What Is VPN?- Virtual Private Network

What Is VPN?

Virtual private network (VPN) is the most common way used to protect your identity and browsing activity from others’ snooping. As VPNs will cover up your internet protocol (IP) address by establishing an encrypted tunnel to router your traffic, everyone can not see inside, including your internet service provider, government, or eavesdroppers.

How does VPN work?

When your devices are connected to VPN, all your data will go through an encrypted tunnel instead of directly connecting with the public internet. Encryption here will make the data unreadable. Especially, when you use the public internet, VPN is crucial to keep your private data from external access. VPN service providers allow you to connect to any of their servers from various locations. Hence your actual IP address and physical location are hidden to keep your browsing activity private. Otherwise, without VPNs, all your search history is easily seen by your internet service provider (ISP), an organization, or someone, and then they can resell these data.

Benefits of VPN 

Disguising your location: as mentioned, you can connect to any VPN server, which acts as your proxy server, from another country, so that nobody can determine your actual location. Most VPN providers comply with their security policies, so they don’t store logs of your data or use them for any purpose. 

Access GEO-blocked services: you may know that some web content only allows access from certain areas of the world. This means that you will not be able to access foreign web services if you do not belong to these regions. With the VPN connection, you can switch your location simply by connecting to a VPN server in another country.

Protect your privacy: VPN will use high-level security such as AES 256-bit encryption. This makes all your communications online look unreadable. So even if hackers are successful to grasp your data, they just see encrypted characters.

Drawback of VPN

VPN could result in a slightly slower internet connection because of the encryption of data during the process you send and receive. This could result in a lag while you browse the internet or download files. More seriously, users who take advantage of VPN to do illegal activities are difficult to detect and prevent from the government, this affects the good aspects of VPN.

What type of VPNs are there ?

There are two main types of VPN, they are remote access VPN and site-to-site VPN.

Remote access VPN

Remote access VPN allows remote users to use a VPN server to access a private network. Also, there is encryption added to protect all data from being sent and received.

The main benefits of remote access VPNs are easy setups and hassle-free use. With the right software, this type of VPN can be easily accessible to newcomers and veterans alike, and is ideal for personal use. However, it may be unsuitable for (and even incompatible with) large-scale business needs.

Site to site VPN

Site-to-site VPN is a private network that allows multiple users in multiple locations to access each other’s resources. 

This type is often applied to companies with many brands in various geographical locations. For example, if you have a company in the US and also have another office in the UK. With the site-to-site VPN, your local networks (LANs) are connected to the wide-area network (WAN). This allows you to access and share securely the information and resources between each other.

Another type is site-to-site VPN for extranets. It is used for two different companies and they are required to connect to work together. 

Companies with a large scale can use site-to-site VPNs to protect sensitive information between a corporate network and remote brands or partner companies. However, they are not easy to implement and don’t offer the flexibility as other types.



GEO-restriction is carried out by website providers to keep access to their website content from several regions of the world. For example, several Asian countries are restricted to access websites such as Netflix, Hulu, and BBC iPlayer. VPN is the best solution used to unlock this restriction so that users can access these sites from anywhere.

IP address

IP address is also Internet Protocol, which is a numerical series used to identify a particular device on the network.


ISP is the Internet Service Provider that provides internet solutions for individuals and organizations. You have to pay for their service to connect with the internet. Therefore, ISP can see and record all your browsing web, and use this data for their purposes.

Kill switch

This feature will protect your IP address and your location in case the internet suddenly breaks off and VPN connections to your device are failed. Because when this happens, your device will immediately show back your actual IP address. And ISP can track it to see all your browsing history. Thanks to the kill switch, your device will immediately shut down the internet connection to safeguard your data.

Split tunneling 

Split tunneling splits a part of your traffic through the encrypted VPN tunnel while some traffic accesses the internet directly. With split tunneling, you can access foreign websites and surf other websites through your local IP address at the same time. 

Data Retention

This is a policy of a company to save logs of user’s activity for a certain period. Without VPN, ISP and other people can easily see your info and resell them for other companies.

DNS leak

It is a security flaw that happens when your actual IP is visible, even although you used VPN to disguise them. It means that ISP and snooper can still track your online activities.

Simultaneous Connections

The number of devices is allowed to connect to a VPN service by the same username.
