- Guard Licensing
- State or provincial certification required before a security officer may legally perform armed or unarmed guard duties, typically including background checks, training hours, and a written exam.
- Post Orders
- Written instructions issued to security officers for a specific assignment, detailing duties, escalation procedures, and conduct expectations at that site.
- Unarmed vs. Armed Services
- Unarmed security involves patrol and access control without weapons; armed security requires additional firearms licensing, training, and liability insurance.
- SIA Licence / Guard Card
- Jurisdiction-specific credentials β called a Guard Card in most US states and an SIA licence in the UK β authorizing an individual to work as a security officer.
- PSIRA
- Private Security Industry Regulatory Authority β South Africa's regulator for private security firms, used here as shorthand for the category of national security industry regulators found in many countries.
- Contract Security
- Security services provided by a third-party firm under a service agreement, as opposed to proprietary security employed directly by the client.
- Revenue per Officer (RPO)
- Total billable revenue divided by the number of deployed security officers β a key operational efficiency metric for staffing-intensive security firms.
- Bill Rate vs. Pay Rate
- The bill rate is what the client pays per officer per hour; the pay rate is what the officer earns. The spread between the two, minus overhead, is the gross margin.
- Loss Prevention
- Security services specifically focused on reducing theft, fraud, and inventory shrinkage β common in retail, logistics, and warehouse environments.
- Patrol Density
- The number of security officers or patrol units assigned per square foot or per site, used to price contracts and demonstrate coverage capacity to clients.
