What We Offer
Security services built around real operating demands.
From visible guarding to monitoring, patrols, and event coverage, we deliver protection services that keep sites controlled, professional, and ready to respond.
Core Service Lines
Six focused ways we protect people, property, and operations.
Each service can operate alone or as part of a wider protection model depending on your site footprint, occupancy, and risk profile.
Security Guarding
Visible officer presence for daily site reassurance.
Professional guards who support safety, access awareness, and structured incident handling across business and residential environments.
- Front-of-house and perimeter visibility.
- Professional site representation.
- Supervisor-led reporting and escalation.
Monitoring and Screening
Live oversight that strengthens awareness beyond the gate.
Monitoring workflows and thermal support help maintain continuity, detect issues early, and keep response decisions informed.
- 24/7 watchfulness and escalation support.
- Thermal screening when required.
- Faster incident visibility for clients and supervisors.
Access Control
Manage movement through reception points and restricted zones.
We help clients maintain clear entry discipline, reduce unauthorised access, and improve accountability across staff and visitor traffic.
- Controlled visitor and contractor handling.
- Reception and gatehouse support.
- Structured entry logging and escalation.
Event Security
Protect guest experience while keeping the environment controlled.
Our event teams support stewarding, queue management, guest entry, and coordinated incident response for public-facing environments.
- Crowd-safe entry and movement management.
- Professional public-facing officers.
- Structured coordination during peak periods.
Mobile Patrols
Out-of-hours checks, lock routines, and wider footprint coverage.
Patrol-led services help maintain deterrence, secure openings and closures, and add reassurance where full-time static cover is not required.
- Scheduled and reactive patrol attendance.
- Lock and unlock support.
- Perimeter awareness for larger sites.
Door and Specialist Support
Additional cover for venues, high-footfall sites, and higher-risk periods.
We provide door supervision and specialist support options where environments need tighter entry handling or stronger visible deterrence.
- Door supervision and venue entry control.
- Canine and specialist deterrence support.
- Flexible reinforcement for changing conditions.
Delivery Standard
What every Onyx Guardian deployment includes.
Services are delivered through a consistent operating structure so clients get dependable cover and clear visibility, not fragmented support.
Site briefing
We align coverage to layout, occupancy, access routes, and the practical risks of the environment.
Visible supervision
Officers and supervisors work from a clear service plan with defined reporting expectations.
Incident logging
Observations, issues, and actions are documented so clients retain visibility and accountability.
Escalation readiness
We stay prepared to adapt staffing, involve supervisors, or strengthen support when risk conditions shift.
Specialist Support
Canine teams and high-deterrence support when the brief demands it.
Approved subcontractor partners extend our coverage model for larger footprints, open environments, and higher-attention risk periods.
- Enhanced deterrence for expansive or exposed sites.
- Experienced handlers for proactive risk identification.
- Flexible reinforcement when operational conditions tighten.
Additional Coverage
Reception, concierge, and customer-facing security.
Ideal for developments, hotels, offices, and mixed-use sites where service quality matters as much as control.
Operational Support
Key holding, alarm response, and gatehouse routines.
Added support for out-of-hours continuity, property access, and site opening or closing procedures.
Sector Flexibility
Construction, industrial, retail, and facilities coverage.
We adapt service style to the environment rather than forcing a single model onto every site.
Event Reinforcement
Private parties, public events, and high-footfall moments.
Teams can scale around attendance, access complexity, and the need for added supervisory support.
Where Services Fit
Coverage designed for a range of operational settings.
We shape the service mix around how each site works, what it needs to protect, and how visible security should feel to the people using it.
Business Sites
Offices, receptions, and commercial premises.
Support daily operations with controlled access and professional officer presence.
Residential Estates
Managed developments, concierge desks, and shared spaces.
Maintain reassurance, resident experience, and response readiness.
Events and Venues
Guest entry, stewarding, and crowd-safe movement.
Match service levels to attendance, layout complexity, and public visibility.
Industrial and Open Sites
Patrol-led coverage for larger perimeters and changing risk periods.
Combine patrols, deterrence, and escalation planning for wider environments.
