Surveillance by our private detectives in Troisdorf

The medium-sized city counts 77,753 inhabitants (2016) and is located in the district Rhein-Sieg-Kreis, between Cologne and Bonn. Our seasoned private detectives in Troisdorf are approached with a wide range of cases: The question if the spouse is faithful needs to be solved just like the question if the child of a marriage is safe with the ex-partner or the custodial parent. Missing persons, including a child that has run away or a lost dementia patient; debtors or ex-partners who have disappeared to avoid their obligations of paying rent, child support or alimony; offenders who do a runner after a burglary or vehicle theft – all of them are the target of our detective agency in Troisdorf.


Through professional investigations, we acquire valid evidence which we hand over to our client, allowing them to assert their claims in court. Gladly we will also work on your case. Please, send us an email with your request through our contact form or give us a non-binding call.

Industry and logistics – a wide area of operation for criminals

The economic power of Troisdorf mainly consists of the chemical industry, with companies such as Evonik Degussa, as well as the machine engineering industry, the steel industry, and the logistics sector. While the manufacturing companies see themselves faced with espionage, bribery, sabotage and company data theft, our corporate detective agency in Troisdorf solves cases of cargo and warehouse crime, burglary and theft on behalf of the logistics sector. All industries have one thing in common: delicts committed by an employee, including false claims for wages, additional occupations that are permitted by the employer and fraudulent sick leave.


The number of cases related to cybercrime has also been continuously growing throughout the past few years. Reckless handling of sensitive data and the internet opens countless opportunities for offenders. Next to our experienced corporate detectives in Troisdorf, the certified IT experts and security specialists of the Kurtz Detective Agency will also help you prevent crimes, in the first place, through analogue and digital ways of precautionary security arrangements. After a crime has been committed and damaged you or your company, our investigators will support you to solve the case and seize the offender. We collect our investigation results in a detailed and valid investigation report. We will gladly advise you on your respective options of preventive security arrangements, or on damage claims, in a non-binding informational interview: +49 228 2861 4084.
