What protocol is used by Jamf Pro to send commands to devices?

The correct answer is Secure Socket Layer (SSL). Jamf Pro utilizes SSL to ensure secure communication between the server and devices. SSL encrypts the data being transferred, which helps protect sensitive information during transmission. This is particularly essential in a management solution like Jamf Pro, where sensitive device and user data is involved.

Using SSL not only ensures the integrity of the data but also authenticates the communicating parties, which is crucial for security in a networked environment. This level of encryption is vital in preventing unauthorized access and ensuring compliance with data protection regulations.

The other choices, while protocols used in various contexts, do not apply to the function of sending commands securely between Jamf Pro and the devices being managed. HTTP, for example, is a standard protocol for transferring hypertext but does not provide encryption. FTP is focused on file transfers without built-in security features. SMTP is specifically for sending emails, which does not align with device management commands.
