Detective agency and Investigation Service



NSA offers comprehensive detective and investigative services. This investigation service is not limited to Austria. We work with international partners and can offer you worldwide service.

Operational Planning.

Every investigation starts with a personal interview where aims of investigation are set. Every step of the investigation is arranged with you personally using discrete and legal methods exclusively. All your information will be treated confidentially. The results of the investigation will be given to you alone.

Of course, this includes a detailed report with all findings and all evidence acceptable in court. NSA sees it as their task to detect and document all facts that are beneficial to you in their investigations. NSA has been working for years with law offices specialized in such issues. Upon request we provide a risk assessment and legal evaluation of the investigations desired.


If necessary for the investigation technological solutions can be offered such as mini-cameras or satellite tracking.
