Cantonal specifics

Valais, a canton out of the ordinary.

Valais requires specific field expertise — here are the elements that distinguish Valais missions.

01

Rural and mountain surveillance

A large part of the canton is mountainous, with enclaved villages and sometimes unique access routes. Our investigators are trained in discreet surveillance in this type of environment — where a foreign car is immediately noticed. Suitable unmarked vehicles, systematic prior reconnaissance, selection of favourable time windows.

02

Seasonal economy

Alpine hospitality, restaurants and construction are dominant sectors in Valais. Sick-leave verifications are particularly frequent in high season (December-April in resorts, July-August in the valley). We adapt our method to the operational constraints of these sectors.

03

Cross-border missions

Valais shares borders with France (Chamonix, Évian), Italy (Aosta, Domodossola) and the canton of Vaud. Several files require coordination with partners across the border — always in strict compliance with Swiss law for the Swiss portion of the investigation.

04

Premium tourist resorts

Verbier, Crans-Montana, Zermatt and Saas-Fee host a wealthy international clientele. Asset files, solvency checks and security of premium real estate are recurring. We regularly coordinate with private concierges and local family offices for these missions.

Why us

Private investigator in Valais: police rigour, field knowledge.

Valais requires a specific approach — heightened village discretion, seasonal expertise, sometimes French-German bilingualism for Upper Valais. Our team masters these dimensions. Eric and Haris personally coordinate each Valais mission. Transparent travel costs (CHF 0.70/km from Chailly/Montreux), written quote before execution, report admissible before Valais jurisdictions.
