Principles by which we operate


Our proof is valid in court

DETEK knows the legal possibilities and limits of detective work by heart. We do not only want to obtain information for you. The evidence should be valid in court. To be able to guarantee this, we work closely with your legal advisors. Or we develop a secure investigation strategy with our own legal department.


We work with professionals

We like to be prepared for all cases. This is why DETEK works with experts, who have proven their skills in various fields – such as criminalistics, anti-eavesdropping measures, law, economics, IT, technology, finance or culture. Therefore we can bring together a team according to your needs. To ensure we will have appropriately trained and qualified personnel at all times, we offer targeted training and further education through our subsidiary Deutsche Akademie für Ermittlungsdienste GmbH.


Called today – on-site tomorrow

24 hours a day, 7 days a week - we are here to listen to your case around the clock. If immediate action is required, call DETEK. Together we discuss, which procedure is productive in your case. And then start the mission as soon as possible.


Your case is unique

You know about your request. DETEK has an overview of the possibilities of detective work. Together we find out which personnel, which strategies and which technique your individual case needs. If necessary, we even create new investigation methods for unusual scenarios. Our field of work makes a strong standardization impossible anyway.


We stay in touch

During investigation, we will update you promptly, comprehensively and honestly. We want you to understand when we act in your case – and which amount of effort and money is involved. At the same time DETEK would like to give you the opportunity to set your own impulses and to change the approach as required.


Our eyes are everywhere

In addition to numerous operations centers at home in Germany DETEK has agencies in London, Marbella and Zurich. Thanks to our cooperation network, we can even support you worldwide – with detectives, who communicate in the local language and know the local manners as well as the economic and legal framework.

Data security

Your data is strictly confidential

Protecting your data is one of the most important tasks for us. All information you provide to DETEK is subject to strict security and confidentiality standards. These include, for example, safe IT systems and limited access rights. Only investigators working directly on your case may learn more about you. Our employees are also committed to secrecy. In case of non-compliance, they can be prosecuted. When we hire third parties to assist, they must first agree to our privacy standards - and let us check them accordingly.
