We use it to encrypt our backups for Disaster Recovery purposes, which we believe will protect us from Quantum attacks down into future time periods (whereas symmetric encryption only protects you today).
It's relatively easy install & config but I think they could improve their support documentation as its not always clear what each setting does or how things interact with one another - some parts are buried deep in settings files that don't have descriptive names so can be difficult figuring out where something should go if using multiple servers etc.. Have been able set up 3 levels now without issue by tweaking configuration file parameters rather than doing trial runs via Cloud / On Premise environments though do give those tests first! Protecting data at rest across different platforms like laptops vs cloud backends has never really had this level security until recently when these new "Post Q" technologies came along.
