Why might a company choose to use a VPN?

A company might choose to use a VPN primarily to reduce costs associated with leased lines. VPNs allow organizations to securely connect remote users or branch offices to their corporate network over the internet instead of relying on expensive dedicated leased lines for site-to-site communications. This can lead to significant cost savings since using existing internet infrastructure is generally much more economical than maintaining exclusive lines for secure communication.

In many scenarios, if a business needs to provide remote access to its internal network or provide secure communications between multiple locations, a VPN becomes an ideal solution due to its affordability and scalability. This capability allows the company to ensure secure data transmission at a fraction of the cost of traditional connectivity solutions while still providing sufficient protection against unauthorized access.

Regarding the other options, VPNs do not directly address data storage issues, nor do they enhance the security of physical buildings. Additionally, while monitoring employee productivity might occur in conjunction with VPN use, it is not one of the primary functions or benefits associated with a VPN. Thus, the primary advantage lies in cost reduction rather than these other factors.
