role in keeping your data private and secure from third parties. But have you ever wondered how these VPNs work? What are the important concepts behind them to make a secure VPN?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To end the curiosity, the VPN protocols are the root thing of creating a VPN. Without a protocol, a VPN is just nothing. However, there are several types of VPN protocols, and each one of them has distinct features, including compatibility, speed, and encryption.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Let\u2019s uncover each protocol in detail with their strengths and drawbacks to get familiar with each in-depth and to know which is the best protocol for VPN.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"OpenVPN\"><\/span><b>OpenVPN<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">OpenVPN is the most secure VPN protocol in terms of keeping your online activities secure. Most advanced VPN service providers use this because it provides the best encryption. It uses two modes of connection, TCP (Transmission Control Protocol) and UDP (User Datagram Protocol).<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"TCP_Transmission_Control_Protocol\"><\/span><b>TCP (Transmission Control Protocol):<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">It makes sure that all of your data is transferred in the correct order, and if anything is missed in the way of transmission of data, then it sends it again. Since it goes through everything systematically, it makes it a bit slower.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"UDP_User_Datagram_Protocol\"><\/span><b>UDP (User Datagram Protocol):<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">UDP transfers the data carelessly. By sending the data packets quickly, it doesn\u2019t care if any data is missing in the process. No doubt it is faster than TCP, but data transmission is not reliable.<\/span><\/p>\n<h4><span class=\"ez-toc-section\" id=\"Pros\"><\/span><b>Pros<\/b><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">OpenVPN is open source, so any skilled developer can contribute to its source code to make it more secure to use.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">You can comprehensively set the settings according to your needs.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Easily access blocked sites and content over the internet.<\/span><\/li>\n<\/ul>\n<h4><span class=\"ez-toc-section\" id=\"Cons\"><\/span><b>Cons<\/b><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">For learners, it is difficult to set up and involves manual configuration.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Slow speed protocol related to other VPN protocols.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Make your phone battery drain fast.<\/span><\/li>\n<\/ul>\n<h4><span class=\"ez-toc-section\" id=\"Best_Feature\"><\/span><b>Best Feature:<\/b><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">Robust security and steadfast connectivity on public Wi-Fi.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"IKEv2\"><\/span><b>IKEv2<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">IKEv2 is another one of the best VPN protocols; it stands for Internet Key Exchange Version 2.

It depends on your needs to determine which protocols work best for you among many other VPN protocols. You must check VPN protocols in terms of security, speed, and privacy. Additionally, the selection of the best VPN protocol can be made knowing the level of your activity, whether it be for gaming, downloading, or you want to use it for streaming purposes.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"For_Security\"><\/span><b>For Security:<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you do not compromise your security, then OpenVPN and WireGuard are the best VPN protocols for you. As both provide you with the best security. The WireGuard protocol is new, and the use of the ChaCha20 encryption method makes it faster and more famous in the VPN world. However, OpenVPN uses highly encrypted AES-256-bit encryption.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"For_Efficiency\"><\/span><b>For Efficiency:<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">If you are a gamer, then WireGuard is the best protocol for VPN; it will allow you to play games at a faster speed with no lags in between. Furthermore, it has an excellent battery life for cellular phones, so you can play games for a long time with your friends online. <a href=\"https:\/\/iprovpn.com\/\" target=\"_blank\" rel=\"noopener\">iProVPN<\/a> offers this protocol. In addition to it, IKEv2 combined with IPsec provides good security and restores your VPN connection quickly if it disconnects.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"For_Adaptability\"><\/span><b>For Adaptability:<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">OpenVPN, because of its open-source nature, works well on all devices smartly. However, IKEv2 works efficiently on mobile phones, so if you are more of a mobile phone user, then it\u2019s the best protocol for VPN on mobile phones. SSTP is for Windows and can be set on Windows with no trouble.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"For_Configuration\"><\/span><b>For Configuration:<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Since WireGuard is one of the most advanced and new secure protocol protocols, it is easier to configure as compared to other VPN protocols.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_can_I_use_the_VPN_protocol_on_iProVPN\"><\/span><b>How can I use the VPN protocol on iProVPN?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">After you install the app and sign in to it, then from the settings you can find different VPN protocol options. You can select the most secure VPN protocol among them, like WireGuard or OpenVPN, and connect according to your needs. However, if you don\u2019t enable any of the VPN protocols, the automatic VPN protocol will be connected to keep you safe while browsing. <\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><b>Conclusion<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">VPN protocols are the important aspect of a VPN with them there is no existence of VPN. There are several protocols of VPN, all have different levels of security and performance criteria. Depends on your needs on what to choose.
