Private detective in Essonne (91): Évry, Saclay
From the Saclay plateau, France’s « Silicon Valley », to the southern countryside: high tech and outer suburbs in one department.
Our detectives cover the whole Essonne: Évry-Courcouronnes (préfecture), Massy, Palaiseau, down to Étampes, with two dominant themes: protecting the know-how of Saclay’s tech companies, and classic outer-suburb family cases. Reports drafted for the Évry courts.
Two faces of the 91
To the north, the Saclay plateau (Paris-Saclay University, Polytechnique, CEA, tech firms of Massy and Palaiseau) generates innovation-protection cases: researchers leaving for competitors, breached clauses, partner due diligence, where our OSINT unit makes the difference. In the centre and south, Évry’s judicial hub, the RN20 retail corridor and a vast residential fabric produce the standard family and HR files of the outer suburbs.
Our most frequent assignments in the 91
- Unfair competition and know-how leaks: Saclay, Massy, Les Ulis
- Non-compete violations: tech engineers and sales people
