出国旅行时，我们会在清单上标注很多事项。在清单中，我们忘记了最重要的东西--VPN。在本文中，我们将向你展示在度假或出国旅行时安装和使用 VPN 的重要性。
安全
One of the primary purposes of a VPN is providing overall protection when surfing the internet. When you are abroad, you may engage in online activities such as shopping, online banking and booking places to stay and others that involve sensitive information. To avoid online security risks and to protect your information, you will need a VPN. A VPN encrypts your internet traffic and uses a secure tunnel for communications. Encryptions ensure your information is safe from prying eyes and in any case if its intercepted, it will not be of any use.
访问受地域限制的内容
Depending on the country you will travel to, one thing is clear, some services available in your country will be unavailable. For instance, US residence will miss Netflix US and UK residents will miss BBC online services as BBC iPlayer isn’t available in other countries. Other social networks might also be blocked. But worry not, with a VPN, everything is taken care of. A VPN has a lot of servers, and let’s say if you want to access restricted US services, you will need to connect to a US server. By doing that, the VPN will assign you a Virtual IP address, and hence the websites and applications will think you are accessing their services from the US. With the encryptions and obfuscation involved, the local ISPs and watchdogs won’t notice anything.
更便宜的机票
航班公司会根据地点和消费者的购买力提供不同的机票价格。 有些航空公司还在某些国家提供巨额折扣。在预订机票之前，请做一些背景调查，找到最便宜的交易地点。然后，清除浏览器的 cookie，连接 VPN，选择位于航班公司提供较低价格的地方的服务器。然后，预订您的价格并享受节省的费用。
除了更便宜的机票，您还可以在其他方面获得更实惠的优惠。例如，在租车时。有些公司还会根据地点不同提供更低的价格；网上购物也是如此。
防范 WIFI 漏洞
On vacation, there are several places where you will be tempted to connect to the free WIFI. From the airport to the hotel room. Sometimes this public WIFI may include malicious people with the intent of stealing your data when you are using the WIFI. They have specialized tools that sniff out, steal and delete private information. When using a VPN, this is not the case as the VPN’s encryptions ensure you are protected. Also, with a new IP address, you will be anonymous and hence achieve some recommended levels of privacy.
底线
From the above, a VPN is an essential entity that should be in your traveling checklist. But be careful when choosing a VPN. Ensure you go for reputable paid ones. The VPN you select should have a lot of servers, high speeds, a higher number of simultaneous connections and also a good privacy policy.
