How to Audit Security Subcontracting Arrangements

Businesses that outsource security services may sometimes rely on subcontractors to deliver part of the agreed work. While subcontracting can help security providers manage staffing and operational requirements, it can also introduce additional risks if responsibilities, standards and reporting arrangements are unclear.

For businesses, reviewing security subcontracting arrangements is an important step towards understanding who is delivering the service, how performance is monitored and whether the agreed requirements are being met.

Here are seven areas to review when auditing security subcontracting arrangements.

1. Identify Who Is Delivering the Security Service

Start by confirming whether your security provider uses subcontractors and which parts of the service they perform.

Ask for clear information about the responsibilities of the main contractor and any subcontracted parties. This may include security guarding, mobile patrols, after-hours coverage or other agreed duties.

Businesses should understand who is responsible for managing the subcontractor and who should be contacted if a service issue occurs.

For example, businesses considering mobile patrol arrangements can review MBK Security Group's mobile patrol services to learn more about this type of security service.

2. Review Licences and Compliance Requirements

Security work is subject to applicable licensing and regulatory requirements. Businesses should establish what requirements apply to the services being delivered and verify that the relevant parties meet them.

Depending on the location and nature of the work, checks may include applicable security licences, staff authorisations, insurance documentation and other required records.

In Australia, security licensing requirements can vary between states and territories. Businesses should confirm the relevant requirements for the jurisdiction where the work takes place rather than assuming that one set of requirements applies everywhere.

Keep appropriate records of the checks completed and follow up on any missing or expired documentation.

3. Examine the Subcontracting Agreement

Review the agreement between the main security provider and the subcontractor, where access to relevant terms is available.

The arrangement should clearly define the services being delivered, each party's responsibilities and the standards expected.

Pay attention to:

• Scope of work and service coverage
• Reporting and communication requirements
• Performance expectations
• Incident escalation procedures
• Confidentiality and information handling
• Insurance and responsibility for relevant obligations
• Procedures for addressing service failures

Businesses should also review their own contract to understand whether subcontracting is permitted and whether approval or notification is required.

If any terms are unclear, seek clarification before relying on the arrangement.

4. Assess Staff Training and Site Knowledge

Subcontracted personnel should understand the requirements of the site where they are assigned.

Review how staff are inducted, how site-specific instructions are communicated and how changes to procedures are shared.

Relevant checks may include whether personnel understand access restrictions, emergency procedures, incident reporting expectations and the responsibilities associated with their duties.

Businesses should also consider how the main provider confirms that subcontracted personnel remain suitable for the work they perform.

A documented process can help maintain consistent service expectations across different teams.

5. Check Reporting and Incident Management

Consistent reporting is particularly important when security services are delivered by multiple parties.

Review whether incidents, patrol activities, site visits and service issues are recorded in the agreed format and provided to the appropriate contacts.

Check that the reporting process identifies who is responsible for investigating an issue, communicating updates and confirming that corrective action has been completed.

For example, if a subcontracted patrol officer identifies an access problem, the business should understand how that information is recorded, escalated and followed up.

Clear reporting arrangements make it easier to monitor service delivery and maintain accountability.

6. Monitor Performance and Service Quality

An audit should assess whether subcontracted services meet the agreed requirements in practice.

Depending on the arrangement, useful checks may include attendance records, patrol logs, incident reports, response times where applicable, customer feedback and records of missed or incomplete duties.

Compare the available evidence with the contract requirements rather than relying only on verbal assurances.

If problems are identified, document the issue, agree on corrective actions and establish a reasonable timeframe for review.

The main security provider should be able to explain how subcontractor performance is monitored and how repeated service problems are addressed.

Businesses can also review MBK Security Group's security alarm monitoring and rapid response services to explore another type of security arrangement that may require clear response and reporting responsibilities.

7. Review Risks and Corrective Actions Regularly

Subcontracting arrangements should be reviewed whenever there are significant changes to the service, personnel, site requirements or contractual responsibilities.

Keep a record of audit findings, outstanding concerns, responsible parties and agreed completion dates.

Where weaknesses are identified, decide whether additional monitoring, revised procedures or changes to the arrangement are needed.

Regular reviews help businesses identify problems early and ensure that subcontracting arrangements continue to support their operational and security requirements.

For businesses managing different types of premises, MBK Security Group's security services provide a starting point for exploring relevant security solutions.

Conclusion

Auditing security subcontracting arrangements helps businesses understand who is delivering their security services, whether relevant requirements are being met and how service quality is monitored.

By reviewing responsibilities, compliance records, agreements, staff readiness, incident reporting and performance, businesses can identify gaps and improve accountability across the service arrangement.

A structured audit process, supported by clear documentation and regular follow-up, can help businesses make more informed decisions about managing security contractors and subcontractors.
