Writing the CV for the security guard role
Start your CV with the type of sites where you worked and your security guard diploma. Then put your first aid (EHBO) certificate directly beneath it. That way the reader sees in the first lines which sites you know and which diplomas you hold.
In this role you check access, report incidents and stay calm during conflicts. The type of site, the shifts and the valid diplomas are concrete points you can name in your CV. A client can then check those details quickly.
What you do in this role
A site security guard checks access and identification, patrols the premises at fixed times and records deviations. In the event of an incident the guard describes what happened and reports it according to the protocol. In conflicts the guard stays calm and decides when the police need to be called in.
Keep the CV to one or two pages.
How your CV matches the advert
Read the advert and note the type of site, the shifts and the requirements for diplomas and first aid. Put in your CV which of those points you already hold, with their validity. A client wants to check quickly whether you meet the requirements, so make the details easy to find.
Security is about access, patrolling and reporting. Describe in your CV how you reported an incident: what you saw, when you reported it and whom you informed. That shows how you work with the procedure, and is more concrete than a general statement about reliability.
Check the diploma details, the names of the sites and the validity. Read your CV aloud and cut sentences you cannot back up. A short, factual CV with the diplomas at the top suits the work.
Access control requires consistent action, even when someone insists. Describe in your CV how you dealt with a visitor without access, for example by following the procedure and informing the site manager. That shows the reader you follow the rules, without needing the word strict.
Patrolling is also about what you notice. Describe in your CV which deviations you saw, such as a door that should have been closed, and how you reported them. That keeps the CV to concrete observations, which are easy to discuss in an interview.
A site changes during a shift, for example through work being carried out, deliveries or visitors arriving later. Describe in your CV how you kept track of those changes in your round or logbook. That shows you follow the situation throughout the shift, not only at the start of your round.
