In Windows hosts we have for example Qustodio, or in any hosts we use OpenDND FamilyShield.
Web browser in guest system is not filtered (or partially filtered), especially is page is HTTPS (for example porn as literotica and search engines like Google)
It is impossible filter, because https crypt end-to-end content.
Virtualbox could cooperate with parental control ?

"VirtualBox" is (virtual) hardware.

What hardware should VirtualBox be simulating that is involved in parental control?

Hint: the host and guest are separate PCs. Treat them that way. Don't expect PC A to be web filtering on behalf of PC B.
