Column-level security is a feature that is only available in the Enterprise or higher editions of Snowflake. This feature provides advanced data protection by allowing administrators to define security policies at the column level, ensuring that sensitive data is adequately protected. In contrast, features like SOC 2 type II certification, Multi-factor Authentication (MFA), and Object-level access control are available in lower editions or are common security practices. Therefore, the correct answer is Column-level security.
