Beginner Guide to Virtual Private Network (VPN)

Virtual Private Network (VPN) is able to route your internet connection to another server that is owned by the provider. It does not guarantee to completely block third parties from tracking your web activities. However, it can significantly reduce the amount of tracking carried out on your web activities.

How VPN Works?

VPNs can generate another IP address to disguise your original IP address. The IP address is a string of numbers that is assigned to your device when you are connected to the internet. Disguising the IP address can prevent people from detecting your location. A secure tunnel is created when your device is connected to the VPN. The tunnel will encrypt your data to the requested website. If someone tries to intercept the data, the data will become unreadable. Get more details at: How Does a VPN Work?

Why Use a VPN?

Many websites did not have any security measures when transferring customer information. For example, it is not safe to buy a product with your credit card when you are using the cafe internet. An anonymous person that is also accessing the cafe internet can learn about the sensitive information you enter on the website. But if you use a VPN, this information will be cloaked and hidden from the hacker. Your device will be seen on the server of the VPN network, and your IP address will be the IP address of the VPN server. This allows you to surf the internet safely, knowing that your personal information is protected.

Types of VPN

Client to Provider

Client to provider VPN is the type of VPN that people buy from VPN providers to hide their IP address when surfing the web. With this form of VPN, you must first install a VPN client on your computer. Once installed, you must connect it to the remote VPN server of the VPN provider. Client to provider VPN is often used by people who want to surf in hotspot areas like airport and hotel. People also use the client to provide a VPN for privacy concerns when surfing the web.

Surfing via a VPN can protect you from being tracked by website owners who are logging the user information to use for their business. There is only a low likelihood that the VPN provider will use the information it logs on the user traffic for its selling point. Client to provider VPN is also suitable for people who are facing with government restriction problems on the use of the internet.

In some countries, certain websites are banned from being accessed by the residents. Or, if you are using the school internet, and the website you want to visit is being blocked, you can use the VPN service to unblock the website so that you can view the content.

Remote Client VPN

Remote client VPN is used by a remote user to access a private local network when on a public network. With a remote client, you need to install a VPN client. Remote client VPN is used by a remote worker to connect to a secure network for accessing data and applications they need for performing their job duties. Campus students also frequently use a remote client to connect to a network that provides access to the data they need for their studies.

Site to Site VPN

Site to site VPN is another common form of VPN that involves a connection in between two public networks. Site to site VPN prevents the need of having to spend money to purchase a VPN service. There is no need to set up a client. Remote connection takes place between two VPN servers. User has to connect to a local network that is connected to the gateway in order to use this VPN service.

Should You Choose a Free or Paid VPN?

It is worthwhile to pay for a VPN if you want a secure and fast connection. Free VPN usually only provides the PPTP protocol which cannot effectively hide your identity. You can frequently get tracked by third parties when you are using free VPN to surf the web. Paid VPN has more choices on the server locations and they also supply more bandwidth.

Paid VPN will use a more secure protocol such as SSTP and IKEv2. Secure Socket Tunneling Protocol (SSTP) is a secure protocol invented by Microsoft. With SSTP, the data can only be decoded by the two parties that are using it. Internet Key Exchange version 2 (IKEv2) is a more secure form of protocol created by both Microsoft and Cisco. The protocol is often used on mobile devices.
