Data egress refers to the transfer of data from a computer or network to an external source, such as a user or another system.
Examples of data egress include:
- email messages,
- cloud uploads,
- file transfers to a portable drive,
- chat messages.
Data egress can be legitimate, is required by most businesses, and can include sending invoices to customers or design documents to vendors. It can also result in unintended data loss, such as when an employee moves sensitive data to a personal email account to work away from the corporate network.
