Insights

# Field notes & analysis from Exero Group investigators

Practical perspectives on investigations, fraud, intelligence and risk, written by the Exero Group team in Prague.

## Investigation insights for legal, insurance and corporate teams

The Exero Group blog is a practical resource for clients who need to understand when private investigation creates commercial, evidential or compliance value. We focus on issues that regularly arise in Prague, the Czech Republic and cross-border European matters: insurance fraud, due diligence, OSINT, surveillance, litigation support, background checks and lawful handling of personal data.

### What you will find here

Each article is written for real decision-making rather than abstract theory. We explain how to prepare an investigator's brief, which documents to collect before the first call, how to assess proportionality in surveillance, how to preserve chain of custody, and how fieldwork should align with GDPR, employment law and the expectations of courts or insurers. Where a topic requires caution, we also describe the limits: what a private investigator cannot lawfully do, when counsel should be involved, and how to reduce the risk that evidence is challenged later.

### Who the blog is for

The content is intended for lawyers, in-house counsel, insurance special investigation units, compliance managers, HR teams and business owners who need reliable information before instructing a sensitive matter. Articles combine local Czech context with a European perspective because many modern cases involve foreign shareholders, mobile employees, cross-border asset movement or digital traces that sit outside a single jurisdiction.

The aim is to help readers ask better questions, define a lawful scope of work and understand what kind of output will actually be useful. The blog is not a substitute for legal advice, but it is designed to make collaboration with a licensed investigation team clearer, more efficient and easier to defend.
