- FAQ
Frequently asked questions
How exactly does a professional detective agency work and how does cooperation begin?
The process at our detective agency is designed to ensure maximum discretion and effectiveness. It all starts with a confidential consultation, during which we analyze the specifics of the case and define the goals to be achieved. Then, we develop a personalized operational strategy – selecting appropriate methods, such as discreet observation, link analysis, or advanced intelligence. We use licensed detectives and state-of-the-art OSINT (Open Source Intelligence) tools, which allows us to quickly and reliably collect evidence. The end result is a detailed report on the course of action, containing documented facts, photos or recordings, which in many cases constitute key evidence in court cases.
Why is it worth entrusting your case to the REKS Detective Agency?
By choosing our detective agency, you gain a partner who combines traditional detective work with modern data analytics. Our greatest advantage is our interdisciplinary approach – we don’t limit ourselves to field observations, but also conduct in-depth digital investigations and business analyses. We specialize in both private matters and complex commercial assignments throughout Poland and the European Union. We guarantee absolute confidentiality (professional secrecy), professionalism, and full transparency of settlements. Our experience allows us to solve cases that others may consider hopeless or overly complex.
Are the services provided by a detective agency fully legal and is evidence admissible in court?
Yes, every service provided by our detective agency is conducted in strict compliance with applicable Polish and international law. We hold all necessary detective licenses and are entered in official registers, guaranteeing the legality of our operations. This is crucial, as only materials legally collected by a licensed detective can be effectively used as evidence in civil, criminal, or divorce cases. We gather information in a manner that complies with the law, while ensuring that clients receive irrefutable confirmation of the facts.
What does professional contractor verification and business intelligence involve?
W jaki sposób przebiega ustalanie niewierności małżeńskiej i czy jest to dyskretne?
Infidelity cases are among the most emotionally challenging, which is why our detective agency places the utmost emphasis on absolute discretion. Determining marital infidelity is accomplished through carefully planned observation and verification of the suspect’s activities. Our goal is to provide hard evidence (photos, videos, travel reports) that will dispel the client’s doubts or serve as evidence in divorce proceedings. We operate in a stealthy manner, ensuring that the information-gathering process remains undetected, which is crucial to the success of the operation.
What does a people search service include and what are the chances of success?
Searching for missing persons is one of our key specialties. We help locate family members, debtors, witnesses, and people with whom we lost contact years ago. We utilize extensive information resources, archival research, and advanced digital tools to achieve this. The chances of success are very high because we combine traditional intelligence methods with the analysis of the digital footprints that most people leave online. Whether the search is in Poland or other EU countries, we work systematically until the current location of the missing person is determined.
What is OSINT and how does a TSCM audit and wiretap detection protect my company?
OSINT (Open Source Intelligence) is advanced information gathering from open digital sources. Our detective agency uses OSINT to verify individuals and companies and conduct digital investigations. A TSCM audit, on the other hand, is a technical security check of premises. It involves the professional detection of wiretaps, hidden cameras, and other surveillance devices. In the age of industrial espionage, regular TSCM audits are essential for company boards, law firms, and public figures to ensure that their business and private secrets are not being leaked via illicit devices.
