Insider Threat Assessment & Investigation

Triage the concern carefully

An unexplained loss, unusual access, information reaching a competitor or a report from a colleague can justify a review. The first step is to establish the facts available, the potential consequences and any immediate need to preserve records or restrict an exposure.

The brief should identify who is authorised to commission work, the roles of security, HR and legal advisers, and the purpose of each enquiry. Suspicion should not be treated as an established finding.

Examine evidence and controls

An assignment can combine background enquiries, examination of supplied records, interviews by appropriate specialists, digital forensic support and a review of access or contractor arrangements. The methods depend on the issue and the authority available.

The assessment also considers whether existing procedures create avoidable opportunities for loss or disclosure. A control weakness can matter even when the evidence does not establish individual wrongdoing.

Use tools in their proper role

Specialist analytical or screening tools may help organise enquiries, subject to an agreed purpose, suitability and appropriate safeguards. No analytical score or automated flag should be presented as proof of deception or misconduct.

The output distinguishes evidence, unresolved concerns and practical recommendations. Decisions affecting an employee, contractor or business partner remain with the authorised client and its advisers, using the relevant process and wider evidence.

What the engagement can deliver

The proposal confirms the outputs for your assignment. Depending on scope, these can include:

• An initial concern assessment and agreed investigation scope
• A sourced account of findings and outstanding questions
• A review of material access or process weaknesses where commissioned
• Recommendations for further enquiry and proportionate control improvements
