What is a VPN? A Complete Guide In 2023

Have you ever logged into any public Wi-Fi network at any public place like a bank, a library, or a coffee shop? You simply start browsing but did you know there is a high risk to your privacy protection with it?
Well, due to the increase in the consumption of digital platforms for daily activities like important transactions, cybercriminals have taken much advantage. One way to safeguard our data from being captured is by using VPN.
Yes, it is VPN that shields your personal information and prevents it to be illegally accessed by cybercriminals. VPNs encrypt your internet traffic and disguise your online identity. This makes it more difficult for hackers to track your online activities and steal data.
In this article, you will get updated knowledge about what actually VPN is, how it works, what are its benefits, when and where to use it, and most importantly what are the best VPNs to be used in 2023.
What is a VPN?
A VPN, or Virtual Private Network, is a technology that allows users to securely connect to a private network over the internet. This connection is typically made through a VPN client, which is a software application that runs on the user’s device. The VPN client establishes a secure connection to a VPN server, which then acts as a gateway to the private network.
Once connected, all of the user’s internet traffic is routed through the VPN server, which encrypts the data and makes it secure. This means that any information sent or received over the internet, including sensitive data like passwords or personal information, is protected from being intercepted by third parties. Additionally, because the user’s internet traffic is being routed through the VPN server, their IP address is hidden, providing an additional layer of security and privacy.
Why Should I Use a VPN Connection?
There are several reasons why someone might choose to use a VPN connection:
1. Privacy and Security:
One of the main reasons to use a VPN connection is to protect your privacy and security while online. A VPN encrypts your online connection, making it difficult for hackers, government agencies, and other third parties to intercept and view your online activity. This includes sensitive information such as login credentials, credit card numbers, and personal data.
2. Bypassing Geo-Restrictions:
Another reason to use a VPN is to bypass geo-restrictions and access content that may be blocked in your country. Some websites and streaming services are only available in certain regions, and a VPN allows you to connect to a server in another location, making it appear as though you are located in that region.
3. Protecting your Identity:
A VPN also helps to protect your identity by hiding your IP address. This makes it difficult for advertisers, websites, and other organizations to track your online activity and build a profile of your browsing habits.
How Does a VPN Actually Work?
A VPN works by creating a secure, encrypted connection between a user’s device and a VPN server. The process typically involves the following steps:
- The user installs a VPN client, which is a software application that runs on their device.
- The user connects to a VPN server by entering their login credentials and selecting a server location.
- Once connected, the VPN client establishes a secure, encrypted tunnel between the user’s device and the VPN server. This is done using various encryption protocols such as OpenVPN, IKEv2, or L2TP/IPSec.
- All of the user’s traffic is then routed through this encrypted tunnel, which makes it difficult for anyone to intercept and view the data.
- The VPN server acts as a gateway to the internet and the user’s internet traffic is routed through the VPN server before it reaches its final destination. This has the effect of hiding the user’s IP address, making it difficult for anyone to track their online activity.
- When the user wants to disconnect from the VPN, the VPN client closes the encrypted tunnel, and the user’s internet traffic is no longer routed through the VPN server.
It’s important to note that not all VPN providers are created equal, some VPNs are more secure than others and some VPNs keep logs of their user’s activity.
What Does a VPN Hide?
A VPN hides a user’s internet activity by routing it through an encrypted tunnel to a VPN server before it reaches its final destination. This has the effect of hiding the following information:
- IP address: A VPN hides a user’s IP address, making it difficult for websites, advertisers, and other organizations to track their online activity and build a profile of their browsing habits.
- Online activity: A VPN encrypts a user’s internet connection, making it difficult for hackers, government agencies, and other third parties to intercept and view their online activity. This includes sensitive information such as login credentials, credit card numbers, and personal data.
- Physical location: A VPN allows a user to connect to a server in a different location, making it appear as though they are located in that region. This can be used to bypass geo-restrictions and access content that may be blocked in their country.
- ISP tracking: VPN encrypts the user’s internet connection, making it difficult for Internet Service Provider to see the user’s browsing history and traffic data.
Pros and Cons of Using a VPN Connection:
Pros | Cons |
· Privacy and security | · Costly |
· Bypassing geo-restrictions | · Slow internet speed |
· Protecting your identity | · Limited server locations |
· Remote access | · Not all VPNs are trustworthy |
· Public Wi-Fi security | · Complexity |
Types of VPN Connection:
There are several types of VPNs available which include:
1. Remote-Access VPN:
A Remote-Access VPN is a type of VPN that allows users to connect to a remote network over the internet. This is the most common type of VPN and is typically used by remote workers, telecommuters, and other individuals who need to access a company’s network and resources securely.
It uses a combination of software, hardware, and protocols to create a secure connection between a user’s device and the remote network. The user’s device runs VPN client software, which encrypts all data sent and received between the device and the VPN server.
2. Site-to-Site VPN:
This type of VPN, also known as router-to-router VPN connects multiple sites or networks together over the internet. Organizations commonly use this with multiple locations or branch offices that need to connect to a central network.
It uses a combination of hardware and software, typically a VPN router or firewall at each location, to create a secure connection between the sites. The VPN routers or firewalls at each location are configured with the same VPN settings, including the same VPN protocol and encryption settings.
3. Client-to-Site VPN:
A Client-to-Site VPN is a type of Virtual Private Network (VPN) that allows an individual computer (the client) to connect to a private network (the site) over the internet, providing secure and encrypted communication between two. This allows the user to access resources on the private network as if they were physically present on the network.
4. Virtual Private LAN (VPLS)
VPLS is a type of LAN that provides the capability to interconnect multiple LAN segments over a public or shared infrastructure, such as the internet. It enables multiple sites to share a single broadcast domain and enables the communication between sites as if they were all on the same LAN. VPLS is a layer 2 VPN, meaning it operates at the data link layer of the OSI model, providing transparent connectivity between LANs.
5. SSL VPN:
SSL (Secure Sockets Layer) VPN is a type of VPN that provides remote access to a network using an SSL/TLS encryption protocol. It allows users to securely access resources on a private network from anywhere on the internet.
SSL VPNs use certificates and encryption to secure the connection between the client and the VPN server, providing an added layer of security compared to other VPNs.
Does a VPN Make me Anonymous?
A VPN can enhance your online privacy. But it does not make you completely anonymous. When you use a VPN, your internet traffic is encrypted and routed through a VPN server, making it more difficult for others to see what you are doing online. This can help protect your personal information, such as your browsing history and location, from being disclosed to third parties.
However, the VPN provider can still see your internet traffic, and if the VPN provider logs your activity, this information can be sued to identify you. Additionally, your online activity may still be visible to your Internet Service Provider and to any websites or services that you use.
While a VPN can provide a higher level of privacy, it is important to understand that true anonymity is difficult to achieve online and requires using a combination of privacy tools and practices.
Are VPNs legal?
VPNs are generally legal, but the legality of using a VPN can vary by country. In some countries, the use of VPNs is heavily restricted or prohibited, while in others, VPN use is generally allowed.
For example, in countries like China and Russia, the use of VPNs is highly regulated and restricted. In the United States, VPN use is generally allowed, but some states have laws that restrict or prohibit the use of VPNs for certain purposes.
It is important to note that while VPNs can provide a degree of privacy and security, they can also be used for illegal activities. As such, it is important to understand the laws and regulations in your country before using a VPN.
