Recent years have witnessed various cases of leaking confidential information when surfing the internet, which makes netizens panic. An effective tool - VPN - comes into being to prevent personal information leakage when browsing websites. VPN is short for Virtual Private Network. Using a virtual IP address and server protects your network traffic from leaking, stealing, and selling. A great VPN service allows you to browse any site at ease. In this post, I’ll elaborate on how does a VPN work and how to choose a good VPN service.
How VPN Works
VPN is just like a private bridge that connects your device and the site you visit. A VPN tool will provide you with multiple virtual VPN servers and fake IP addresses to hide your actual location. Furthermore, when you connect to the VPN and then visit websites, it can encrypt all the generated network traffic, hiding all of your activities on the network.
Types of VPN
Basically, there are two types of VPN services: Remote Access VPN and Site to Site VPN.
Remote Access VPN
Remote access VPN allows users to access all services and resources of the target website remotely. The connection between the user and the private network is through a remote VPN tool, which is secure and private. Most individual users prefer to use remote access VPN tools. It can bypass the regional restrictions of the Internet and access restricted websites. It also protects Internet security and privacy.
Site-to-Site VPN
Site-to-site VPN is not remote. It connects the network of one office to another by setting up different sites at different locations. It is usually used in some large companies with divisions. This kind of VPN has stronger privacy, and the traffic data is only available on the site network.
Why Use a VPN
It is beneficial to install a VPN tool on your device. Here are the main reasons to use a VPN when surfing the internet.
- Hide personal activities online
One of the primary reasons to have a VPN service is that it can hide all your online activities, such as searching records, visiting platforms, logging in to personal accounts, etc. With it, you can secretly visit any site and do anything. In addition to online activities, it also encrypts personal data, like account information, payment password, company analysis report, etc.
- Bypass geo-restrictions
Another windfall of a VPN service is that it allows you to visit websites with geographical restrictions. Due to geographical factors, some websites are limited to visits by users from other countries or regions. While a VPN can help you change the IP address when visiting sites. In this way, you can access websites and platforms all around the world without any limits.
- Safe to visit public network
Some public networks are free to connect to, like networks in libraries, cafés, schools, banks, etc. But in general, these public networks are not safe. Since everyone can connect to it, your network traffic is very likely to be obtained by others. It is pretty dangerous if you transmit crucial information when connecting to the public. VPN is effective in avoiding that. If you connect to a VPN service when using the public network. It will build a stable tunnel between your device and the web. All information is unavailable to others.
- Hide the actual IP address
It is a big mistake if you deem yourself safe when surfing. Your personal information like name, age, and even address is prone to be exposed to others. Others can locate your actual position by checking the IP address. VPNs can effectively hide your position by cheating others with a virtual IP address. A good VPN service will provide you with several fake IP addresses from different regions. With them, you can synonymously visit sites.
How to Choose a VPN Service
- Multiple servers to select
A good VPN tool is supposed to provide multiple servers from different places with users. Sometimes, it is possible that a server has a not stable network connection. If a VPN tool offers various servers from different countries, users have opportunities to select a suitable and fast one among them.
- Fast connecting speed
Connecting speed is a vital factor when choosing VPN services. It is indeed annoying if the network is stuck and stopped when watching videos, visiting web pages, etc. Therefore, when selecting a VPN tool, it would be best to check the tool’s network speed.
- Visit various websites
As mentioned, VPN can help you cross the geo-restrictions of some websites. If your region is limited by the site you want to visit, first, you need to check whether the VPN tool enables you to bypass the restriction. You can examine whether it offers the server in the region of that website.
- Reasonable price
Completely free VPN tools are not reliable. They are risky to use, for the VPN providers may leak your personal privacy. When choosing a VPN service, you can compare the price and features and install a cost-effective one.
