Minimization, access restriction, and legal requirements when handling sensitive information.
Updated 3 August 2026 · 7 minute read
An investigation by definition deals with sensitive information - about the client, the subject of verification, and third parties who are not party to the conflict at all. Professional standards require not collecting more than necessary, restricting access, and handling data so that the work itself does not create a new risk.
The material describes the practice: the principle of data minimization, division of access within the project team, procedures for handling third-party materials, requirements for delivering the result, and the matter of deleting materials after the project is completed.
