I have a pair of Unity that I will be setting up for replication between sites, the Unity has D@RE, and I read in the DOC:
DATA IN FLIGHT As discussed previously, the Unity Data at Rest Encryption feature encrypts and decrypts data as it passes the SAS controller level. Data is only protected when it is at REST, stored on the backend drives or the internal M.2 SATA device. Therefore, data in flight to external hosts is not protected by the Data at Rest Encryption feature as it travels throughout the network
Now, the question...
If the replication data is unencrypted (NAS share in this case), what are the options for encrypting that replication data in flight from protected site to recovery site?
