![]() This may seem to be an outdated technology to this date, especially because of the emergence of newer choices, such as OpenVPN. Point to Point Tunneling Protocol, or what is popularly known as PPTP, is known as the first VPN protocol that has been implemented for Microsoft Windows. Because of this, if you are more concerned with speed that security of the connection, this might not be the perfect choice for you. Aside from the two-step authentication process, higher CPU usage is also required. Much of the disadvantage of the L2TP/IPSec is with regards to its speed. It can be easily configured even manually and on almost all operating systems. When it comes to ease of setup, L2TP/IPSec also offers another great advantage. This is basically because there is a need to first undergo conversion to L2TP before being encrypted, which makes it slower compared to OpenVPN. Nonetheless, while this may offer excellent security architecture, it makes speed suffer. It undergoes data checking twice in order to be ensured of its authentication. When it comes to security, theoretically speaking, there should be nothing to be worried about. The IPSec encryption suite is integrated with L2TP to enable such to be provided with the security that it needs over the network. Layer 2 IP Protocol over IPSec, or what is also known as L2TP/IPSec is another option that can be considered when looking for VPN protocols. Because of this, it is important to pay attention to details to make sure that the configuration will proceed smoothly and that there will be no problems in its use. It can be daunting, especially for those who have not used VPN before. This can also be seen as an additional layer of security.Ĭompared to other VPN protocols that will be mentioned below, especially as against L2TP/IPSec and PPTP, OpenVPN is quite more complicated to set up. As it goes down, the network halts to provide time for reconfiguration, making sure that data will not be lost or corrupted. ![]() Aside from having highest encryption, it also offers data authentication with the use of digital certificates.Īside from security, OpenVPN offers the advantage of having high reliability. It is believed that such has no major vulnerabilities, making it ranked as the most secured amongst the different choices for VPN protocols. It order to deliver unsurpassed strength when it comes to security, it takes advantage of modern technologies, such as SSLv3/TLSv1 protocols.Īmong other things, OpenVPN is preferred by many because of the robust security that it is able to offer its users. While it can be used for various connectivity applications, it is commonly utilized for accessing the internet anonymously and privately. OpenVPNĪn open source software, OpenVPN is one of the most widely used protocols in today’s time. Pay attention to the characteristics of each of these protocols to weigh how one can be different from the other. Below, you can see a comparison of the four choices that you will be generally confronted with. If you are having a hard time deciding on which VPN protocol will prove to be the best, keep on reading. Consider the specific set of features, as well as their pros and cons to come up with an intelligent decision. With this, it is of utmost importance to spend time and spare effort in differentiating one from the other. Nonetheless, not all VPNs will be able to provide the same level of security. A VPN, or virtual private network, will provide you with a secured internet connection that will ensure the protection of the data that you are sending and receiving.
