Offsite confidential data storage?

["Saverio M." <saverio.pub () inbox com>]

In my company we'd like to store offsite a copy of a private key we use
for protecting confidential data.

Ideally, the company should be:
- software oriented (there are similar services for putting documents in
boxes, but it's not the case)
- the storage should be disconnected from the internet
- to retrieve the data some kind of human verification
(challenge-response, solve P = NP, et similia)
- resident in UK/IE

Is there some company that provides this service, or something similar?
Are there better (safer/more efficient) solutions?

Thanks,
Saverio
