Most enterprises use classification levels such as public, internal, confidential, and restricted. Some organizations also define sector-specific categories for regulated data types such as personal data, healthcare information, or payment card data that require specialized compliance controls.

Enterprises automate data classification using tools that apply machine learning, pattern recognition, and natural language processing to identify sensitive data. These tools can classify data during ingestion or discovery and scale across large data environments.
