A Proprietary Private Security Officer (PSO) is a security professional who works directly for one employer and helps protect that employer’s people, property, and assets. Unlike security guards employed by security companies, a PSO provides security services only for the company that hires them.

Many people assume a Proprietary Private Security Officer (PSO) is simply another name for a security guard. However, California law treats these positions differently.

A Proprietary Private Security Officer is usually unarmed and works only for one employer. They provide security services only for that employer.

To qualify as a Proprietary Private Security Officer, the individual is generally expected to:

• Work exclusively for one employer
• Provide security services for that employer
• Wear a distinctive uniform identifying them as security personnel
• Regularly interact with the public while performing assigned duties

Examples of businesses that commonly employ PSOs include:

• Hospitals
• Hotels
• Apartment communities
• Warehouses
• Manufacturing facilities
• Retail stores
• Corporate offices
• Educational facilities

Because PSOs often serve as the first contact for visitors, customers, vendors, and employees, professionalism is important. Strong communication skills are also key.

PSO vs Guard Card: Understanding the Difference

One common question from applicants is whether they need a Proprietary Private Security Officer registration.

Others ask if they need a Security Guard registration, often called a Guard Card.

The answer depends on who employs you.

A Proprietary Private Security Officer works directly for one employer.

They protect only that employer’s property, employees, and assets.

A Security Guard usually works for a licensed private patrol operator or security company.

They may be assigned to multiple client locations.

Choosing the correct registration is important because applying for the wrong credential can create delays in employment and licensing.

Annual Training Requirements for PSOs

Training does not end once a Proprietary Private Security Officer receives registration.
