Croissants is Intrusion Detection and Prevention System (IDPS) which requires 3 network interfaces and CPU with AVX2, Zotac ZBox CI549 or MI549 is another good choice for home and/or SOHO users. It's small footprint and Intel Core i5-7300U (Dual Core/4 Hyperthreading) is suitable for home and/or SOHO users for IDPS, like Croissants.
It comes with 2 network interfaces and one Thunderbolt 3 Type-C port which can connect to an adaptor to become another network interface. It also can install up to 32GB DDR4 memory. In my opinion, it can handle up to 1000Mbps bandwidth with low to medium traffic flow even I did not test it at my side at the moment. However, I will purchase one for the test when it is available.
On the other hand, you can install pfsense with suricata plugin on it when Hyperscan is available for FreeBSD or pfsense. pfsense requires 2 network interfaces only.
Finally, the difference between CI549 and MI549 is that CI549 is passive cooling while MI549 is active.
That's all! See you.
