Diagnostic Cybersécurité 360° is a comprehensive cybersecurity assessment service offered by ACG Cybersecurity. It is designed to evaluate and address the security posture of organizations across five distinct intervention axes: 1. Infrastructure security 2. Application layer and data security 3. Endpoint security 4. Identity and access management (IAM) 5. Data-in-transit security The service follows a sequential and cyclical process structured around five operational phases: anticipation, prevention, protection, detection, and reaction. This lifecycle approach is intended to proactively address information security risks while accounting for evolving threat landscapes and regulatory requirements. The 360° methodology is derived from an analysis of regulatory frameworks cross-referenced with the operational security needs of businesses. It covers the full spectrum of an organization's security posture — from network-level concerns to data-level risks, including data exfiltration prevention in connected environments. The service is positioned as a curative security offering ("Sécurité curative"), targeting organizations seeking a structured, end-to-end diagnostic of their cybersecurity state. It uses proprietary tools developed internally by ACG Cybersecurity to perform assessments.
