Strategic Intelligence Retainer Model
At DET.GROUP, we deliver investigative and intelligence services through a strategic long-term retainer structure. This model is designed for clients who require consistent, discreet, and legally compliant access to high-level intelligence capabilities, operational preparedness, and covert support in mitigating internal and external threats.
We operate as an embedded investigative asset within the client’s operational environment, capable of executing corporate due diligence, discreet surveillance, executive profiling, strategic vetting, and continuous mapping of reputational, behavioral, and operational vulnerabilities across key stakeholders and jurisdictions. Our methodologies combine lawful open-source intelligence (OSINT), proprietary analytical platforms, and in-field observation conducted by licensed investigators and intelligence operatives.
All activities are performed exclusively under covert protocols, ensuring that client identity, intent, and objectives remain protected at every stage. We deliberately avoid any form of public branding and do not reference our investigative role in any external documentation. Each client is assigned a dedicated operational team functioning under strict confidentiality protocols, supported by tailored technical and logistical infrastructure.
Billing Architecture and Cover Structures
Given the sensitive nature of the work, billing is structured through a legally distinct cover entity — a company formally unrelated to the private investigations or security sector. This design minimizes reputational exposure and prevents scrutiny during internal audits or third-party compliance reviews.
Services are rendered under a monthly retainer. The contractual scope, operational capacity, and tools provided are clearly defined and adjusted as required by the client’s evolving risk landscape. This model eliminates the inefficiencies of ad-hoc procurement and ensures uninterrupted support, real-time response capabilities, and continuous intelligence monitoring — without administrative delays or renegotiation.
Technology and Operational Infrastructure
The long-term retainer structure enables sustained investment in advanced investigative technologies not feasible under transactional models. These include proprietary OSINT platforms, metadata link analysis systems, secure data environments, encrypted communication protocols, mobile reconnaissance tools, and cross-jurisdictional location intelligence infrastructure. Select platforms incorporate AI-assisted pattern recognition and behavioral analytics.
These assets significantly reduce the reliance on prolonged physical surveillance and enhance both the speed and quality of intelligence delivery. In practical terms, this enables actionable insights within hours — not weeks — while maintaining lower operational risk and higher evidentiary integrity.
Access to these resources is reserved for long-term partners, as effective deployment requires contextual familiarity, operational continuity, and controlled integration into the client’s internal processes.
Operating Philosophy
Our intelligence operations are governed by three core tenets: discretion, analytical integrity, and strategic alignment with client objectives. Rather than offering reactive, one-time solutions, we emphasize ongoing cooperation, enabling situational awareness, early threat detection, and informed executive decision-making.
All investigative activities are conducted in full compliance with the legal frameworks applicable in the jurisdictions where we operate. Deliverables are structured to meet internal corporate standards and, where necessary, to satisfy legal admissibility requirements in regulatory or judicial proceedings.
Client Profile
This model is intended for corporate entities, legal advisors, family offices, and executive teams who regard security governance, informational advantage, and anticipatory risk management as integral to their strategic continuity. It is not suitable for one-time problem-solving, but rather for those seeking discreet, sustained control over sensitive scenarios through embedded intelligence capabilities.
