Do you know if it's possible to use ePO on a disconnected network? If so is there any documentation around how it's supported, how to update signatures offline etc?
I need to put ePO on an air gapped network but still need to be able to manage the systems down there.
Yes, this arrangement is more common than you think
ePO can function quite happily in such an environment - the only real chore is keeping it updated, for which you would need to download the ePO DAT package each day on a machine with external access, transport the file across the airgap and manually check it in as a product. Otherwise it's pretty much the same.
