Can tab visibility be used as the only method to prevent security permissions?

Tab visibility alone should not be relied upon as the only method for preventing security permissions because it does not provide comprehensive security controls. Tab visibility simply determines whether a user can see a tab in the user interface; however, this does not restrict access to the underlying data or records associated with that tab.

Users may still have the ability to access the data if permissions at the record level or other security settings allow it. Proper security measures must include a combination of role-based permissions, sharing rules, and other security features to ensure that sensitive data is adequately protected. Implementing a multi-layered security strategy ensures that users have the appropriate level of access while safeguarding against unauthorized access to data. Thus, while tab visibility can contribute to the user experience by hiding unnecessary tabs, it is insufficient on its own for data protection.
