It’s a beautiful Saturday morning, and you’ve settled down on a park bench to sip a coffee and catch up on your favorite news sites, watch a few videos and do some quick online shopping while getting sun and fresh air. Rather than draining your allotted mobile data, you hop onto your city’s public WiFi service. It’s free, and run by the city, so it must be ok, right? The fact is, you can’t be certain the municipal network is secure or even real (see the next point) and set up to protect you from malicious people or entities spying on you while you’re connected. Turning on a VPN can help protect your device from anyone who tries to snoop on the sites you’re visiting or hijack your sensitive login information while you’re kicked back on that park bench any day of the week.
在一个美丽的周六早晨，你坐在公园的长椅上尽情享受阳光和新鲜空气，一边喝着咖啡，一边刷着新闻和视频，同时清清购物车。您未使用移动数据，而是连接到您所在城市的公共 WiFi 服务。它是免费的，且由城市运营，所以它一定没问题，是这样的吗？事实上，你无法确定市政网络是安全的，甚至有可能是假的（见下一点），也无法确定市政网络是否能保障您的上网隐私。打开 VPN 则可避免其他人窥探您在访问的网站或盗取您的敏感登录信息，保护您的设备不被攻击。一身轻松，继续享受这大好时光。
