Only allow to see cards, where you are a member

[Sebastian Vogt]

Hey together, we have some external service partners and would invite two of them to one of our Trello boards. But before we do that, we want to ensure that each service partner can only see Trello cards within the board, where the respective service partner is assigned as a member for the card. Is that possible? They should not see cards, where they are not assigned as a member of the cards?

Or is it mandatory to create a separate board for each service partner, because in each case, a member of the board can see every card within the board?

Maybe somebody can help me with that problem :)

The rule of thumb is that all members will be able to see details of any card when they have access to a board. Creating a board per partner is one way but you can also considering using Hipporello share card solution.
