How to choose a security company for a business

What to check before you ask for quotes, and what to ask once you have them

Published 26 September 2026 · Last updated 26 September 2026

A security company becomes part of how your business runs: its people hold your keys, open your doors and decide what happens when something goes wrong. Price matters, but the cheapest quote is rarely the cheapest outcome if the service doesn’t turn up, doesn’t report, or can’t show it is licensed for the work.

This guide sets out what to check before you ask for quotes, and the questions that separate a well-run provider from one that simply fills shifts.

Before you ask for quotes

Write a one-page brief first. Providers can only quote accurately against a clear scope, and a written brief makes quotes comparable.

• What you need protected and why: stock, staff, the public, equipment, after-hours access.
• Hours and days, including public holidays and seasonal peaks.
• The service type: a static guard, mobile patrols, alarm response, CCTV monitoring, or a mix. If you’re unsure, see static guards vs mobile patrols.
• Site facts: entry points, parking, lighting, existing cameras and alarms, where a guard can take a break.
• What “good” looks like: patrol frequency, response times, and what you expect to receive in reports.

Ask at least three providers to quote against the same brief, and ask each to list what is not included.

Licence and insurance questions

Security work is licensed by each state and territory, and the rules differ. A company usually needs a business licence, and each person doing the work usually needs their own individual licence for that type of work. Our guide to checking a security provider’s licence explains how to confirm both.

Ask the provider for:

• The business licence number and the state that issued it, then look it up on the regulator’s register yourself.
• Confirmation that every officer on your site holds a current individual licence for the work they will do, such as crowd control rather than static guarding where that distinction applies.
• Certificates of currency for public liability insurance and workers’ compensation, and professional indemnity if they are giving advice or designing systems. Check the insured name matches the business you are contracting with.
• Whether they subcontract any shifts, and if so, how subcontractors are licensed, insured and supervised. In some states a business that supplies workers to your site may also need a labour hire licence; ask whether that applies.

A provider that hesitates to put these in writing is telling you something.

Experience with similar sites

A company that guards construction sites well may not suit a shopping centre, a warehouse or a medical practice. Ask:

• What sites like ours do you currently look after, and for how long?
• What problems are typical on sites like this, and how do you deal with them?
• Can we speak to a current client with a similar site?

Listen for specifics: how they handle after-hours contractors, aggressive customers, false alarms or a forced door. General answers about “professional, reliable service” don’t tell you much.

Staffing and supervision

The quality of a guarding service depends on who turns up and who checks on them.

• Continuity: will the same officers work your site, or whoever is available? Regular officers learn the site, the people and what looks out of place.
• Site induction: who briefs new officers, and is there a written site instruction they must read before their first shift?
• Supervision: who is the supervisor or account manager, how often do they visit, and how do they check officers are patrolling and not just present?
• Fatigue and breaks: how long are shifts, and who relieves an officer for breaks on a single-officer site?
• Replacements: how quickly can they cover an unexpected absence, and will the replacement be inducted?

Reporting and escalation

Reporting is how you know the service is working. Agree it before the contract starts.

• Routine reports: what is recorded each shift (patrols completed, doors checked, visitors, hazards), and how you receive it.
• Incident reports: what counts as an incident, how quickly you’re told, and what a written report contains.
• Escalation: who the officer calls, in what order, and when police, emergency services or your own staff are contacted. Write this down as a contact list and keep it current.
• Evidence: whether patrols are verified (for example, with checkpoints or GPS), and whether photos are taken.

Contract terms and cancellation

Read the contract as carefully as the quote.

• Term and notice: how long is the minimum term, and how much notice is needed to end it? Avoid long lock-ins for a new provider.
• Price changes: when can rates rise (for example, with award wage changes), and how much notice do you get?
• Minimum charges: minimum shift lengths, call-out fees and public holiday rates.
• Service levels: what happens if a shift is missed or a response is late, and whether you can end the contract for repeated failures.
• Keys and access: how keys, codes and cards are stored, logged and returned when the contract ends.
• Liability: what the provider accepts responsibility for, and any caps on it.

If the contract is large or unusual, have it reviewed before you sign.

A short checklist

1. Written brief sent to at least three providers.
2. Business licence checked on the regulator’s register, and individual licences confirmed for your site’s officers.
3. Certificates of currency received and names matched.
4. Similar-site experience and a reference checked.
5. Supervision, reporting and escalation agreed in writing.
6. Contract term, notice, price changes and minimum charges understood.

When you’re ready to compare businesses, browse security providers or go straight to security guards and patrol providers. Each listing shows the licence information available for it, which you should still confirm with the regulator.
