What Does a Security Guard Actually Do?

Don’t believe the Hollywood stereotypes.
 Professional security guards are trained to:

  • Deter crime through presence and patrols
  • Observe and report—identify risks, document incidents, and spot suspicious activity
  • Respond to emergencies (trespassing, alarms, medical events, disturbances)
  • Enforce site rules and company policies
  • Assist employees, residents, visitors, and customers
  • Work with law enforcement and first responders when needed

Most days, a security guard’s work is about prevention—not confrontation. But when it counts, a real professional knows how to respond.

Core Duties of Security Guards

Typical Security Guard Duties

Patrolling property by foot or vehicle
Monitoring surveillance cameras and alarm systems
Checking doors, gates, windows, and restricted areas
Responding to alarms, disturbances, or suspicious activity
Writing detailed incident and activity reports
Providing customer service to anyone on-site
Supporting property managers or facility staff
Effective security guards are trained in communication, de-escalation, and quick decision-making—not just standing around.

Unarmed Security Guards: When and Why

Unarmed security guards are the right choice for most properties, businesses, and residential communities—especially where the primary concern is trespassing, theft, vandalism, or enforcing property rules.

Common Sites for Unarmed Security Guards

Apartment complexes and HOAs
Office buildings and business parks
Hotels, retail stores, shopping centers
Construction sites, warehouses, and distribution centers

Report suspicious activity and safety issues
Offer fast response to minor incidents and emergencies
Deliver safety and customer service for residents, tenants, and staff
Pros: Lower cost, less liability, fits most general security needs
Cons: Not appropriate for sites facing credible armed threats

Armed Security Guards: When You Need More

Armed security guards are required for properties at higher risk—where there is a real threat of violence, high-value assets, or a history of serious incidents.

Where Armed Security Guards Are Essential

Banks and financial institutions
Jewelry stores and high-value retail
Cannabis dispensaries, pharmacies, and sensitive facilities
Critical infrastructure and government buildings
Sites with credible threats or recent incidents

What Armed Security Guards Offer

How to Choose the Right Security Guard

For most properties: Unarmed security guards provide reliable protection at a reasonable cost.
For sites facing real threats or protecting high-value assets: Armed security guards are non-negotiable.
Don’t guess—assess your risks honestly.
 The wrong guard can mean wasted money, higher liability, or even reputational damage.
