05How we work

Investigative by origin. Evidence-based. Decision-focused.

The question is not only “who did it” but “how was it possible in this company.”

Defensible findings in five steps: each engagement is planned according to the nature of the allegation, the company's structure, and existing risks; results are reported in a manner suitable for presentation to management, legal teams, or courts.

01

Preliminary assessment

The nature of the allegation, ongoing damage, and risk of evidence loss are evaluated.

06Risk measurement

How prepared is your company for these risks?

“It could not happen here” is not a control; it is a blind spot. Fraud is no longer the exception; it is a risk companies face routinely. Figures from Türkiye:

85%

Approximately 85% of companies detected at least one fraud case in the last two years.

50%

Only 50% of cases are detected within the first year.

Question 1 / 3 · Control / Opportunity

Is there a lack of segregation of duties, or is payment approval concentrated in a single person?

These three questions are taken from the 21-question Fraud Risk Simulator; your answers carry over, so you continue where you left off. Full assessment: 6 risk areas based on the ACFE fraud triangle, ~5 minutes, 0–100 score, key findings, and downloadable PDF report.

Personelini Tanı™

Hiring right is the first step to preventing fraud.

64% of fraud in Türkiye is committed by employees.*

A platform that verifies candidate documents — diploma, ID, criminal record, social security (SGK) — against official sources. The candidate uploads the document from e-Devlet, the system queries the source, an expert approves; the sealed report can be checked on a public verification page.

How we work with corporate clients, law firms, and international peers

Corporate clients

Direct engagement; scope, reporting line, and confidentiality are defined in the first consultation. Where management itself is the subject of the examination, the engagement and reporting run through the board of directors or the audit committee.

Law firms

Engagement through counsel; chain of custody, court-ready reporting, and expert-witness support are structured with the legal team from the start.

International peers

Your local partner in Türkiye: public-records and title searches, ultimate beneficial owner (UBO) identification, field verification; reporting in English.

Fraud progresses unseen for months.

Trust is not a control mechanism. A case goes undetected for a median of twelve months; one caught within six months costs around $40,000, one that runs past five years more than $1.1 million. If you have suspicions, do not wait; the initial consultation is without obligation.

Let's evaluate your situation together.

The initial consultation is confidential and without obligation. If there is an ongoing loss or risk of evidence loss, skip the form and call.

  • 1 · Confidential first conversation — We listen to the situation and its urgency.
  • 2 · Preliminary assessment note — The nature of the allegation, available information, and risks are assessed; a scope proposal is presented.
  • 3 · Scope and start — Purpose, authority, information sources, and reporting line are agreed together.

Commitment begins only when the scope is approved.
