Systems and methods for improving access to and control of secure content. To prevent undesired data sharing/access (e.g., prohibited downloads, 4th, 5th-party sharing), access rules can be assigned to documents upon creation. These access rules specify the operations that can be performed to a document, who can perform those operations, and when those documents can be accessed to perform the operations. For each document, a separate container instance may be generated which can store the document comprising the private data. Each authorized user may be provided with their own container instance. Unique cryptographic keys may be generated for each container instance to allow those authorized users to securely connect to their respective container instances. This additional layer of protection (i.e., access rules linked to documents and unique keys for each document/client) allows for granular monitoring of the private data to prevent prohibited access attempts.
