bodyguard

This term conveys a sense of physical shielding and constant vigilance. It implies a professional relationship where the protector is an extension of the client's personal space, prioritizing the physical safety of a high-profile individual over all other concerns. While often associated with celebrity or political figures, the term can also apply to private security in high-risk environments. It differs from a general security guard in that the focus is on a specific person rather than a building or a general area.
