Our approach

1. Confidential conversation: tell us what happened and what you need to know.

2. A plan before we start: we'll explain the approach and quote the work up front.

3. Investigation: facts gathered lawfully and discreetly.

4. Findings: we report back what we found so you can decide what to do next.

When to call an investigator

• You suspect theft or inventory loss but can't prove who is responsible

• A workplace concern needs to be looked into independently

• A security incident at your property needs follow-up

• You need facts before you make a decision

Investigations and security, together

Because we also provide licensed armed guard and unarmed guard security services, we can do more than hand over findings. If an investigation uncovers an ongoing theft problem, a threat or a vulnerable site, we can put officers, mobile patrol or loss prevention coverage in place, so the findings become protection.
