Our story

From police service to private investigation.

« We chose to leave the uniform. Not the method. »

Eric & Haris, founders

After years within the City of Lausanne Police Corps, interventions, emergencies, public order, municipal investigations, Eric and Haris reached the same conclusion: the private sector needed investigators trained in evidence, procedure and Swiss legal frameworks.

They founded Duo Guardians in 2024 to offer individuals, companies, lawyers and insurers an investigation level comparable to what they learned in the police, adapted to the private sphere — lawful and admissible.

Today, their combined experience, over 18 years in police and municipal investigation work in the canton of Vaud, applies to civil, commercial and personal cases. With the same standards.

III

Total discretion
