Information about CMC Security
General Access Control
Does Cirrus Data have Access to My Data during Migration?
Does Cirrus Data have access to my data during migration? No. Cirrus Migrate Cloud is designed with security in mind that it is impossible for any volume data to be sent to Cirrus Data Cloud. By design no one from Cirrus Data will ever have access to your volumes at any stage of the CMC operations. During local migration, no data will ever leave your host. During remote migration, data can ONLY be transferred over the secure direct connection between the source and target serve
Are Data Securely Transferred During Migration?
Yes. For Remote Migration or Compute Migration where data is migrated from one server to another, all volumes are encrypted inflight during transfer by Transport Layer Security (TLS 1.2). Only the most secure cipher suite with perfect forward secrecy is used. The exact TLS configuration used is constantly updated automatically. For Local Migration, since the connectivity from host to new storage is the same connection to be used for production post-migration (and thus presumab
Can Cirrus Support Team see my projects?
If Remote Assistance is enabled on your project, authorized Support Representative from Cirrus Data can join your project. Support Representatives who joined your project will have a Support role that is equivalent to an Operator.
