How it's used
The character 衛 is rarely used as a standalone verb in modern spoken Cantonese, appearing mostly in compound words related to health or security. It functions primarily as a formal root in terms like 衛生 or 保衛. When referring to a person who guards a place, Cantonese speakers almost exclusively use the loanword 保安 instead of a term derived from 衛.
Examples
He works as a security guard at the building entrance, responsible for guarding it.

Common mistake
Learners often try to use 衛 as a verb for guarding in daily speech, but it sounds overly literary or archaic. Use 睇住 or 守住 for guarding something in a casual context.
