Security Guarding
Guarding built around your risk
SIA-accredited guarding for corporate, transport, and residential sites, backed by risk assessment, national coverage, and the wider MAST security offering.
Security Guarding
A guard is only as good as the standard behind them
Manned guarding is the most visible layer of physical security and the most variable in quality across the industry. The difference is in accreditation, vetting, risk assessment, and the wider capability standing behind the officer on site. MAST holds Approved Contractor Scheme status and provides national man guarding.
Guarding aligned to your risk
We begin with a customised risk assessment, so the security plan aligns with what your site actually needs rather than a standard package. From there we deploy SIA-accredited officers, scaled to the risk, from a single officer to a coordinated team. Our Approved Contractor Scheme status means quality and compliance are independently assured against industry standards, and our man guarding capability is national in reach.

SIA-accredited officers, scaled from a single post to a full team.

A customised assessment so the plan fits the site.

A track record with demanding clients
Our guarding is trusted by blue-chip organisations across corporate, transport, and residential sectors. That experience shapes how we recruit, brief, and supervise: to the standard those environments demand. Guarding also connects to the wider MAST offering. Where a site needs technical installations, canine units, consultancy, or a response capability, the same company provides it, coordinated rather than contracted out.
Trusted by demanding clients.
“MAST’s mobilisation for The Art of Banksy has been one of the most impressive elements of their service provision to RSEL. The turnaround of quote, to site review, to have staff on site was incredibly quick and under 10 days. Within that timeframe, Adam, Billy and the rest of the team (excuse those I’ve forgotten) ran through their processes at an impressive speed to help ensure we not only had onsite security provision but also assistance with the requested CCTV installations. Overall we cannot fault Mast for their service and provisions. We’re delighted with the initial service, and any queries or questions have been resolved quickly and without hesitation. TPO will be considering MAST for future security services across our host of events, exhibitions and venues.”
