What are the main use cases for VPNs and why might someone need one?

There are four primary use cases for VPNs that address different online needs. The first two involve circumventing restrictions: bypassing throttling, blocking, or bans imposed by schools or governments on websites, and accessing region-locked content like different countries' Netflix libraries. The remaining use cases focus on security and privacy. VPNs can obscure your IP address to enhance online privacy and anonymity. They also enable secure access to remote networks, allowing you to safely connect to your home or business network from external locations. Each use case serves specific scenarios, from overcoming geographical limitations and institutional restrictions to protecting personal data and maintaining secure remote connections for work or personal purposes.
