When it comes to selecting a VPN, look for one with a large network of servers. If it has a small network, you’ll probably experience server crowding, which will slow you down. . 其次，要选择有客服支持的 VPN。这样即使碰到任何问题，都能获得专人协助。提供可靠 VPN 协议的 VPN 才能带来安全有保障的使用体验。严格的无日志政策也很关键。在理想情况下，最好选择有纯 RAM 服务器的 VPN。这些服务器会定期重启并清楚您的搜索历史。 . CyberGhost VPN covers all of the above and more!

Like any app you run in the background, a VPN uses some battery power. You don’t need to be concerned about a VPN draining your battery to death before the day is done.

The three types of VPNs are commercial, corporate, and self-setup. CyberGhost is a commercial VPN designed to protect your privacy. Corporate VPNs protect businesses’ privacy by letting remote employees work online securely. . Self-setup VPNs are for the passionate few who enjoy doing it themselves. This type of VPN won’t give you access to multiple server locations, nor will it give you the security of a commercial VPN.

VPNs are legal depending on your location. Certain countries have banned VPNs, so you may be blocked from downloading VPN apps. Countries that have banned VPNs compromise the privacy and security of netizens.

VPN是什么意思？它是怎样运作的？

Q: 免费 VPN 怎么样?

Free VPNs are not recommended. They have inferior security, which could lead to data leaks. They also have small server networks, which can slow your connection speed. . Free VPNs have to pay the bills somehow. This means they often bombard you with in-app advertising, which can be super annoying.. For about the price of a quarter pounder with cheese, you can browse the web securely and anonymously with CyberGhost VPN. It’s an affordable VPN packed with premium features.. 零风险安心试用 CyberGhost VPN，享受 45 天退款保证。

Q: 用 VPN 后还会被追踪吗?

You can’t be tracked as long as you’re using a high-quality VPN service. Connecting to a VPN server gives you a different IP address and masks your location. . What’s more, a VPN encrypts all your traffic. If anyone taps into your connection, they won’t be able to make heads or tails of anything. Snoops will only see lines of garbled code which won’t mean a thing to them.. CyberGhost VPN 采用 AES 256 位加密技术。这种顶级的加密算法通常被称为“军事级加密”。

Q: VPN 能兼容哪些设备?

You can run a VPN on anything from a mobile phone to a tablet, laptop, and even a Smart TV. Of course, this all depends on the VPN you choose. . CyberGhost VPN 为以下设备提供专用软件：Windows、macOS、Linux、安卓、iOS、安卓电视以及 Amazon Fire 设备。 . We even offer a Smart DNS feature so you can secure your router or gaming console. . A single CyberGhost subscription lets you connect up to 7 devices at once. Protect all your devices at the same time!

Q: 用 VPN 会拖慢我的网速吗?

It can. But with a good quality VPN, you shouldn’t even notice. Connecting to a server near you will ensure fast connection speeds. Connecting to a server further away will slow your connection slightly, as your traffic has to travel further. Use a high-quality VPN and you won’t feel a difference.. CyberGhost VPN has a huge network of servers, some of which are optimized for specific tasks like streaming and gaming. We use only the best VPN protocols, and we give you the freedom to choose the one you want based on speed and security.

Q: 我需要一直开着 VPN 吗?

Yes, you should. If your VPN is always on, you’re always protected. CyberGhost VPN allows you to select trusted websites the VPN should bypass. Keeping your VPN on all the time ensures your privacy and security when you browse the web.

VPN 通过加密流量来保障您的在线隐私和安全。

_VPN 如何运作？

VPN（虚拟专用网络）是一种可用于加密网络流量的工具。在未连接 VPN 的情况下上网时，您的数据可能会被互联网服务提供商 (ISP) 和您所访问的网站追踪并记录，也容易遭第三方窥探或被网络犯罪分子攻击。

连接 VPN 服务器后，您的流量会通过一个加密隧道进行传输。这能隐藏您的在线活动，防止其被任何人（甚至是 ISP）窥视！VPN 还可以将您的 IP 地址改成为服务器所在位置的 IP 地址。

数据传输未经加密，有被他人拦截和读取的风险

Tor（洋葱路由）

Tor（洋葱路由器）是一种免费、非营利性质的开源网页浏览器。它通过多重中继加密您的数据。这能形成强大的加密，但也可能会显著地降低连接速度。

代理服务器

代理服务器能隐藏您的 IP 地址，从而提升私密性。但它设置起来可能很复杂，且并不对流量进行加密。

Smart DNS

Smart DNS（智能 DNS）通过将您的 DNS（域名服务器）定向到另一个不同位置的服务器来更改您的 IP 地址。它是更改 IP 地址的好方法，但无法提供与 VPN 同等级别的隐私保护。

_常见问题

如何选择 VPN？

选择 VPN 时，首先要看看 VPN 是否拥有庞大的服务器网络。如果网络很小，您可能会遇上服务器拥塞的情况，从而导致网速变慢。

其次，要选择有客服支持的 VPN。这样即使碰到任何问题，都能获得专人协助。提供可靠 VPN 协议的 VPN 才能带来安全有保障的使用体验。严格的无日志政策也很关键。在理想情况下，最好选择有纯 RAM 服务器的 VPN。这些服务器会定期重启并清楚您的搜索历史。

CyberGhost VPN 通通都能做到，还能超越您的期待！

什么是无日志 VPN?

无日志 VPN 的承诺永不记录用户的任何在线活动的 VPN 提供商。这意味着您的流量能百分百保持私密。如果 ISP、警方，甚至是政府要求查看您的搜索历史，这些 VPN 也无法提供任何日志。

CyberGhost VPN 为您加倍用心。我们采用基于 RAM 的服务器。每次服务器重启时，都会清除所有用户数据。

免费 VPN 怎么样?

我们不推荐使用免费 VPN。它们的安全性较弱，可能会导致数据泄漏；同时服务器网络也很小，可能会拖慢您的连接速度。

免费 VPN 也有运营费用。因此它们的应用内经常会有广告轰炸，用起来相当头疼。

只需支付一个大芝士汉堡的费用，您就能用上 CyberGhost VPN，从此安全地匿名地上网。CyberGhost 价格实惠，同时配备了大量优质功能。

零风险安心试用 CyberGhost VPN，享受 45 天退款保证。

用 VPN 后还会被追踪吗?

只要使用高品质的 VPN 服务就不会被追踪。连接 VPN 服务器后您将获得新的 IP 地址，可以隐藏您的位置信息。

此外，VPN 会加密您的所有流量。如果有人偷窥您的网络连接，他们只会徒劳无功，无法读取其中的任何内容。偷窥者只会看到一堆乱码，根本毫无意义。

CyberGhost VPN 采用 AES 256 位加密技术。这种顶级的加密算法通常被称为“军事级加密”。

VPN 能兼容哪些设备?

您可以在手机、平板电脑、笔记本电脑，甚至是智能电视等设备上使用 VPN。当然，这取决于您选择的 VPN 品牌。

CyberGhost VPN 为以下设备提供专用软件：Windows、macOS、Linux、安卓、iOS、安卓电视以及 Amazon Fire 设备。

我们甚至有智能 DNS 功能，帮助您保护路由器或游戏机。

一份 CyberGhost 订阅支持同时连接最多 7 台设备，一次性同时保护您的所有设备！
