For a cost effective and viable physical security staffing strategy, which one of the following would you recommend as the best option so that security is not compromised ?

A hybrid security model is widely recommended as the most viable and cost-effective strategy. It combines proprietary (in-house) security with contract security services to balance quality and cost.

• Proprietary security: Provides high-level management, loyalty, and expertise for sensitive areas, ensuring that core security standards are never compromised.
• Contract security: Handles routine, labor-intensive tasks (like patrolling or gate entry), which reduces overhead costs associated with benefits, training, and administration.

While proprietary security (Option A) offers maximum control, it is often prohibitively expensive. Conversely, purely contract security (Option B) or total outsourcing (Option D) can lead to high turnover and a loss of internal oversight. The hybrid model allows an organization to maintain internal control over critical security functions while leveraging the flexibility and lower costs of external providers for general staffing.
