Case Study: VINCI Energies achieves continuous Active Directory security and seamless acquisition integration with Tenable Networks' Identity Exposure

How Vinci Energies Achieved Strong Security Parameters On Its Ever-evolving Active Directory Infrastructures

VINCI Energies, a global leader in digital transformation and energy transition operating in 52 countries with over 64,000 employees, faced growing complexity in its Active Directory (AD) estate after acquiring 30+ companies. Those rapid integrations increased misconfigurations and illegitimate access risks across dispersed teams, and VINCI needed a way to streamline onboarding of new entities without degrading its strong AD security posture.

Tenable Identity Exposure was deployed in 14 days using a remote-enclave, agentless architecture with only two part‑time VINCI staff, delivering web dashboards, real‑time analyses and instant security assessments to vet new organizations before connection. The solution enabled flawless company integrations, continuous global AD risk monitoring and automated, in‑context remediation—protecting ~85,000 accounts, running 16 million virtual analyses per hour and surfacing intelligence on 50+ threats while eliminating the need for individual audits.
