Which VPN Protocol Leverages Web-Based Applications?

A Virtual Private Network (VPN) creates a secure, encrypted tunnel between two devices through the internet. This allows for private communication between devices on a public or shared network. There are many different types of VPN protocols, each with their own benefits. In this blog post, we will discuss which VPN protocol is best for web-based applications.

Almost every business uses some form of web-based application, whether it’s for email, cloud storage, or collaboration. And as more businesses move to the cloud, the need for secure access to these applications becomes more critical. That’s where a VPN comes in.

What is a VPN Protocol?

A VPN protocol is a set of instructions and standards used to connect devices to each other over a VPN. A VPN protocol defines how data is encrypted and transmitted over a network. There are many different protocols available, each with its own benefits and drawbacks.

The most common VPN protocols are:

-Point-to-Point Tunneling Protocol (PPTP)
-Layer 2 Tunneling Protocol (L2TP)
-IP Security (IPSec)
-Secure Sockets Layer (SSL)
-Transport Layer Security (TLS)

Types of VPN Protocols

A VPN protocol is a set of rules that dictate how data is transmitted over a VPN connection. There are a few different protocols available, and each has its own benefits and drawbacks. Let’s take a look at some of the most popular VPN protocols in use today.

Internet Protocol Security (IPsec)

Internet Protocol Security (IPsec) is a suite of protocols used to secure communication over an IP network. IPsec can be used in conjunction with a number of different network protocols to secure communications. Each protocol has its own benefits and drawbacks, and each is designed to address specific security threats.

The most common protocols used in IPsec are Internet Key Exchange (IKE) and Authentication Header (AH). IKE is responsible for negotiating and managing security associations, while AH provides authentication and integrity for IP packets. Other popular protocols include Encapsulating Security Payload (ESP) and Internet Security Association and Key Management Protocol (ISAKMP).

IPsec is a versatile tool that can be used to secure a variety of different types of communication. It is often used to protect virtual private networks (VPNs), but it can also be used to secure individual TCP/IP connections. IPsec is an important part of many security architectures, and it can be deployed in a variety of different ways.

Layer 2 Tunneling Protocol (L2TP)

Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by internet service providers. It does not provide any encryption or confidentiality by itself. Rather, it relies on an encryption protocol that it passes within the tunnel to provide privacy.

L2TP is often used with the IPsec protocol to secure the communications between two sites. L2TP/IPsec provides data confidentiality, data integrity, and endpoint authentication. In L2TP/IPsec, data integrity is ensured through message digest algorithms and data confidentiality is ensured through encryption algorithms. L2Tp/Ipsec uses IPSec’s Internet Key Exchange (IKE) for key management and negotiation which provides Diffie-Hellman key exchange for generating shared secret keys for use with the ESP transform set. L2Tp/IPsec uses UDP port 500 for both control and data traffic making NAT traversal more difficult but not impossible if properly configured.

L2Tp/IPsec is considered more secure than PPTP but it requires that the server have a public IP address and use a digital certificate from a trusted Certificate Authority.

Secure Socket Tunneling Protocol (SSTP)

SSTP is a proprietary VPN protocol created by Microsoft. It supports both Windows and Linux platforms and works with any type of internet connection, including public Wi-Fi hotspots. When your data is encrypted using SSTP, it’s sent through an SSL/TLS tunnel. This provides a higher level of security than most other VPN protocols and makes it more resistant to blocking by government agencies or internet service providers (ISPs).

One downside of SSTP is that it can only be used with Microsoft products. If you need to use other types of software or devices, you’ll need to choose a different protocol. Another potential disadvantage is that because it’s a proprietary protocol, there’s less transparency around how it works and how secure it really is.


OpenVPN is an open-source software application that implements virtual private network (VPN) techniques for creating secure point-to-point or site-to-site connections in routed or bridged configurations and remote access facilities. It uses a custom security protocol[9] that utilizes SSL/TLS for key exchange. It is capable of traversing network address translators (NATs) and firewalls. It was written by James Yonan and is published under the GNU General Public License (GPL).

OpenVPN allows peers to authenticate each other using pre-shared secret keys, certificates or username/password. When used in a multiclient-server configuration, it allows the server to release an authentication certificate for every client, using signatures and Certificate Authority certificate verification. It uses the OpenSSL encryption library extensively, as well as the SSLv3/TLSv1 protocols.


It is clear that there are benefits to using a VPN protocol that supports web-based applications. By encrypting data and creating a secure tunnel between the user and the VPN server, web-based applications can be used with confidence. In addition, utilizing a protocol that offers fast speeds and low latency is important for a good user experience. For these reasons, it is recommended that users select a VPN protocol that supports web-based applications such as PPTP or L2TP/IPsec.
