Comparing it to an SWE is not a good comparison.

However that sum is low. You need 24/7 security people at watch, both guarding him and the home and then also key family members.

It is possible that he prefers a low attention detail, which reduces cost. But we're still easily talking about a mid two digit number for full-time personal.

It is however likely that different aspects are accounted differently (general company estate security etc.)
