The purpose of this article is to provide a high-level overview of which VPN protocols leverage web-based applications.

Web-based applications are those that are accessed via a web browser, such as Google Chrome or Microsoft Edge. These applications can be used for a variety of purposes, such as online banking, shopping, or simply browsing the internet.

There are a number of different VPN protocols that can be used to connect to web-based applications, each with its own advantages and disadvantages. The most common protocols are PPTP, L2TP/IPSec, and OpenVPN.

PPTP: PPTP is a fast and easy-to-use protocol that is built into most popular web browsers, such as Google Chrome and Microsoft Edge. PPTP is not as secure as some other protocols, but it is perfect for those who need a quick and easy way to access web-based applications.

L2TP/IPSec: L2TP/IPSec is a more secure protocol than PPTP, but it can be more difficult to set up and configure. L2TP/IPSec is often used by businesses and organizations that need a high level of security for their data and communications.

OpenVPN: OpenVPN is an open source protocol that offers a high level of security and flexibility. OpenVPN can be more difficult to set up than some other protocols, but it is worth the effort if you need a secure and reliable VPN connection.

What is a VPN Protocol?

A VPN Protocol is a technology that enables two computers to communicate over an encrypted connection. This is done by creating a “virtual tunnel” between the two computers, which encrypts all of the data that is sent between them.

There are many different VPN Protocols, but the most common ones are PPTP, L2TP/IPSec, and OpenVPN.

PPTP (Point-to-Point Tunneling Protocol) is the oldest and most well-known VPN Protocol. It is very easy to set up and does not require any software to be installed on the computer. However, PPTP has some security issues and is not as secure as other VPN Protocols.

L2TP/IPSec (Layer 2 Tunneling Protocol/Internet Protocol Security) is a more recent VPN Protocol that combines the features of PPTP and IPSec. L2TP/IPSec is more secure than PPTP but can be more difficult to set up.

OpenVPN is a free and open source VPN Protocol that uses SSL/TLS for encryption. OpenVPN is very secure and is widely considered to be the best VPN Protocol. However, it can be more difficult to set up than PPTP or L2TP/IPSec.

The Three Main Types of VPN Protocols

A VPN, or Virtual Private Network, is a private network that encrypts and tunnels Internet traffic and allows users to remain anonymous and secure when online. There are three main types of VPN protocols: IKEv2, L2TP/IPSec, and OpenVPN.

Internet Protocol Security (IPSec)

Internet Protocol Security (IPSec) is a protocols suite that authenticates and encrypts IP packets. IPSec is widely used in Virtual Private Networks (VPNs) for securing data travelling over untrusted networks, such as the Internet. It can also be used to secure other kinds of communication such as email and file transfer.

IPSec consists of two main components: authentication and encryption. Authentication ensures that only authorized users can access the network, while encryption protects the confidentiality of the data by encoding it so that it cannot be read by anyone who does not have the correct decryption key.

There are two main modes of operation for IPSec: transport mode and tunnel mode. Transport mode encrypts and authenticates each individual IP packet, while tunnel mode encapsulates and encrypts the whole packet. Tunnel mode is typically used in VPNs, while transport mode is more commonly used for host-to-host communications.

IPSec uses a variety of encryption algorithms, including Advanced Encryption Standard (AES), Triple Data Encryption Standard (DES), and Message Digest 5 (MD5). The choice of algorithm depends on the level of security required.

Layer 2 Tunneling Protocol (L2TP)

Layer 2 Tunneling Protocol (L2TP) is often used with Internet Protocol security (IPsec) to create a VPN connection. In most cases, L2TP does not provide any encryption or confidentiality by itself. It relies on an encryption protocol that it passes within the tunnel to provide privacy.

L2TP uses UDP port 1701. UDP is frequently used with VPNs because it has very low overhead and is easier to block than other types of traffic. L2TP is often combined with IPsec, which provides data confidentiality by encrypting all traffic from each end of the tunnel to the other.

Point-to-Point Tunneling Protocol (PPTP)

One of the more popular and common VPN protocols is PPTP, or Point-to-Point Tunneling Protocol. This VPN protocol uses a 128-bit encryption and is known for being one of the first tunneling protocols. It’s still in use today by many VPN providers, but its popularity has faded in recent years.

One reason for this is that it’s based on the PPP, or Point-to-Point Protocol. This is the same protocol thatDial-up internet used to use (and which is now considered to be relatively insecure).

Additionally, while PPTP was at one point considered to be very fast, it’s now considered to be one of the slower protocols (although it’s still faster than some).

The Pros and Cons of each Protocol

There are a few different types of VPN protocols: PPTP, L2TP/IPSec, SSTP, and IKEv2/IPSec. Each protocol has its own benefits and drawbacks. Let’s take a look at each one.

Internet Protocol Security (IPSec)

Internet Protocol Security (IPSec) is a set of protocols used to secure communications over an IP network. It is often used in virtual private networks (VPNs) to protect traffic between two or more private networks. IPSec can also be used to secure individual messages (e.g., email) or traffic flows (e.g., VoIP calls).

IPSec uses a suite of security protocols to provide authentication, confidentiality, and integrity for data packets transmitted over an IP network. These protocols include the Internet Key Exchange (IKE) protocol, the Authentication Header (AH) protocol, and the Encapsulating Security Payload (ESP) protocol.

IKE is responsible for establishing and maintaining IPSec security associations (SAs), which are used to authenticate and encrypt data packets. AH provides authentication for data packets, while ESP provides both authentication and encryption.

IPSec has a number of advantages over other VPN protocols, including better security, easier configuration, and compatibility with a wider range of devices and operating systems. However, IPSec can also be more complex to configure than other protocols and may not be available on all devices.

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 ISPs. 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.

One advantage of L2TP is that it supports two types of authentication: computer-based Extensible Authentication Protocol (EAP) and password-based Challenge-Handshake Authentication Protocol (CHAP). EAP provides stronger authentication than CHAP.

L2TP also has the advantage of being supported by a number of different operating systems, including Windows, Mac OS X, Linux, Solaris, and many versions of UNIX.

A disadvantage of L2TP is that because it uses UDP port 500, it can be blocked by some firewalls. Also, L2TP does not provide any data integrity or data origin authentication.

Point-to-Point Tunneling Protocol (PPTP)

Point-to-Point Tunneling Protocol (PPTP) was one of the first VPN protocols developed. It’s also one of the easiest to set up because it doesn’t require any special software or configuration. All you need is a PPTP-enabled VPN client, which is built into most versions of Windows. However, PPTP is no longer considered secure and should only be used if absolutely necessary.


OpenVPN uses SSL/TLS for key exchange, and IPSec or IKEv2 for encryption/authentication. It can run over UDP or TCP, making it very versatile. In terms of security, OpenVPN is considered to be very robust.

L2TP is a layer 2 tunneling protocol that uses IPsec for encryption and authentication. It is typically used with pre-shared keys (PSKs) or certificates. L2TP is not as secure as OpenVPN, but it is more widely supported by various devices and operating systems.

IKEv2 is a more recent protocol that uses the same encryption/authentication methods as IPSec. IKEv2 is faster and more efficient than IPSec, and it offers additional security features such as Perfect Forward Secrecy (PFS) and MOBIKE.

Which VPN protocol you should use depends on your needs and preferences. If security is your main concern, then OpenVPN is the best option. If compatibility is more important to you, then L2TP or IKEv2 might be a better choice.
