Technical Description and Importance
Managing sanctioned outbound cross-tenant organizations ensures users can only collaborate with approved external domains, reducing the risk of data exposure. By adding or removing these organizations, you control the scope of permissible data sharing while supporting necessary business operations. This process facilitates compliance with potential data-sharing and organizational standards while maintaining robust data security. Regular updates and reviews ensure that only trusted organizations remain in the sanctioned list, aligning collaboration with business needs and minimizing risks from unauthorized external entities.
