Office Security for Corporate Buildings: Reception, Access and After-Hours
Written by Paul Thandi, Operations Manager, On Guard Security Ltd. — 10+ years in BC security · Updated September 2026
A head office holds more than furniture and laptops. It holds client files, contracts, payroll records and the people who run the business, and on any given day it welcomes staff, visitors, couriers, cleaners and contractors through the same front door. Good office security lets all of that traffic flow smoothly while making sure only the right people get past reception. On Guard Security Ltd. provides licensed guards for corporate buildings and offices in Surrey, Vancouver, Burnaby, Richmond, Langley, Abbotsford and across the Lower Mainland. This page explains what a reception guard does, how to think about access inside the building, and how after-hours coverage works.
Key takeaways
Office security is the protection of an office’s people, property and information through controlled access, visitor management, patrols and after-hours checks.
The reception desk is the most important security point in most offices: it is where public space ends and the working office begins.
Thinking of the building in zones (public areas, reception, working areas and restricted rooms) makes it clear where guards and access controls belong.
After hours, many offices move from a staffed desk to mobile patrols and alarm response.
On Guard Security Ltd. provides licensed, JIBC-trained, unarmed guards with 24/7 support. We provide access control at meeting rooms and executive floors, not close protection.
In most corporate buildings the front desk decides who gets in. A security officer at reception greets people, confirms appointments with the host, signs visitors in, issues passes, and keeps an eye on the doors and elevators. When it is done well, visitors experience it as good service; the security is barely noticeable.
A reception guard’s typical duties include:
Checking in visitors and contractors, calling the host and issuing and collecting visitor passes
Watching for tailgating through turnstiles, fob doors and parkade entrances
Logging deliveries and directing couriers to the right place so they don’t wander the floors
Answering questions from staff and visitors and helping during a fire alarm or evacuation according to the building’s plan
Recording incidents and passing on anything unusual to the office manager or facilities team
Our guards are trained for large office buildings, where hundreds of people may come and go in a day. Before a guard starts, we agree the visitor procedure with you: who can authorize guests, what ID is needed, which areas visitors can enter unescorted, and what happens when a host can’t be reached.
Key insight: Most unwanted entry into offices isn’t forced. It happens because someone confidently follows a staff member through a door. A guard at reception who politely asks everyone the same question stops most of it.
A helpful way to plan office security comes from the Government of Canada. The RCMP’s Guide to the Application of Physical Security Zones is written for federal facilities, but its idea of progressively restricted zones translates well to private offices. It describes a Public Zone (such as elevator lobbies in a multi-occupancy building), a Reception Zone where the move from public to restricted space is controlled and visitors first make contact, and an Operations Zone, typically open office areas, limited to the people who work there and escorted visitors. It also sets out stricter Security and High Security Zones.
Zone (federal model)
In a typical office
How guards support it
Public Zone
Building entrance, shared elevator lobby, parkade
Patrols, watching for loitering and tailgating at entry points
Reception Zone
Front desk and waiting area
Visitor sign-in, passes, confirming appointments with hosts
Operations Zone
Open-plan work areas and meeting rooms
Escorting visitors, challenging unfamiliar people politely, floor rounds
Restricted rooms
Server rooms, records storage, executive suites
Door checks, access logs, posts outside rooms during sensitive meetings
Access cards, cameras and locks do much of the work in each zone. Guards make sure the rules are actually followed and deal with the exceptions: a visitor without a host, a propped door, a contractor asking to be let into a comms room.
Some days need more than the usual front desk: a board meeting, a visit from important clients, an all-staff event or a sensitive announcement. We can post a guard outside the meeting room or at the executive floor lobby to make sure only invited people go in, and to keep curious visitors and couriers away. For larger gatherings, our event security team can handle registration and entry.
We’re clear about what this is. It is access control at a door, not personal protection. On Guard Security Ltd. provides unarmed guards and doesn’t offer bodyguard or close-protection services.
Information matters too. Guards can check that confidential documents aren’t left at printers or in unlocked meeting rooms at the end of the day, and report unlocked filing rooms or unattended laptops to the office manager under your clean-desk policy.
Once staff leave, an office has different risks: doors left unlocked, cleaners and contractors working late, alarms that go off at 2 a.m. and nobody there to check. Common after-hours set-ups are:
Evening desk coverage until the last staff and cleaners leave, followed by a lock-up round
Mobile patrol visits overnight and on weekends to check doors, the parkade and the building perimeter
Alarm response, where a guard attends activations, checks the premises and reports back
Key insight: After-hours office security is mostly about consistency. The same lock-up checks, done every night and written down, catch the unlocked side door long before it becomes a problem.
Offices in a multi-tenant commercial property or business park may be better served by property-wide commercial security. If you’re comparing service types for the first time, our guide to what a security company does sets out the options.
We’re locally owned, based at 12565 88 Ave in Surrey, and have more than 10 years in BC security. Every guard is licensed and JIBC-trained, and new hires spend a week training one-on-one with a senior officer before working alone. You can confirm any guard’s or company’s licence with the province’s licence status verification tool. We’re WorkSafeBC compliant, fully insured and available 24/7, and we plan each site around your procedures, for short-term needs or long-term contracts.
Office security is the protection of an office’s people, property and information. It combines physical measures such as locks, access cards and cameras with procedures such as visitor sign-in, and with guards who control reception, patrol the building and respond to alarms after hours.
What are the 7 types of security?
There is no standard list of seven. Lists online vary by source and usually mix physical security with personnel security, information security and several kinds of cyber security such as network, application and cloud security. A guard company like On Guard Security Ltd. covers the physical side: people, doors, visitors and patrols.
Can your guards protect executives or VIP visitors?
We can control access to executive floors and post a guard outside meeting rooms so only invited people enter. We don’t provide bodyguard or close-protection services, and our guards are unarmed.
What security does an office need after hours?
Many offices use evening desk coverage until cleaners leave, a lock-up round, then mobile patrol visits and alarm response overnight and on weekends. Buildings with frequent late work or valuable equipment may keep a guard on site all night.
Do your guards manage visitor sign-in and passes?
Yes. Reception guards sign visitors in, confirm the appointment with the host, issue and collect passes and log contractors and deliveries, using your visitor system or a paper log if you don’t have one.

We used On Guard for our building while we were transitioning to our new intercom and entry system. They were always incredibly professional to deal with and the guards showed up well ahead of time and did a great job as we went through the process, which extended longer than expected. On Guard was also great at getting somebody on site the first night we needed them on very short notice. Overall, we were extremely happy with their service.
