We used POVA for a pharmacy chain while conducting forensic accounting consulting project for them. POVA changed in the last few years and now the product is very good. It does deep analysis of all the sale data and related audit trails and builds cases with easy to follow narrative and proof lines. It makes it very easy to triage and followup. It runs locally on the retained data we already had so there is no fear of data leak. After the analysis we just deleted the whole server instance. We keep in touch with them for complex cases or cases with too much data to manually review. Review collected by and hosted on G2.com.
We have not noticed anything. More online training and support would be useful. Review collected by and hosted on G2.com.
