In the 21st century, online privacy is becoming more and more critical; it is increasingly important to use VPN software to protect personal privacy. However, we found that different VPN software provides different protocols, so what is the difference between these protocols? Therefore, the theme of this issue is to talk about the differences between different protocols.
security: 2 stars
The PPTP tunnelling protocol is the first VPN protocol, and it has been around for more than 20 years. The protocol relies on encryption, authentication, and peer-to-peer protocol (PPP) negotiation. Essentially, it only needs a username, password, and server address to create a connection. Point-to-Point Tunneling Protocol (PPTP) is a peer-to-peer tunnelling protocol developed by the PPTP Forum consisting of companies such as Microsoft and 3Com. The PPP protocol based on dialling uses encryption algorithms such as PAP or CHAP or uses Microsoft’s peer-to-peer encryption algorithm MPPE. It enables the secure transfer of data from remote clients to dedicated enterprise servers by creating VPNs across TCP/IP-based data networks. Among all protocols, PPTP has the lowest encryption level and does not support Perfect Forward Secrecy. Therefore, it is not recommended to use PPTP for users who are very concerned about security.
Speed: 5 stars
PPTP’s weak encryption brings unparalleled internet speed. In all Internet VPN protocols, PPTP is the fastest. So, if you only care about speed, then PPTP is your first choice.
Security: 3 stars
Layer 2 Tunneling Protocol is a successor to PPTP developed by the IETF based on L2F. Its security is higher than PPTP. Both PPTP and L2TP use PPP protocol to encapsulate data, and then add additional headers for data transmission on the Internet. PPTP can only establish a single tunnel between the two ends. L2TP supports the use of multiple tubes between two endpoints. Users can create different tunnels for different quality of service. L2TP can provide tunnel authentication, while PPTP does not support tunnel authentication. However, when L2TP or PPTP is used together with IPSEC, tunnel authentication can be provided by IPSEC. And it is not necessary to verify that the tunnel uses L2TP on the Layer 2 protocol.
PPTP requires the internet to be an IP network. L2TP only requires the tunnel medium to provide a point-to-point connection to the packet. The IPSec tunnel is the whole process of encapsulation, routing, and decapsulation. The tunnel hides the original data packet inside the new data packet. The new package may have unique addressing and routing information to enable it to be transmitted over the network. When tunnels are used in conjunction with data privacy, hackers who eavesdrop on the system will not be able to obtain raw packet data. When the encapsulated packet arrives at the destination, the encapsulation is removed, and the original packet header is used to route the package to the final destination.
Speed: 4 stars
The speed of L2TP is slightly lower than PPTP.
When using IPSec in tunnel mode, it only encapsulates IP traffic. The IPSec tunnel mode is used primarily for interoperability with other routers, gateways, or end systems that do not support L2TP or PPTP VPN tunnelling over IPSec.

OpenVPN is a new open-source technology that uses the OpenSSL library and the SSLv3/TLSv1 protocol to provide a robust and reliable VPN solution by integrating with other technologies. OpenVPN uses the OpenSSL library to encrypt data and control information. It uses OpesSSL’s encryption and authentication capabilities, meaning it can handle any OpenSSL-supported algorithm. It provides optional packet HMAC functionality to increase the security of the connection. Also, OpenSSL hardware acceleration can improve its performance. OpenVPN is inherently equipped with many security features: it runs in userspace without modifying the kernel and network protocol stack. Therefore, security is very high, and it is a VPN that is currently widely accepted by users.
Speed: 3 stars
OpenVPN is slightly slower than L2TP and PPTP, but its security is very high, and it is one of the widely used VPN protocols. OpenVPN is very secure because it uses a 160-bit SHA1 hash algorithm, AES 256-bit key encryption, and 2048-bit RSA authentication. Of course, the above also indicates that OpenVPN has a significant weakness – delay; the delay between operations is quite substantial for daily activities. However, by using a more powerful computer and the use of SSL certificates, latency can be effectively reduced.
Security: 4 stars
Secure Socket Tunneling Protocol is very similar to OpenVPN, except that it is proprietary software developed and introduced by Microsoft in Windows Vista. Secure Socket Tunneling is now available for Linux, RouterOS, and SEIL; it is also a high degree of agreement on the Windows platform only. And it is equivalent to the possibility of support for Apple devices. There is a snowball in hell.
Speed: 3 stars
Due to the high security, SSTP is slightly slower than the previous three VPN protocols.
Based on the above introduction, we can draw the following conclusions：
It can be seen that almost all VPN protocols have advantages and shortcomings. So what protocol does X-VPN provide? whether you care about speed, security, or the requirements of the applicable platform, X-VPN can meet all your needs. Because we provide a simulated non-VPN protocol. It is able to conceal the IP packets and simulate UDP, TCP, HTTP, HTTPS, FTP and SMTP traffic. What’s more, the simulation will prevent the attacker in finding the characteristics of X-VPN Protocols. When intercepting, at the same time disabling the firewall’s ability to detect X-VPN traffic.
It is one VPN software provides you with a military-grade encryption system and no-delay internet speed, making it the perfect choice for your daily office, home entertainment, and travel unblocking. Generally speaking, we provide 9 Protocols to disguise your internet traffic. Also, X-VPN doesn’t require an account to use the service, masking your actual internet visit request as regular internet data.
