External Tokenization

External Tokenization allows organizations to tokenize sensitive data before loading that data into Snowflake and dynamically detokenize data at query runtime using masking policies with External Functions.


External tokenization requires External Functions, which are included in the Snowflake Standard Edition, and you can use external functions with a tokenization provider.

However, if you choose to integrate your tokenization provider with Snowflake External Tokenization, you must upgrade to Enterprise Edition or higher.

To inquire about upgrading, please contact Snowflake Support.
