Inevitably, large businesses will collect all kinds of sensitive data. Often, that’s personal identifiable data (PII) of their customers and employees, or other information that only a select number of users should get access to. But as the amount of data that large businesses collect increases, manual data discovery and classification can’t scale anymore. With Automatic DPL [Data Loss Prevention], Google recently launched a tool that helps its BigQuery users discover and classify sensitive data in their data warehouse and set access policies based on those discoveries. Automatic DLP was previously in public preview and is now generally available.

“One of the challenges that we see a lot of our customers facing is really around understanding their data so they can better protect it, preserve the privacy of PII for their customers, meet compliance, or just better govern their data,” Scott Ellis, Google Cloud’s product manager for this service, told me. “We really feel that one of the challenges that they face is really just that initial awareness or visibility into their data.”
