What Does A Security Company Do?

A security company protects people, property and reputation. Here is what that covers in practice, and which services suit offices, venues and events.

What Does A Security Company Do?

By RMSS LTD · Updated 25 October 2026

A security company supplies trained people, and the planning around them, to keep a site, a building or an event safe. The work ranges from a single officer on a reception desk to hundreds of officers and stewards on a stadium event day. Most of what a good company does is quiet: preventing problems, noticing the small things and responding calmly when something does go wrong.

Manned Guarding

Security officers are present on site to control access, patrol, check visitors and respond to incidents. They record what happens in a log or report, so the client has a clear picture of the site and any trends. Manned guarding suits offices, venues, car parks, construction sites and any place where a visible, responsive presence matters.

Front Of House And Concierge Security

In a corporate building the security officer is often the first person a visitor meets. Front of house and concierge officers greet people, issue visitor passes, manage deliveries and control who goes where, while keeping the entrance welcoming. See our corporate security services for more.

Event And Stadium Security

Events bring thousands of people through a few entrances. Stewards and SIA licensed door supervisors manage queues and crowd flow, check tickets, carry out bag and body searches, support guests who need help and respond to emergencies. Our event and stadium security teams do this every week across the UK.

What A Good Company Does Behind The Scenes

  • Assesses the risk. A good supplier asks about the layout, opening hours, visitors, past incidents and the outcome you want before it proposes a team.
  • Writes clear instructions. Each officer should know the duties, the escalation route and who to call.
  • Recruits and checks. Officers in licensable roles must hold the right SIA licence, and the supplier should check it, not assume it.
  • Trains and briefs. Briefings before a shift or an event, and refresher training, keep standards high.
  • Supervises and reports. Supervisors check the team on the ground and clients receive reports they can act on.
  • Covers absence. If an officer is ill, a replacement arrives, and you are told.

What A Security Company Does Not Do

Security officers are not the police. They have the same legal powers as any member of the public, together with the conditions of entry set by the site or the event. Their job is to prevent, deter, observe, report and respond, and to call the emergency services when needed.

Choosing What You Need

Start with what you want to protect and when: people, stock, equipment, a brand, an event. A short conversation about your site, the hours and the risks is enough to shape a first plan. When you are ready, read our guide on how to choose a security company or tell us about your site or event.

Questions

Frequently Asked Questions

Do security guards need to be licensed?

In the UK, people doing licensable security work, such as security guarding or door supervision, need an SIA licence. A supplier should be able to show that the officers it sends hold the right licence. See our guide on how to check a security guard's SIA licence.

What is the difference between a security officer and a steward?

A steward guides and helps people, mainly at events. Security guarding and door supervision are licensable activities, so those roles need an SIA licence. A good supplier explains which roles it is sending and what each is licensed to do.

How do I know what level of security I need?

It depends on the site, the hours, the number of visitors and the risks. A supplier should ask about these and propose a plan, rather than offer a standard package.
