If you’re looking at data masking tools, I recently was able to review the DataVeil solution. Quite simply, getting production data out of non-production environments is still a big issue. Solutions like DataVeil are designed to take production data and transform it in such a way that’s still usable, still maintains proper data distribution, and therefore looks enough like production data for our development requirements. The article linked are my thoughts on the product considering ease of use, flexibility, the ability to be deterministic with data changes, and its footprint in a development environment.
