About EntraGUARD

Frédéric Perez
IAM Architect & Microsoft Security Expert

EntraGUARD came out of my work with large accounts. Auditing an Entra ID and Microsoft 365 tenant meant days of work, scripts scattered everywhere and a report to rebuild by hand: expensive in time, expensive in money, and results already out of date by the time anyone read them. EntraGUARD puts that capability within reach of any company, at a reasonable cost.

m365expertise is 20+ years of experience dedicated to securing Microsoft environments. As an IAM architect and security expert, I help organisations in Belgium, France and Luxembourg audit and harden their identities and their cloud.
