What is a VPN Protocol?
A protocol is what is used to create a secured pathway between your computer and the VPN server. Protocols are used to insure that the connection remains secure and stable while you use the VPN.
The primary responsibilities of the VPN protocol are authentication and encryption. Authentication is what verifies that your Mac or PC is communicating with a trusted and secure VPN server, and encryption is what makes your connection unreadable to outside sources. Intego Privacy Protection VPN offers two different protocol options, OpenVPN and WireGuard. Each have their own benefits, depending on your usage and connection preferences.
What is OpenVPN?
OpenVPN is an open sourced (the software and its code are openly available to anyone for free) VPN protocol and code that was developed and released in 2001. It is one of the most widely used protocols, due to its reliability and flexible usage.
What is WireGuard?
WireGuard is also an open sourced VPN protocol that was released much more recently, in 2019. It offers a much less lengthy code structure (roughly 4,000 lines of code vs OpenVPN's 100s of thousands). It also boasts faster connection time and over all connection speed.
Which Protocol Should I Use?
Both protocol options offer their own benefits. For example, WireGuard typically allows for faster connection and networking speed than OpenVPN, but you may experience more drops in connection while using WireGuard in comparison to OpenVPN. They are both completely reliable when it comes to securing your network traffic information.
