Edera developer here. gVisor is restrictive, but its at a cost of performance. Personally, I'd say Edera Protect is one level deeper. We create Edera Protect Zones to provide isolation, so we create a Zone that is isolated from the OS and hardware of the machine running the container. So we don't proxy or filter syscalls, as the isolation is a layer deeper. We are also focused on ensuring that Edera Protect is as performant (if not better) as running a container today with containerd.

Finally, if you wanted to, you could run gVisor within Edera Protect, but we feel that Edera Protect would already provide the security benefits that gVisor offer.

Thanks, but what is a “Protect Zone” at a technical level? Why does it provider stronger isolation than syscall filtering?

How would you say it compares to Firecracker?
