Erfarenhet som gör skillnad

Emilio Musso CEO Musso

Mussos uppdrag är att stödja företag, organisationer och myndigheter med tillförlitlig information i situationer där säkerhet, affärsetik eller internkontroll ifrågasätts. Genom professionell spaning, strategisk analys och rättssäkra metoder hjälper vi våra uppdragsgivare att förebygga skada, upptäcka risker och agera med fakta som grund.

We believe in a society where access to accurate information makes a difference – not just for businesses, but for the people in them.

Misstanke om informationsläckage från nyckelperson

Background: A Swedish technology company suspected that a manager in the management team was sharing internal product information with a competitor. Action: SNI conducted discreet surveillance combined with digital analysis and interview work. Result: The suspicions were confirmed and documented in a legally sustainable report. The person was dismissed with immediate effect and the matter was reported to the police.

Privatperson

Otrohetsutredning

I ett nyligen avslutat uppdrag kontaktades vi av en klient som under en längre tid upplevt att något inte stämde i relationen. Arbetstider som förändrades, sena kvällar som inte gick att förklara och ett beteendemönster som successivt avvek från det normala. Vår roll var inte att bekräfta misstankar, utan att ta reda på vad som faktiskt pågick. Efter en noggrann planering genomförde vi diskret spaning i offentlig miljö under flera tillfällen. Observationerna dokumenterades löpande med tid, plats och sakliga iakttagelser. Ganska snabbt framträdde ett tydligt mönster som inte överensstämde med det som kommunicerats till klienten. Uppdraget avslutades med en strukturerad rapport där vi redovisade exakt vad som kunde konstateras, utan tolkningar eller värderingar. För klienten innebar det ett svårt besked, men också klarhet. I den här typen av ärenden är sanningen ibland tung, men ovissheten är nästan alltid värre.

Otillåten uthyrning av företagslägenhet

Background: A real estate company suspected that an employee was renting out the company's apartment privately via AirBnB. Action: Through observations, analysis of booking platforms and identity checks, we were able to verify the suspicions. Result: Unauthorized rental was proven and the apartment was repossessed. The company avoided significant financial and legal risk.

Our process

from request to completed intelligence report

01

Needs analysis & consulting

We begin each case with a confidential needs analysis. Together we review the background, objectives and relevant risks. We then present a strategic plan, scope and timeframe – without committing you to anything.

02

Intelligence gathering

Once the assignment is approved, we begin discreet information gathering. This may include reconnaissance, technical control, background analysis, interviews, or open source intelligence (OSINT). All methods are legally permissible and adapted to the nature of the assignment.

03

Analysis and verification

Collected material is reviewed and analyzed by experienced investigators. We verify facts, check the credibility of sources, and place the information in a context that is relevant to the client's decision or action.

04

Reporting & consulting

The results are compiled in a clear, structured and legally sustainable report. The report can be used internally, as a support in decision-making, or – in some cases – as a basis in legal proceedings. We also offer follow-up advice if necessary.
