Multisig Setup - Pruned Bitcoin Core on Computer vs. Dedicated Hardware
Both a full Bitcoin and pruned node can be run from Bitcoin Core with the same level of security.
Pruned nodes have the following differences:

Does not keep the full blockchain on disk
Size limit is defined by the user
Will discard unnecessary block data as it synchronizes

As a user on the Bitcoin Talk forum explains, most &quot;dedicated hardware&quot; Bitcoin Nodes are software wrappers around Bitcoin Core which may be less secure than running Bitcoin Core directly.
