DET.GROUP is a modern private investigation firm operating across selected European countries.
Our team consists of experienced investigators and specialists with professional backgrounds in intelligence, security, and related operational environments. We are among a limited number of private investigation firms with hands-on experience in extensive intelligence operations, complex field activities, and demanding cases requiring a high level of discretion, coordination, and operational expertise.
This experience fundamentally shapes the way we approach each assignment. Our work goes beyond standard private investigation services. We apply structured intelligence methodologies, analytical techniques, operational planning, and our own technological capabilities. This enables us to handle complex and long-term assignments that require a broader scope of activities, continuous information analysis, and a coordinated operational approach.
Our primary focus is long-term cooperation with corporate and institutional clients, providing comprehensive support in the fields of external intelligence, analysis, and operational activities. At the same time, we also handle individual cases for private clients.
DET.GROUP also operates its own IT and technology division. We develop and manufacture advanced technological solutions, software tools, and specialised equipment designed to expand our operational capabilities and support the effective work of our specialists in the field.
By combining experience from the security and intelligence environment with analytical expertise, operational capabilities, and in-house technological development, we are able to approach each assignment comprehensively.
