Proprietary vs. Contract Security

Whether security officers are directly employed by the property/company (proprietary) or supplied by a licensed outside firm (contract).

Proprietary security refers to officers directly employed by the property owner or company they protect — an in-house security department. Contract security refers to officers employed by an outside, licensed Private Patrol Operator (PPO) and assigned to a client's site under a services agreement.

Each model has tradeoffs: proprietary security can offer deeper institutional knowledge and direct management control, while contract security typically offers more staffing flexibility, shared overhead costs, and access to a licensed company's training infrastructure, insurance, and supervision structure.

Both models are subject to underlying BSIS registration requirements for individual guards; the distinction is about the employment and licensing structure, not a different legal standard for the officers themselves.
