We reference Gazzang as a partner for encryption at rest. Following their acquisition by Cloudera, they have stated that they will not be developing their solutions for non-Hadoop environments

We do have partnerships with other providers, including Vormetric and IBM - all are covered in our Security Ref Arch whitepaper (and will be subject to performance characterization in a forthcoming bootcamp project)

Can the docs be update to align with the Disk Encryption section of the whitepaper?:
