Ideally a free open source solution that can somehow be used to store versioned file types that are accessible within Confluence.
My goal is to use Confluence as a Knowledge Base with links to the Document Management system content which gives granular access control to in a similar way to Confluence's Spaces.
I need to satisfy ISO 27001,which is something that I don't think Confluence supports because of the way it natively stores attachments.
Thanks for reading.
