Our promise

Sentinel Group has a proven track record of reliability, expertise, speed and discretion in every security sector, as well as many years of experience in highly sensitive areas. As a result, the target person or company usually never learns of any investigations, unless we are called as a witness in court to be questioned about our reports when they are introduced as evidence.


Experienced team from various governmental and non-governmental security structures

Since 2001

Your partner for all areas of security for more than 20 years

100% discretion

A highly discreet handling is a matter of course for us

Your international partner for all security areas

In direct cooperation with your corporate security, we implement protection mechanisms and processes that protect your business processes from digital and physical threats. Our extensive portfolio ranges from investigative activities (core business of the Austrian location) in almost all legal areas, compliance checks, in-depth due diligence, consulting and operational security services. Operational security services are mainly provided abroad, as the market for these services is relatively small in Austria.

As the risks threatening our companies are becoming increasingly complex, our long-standing cooperation with highly competent specialists in their specialised fields has proven its worth. We have joined forces with these partners to form a “Corporate Security Alliance”. This complementary approach gives us an above-average level of interdisciplinary expertise, enabling us to provide the 360° security service you need. Nevertheless, you always have one contact person for the entire operation to ensure that the project runs smoothly.

Our group of companies also includes the security company Sentinel Special Branch Pty ltd, Johannesburg, South Africa. This company, together with its subsidiaries, is involved in the training of security forces of governmental and non-governmental structures, as well as security services for high-security areas.
