info 3-stage check: technical validation against ZUGFeRD and EN standards, then PDF↔XML comparison with visualization, plus optional AI+ context analysis from Mistral (Paris) for clear risk classification. Security & Compliance

Why? ZUGFeRD/Factur-X contains a PDF (what you see) plus embedded XML (the dataset). Your systems process the XML — that’s where manipulation or silent deviations can hide (IBAN, amounts, taxes). Canary makes it visible.

14 risk fields in a three-stage test: Validation → Comparison → AI+

Explanation: Comparison assesses direct PDF↔XML discrepancies; validation primarily checks standard/mandatory rules (e.g., EN 16931) and is only of limited significance in the case of an IBAN mismatch; AI+ adds context analysis.
