All the communications between the components of the product are SSL-encrypted
ManageEngine OS Deployer components communicate to each other using the Secure Sockets Layer (SSL) cryptographic protocol. Encryption starts on the first (earliest) stage of connection attempt, so all data transferred in the next steps (including data required for client authentication) is encrypted.
Once ManageEngine OS Deployer components are installed, encrypted communication between the components is enabled automatically. The deploy stream, being transferred via the communication protocol, is not encrypted.
Images or bootable components of ManageEngine OS Deployer can be protected with a password. For additional information, please see ManageEngine OS Deployer User Guide.
