If you are looking for a VPN protocol that will allow you to securely connect to web-based applications, then you may want to consider using IPsec. IPsec is a powerful and widely used protocol that can provide both security and performance for your online activities.

What is a VPN Protocol?

VPN is short for Virtual Private Network. A VPN protocol is a set of rules that govern how data is exchanged between computers on a VPN network. There are several different VPN protocols, each with its own advantages and disadvantages. In this article, we will focus on which VPN protocol is best for web-based applications.

Internet Protocol Security (IPsec)

Internet Protocol Security (IPsec) is a suite of protocols developed to secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a data stream. IPsec also includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session.

IPsec is an end-to-end security scheme operating in the Internet Layer of network protocols. It can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). In each case, the data flows are secured by encrypting and/or authenticating each packet in the data stream.

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.

L2TP uses UDP port 1701. L2TP packets consist of an L2TP header and a data-link layer PDU. The L2TP header is 4 octets long and contains 16 bits of each of the following:
-Control message bit field
-Session ID
-Naming information

Following the L2TP header is the data-link layer PDU, which can be either an L2TP message or an L2CP message.

Point-to-Point Tunneling Protocol (PPTP)

PPTP was one of the first VPN protocols developed and is still one of the most common. It’s known for its relatively fast speeds, but it’s also relatively weak in terms of security. That said, it’s still a valid option, particularly if you’re using a VPN for simple tasks like streaming video or bypassing regional restrictions.

Secure Sockets Layer (SSL)

Secure Sockets Layer (SSL) is a standard security protocol for establishing encrypted links between a web server and a browser in an online communication. The usage of SSL technology ensures that all data exchanged between the web server and browser remains secure and private. SSL is an integral part of securing data on the Internet and is used by millions of websites in protecting their online transactions with their customers.

How Do VPN Protocols Work?

A VPN, or Virtual Private Network, is a technology that creates a secure, encrypted connection over a less secure network. VPNs can be used to access region-restricted websites, shield your browsing activity from prying eyes on public Wi-Fi, and more. But how do they actually work? Let’s take a look.

Internet Protocol Security (IPsec)

IPsec is a technique for securing data that is sent over an IP network. It is most often used in VPNs, or Virtual Private Networks. When data is encrypted with IPsec, it can only be decrypted by someone who has the appropriate key. This makes it very difficult for someone to intercept and read the data.

IPsec uses two types of cryptography: symmetric-key cryptography and public-key cryptography. The most common symmetric algorithm used with IPsec is the Advanced Encryption Standard (AES). The most common public-key algorithm used with IPsec is RSA.

IPsec can be used in two different modes: transport mode and tunnel mode. Transport mode encrypts the data within the IP packet, but does not encrypt the header information. Tunnel mode encrypts both the data and the header information. Tunnel mode is more often used in VPNs because it provides a higher level of security.

There are two main protocols that are used with IPsec: Internet Key Exchange (IKE) and Encapsulating Security Payload (ESP). IKE is responsible for setting up the security associations between two devices, and ESP handles the actual encryption and decryption of the data.

Layer 2 Tunneling Protocol (L2TP)

L2TP uses UDP port 1701 and can be run over any IP-based network, such as the Internet or an intranet. L2TP requires that the underlying network supports multicast traffic—or in other words, that packets can be sent to multiple destinations simultaneously.

L2TP is usually used with another VPN protocol, such as IPSec, for added security. When used together, L2TP and IPSec provide a high level of security for remote access to corporate resources. As with IPSec, L2TP uses encryption to protect data as it traverses the network.

L2TP/IPSec is more secure than PPTP but less secure than OpenVPN. It is supported by most major VPN providers.

Point-to-Point Tunneling Protocol (PPTP)

PPTP is one of the oldest and most trusted VPN protocols. It’s been around since the days of Windows 95, and while it does have some security flaws, it’s still a good option if you need a fast and simple VPN.

How PPTP works is pretty simple. You install a PPTP client on your computer or mobile device, and then connect to a PPTP server. The server essentially acts as a middleman, forwarding traffic between you and the internet. Because the traffic is encrypted, your ISP can’t see what you’re doing online. And because the server knows your IP address, websites will see the IP address of the server instead of your own.

One thing to keep in mind is that PPTP isn’t as secure as some other protocols (like OpenVPN or L2TP/IPSec). That’s because PPTP uses an outdated encryption method called MS-CHAPv2. MS-CHAPv2 has been cracked, which means that if someone really wanted to snoop on your traffic, they could probably do it.

That said, unless you’re engaging in activities that are likely to get you in trouble (like downloading copyrighted material), PPTP is probably good enough for most people.

Secure Sockets Layer (SSL)

SSL is the most common type of VPN protocol used today. It is a web-based protocol that can be used with a wide variety of applications, including email, file sharing, and voice over IP (VoIP). SSL uses encryption to protect data in transit, and it can be configured to run over either the Public Internet or a private network. SSL is typically used with transport layer security (TLS) to provide an additional layer of security.


No single VPN protocol can be considered the best for all web-based applications. The best VPN protocol for a particular application will depend on a number of factors, including the specific requirements of the application, the capabilities of the VPN server, and the preferences of the user. In general, however, it is advisable to use a protocol that offers strong security and privacy protection, such as OpenVPN or IKEv2.
