VPN的意义
As a preamble, the idea of VPN came when the need arose for people to use computer systems from a far distance and still make it look as if they’re operating from the parent network using the same credentials. This means, you’re trying to create a network in cyberspace, which is not connected physically to one another, but virtually, which means it’s a remote connection.
The main emphasis is ‘’private”. This implies that whatever goes on in the course of this ‘magical’ connection, should be personal, hidden, and strictly private. Therefore, it logically explains itself as a remote or virtual network that is private.
就此而言,作为 VPN 用户,您在一个在线空间中操作,其中的活动只有您自己知道,其他人无法访问。 这类似于您拥有一个只属于您的小型私人互联网。 短期内,虚拟专用网络或 VPN 是一种旨在保护和加密您的连接的安全技术。
VPN 在两个设备之间创建一个安全的私人隧道,就像水流过管道一样,从一端流到另一端,而不被察觉。 这使您可以安全、私密地上网冲浪,享受私人互联网访问。 VPN 在您的设备和 VPN 服务器之间创建加密连接,从而保护您的在线活动并增强您的隐私。
作为初学者,您可能听说过,默认情况下,互联网很容易受到攻击。 你应该也听说过一些人抱怨他们的 Facebook、Instagram 和其他社交媒体账户被黑了。 网络犯罪分子进行此类恶作剧的目的不是庇护他们的受害者,而是利用他们的私人信息,例如银行账户详细信息、信用卡和借记卡详细信息以及其他个人资料,以窃取他们的钱。
它并没有就此结束。 有时,政府可能会决定监视公民的在线活动。 即使是互联网服务提供商 (ISP),也可能会尝试将您的浏览数据出售给广告商。 但是,如果您在计算机或任何其他设备上打开 VPN 应用程序,您的数据将受到保护。 VPN 通过将您的所有在线活动隐藏在隧道中来保护您的数据。 完成此操作后,没有人能够看到您的操作。
This way, your data is secured. Like the water flowing inside a pipe, everybody knows that it is flowing, but nobody can see the content. In the same vein, your ISP and hackers know that you’re connected to the internet, but they cannot see your online activities. A VPN tunnel ensures your privacy by turning your data into encryptions or unreadable scrambles, which become blurring in the eyes of intruders.
虚拟专用网络的工作原理
VPN creates a secure passage between your device and the internet. Every data you key into your device is encrypted and sent through your internet service provider(ISP)to a remote server owned by the VPN company. At this point, they’re decrypted and sent to the internet. Data coming back also adopt the same pattern.
This means that even if they compromise the network you’re connected to, and it happens that somebody is monitoring the data you send and receive, the intruders will only see a flux of scrambled letters and numbers known in cyber security parlance as ciphertext.
说了这些,你可能会问,
’’what’s the major distinction between VPN connection and normal internet connection”?
其中一些区别是:
i. With VPN, every information is encrypted at the point it originated, that is, your computer or device, and is duly decrypted once it gets to the server, which is controlled by the VPN company.
ii. Your real IP address is veiled by the IP address of the VPN server.
iii. Your ISP server is blocked from sighting the websites you visit.
iv. When you use VPN, it may cause the internet speed to slow down due to the time it takes to encrypt and decrypt data.
这也会受到 VPN 服务器速度的影响。 VPN 的速度主要取决于服务器的质量、连接到服务器的人数、配置以及您所在的位置与服务器所在位置之间的距离。
同样,如果速度下降,如果您选择 Symlex VPN 等具有迅雷速度的高性能 VPN,则几乎不会注意到。 您可以使用 VPN 通过切换到可以位于世界任何地方的 VPN 服务器的 IP 地址来更改您的明显位置。
You can use your VPN to change your IP address to the one in the location or country where the content you want to stream is not blocked and you’ll continue to enjoy unrestricted streaming.
您什么时候需要 VPN?
我。 当您想流式传输您所在国家/地区受限制的内容时
There are some video content or TV series that are either restricted or not available to watch in your country probably because of copyright regulations. But this can only affect those who don’t have VPN. With VPN, you can stay in your country and connect to a server in any country of your choice. This will make it appear as if you were in that country physically.
二. 当您想毫无顾忌地使用公共 Wi-Fi 时
很多时候,怀着在机场、公共图书馆、购物中心等地方享受免费冲浪的心态连接到公共 Wi-Fi 时,您会感到兴奋。 这些地方很容易被浏览,因为网络犯罪分子和窥探者总是驻扎在那里,从倒霉和毫无戒心的用户那里窥探和窃取私人信息。 使用 VPN,您在公共 Wi-Fi 上的在线活动受到保护。
三. 当您想在线省钱时
If you’re an online shopper, you will notice that some websites offer different prices to customers from different countries. You can hide the location from which you’re shopping with a VPN, hook on to the server of the country where they offer the price that appeals to you, and it will appear as if you’re shopping from that country.
四. 当您想绕过居住国政府对在线活动的审查时
政府可能会决定取缔某些社交媒体的在线活动,或者通过指示 ISP 提交互联网用户的数据和私人详细信息并仅允许访问政府批准的网站来谴责此类活动。
Symlex VPN 等优质 VPN 的服务器旨在绕过此类规定,让您即使在旅行时也能访问流媒体禁止的内容或网站。 例如,尼日利亚政府最近禁止使用 Twitter。 但是那些在他们的设备上安装了 VPN 的人仍然可以通过上述过程使用 Twitter。
v. 当您希望对您的数据进行严格保密时
当您使用 VPN 时,请放心,没有人可以看到您的在线活动。 这是保证完全隐私的唯一方法。

哪些设备支持使用 VPN?
许多已知的 VPN 都有适用于 Windows、macOS、Linux、Android 和 iOS 的应用程序。 使用 VPN 路由器,您还可以将所有设备连接到 VPN。 VPN 路由器使您能够选择哪些设备连接到 VPN,哪些设备连接到互联网。
VPN 和代理之间的区别
代理是网络技术中的概念之一。 Proxy 能做的一切,VPN 都能做到,但 VPN 能做到的,Proxy 却做不到。 与 VPN 一样,代理可以隐藏您的 IP 地址并跳过地理限制。
IP 是互联网协议的缩写。 它包含关于您的信息,这些信息应该是您的隐私。 但如果将其公开,黑客就可以利用这些信息来利用您。 代理就派上用场了,尤其是当您想观看您所在地区不允许的内容时,例如 YouTube、Netflix 等。
But while VPN can encrypt your online traffic, Proxy cannot, thereby making it accessible to hackers, ISPs, and even authorities. With Proxy, your online traffic is visible to your ISP and those who own the server. Many VPNs maintain a no-logs policy which ensures that there will be no trace or left-over of what you’ve done online. This makes your online business strictly private.
免费和付费 VPN 之间的区别
Basically, you’ll not expect complete satisfaction from anything that is offered for free. Therefore, a paid VPN will inexorably perform better than a free VPN. VPN servers are run with money and are very expensive. So you’ll begin to wonder how free VPNs cover the cost of maintenance and provision of service.
The truth is that many free VPNs exploit their customers to whom they claim to offer ‘’free” services in order to recover costs. This means these customers become the product itself being sold. Free VPNs make money by selling access to your computer and network to third parties.
他们还可以监控您感兴趣的领域并将其出售给第三方。 后者将使用它来向您投放大量广告。 我们建议您避免使用所谓的免费 VPN,而选择付费 VPN。

选择 VPN 服务前要考虑的因素
我。 所在地及管辖范围
您需要找出在您选择的国家/地区控制 VPN 使用的法律。 有些国家/地区强制 VPN 提供商记录有关其用户的信息。
二. 安全
VPN 可以通过多种方式加密您的数据。 这称为 VPN 协议。 有不同类型的 VPN 协议,其中一些协议非常可靠。
这些包括:
OpenVPN、L2TP|IPsec、PPTP、SSTP、IKEv2。
其中,OpenVPN 是最好的,因为它提供了所有高级保护功能,例如速度、设备友好性以及开源。 这意味着用户可以自由验证。
还推荐使用 IKEV2,因为它具有高连接性。
三. 日志记录策略
You should also look for a VPN that insists on a no-log policy. Logging policy is very critical for VPNs as this is the main thrust of privacy. This determines whether the company stores your data and what they do with the information. As we mentioned before, free VPNs don’t really care about your privacy and therefore have no regard for the logging policy.
四. 在面临法律挑战时保护用户的 VPN
一些国家的政府被发现强迫一些 VPN 公司提供一些触犯法律的用户的身份。 真正考验忠诚度的是此类 VPN 公司拒绝披露此类信息的情况。 因此,选择一个可以帮助您克服一切困难的 VPN。
v. 服务器数量和位置
服务器的数量及其位置决定了 VPN 提供的速度和速度质量。 分布在许多地理区域的服务器越多,速度和效率的质量就越高。
六. 终止开关
这是必要的安全设备,可确保在 VPN 连接出现故障时切断对互联网的访问。 Kill switch 将阻止您的 IP 地址被泄露,并防止松散的数据从机器中泄露出去。 好消息是几乎所有 VPN 都有终止开关。
你来吗。 多跳
这个功能虽然不是真正不可或缺的,但仍然有很好的用途。 多跳,也称为双 VPN,是一种通过多个 VPN 服务器多次应用加密的方式建立连接的功能。 这可确保更多隐私,因为它将最大限度地减少 VPN 漏洞。
八。 用户友好和支持
优秀的 VPN 提供商通过 24|7 在线实时聊天、电子邮件和其他客户服务为其客户提供支持。 这些类型的支持使 VPN 的使用变得容易。
九。 良好的付款方式
以隐私为口号的典型 VPN 服务应该能够为用户提供各种支付方式。 出于安全原因,从事记者和举报人等敏感工作的用户应该能够通过比特币等非常规方式进行支付。
结论
At this point, it could be safe to say that the concept of VPN has been demystified. It is believed that an in-depth understanding of what VPN is all about has been achieved. The fact, however is that as long as privacy and security remain the hallmark of internet exploration, the use of VPN is unarguably indispensable. When exploring VPN options, it’s essential to beware of fake VPN apps that may compromise your security. Learn more about how to identify them in our detailed guide.
