At this time, there is no commercial offering for hardware/ASIC WireGuard implementations. The standard WireGuard implementation cannot reach 10G.
The fastest I am aware of is VPP (open-source) & Intel QAT [1], which while it is achieves impressive numbers for large packets (70Gbps @ 512 / 200Gbps @ 1420 on a $20k+ MSRP server), is still not comparable with commercial IPsec offerings [2][3][4] that can achieve 800Gbps+ on a single gateway (and come with the added benefit of relying on a commercial product with support).

There are also solutions like Arista TunnelSec [1] that can achieve IPsec and VXLANsec at line-rate performance (21.6Tbps per chassis)! This is fairly new and fancy though.

This lack of ASIC is interesting to me. If it existed, that would very much change the game. And, given the simplicity of WG encryption it would be a comparatively small design (lower cost?)
