A VPN is the process of creating the safe and secure connection to and from the computer or the network. In other words, VPN is the virtual private network which allows the users to connect with the private network over the Internet for accessing the data privately and securely. Secure VPN protocols creates the encryption which is known as VPN tunnel.
Secure VPN Protocols 2017
All the communication and internet traffic is passed through this secure VPN tunnel which plays a vital role and used to keep the user's data more safe and secure. VPN allows the users to send and receive the data across the public networks because their computing devices are connected to the virtual private networks. Moreover, VPN permits the employees to use the corporate intranet to access the private data when they are locating outside from the office.
Types of Virtual Private Network (VPN)
- Remote Access VPN
- Site to Site VPN
- Remote Access VPN
This kind of VPN permits the users to connect to the private network for accessing its resources and services remotely. The connection between the private network and the user happens via the internet, but the connection is more safe and secure. This Remote access VPN is perfectly suitable for home based users as well as the business users. For instance: A corporate worker is traveling to some other place. At that time, he/she can use the VPN to connect to their company’s private network and access the data and resources remotely.
- Site to Site VPN
The Site to Site VPN is also known as Router to Router VPN which is commonly used by corporate companies. If a company has many branch offices in different geographical locations, they use the site to site VPN which connects the networks of two offices at various places. This site to site VPN type is called as the intranet based VPN when different branches of the same company are connected by using the site to site VPN. Also, this site to site VPN type is called as the extranet based VPN when different companies are connected by using the site to site VPN.
Types of more secure protocols
- Point to Point Tunneling Protocol (PPTP)
PPTP is one of the popular and widely used protocols. Since the period of Windows 95, this PPTP protocol has been in use. Alongside Windows, the Point to Point Tunneling Protocol supports the Mac and Linux operating system. It enables the authorized remote users for connecting to the VPN network with the help of existing internet connection. After that, the users have to log on into the secure VPN protocols by providing appropriate password authentication. The VPN speed is fast in this type of protocol due to lower encryption. PPTP is working well on most of the Wi-Fi hotspots, and it is very stable.
- Layer 2 Tunneling Protocol (L2TP)
The Layer 2 Tunneling Protocol is a type of tunneling protocol and is typical combines with another secure VPN protocols named as IPSec. This combination is performed to create the highly secured VPN connection. The L2TP protocol is used to create the tunnel between the two contact points whereas the IPSec protocol is used to encrypt the data and also to handle secure connection between the tunnel points. This type of protocol supports many operating systems such as Windows, Linux, Mac OS X, Android, and iOS. The user doesn’t worry about their private data as this protocol provides the highest encryption and it encapsulates the data twice. Moreover, the L2TP protocol provides the highest security of the data and is the perfect choice if the open VPN is not supported by your device.
- Internet Protocol Security or IPSec
The Internet Protocol Security is used to provide secure Internet communication across the IP network. The IPSec authenticates the session and encrypts the data packet to protect the internet protocol communication. Typically the IPSec is operating in two modes such as tunneling mode and transport mode for defending data transfer between two different networks. The process of transport mode is to encrypt the message in the data packet whereas the tunneling mode is to encrypt the complete data packet. This protocol requires expensive and time-consuming client installations which are considered as the main disadvantage.
- Secure Sockets Layer (SSL)
SSL is a VPN accessible through HTTP over the web browser. This protocol creates the secure connection between your PC browser and the application server that you are accessing. The SSL protocol uses the internet browser as the client application, so the users need no to install any software. Furthermore, the user access can be restricted to specific applications instead of accessing the entire network. Most of the online shopping websites and service providers are using the Secure Sockets Layer protocol.

Open Vpn: Secure VPN Protocols
Open VPN is the open source VPN which is useful to create the site to site and point to point connections. Open VPN uses the custom security protocol which is based on Sockets Layer protocol and Transport Layer Security. Moreover, it is more stable as well as reliable on Wi-Fi hotspots, non-reliable networks. It is the best performing protocol with high speed even on connections with high latency.
The operating systems such as Windows, Linux, Android, and Mac OS X are supported by the open VPN. It provides the highest encryption for the data, and also it authenticates the data with digital certificates.
Multi-Protocol Label Switching (MPLS)
MPLS protocol is not suitable for individual users to access it remotely. But this protocol is useful for the site to site connectivity. The MPLS network offers high-speed as well it shaping the network traffic flows. This protocol allows the data packets to the switching level (Level 2) rather than forwarding it to the routing level (Level 3).

Secure VPN Protocols
This protocol is designed with very basic encryption when compare to L2TP/IPsec protocol. The major disadvantage of this protocol is that it relies on the point to point protocol to implement the security, but it does not provide the encryption for confidential data.
