I own one, and had it running for 3 years now.  The processor was released in 2016 and it is has several vulnerabilities.  I went through each of their devices and only one is newer (2022 version) but it is overkill for what I need and pricey.  all the others are running old processors, why?  I emailed their support years ago about their chips being vulnerable to such things as spectra/meltdown, etc.. but they haven't did anything to get newer processors, just keep selling same stuff for super high prices.  makes no sense.  Their motto is "take control of your network" but is that for the hacker who can exploit the vulnerabilities of the 2016 processors that are loaded in their product line?  Why not run 12th or 13th generation processors?  Most use them as firewalls but it is a mistake to do that.
