If you've ever considered a career in security, you might be surprised by just how varied the role can be.
Modern security officers do far more than patrol buildings or monitor CCTV screens. On any given day, they might be welcoming visitors, managing access to a site, responding to incidents, supporting health and safety procedures, or helping people during an emergency.
It's a profession built on trust, responsibility and good judgement, and it offers opportunities to work across a huge range of sectors, from corporate offices and major events to construction projects, logistics sites, and critical infrastructure.
Whether you're exploring security as a new career or looking to take the next step within the industry, this guide explains what security officers do, the qualifications you'll need, the skills employers look for, and how to get started.
