Access Control: Access to documents can be controlled for different individuals or groups. A document management system leaves an audit trail of who viewed a document, when it was accessed, and how it may have been modified. 
 
Encryption: Files and documents may well be sitting securely on your server, but as soon as you send them to someone, they’re vulnerable to being intercepted by cybercriminals. DMS encryption protects data from falling into the wrong hands.
 
Version Control: Good version control beefs up security by keeping an audit trail of how files were changed, who saw those changes, and whether they have been approved.
 
Workflow Automation: A sound document management system will automatically route documents to their destination. This helps ensure that sensitive information isn’t accidentally sent to the wrong person.
