For example, OpenSwan, a popular IPsec implementation for Linux, contains more than 8MB of code in various languages, which at 80 bytes per line would amount to 100,000 lines of code. In general, a larger code base is harder to audit. ![]() IPsec’s code base is significantly larger than WireGuard’s due to IPsec’s inclusion of legacy protocols. ![]() The additional encryption options leave IPsec open to misconfiguration and make it a poorer choice for new VPN configurations. Despite these legacy encryption methods no longer being considered secure, the IPsec user has the option to choose them if, for example, they need to add legacy clients to an existing IPsec VPN. IPsec offers more encryption options than WireGuard, for example, it supports using the RSA algorithm and pre-shared keys for authentication. ![]() IPsec has not been verified in this manner, and due to IPsec’s large code base size a formal verification would be highly complex to execute. WireGuard’s code has been formally verified, and the verification process has been documented in a paper A Cryptographic Analysis of the WireGuard protocol by researchers Benjamin Downling and Kenneth G. WireGuard has a small code base with very little legacy functionality, making it easy for the open source community to audit it for security bugs. Neither the client nor the server can specify an insecure encryption option, and this approach ensures that most (if not all) WireGuard users will rely on recent encryption standards. Whereas IPsec offers many encryption options, many of which can be insecure if incorrectly configured, WireGuard limits the available choices to modern, secure encryption methods. Let’s explore each aspect of comparison in greater detail. Many encryption options present the possibility of using insecure settingsįewer encryption options, focused on modern encryption solutions with more secure defaults Having surveyed dozens of our business VPN customers, it became clear to us that a VPN protocol needs to provide solid encryption, be easy to use and operate, and have clients available for all the relevant devices and operating systems. As providers of business VPN solutions, we focus on comparing the protocols specifically for VPN use within business environments. IPsec and WireGuard are both commonly used VPN protocols. It does not rely upon a dedicated protocol for tunneling. WireGuard offers VPN functionality by encapsulating TCP, UDP, and other IP traffic inside UDP packets with encrypted content. WireGuard is free and open-source, and WireGuard implementations are available for major operating systems. WireGuard is a modern VPN protocol that is simple to use and easy to implement on both new and existing networks. IPsec is supported on many operating systems and device types, including embedded devices and network routers. IPsec is frequently used as the secure communication protocol for business VPNs, most commonly with a tunneling protocol like L2TP. IPsec is a network protocol used for the encryption of IP traffic. Finally, we provide guidance on which might better suit your business VPN use case. We look at both from the standpoints of security, user experience, and platform availability. ![]() In this article, we compare IPsec and WireGuard, two protocols used in VPNs which allow businesses to connect remote networks. VPNs are often the preferred way to allow you and your teammates to access private infrastructure like Kubernetes clusters and file servers, and your ideal solution needs to be secure, easy to use, and easy to administer. If you are tasked with selecting a VPN (Virtual Private Network) solution for your team or company, chances are high that you’ve looked into both IPsec-based and WireGuard-based VPNs as potential options.
