Offloading is really the holy grail of both security and performance because it allows us to embrace industry standard protocols such as SSL/TLS, but by offloading the packet processing to kernel space or hardware, we can push performance to the limits of wire speed.Īt OpenVPN, offloading is key to our performance strategy:
#Wireguard vs openvpn full
SSL/TLS has conventionally been seen as a user space protocol, without a straightforward development path to a high-performance kernel implementation, but this conventional wisdom is being turned on its head by developers who are embracing a concept called "offloading" where you take the "heavy lifting" work of a protocol, such as encryption and forwarding of network packets, and move them to kernel space or specialized hardware that can perform operations at full wire speed. Wireguard needed to reinvent its own network security protocol from scratch rather than leveraging on industry standard protocols such as SSL/TLS, so that it could fit into the more restricted execution environment of the Linux kernel. Wireguard's approach has been to essentially put the entire VPN implementation into kernel space to optimize its performance.

I think what we've seen in general over the last several years is that improvements in network performance at the hardware level has left the software scrambling to catch up. There's nothing about the OpenVPN protocol that in any way limits its potential performance. There seems to be a consensus among many in the industry that OpenVPN is slower than newer protocols like Wireguard.

to create a next-generation VPN service makes the VPN protocol implementation itself a detail rather than the main event. They can handle more concurrent connections and bandwidth per server and lower their overall cost.īy contrast, we are focused on what we see as the next-generation VPN provider model, where last-mile security becomes just a checkbox item in a vast suite of capabilities. In the next-generation model, we give you a secure, virtualized internet in the cloud, and a full suite of enterprise-class tools to manage devices, authentication, routing, network threat detection, load balancing, failover, etc.įor example, consider a company that has millions of IoT devices around the world and needs to securely connect them into a virtualized cloud. These are enterprise-class problems that don't fit into the first-generation VPN provider model, but represent a huge emerging market for VPN providers. We intend to serve this market, but it's not really about whether your protocol is OpenVPN or WireGuard. The R&D, development, integration, operations, etc. And Wireguard gives them a way to optimize their operations within the scope of the first-generation business model. Most VPN providers are what we could call first-generation providers they are focusing on last-mile security.

What is your take on what’s driving that? Many VPN providers are switching to using Wireguard. We've essentially taken the capabilities of enterprise-class VPN solutions while reducing the cost and complexity of deployment down to the level of a consumer VPN service. This is our next generation VPN-as-a-service technology that's actually available today via our OpenVPN Cloud solution.
