Context
The French High Audit Authority (H2A), successor to the High Council of Statutory Auditors (H3C) since 1 January 2024, is the regulatory authority for statutory auditors and for professionals certifying companies' sustainability reports in France.
The legacy infrastructure, mostly based on Microsoft environments, lacked supervision and standardisation. The need was for a full infrastructure audit, improved security and performance, and the start of an IS-wide modernisation.
