A virtual private network (VPN) is a secure connection that enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network, while benefiting from the functionality, security and management policies of the private network.
A VPN is created by establishing a virtual point-to-point connection through the use of dedicated connections, virtual tunneling protocols, or traffic encryption. A VPN available from a service provider, also known as a commercial VPN, enables a remote user to securely connect to a remote network over a public Internet connection. A VPN connection on a local area network (LAN) enables a user to send data across a shared or public network securely.
Many businesses and organizations use VPNs to allow employees to work remotely while still securely accessing the company’s network. VPNs are also commonly used by individuals to protect their privacy and security when using public Wi-Fi networks.
How does a VPN work?
A VPN works by creating a secure tunnel between your device and a VPN server. This tunnel encrypts all of your traffic, making it unreadable to anyone who might be eavesdropping on the network.
When you connect to a VPN, your device sends a request to the VPN server. The VPN server then authenticates you and creates a secure tunnel between your device and the server. Once the tunnel is created, all of your traffic is encrypted and sent through the tunnel to the VPN server. The VPN server then decrypts your traffic and sends it to its intended destination.
Benefits of using a VPN
There are many benefits to using a VPN, including:
- Security: A VPN encrypts your traffic, making it unreadable to anyone who might be eavesdropping on the network. This includes your ISP, hackers, and government agencies.
- Privacy: A VPN hides your IP address, making it difficult for websites and other online services to track your activity. This can help you protect your privacy and avoid being targeted by ads.
- Access to blocked content: A VPN can be used to access content that is blocked in your region. For example, you can use a VPN to watch Netflix US if you are located in the UK.
- Increased speed: A VPN can sometimes increase your internet speed. This is because the VPN server is often located closer to the website or service you are trying to access than your ISP’s servers.

- Security: Make sure the VPN you choose uses strong encryption and has a good reputation for security.
