Back to original languageAbout Arnaud
IAM/IGA Consultant specialized in identity governance, access control, and regulatory compliance.
I focus on three concrete areas:
— Reducing the attack surface related to identities:
detection of illegitimate accounts, removal of excessive access, confinement of privileges.
— Ensuring the reliability of the account lifecycle (Joiner / Mover / Leaver):
HR ↔ IT reconciliation, discrepancy remediation, control automation.
— Production of actionable evidence: scored reports, timestamped logs, regulatory mappings (ISO 27001, DORA, FINMA, CSSF) directly usable by audit teams.
Environments: Active Directory, Microsoft Entra ID, hybrid AD/Entra ID, Azure AD Connect, Conditional Access / Zero Trust.
Automation: Advanced PowerShell — 33+ audit, remediation, and recertification scripts (6 public GitHub repos).
Field Experience: migration of 300+ AD identities → Entra ID, access review campaigns, RBAC enforcement, sealing audit reports (SHA-256, RFC 3161).
Immediately available Geneva (CH) Paris / Île-de-France / remote work.
