A visualization mod is a visualization that has been developed by someone else than Spotfire, and an action mod contains one or more scripts that you can trigger from a visualization or on a property change. You might see the question of whether you trust the mod when trying to add a new visualization or action mod to your analysis.
For security reasons, the Review mod dialog is shown if you try to add a mod that has not been trusted before. If you have the appropriate permissions, you can make the decision to trust the mod yourself.
Note: It is important to only trust items that you are certain come from a reliable source. Read more about trust and security in Manage Trust.
If you decide to trust the signer, instead of the specific mod, then all future mods or new versions of a mod from that signer will automatically be trusted.
You can change your trust settings at any time. See Manage Trust for more information.
