Infrastructure Security Services

Critical infrastructure requires a different approach to physical security.

Utilities, water and wastewater facilities, energy infrastructure, telecommunications sites, transportation facilities, public works operations, industrial facilities, and other essential properties can face threats involving unauthorized access, vandalism, theft, sabotage, workplace violence, equipment damage, and disruption of operations.

Patrol Guard Security Services provides professional infrastructure security services in Denver and throughout Colorado, including armed security guards, access control, gate security, perimeter patrols, mobile security patrols, employee and contractor verification, vehicle monitoring, and emergency security coverage.

Infrastructure security is not simply about protecting property. In many environments, security helps protect the people, equipment, systems, and facilities necessary to maintain essential operations.

Armed Critical Infrastructure Security

Certain infrastructure facilities may justify an armed security presence because of their importance, location, assets, or potential consequences of a serious security incident.

PGSS provides armed infrastructure security guards for appropriate facilities requiring enhanced protection.

Armed personnel can provide visible deterrence, monitor access points, patrol designated areas, protect employees and contractors, identify suspicious activity, respond to security incidents, and coordinate with law enforcement when necessary.

A firearm is a protective capability—not the infrastructure security plan itself.

Effective infrastructure security also depends on access control, physical barriers, surveillance, communication, procedures, supervision, documentation, and clearly established post orders.

Critical Infrastructure Security

Critical infrastructure includes facilities and systems whose continued operation can be important to public health, safety, commerce, government, or essential services.

The physical security requirements of these properties can differ substantially from those of conventional commercial buildings.

Facilities may contain restricted areas, specialized equipment, hazardous environments, sensitive operations, valuable materials, or systems that cannot tolerate unnecessary disruption.

PGSS can develop security around the individual facility rather than applying a generic security model to every infrastructure assignment.

Water & Wastewater Facility Security

Water and wastewater facilities require controlled access and protection of operational areas, equipment, employees, contractors, and infrastructure.

PGSS can provide armed guards, gate security, access control, employee and contractor verification, perimeter patrols, mobile patrols, parking security, and temporary coverage during construction or maintenance.

Security procedures can be developed around restricted areas, authorized access, deliveries, contractor activity, operating schedules, and facility-specific requirements.

Energy & Utility Security

Energy and utility properties can contain valuable equipment and systems that are important to ongoing operations.

PGSS can provide security for utility properties, electrical infrastructure, substations, energy facilities, equipment yards, storage locations, and other operational sites.

Coverage can include armed security, perimeter patrols, gate security, access control, vehicle monitoring, contractor verification, mobile patrols, and after-hours protection.

Security can also be temporarily increased during maintenance, construction, outages, threats, or periods of elevated concern.

Telecommunications Infrastructure Security

Communications infrastructure can be geographically dispersed and may contain valuable equipment in locations that are not continuously occupied.

PGSS can provide security for telecommunications properties, communications equipment, operational facilities, and other designated sites.

Depending on the property, coverage can include dedicated guards, access control, perimeter security, mobile patrols, equipment-area monitoring, and temporary protection following vandalism, theft, or damage.

Transportation Infrastructure Security

Transportation-related facilities can experience high levels of employee, contractor, vehicle, delivery, and public activity.

PGSS can provide physical security for transportation properties, maintenance facilities, equipment yards, parking facilities, administrative buildings, and other controlled locations.

Services can include armed security, access control, vehicle verification, perimeter patrols, parking security, mobile patrols, and incident documentation.

Public Works & Municipal Facility Security

Public works departments operate facilities containing vehicles, machinery, tools, materials, fuel, and other equipment necessary for municipal operations.

PGSS can provide security for maintenance facilities, equipment yards, storage areas, administrative buildings, and other municipal properties.

Security can include gate guards, employee and contractor verification, vehicle access monitoring, perimeter patrols, equipment protection, mobile patrols, and after-hours coverage.

Industrial & Manufacturing Infrastructure Security

Industrial properties can contain expensive machinery, raw materials, finished products, proprietary technology, equipment, vehicles, and restricted operational areas.

Security concerns can include theft, vandalism, unauthorized access, workplace violence, trespassing, sabotage, and disruption of operations.

PGSS can provide armed security, gate guards, access control, perimeter patrols, loading-area security, vehicle monitoring, employee escorts, and mobile patrols.

Security plans can account for shift changes, deliveries, contractors, restricted areas, production schedules, and after-hours operations.

Access Control & Gate Security

Access control is one of the most important components of infrastructure security.

PGSS personnel can verify employees, contractors, vendors, visitors, and delivery drivers according to procedures established by the client.

Security personnel can monitor credentials, maintain visitor records, control designated gates, verify authorization, monitor vehicle access, and document attempted unauthorized entry.

Access procedures should clearly define who is permitted onto the property, where they are authorized to go, and how exceptions are handled.

Contractor & Vendor Verification

Infrastructure facilities frequently depend on outside contractors, maintenance personnel, delivery drivers, vendors, and specialized technicians.

PGSS personnel can verify individuals and vehicles against client-established authorization procedures before allowing access to controlled areas.

Security can also document arrivals and departures, direct contractors to designated locations, and notify facility representatives when authorization cannot be confirmed.

Perimeter Security & Patrols

Infrastructure facilities may occupy large properties with fences, gates, equipment yards, remote buildings, storage areas, and other exterior assets.

PGSS can conduct foot and vehicle patrols around designated perimeter areas.

Patrols can check gates, fencing, building exteriors, equipment areas, parking lots, access points, and other locations identified in the site’s post orders.

Randomized patrol schedules can reduce predictability while maintaining a visible security presence.

Mobile Patrols for Remote Infrastructure

Some infrastructure operators maintain multiple properties that do not require a dedicated officer at every location.

PGSS can provide scheduled or randomized mobile patrols between designated sites.

Mobile patrol officers can inspect entrances, gates, fences, buildings, equipment areas, parking areas, and other specified locations while documenting each patrol.

This can provide a practical security layer for remote or lightly staffed infrastructure.

Protection Against Theft, Vandalism & Sabotage

Infrastructure properties can contain valuable copper, tools, equipment, machinery, fuel, electronics, vehicles, and other assets.

However, financial loss is not always the greatest concern.

Damage to infrastructure can potentially interrupt operations or require substantial repair and recovery efforts.

PGSS security can provide visible deterrence, access control, patrols, observation, incident response, and documentation designed to reduce opportunities for unauthorized activity.

Workplace Violence & Employee Safety

Infrastructure and industrial facilities are still workplaces.

Threats involving employees, former employees, contractors, domestic situations, or members of the public can create serious concerns.

PGSS can provide additional armed security, access control, employee escorts, parking security, and temporary coverage following a threat or during higher-risk employee terminations.

Immediate or credible threats should also be reported to law enforcement.

Infrastructure Construction & Project Security

Infrastructure projects can involve expensive machinery, materials, specialized equipment, contractors, temporary access points, and changing site conditions.

PGSS can provide security during construction, expansion, repair, modernization, and other infrastructure projects.

Coverage can include armed guards, gate security, contractor verification, equipment protection, mobile patrols, overnight security, and perimeter patrols.

Security plans can change as the project progresses and access points or operational areas change.

Emergency Infrastructure Security

Infrastructure facilities may require immediate additional security following an unexpected event.

PGSS can provide temporary security following:

• Vandalism or attempted sabotage
• Burglary or theft
• Damaged fencing or gates
• Access-control failures
• Alarm failures
• Power outages
• Fire or flooding
• Severe weather
• Equipment damage
• Workplace threats
• Construction incidents
• Other security vulnerabilities

Temporary personnel can remain until normal security systems, barriers, or operating conditions are restored.

Security During Outages & Service Disruptions

Power failures, equipment problems, severe weather, fires, flooding, and other disruptions can affect normal security systems.

Electronic gates, cameras, alarms, lighting, and access-control systems may become unavailable or operate differently during an outage.

Temporary security personnel can provide a physical presence while normal systems are being repaired or restored.

Coverage can include access control, perimeter patrols, equipment protection, vehicle monitoring, and documentation.

Incident Reporting & Documentation

Accurate documentation is particularly important at infrastructure facilities.

PGSS personnel can document unauthorized access attempts, suspicious activity, damaged property, security-system problems, threats, safety concerns, contractor activity, law-enforcement response, and other significant incidents.

Reports should focus on observable facts and established security procedures.

Consistent reporting can also help facility management identify recurring vulnerabilities and determine whether security procedures should be modified.

Security Planning for Infrastructure Facilities

Infrastructure security should be developed around the actual property and operation.

Important considerations can include:

• Facility layout
• Critical assets
• Restricted areas
• Gates and access points
• Perimeter fencing
• Employee access
• Contractor and vendor access
• Vehicle traffic
• Deliveries
• Operating schedules
• Shift changes
• Remote equipment
• Existing surveillance and alarms
• Emergency access
• Previous incidents
• Identified threats

PGSS can use these factors to develop post orders and security coverage appropriate to the assignment.
