What Are the Main Types Of VPN

Virtual private networks, commonly known as VPNs, provide a secure and private tunnel on a public connection. With the use of a VPN, data can be transferred safely and securely without any miss-authorization. Here is a complete guide on the Types Of VPN.

Benefits Of Using A VPN:

Let’s look at a few benefits of using a VPN when browsing the internet:

  • Secure Connection: A VPN encrypts your connection to ensure that data cannot be accessed by any third party.
  • Public Connection Is Made Into A Private One: While using any public internet connection, the IP address used by the user is shared with everyone. A VPN enables a direct connection between the two networks without revealing the location of any user.
  • Cost-Effective Security: Most of the security protocols offered on the internet are quite expensive and are out of reach of small organizations and individuals. Only large organizations have access to those. A VPN is not only cost-effective but also provides high security to the user.
  • Accessing Any Geo-Locked Content: There is much content offered on the Internet which is not available for people of all locations due to licensing and other agreements. Israel can be one example that has certain geo locations in place. Remote workers can benefit greatly from it: Recently the COVID wave and the work-from-home policy implemented it made it difficult for users to secure their privacy in remote working conditions. VPN was of great use here as it provides safe and secure access to your data 

What Are The 4 Main Types Of VPN Based On Their Architecture?

A VPN uses a private tunnel to establish a secure connection between two networks. This private tunnel is made in different architectures according to situations. There are 4 main types of VPNs architecture:

  1. Remote Access VPNs: A remote access VPN lets you connect to a private network like that of your organization. Data is kept private and secure using encryption. Remote Access VPN is typically used when working from home or traveling and there is a need to connect with the office network.
  2. Personal VPN Services: This type of VPN protocol makes your connection with the VPN server and hides your identity and location. It is generally useful if you want to watch movies when you are using public internet etc. which are a few of the VPN examples. For example, a VPN to Israel can be used to surpass that. Our most recommended one is VeePN which offers a free trial to its users. These types of content may be needed by you and of use to you in a certain way. In such cases, VPN can be of use as it hides your location and sends it through different VPN servers to ensure you are able to access any content from anywhere across the world.
  3. Mobile VPNs: A mobile VPN is one where the connection does not end in case the Wi-Fi is switched off or even when the device is shut off for some time. It is particularly useful if the user does not have a stable internet connection as the remote connection disconnects every time the network goes, even for a while.
  4. Site-to-site VPNs: A site-to-site VPNs also known as network-based VPNs, are used to join two networks on a different site. A perfect example would be a company having two offices in two separate locations, a site-to-site VPN can be used to combine these both networks into a single one by establishing a secure connection between them.

What Are The Difference Types Of VPN Protocols?

A protocol like in any other matter is a set of rules which need to be followed by both parties to establish a connection. Similarly, there are many protocols that need to be followed by both networks if they plan on establishing a VPN connection. Some of the most commonly used protocols are:

  1. Open VPN: OpenVPN is one of the most widely used VPNs in an open source i.e. it is supported by the open community of contributors over the world. There are two types of Openvpn. OpenVPN community edition is the first one that is free for its users and also gives the community access to assistance. The other type is an Open VPN access server which is not free and charges a nominal subscription fee. This VPN can not only be customized but is also available at reasonable prices. The disadvantage, however, is that it is difficult to set up on many operating systems. When one questions regarding what is the most common type of VPN I think this may be your answer.
  2. IPSec VPN: Internet Protocol Security or IPSec is the most commonly used VPN protocol in today’s digital world, especially by businesses. It is basically a series of protocols that ensure complete security and encryption to avoid any misuse or mis authorization of data. It is perfect for us in a corporate environment. However, its configuration is often found to be complicated by many users.
  3. L2TP VPN: It is a Layer 2 Tunneling Protocol (L2TP) that is used for securing a VPN connection. It is an old-school connection that is sometimes considered obsolete but is still used by many for interoperability purposes.
  4. SSL VPN: It is a Secure Sockets Layer (SSL) protocol that provides security at many ends. It is widely used in cases of remote access, however, is considered obsolete by many organizations due to its weak cipher.
  5. PPTP VPN: Point-to-Point Tunneling Protocol was developed by the infamous company Microsoft. It is also an old VPN protocol that is known to have many setbacks as its encryption is not very strong but is still commonly used due to its simple and easy features. It can also come across many windows firewalls that other VPNs can’t.
  6. SSTP VPN: Secure Socket Tunneling Protocol VPN (SSTP VPN) is one of the commonly used VPNs developed by Microsoft. It, however, only uses remote access architecture and does not support other architectures like site-to-site.

Final Thoughts

VPN provides a safe and secure private tunnel to its users in order to make connections to the Internet. There are many different types of VPNs and their architectures offered by VPN services which can be used in different scenarios. There are also many protocols that need to match between the two networks in order to establish a secure VPN connection.
