If you’re looking for a VPN protocol that offers both security and speed, you may want to consider using PPTP with the Secure Sockets Layer (SSL) protocol. PPTP is a great choice for encrypting traffic, and SSL provides an extra layer of security.

There are many different types of VPN protocols, each with its own advantages and disadvantages. In this article, we’ll compare the most popular protocols: PPTP, L2TP/IPSec, SSTP, and IKEv2. We’ll also briefly touch on OpenVPN, which is a more versatile but less common protocol.
Secure Sockets Layer (SSL)
Secure Sockets Layer (SSL) is a protocol that uses TCP to provide a secure connection between two computers. SSL uses encryption to prevent eavesdropping and message forgery, and includes authentication to prevent impersonation. PPTP traffic can be encapsulated using SSL, which adds an extra layer of security.
Point-to-Point Tunneling Protocol (PPTP)
Point-to-Point Tunneling Protocol (PPTP) is a VPN protocol that encapsulates PPTP traffic using the Secure Sockets Layer ().
Encapsulation is the process of binding together data and code into a single unit. This encapsulation process allows the code and data to be protected from outside forces. The most common type of encapsulation is done using the Secure Sockets Layer (SSL). SSL is a protocol that is used to encapsulate PPTP traffic.
Internet Protocol Security (IPsec)
Internet Protocol Security (IPsec) is a secure network protocol suite that authenticates and encrypts the packets of data sent over an internet protocol network. It is often used in virtual private networks (VPNs) to protect the data traveling between a VPN client and server.
When used in conjunction with the Point-to-Point Protocol (PPP), IPsec can provide encryption for PPTP traffic. This is especially important when PPTP is used over public networks, such as the Internet, where the data may be intercepted by third parties.
IPsec uses the Secure Sockets Layer (SSL) to encapsulate PPTP traffic. SSL is a secure communications protocol that is often used to protect web traffic. By encapsulating PPTP traffic in SSL, IPsec ensures that the data is encrypted and authenticated before it is sent over the network.
IPsec is a key component of many VPNs, and it is important to understand how it works in order to choose the right VPN for your needs. If you are looking for a VPN that will encrypt your PPTP traffic, be sure to choose one that offers IPsec encryption.
Layer 2 Tunneling Protocol (L2TP)
L2TP is a tunneling protocol that encapsulates PPP traffic over an IP network. L2TP uses Point-to-Point Protocol (PPP) for data link layer services and can be used with most versions of the Microsoft Windows operating system, as well as with the popular Linux OS. L2TP provides support for multiprotocol traffic, as well as for multilink and load balancing. L2TP uses UDP port 1701, making it incompatible with NAT unless used in conjunction with IPSec.
There are many VPN protocols that can be used to encapsulate PPTP traffic using the Secure Sockets Layer (SSL). Some of the most popular protocols include: OpenVPN, L2TP/IPsec, and SSTP.
SSL vs. PPTP
When it comes to choosing a VPN protocol, there are a few different options to choose from. Two of the most popular protocols are SSL and PPTP. So, which one is better?
SSL is a more recent protocol that uses the Secure Sockets Layer () to encapsulate PPTP traffic. It is more secure than PPTP, but it is also more expensive to set up.
PPTP is an older protocol that uses Point-to-Point Tunnelling Protocol () to encapsulate traffic. It is less secure than SSL, but it is cheaper to set up.
IPsec vs. L2TP
Layer 2 Tunneling Protocol (L2TP) is a protocol used to send traffic through an IPsec tunnel. L2TP uses UDP port 1701 and can be configured to use either pre-shared keys or certificates for authentication. L2TP/IPsec is often used in conjunction with other protocols such as PPTP or SSTP.
Internet Protocol Security (IPsec) is a protocol suite that authenticates and encrypts traffic at the IP layer. IPsec uses AH and ESP headers to provide security for traffic at the network layer. AH authenticates the IP packet header and ESP authenticates and encrypts the data payload. IPsec can be used with either Transport Mode or Tunnel Mode. In Transport Mode, only the data payload is encrypted. In Tunnel Mode, the entire data packet is encrypted and authenticated
