This is a general question regarding the security of Confluence. We already use Confluence extensively for both internal projects as well as for sharing general documents and information with customers. Now one of our teams would like to use it for securely transmitting very sensitive documents with a user physically located outside of the company LAN. Our Confluence instance is already accessible outside of the LAN (since we share info with customers). We keep Confluence up-to-date and keep the server it is located on firewalled off so that only what needs to get through can get through. However, some of our management team has expressed some concerns about the security of Confluence. Is Confluence generally considered secure enough for sharing very sensitive documents? Are there any additional steps we should take before sharing those documents? Does anyone have any example use cases of companies doing anything similar?
