In the past, VPNs were mainly used by corporations to allow secure remote access to their internal services and proprietary data. Now, however, VPNs are available to anyone who wants to protect their connection to the internet, especially when it’s over porous networks like public WiFi, but it’s even useful on a home network.
过去，VPN 主要被企业用于其内部服务和专有数据的远程安全访问。但现在，任何想要保护自己互联网连接的人都可以使用 VPN，尤其是在使用公共 WiFi 等非安全网络时，甚至家庭网络上也有用武之地。
