The moment, because it's not entirely clear for you.
1. Company resources.
Most companies do not share the internal network's IT resources on the public Internet. To make use of these resources you have to connect to the company's LAN either directly (connect to the network in the company's office) or through the company's VPN, plug in anywhere (at home, in the hotel) to the internet and tie the VPN connection to the company.
2. Unsecured and untrusted networks
You can increase security by establishing communication via VPN from such a network.
3. Territorial restrictions
The vast majority of VOD services (and not only) provide services only to clients connecting to IP assigned to a specific country. if you want to avoid this limitation, you can establish a VPN connection to a server located in a specific country - your client will be seen as if it is connecting to the IP VPN server, therefore the VOD server will "let you" and make limited content available.

Weak (raging, unstable response time) connection is often the enemy of VPN, which will be unbuttoned on the connection.
