In almost every of our projects, we face the challenge of collaborating with customers. However, for data security reasons, we do not want to allow external users access to our instance. Nevertheless, we face the challenge of sharing data and work items across departments and working on them together with our customers.
We currently synchronize these instances with the Backbone Work Sync for Jira (Two Way Issue Sync) app from K15t, which works very well and basically meets our needs exactly.
How do you deal with such challenges? What are your experiences?
