Both do deep packet inspection using netflow protocol and filter using crowd sourced detection rules as well as commercial, process-level filtering on a host operating system to detect network intrusion is unecessarily resource intensive.

ZenArmor does the same as both, but also uses python scripts with a fancy graphical interface.
Do people really run zenarmour, snort or suricate on their desktop?
Feels like a network firewall thing to do DPI for the whole house, instead of a per-machine thing.
Process-level filtering is to avoid exfiltration from environments where "all processes run as the same user, with full access to all other processes"... which, unfortunately, are still most of them.
DPI is nice to stop incoming attacks, and to detect suspicious outgoing traffic, but it's kind of late when the data is already on the wire, and you won't be able to stop all possible kinds of traffic that way.
