Knowledge of VPN basics is the key to success

In conditions of growing cyber threat and increasing concerns about online privacy, VPN use is becoming more common. Virtual networks not only allow users to bypass geographic restrictions and access content blocked in their region, but also ensure the privacy of online activities.

Details about each VPN protocol

It is important to understand the basic functioning and capabilities of a VPN. Private networks create an encrypted and secure connection between the user’s gadget and the target resource on the Internet, sending packets of information through an intermediate point - the server.

This approach hides the user's IP address and encrypts his online actions, providing privacy and security. There are several VPN protocols, each of which has its own characteristics, limitations and applications. IPsec, L2TP, PPTP, SSL, TLS, OpenVPN and SSH are the most common of them, more about each:

  • L2TP-based VPN. L2TP (a multi-layer tunneling standard combines the characteristics of PPTP and L2F (layer 2 forwarding). It provides strong encryption algorithms and is compatible with many protocols. This VPN is often used with IPSec to improve security and is often used to protect sensitive information. Although L2TP prioritizes security , its additional load can reduce the speed and efficiency, and even make it unsuitable for some users. Therefore, L2TP-based VPNs are often combined with IPSec, which guarantees that your online activity is hidden from prying eyes.
  • VPN based on PPTP. Point-to-Point Tunneling Protocol (PPTP) is known for being easy to understand and easy to set up. It is actively supported on a variety of platforms and provides fast performance, which puts it in a better position for uninterrupted streaming and gaming sessions. However, the security of PPTP is questionable, so users who value privacy and information security may prefer other protocols. PPTP-based VPN uses TCP port 1723 and GRE protocol for data exchange. When connecting to such a VPN, the device first establishes a secure association with the server, and then a secure communication channel is established between the gadget and the server.
  • SSL-based VPN. So-called web-based VPNs guarantee secure remote access to websites and resources via an Internet browser. They provide a comfortable user experience and do not require installation of additional software. SSL-based VPNs are suitable for users who need to be able to access enterprise network assets from anywhere in the world. However, they may not be suitable for resource-intensive applications. Such VPNs encrypt traffic between the web browser and the server, ensuring confidentiality and data integrity.
  • TLS-based VPN. TLS-based VPNs provide secure network communication using the TLS protocol. They combine strong encryption with high connection speeds, making them suitable for a variety of applications such as VoIP, file sharing and remote access.
  • OpenVPN. A popular open source protocol that offers flexibility, reliability and powerful security features. Due to its openness and adaptability to any traffic encryption method, OpenVPN is the most frequently chosen option for private users and companies.
  • SSH VPN. Built on the SSH protocol, which is often used to provide secure remote access and execution of directives via the command line. They provide secure authentication procedures and a secure channel for information exchange. Such VPNs are popular among technical users and system administrators due to their logic and efficiency in organizing secure network connections. However, they may be less clear to use when compared to the aforementioned VPN protocols.

Final conclusions about VPN protocols

As we can see, there are many VPN protocols in the digital market that suit different needs such as security, speed, ease of use and flexibility. Understanding the advantages and disadvantages of each is important to making informed decisions.

By choosing the right VPN protocol, users can ensure a secure and private online experience and enjoy unlimited access to content and resources.

Private VPN server: priority on maximum protection

A private VPN server uses different standards in its work, depending on the user’s settings and preferences. Typically, OpenVPN or IPSec are used as part of the operation of private VPN servers. These standards create security and guarantee user privacy when transmitting information over the Internet.
