Explanation / Answer

For the described scenario, setting up a VPN (Virtual Private Network) for the company will be viable choice. Why VPN? The answer to this question lies in the definition of VPN itself given below:

Virtual Private Network (VPN): Virtual Private Network (VPN) can be considered as an extension of a private network encompassing communication links across shared or public networks such as Internet. through VPN, data can be sent between two computers across a shared or public network in the same manner as if it is being sent over a point-to-point private link.

In a VPN to imitate a point-to-point connection, data is encapsulated or wrapped with a header containing routing information, thus allowing the data to traverse the shared or public network to reach the endpoint. To ensure privacy, the data is encrypted for confidentiality. This ensures that even if data is intercepted or hacked over the shared or public network, it is indecipherable without the encryption keys.

Communication on VPN: Whenever two computers (can say server and client) in VPN need to communicate irrespective of their geographic location, a dedicated connection, called VPN connection, is to be established between them. This connection can be thought of as a tunnel through the public network to the private network. All communication through the tunnel is encrypted so that it is secure and private. Due to this, the exact infrastructure of shared or public network used to send the data is irrelevant from user's perspective because logically it apprears that data is being sent over a private dedicated link.

Due to the provision of remote access and routed connections both, company can use VPN connections to trade long-distance dial-up or leased lines for local dial-up or leased lines to an Internet service provider (ISP).

Advantages of VPN: Given below are some of the advantages of VPN:
