Various computer-implemented methods for securing data of replicated volumes are disclosed. In one example, an exemplary method for performing such a task may include: 1) identifying a set of plexes of a replicated volume, 2) identifying, within the set of plexes, at least one non-trusted plex, 3) intercepting data to be replicated to the non-trusted plex, 4) encrypting the data to be replicated to the non-trusted plex, and then 5) writing the encrypted data to the non-trusted plex. Various other methods, systems, and computer-readable media are also disclosed.
