A Virtual Private Network (VPN) is a secure network connection that allows you to access a private network over the internet. A VPN can be used to securely connect to a public network, such as the internet, and be able to access resources and services as if you are directly connected to the private network.

You may need a VPN if you want to securely access private networks, such as corporate networks, while you are connected to the public network. It can also provide a way to access resources that are only available internally, such as internal company websites or data stores. Additionally, it can be used to circumvent geographical restrictions, such as when travelling or working remotely.

If you think you may need a VPN, consider the following list:

1. Consider your need for a VPN and the types of activities you wish to conduct while connected.
2. Research available VPN providers and read reviews if possible.
3. Evaluate the security features offered by the VPN provider, such as encryption protocols, authentication, and logging policies.
4. Ensure the VPN provider offers service in the country you wish to connect from.
5. Understand the implications of the VPN service on any local laws, if applicable.
