This guide covers building-level security for owners and facility managers. For company-level office security, see office security in the Netherlands.
The security challenges specific to office buildings
Office buildings present a security profile distinct from retail, industrial, or hospitality environments. The legitimate user population is large, partially anonymous (visitors, service providers), and changes daily. The most common incidents — tailgating through access-controlled doors, theft of equipment or data from unattended offices, after-hours intrusion — are enabled by the same open-access culture that makes a building easy to work in.
Multi-tenant buildings add complexity: each tenant has different security requirements, different visitor profiles, and different after-hours access needs. A ground-floor lobby guard whose brief extends only to the building common areas cannot manage the security requirements of a law firm on the seventh floor and a logistics company on the second without a clear protocol for each. Single-tenant buildings face a different challenge — the security culture of the organisation operating the building determines how effectively the physical security infrastructure is used.
Manned guarding for office buildings
A licensed guard at a building reception desk is not simply a deterrent — the guard is the decision point for the entire visitor management process. A well-briefed guard checks visitor credentials, confirms appointments, issues access passes, escorts visitors to their destination, and monitors for individuals who do not follow access protocols. An under-briefed guard waves visitors through without checks and provides the appearance of security without the substance.
Mission Support assigns office building guards with a written site security plan covering the specific protocols for that building: visitor registration procedure, access-controlled floor management, out-of-hours access authorisation, and escalation chain for incidents. Guards are briefed on the specific tenant mix and any sensitivities — a building housing a financial services firm, an embassy, or a pharmaceutical research operation has a different guard brief than a generic commercial office.
Access control and visitor management
Physical access control — turnstiles, card readers, reception barriers — is only as effective as the process that governs it. An access control system that employees routinely tailgate through, or whose visitor passes are issued without identity verification, does not control access. Mission Support's site security plans include the access control protocol alongside the physical guarding specification — the guard and the system must work together.
Visitor management for office buildings requires a consistent process: advance registration or appointment confirmation, identity verification on arrival, time-limited access credentials, escort or supervised access for sensitive floors, and a departure record. For buildings with multiple tenants, the ground-floor reception guard coordinates the visitor management process for all tenants against a master system that each tenant populates with their expected visitors.
After-hours and weekend security
The majority of office building intrusions occur after business hours, when the building is empty and the response time for any unnoticed incident extends from minutes to hours. After-hours security for office buildings typically involves a combination of alarm monitoring with mobile response, periodic patrol visits by a roving guard unit, and a clear escalation protocol for the alarm monitoring centre.
Mission Support provides after-hours alarm mobile response services coordinated with the daytime guarding contract: the same security management team that designs the daytime guard specification also designs the after-hours response protocol, ensuring continuity. Contact Mission Support to discuss your building's specific after-hours requirement.
Frequently asked
How many guards does an office building need?
Guard count depends on building size, number of access points, visitor volume, and the hours of coverage required. A single-entrance office building with moderate visitor traffic may require one guard per shift. Multi-entrance buildings with high visitor throughput or sensitive tenants may require two or more. Mission Support conducts a site assessment and produces a specific staffing recommendation before any engagement.
Can Mission Support manage the security for a multi-tenant building on behalf of the landlord?
Yes. Mission Support works with building owners and managing agents to deliver a ground-floor security function that serves all tenants. The arrangement includes a master visitor management system, tenant-specific access protocols, and a single point of contact for all security matters — simplifying management for the landlord and delivering consistent quality to each tenant.
What certification do Mission Support guards carry?
All Mission Support guards hold a valid beveiligerspas issued under the Dutch Wpbr (Wet particuliere beveiligingsorganisaties en recherchebureaus). Mission Support operates as a licensed Wpbr security organisation. Guards assigned to specific buildings are briefed on the site security plan before their first shift.
