Data that stays out of public AI tools

• A client's financial statements before publication: only inside the firm's corporate environment
• Client names, counterparties and amounts from ledgers: into a service as codes
• Audit working papers: confidential by audit law
• Personal data of the client's employees from payroll: anonymize it
• Conclusions about fraud and suspicions: never discussed with public assistants
