Secure Fields adds new, security-enabled Custom Fields to your Jira.
Almost all Jira native custom field types have their secure equivalents including:
Secure Custom Field is very similar in operation to a built-in custom field, except that it enables permission assignment. It adds functionality that was (until now), available only for whole projects!
The configuration is based on managing Custom Field Permission Schemes, thanks to which you can administer who to add the selected permissions to.
With Custom Fields, all data access methods are secured. No one can fetch your data using API or exports.
