable to anyone intercepting it, such as hackers or government surveillance agencies.
  2. IP Address Concealment: When you connect to a VPN server, your device is assigned a new IP address from the VPN server’s pool of addresses. This IP address differs from your actual IP address, which helps conceal your identity and location. When you access websites or online services through the VPN, it seems the requests are coming from the VPN server’s location rather than your own.
  3. Tunnelling: VPNs use tunnelling, a process used to encapsulate and transmit your data securely over the internet. It implies that your data is packaged within encrypted packets and sent through the secure tunnel to the VPN server. This process prevents your data from being intercepted or tampered with during transit.
  4. Access to Remote Resources: Individual users or businesses use VPNs to access resources on a private network in a secure manner. For example, a company might use a VPN to allow remote employees to connect to its internal network as if they were in the office. The employees’ devices establish a VPN connection to the company’s server, granting them access to various resources such as files, printers, and internal websites.
  5. Bypassing Geo-restrictions and Censorship: Businesses might use VPNs to access geographically restricted content. By connecting to a VPN server in a different country, you can make it appear as though you are browsing from that location. It can be utilized to access streaming services, websites, or online content blocked or restricted in your region.
  6. Privacy and Anonymity: While a VPN can enhance your online privacy, it’s important to note that it doesn’t provide complete anonymity. Your VPN service provider can still see your activities, so businesses need to choose a reputable VPN provider with a strict no-logs policy.


Business operations have transformed drastically with the increasing focus on network security. Virtual private networks are beneficial for your business as this technology helps protect your online privacy, secure your internet connection, and enable access to restricted resources.
