How does Microsoft Information Protection facilitate secure external sharing?

Microsoft Information Protection enhances secure external sharing primarily by applying protective measures such as encryption and permissions to shared content. This ensures that sensitive information remains protected even when it is sent outside the organization. By utilizing these measures, organizations can control who has access to the information, what they can do with it, and how long they can access it.

The encryption helps to protect the content from unauthorized access, while permissions allow the data owner to dictate specific rights for external users, such as whether they can edit, print, or share the content further. This comprehensive approach facilitates safe collaboration with external partners while maintaining the integrity and confidentiality of critical data.

The other options, while they may contribute to security in different contexts, do not specifically describe how Microsoft Information Protection is designed to manage and secure shared content effectively in the realm of external sharing.
