How we work

Direct involvement in every case.

At Prosecure every case is handled at founder level; its strategic responsibility is not passed down to someone else. Hasan Alsancak conducts the initial consultation, defines the scope and the investigation plan, evaluates the critical findings and signs the final report. Where necessary he takes part in field work and gives evidence in court proceedings.

A team is assembled according to the nature of the case, drawing on forensic accounting, digital forensics, field research, an international correspondent network and legal counsel; every member is engaged only after a confidentiality agreement (NDA) and a conflict-of-interest check.

Responsibility for the case rests, from beginning to end, with a person you know by name.

What this experience means for your case

What does this experience provide today?

Setting the investigation up correctly

Field and intelligence experience gained in public investigations makes it possible to define the scope of the matter, the points to be examined and the critical evidence correctly at an early stage.

Seeing the corporate risk

Senior assignments at the United Nations and at global energy companies bring the experience of assessing a finding not only as an incident, but in terms of management, operational and reputational risk.

Producing a result you can act on

The purpose is not to collect information, but to reduce uncertainty and set out a clear picture on which management can decide with confidence.
