Types of VPN and types of VPN Protocols

Types of VPN

Different types of VPNs and when to use them (Updated 2018)
An intranet VPN is best for remote offices within the same company, while a remote access VPN makes the most sense for a mobile employee within the company. Deciding which VPN is the best is not easy. You can not post a blank message. IPsec is an abbreviation for Internet Protocol Security. Users conscious of Internet security also use VPN services to enhance their Internet security and privacy.

The Rundown

What are the three types of VPN?

Generally speaking, a VPN or Virtual Private Network is a group of computers or discrete networks networked together over a public network such as the internet. More on what is a VPN and why you need one.

So first off, how do you know if you need a VPN? Well simply put, anyone from a student to a worker, or just someone who wants others to mind their own business with regards to their internet privacy should get a VPN.

There are several types of VPNs. We will discuss each type of VPN in more detail below. Quite a long name for the most commonly used VPN.

This is a useful VPN for both business users and home users. PPTP VPNs are ideal for personal use and business because they do not require the purchase and installation of extra hardware and features typically offered as inexpensive add-on software. The fact that many companies have offices located both nationally and internationally, a Site-to-Site VPN is used to connect the network of the main office location to multiple offices.

This is also known as an Intranet based VPN. In simple terms, Site-to-Site VPNs build a virtual bridge that joins networks at various locations in order to connect them to the internet and maintain a secure and private communication between these networks. However, there is no dedicated line in use allowing the various sites within a company as we just mentioned connect to form a VPN.

Also unlike PPTP, the routing, encryption, and decryption is done by either hardware or software based routers on both ends. The similarities exist in terms of their lack of encryption and that both rely on PPP protocol to do this. They begin to differ with regards to their data confidentially and data integrity. IPsec is an abbreviation for Internet Protocol Security. A tunnel is set up in a remote site allow access to your central site.

An IPsec works to secure the internet protocol communication by verifying each session and individually encrypts the data packets throughout the connection. The two modes are transport mode and tunneling mode. Both modes are to protect data transfer between two different networks. During the transport mode, the message in the data packet is encrypted. In the tunneling mode, the entire data packet is encrypted. A benefit to using an IPsec VPN is that it also can be used in addition to other security protocols to provide a stronger security system.

Although an IPsec is a valuable VPN to have, a great disadvantage to utilizing this protocol is the expensive time consuming client installations that must occur prior to usage. These two work as one protocol.

Both are used to build a VPN connection. This is a VPN connection where the web browser serves as the client and user access is restricted to specific applications only instead of an entire network.

This is because web browsers switch to SSL easily and require practically no action from the user. This is primarily due to the fact that MPLS are the most flexible and adaptable option.

MPLS is a standards based resource that is used to speed up the distribution of network packets over multiple protocols. It also is not easy to make modifications. Although these two types of VPNs are used separately at different sites. However it is possible to use both at the same site. Tried and trusted protocol which sets up a tunnel from the remote site into your central site. IPSec requires expensive, time consuming client installations and this can be considered an important disadvantage.

They offer higher flexibility at both clienbt and server levels and bound to be expensive. Deciding which VPN is the best is not easy. It depends on lot of factors like the number of users, bandwidth, security and cost. Remember — cheaper is not always better. It is better to explore the various options available and see which one suits your needs the best. What is a VPN?
