Atlassian’s tools Jira and Confluence are being used by companies worldwide with many use cases. Some use it for internal purposes only, to plan projects, process campaigns and create content, other use it for customer requests, bookings etc.
While being used internally as well as externally, personal data is being stored at all times. Either from employees or customers.
A practical example in healthcare:
A customer has a request concerning his health insurance. He sends in an e-mail. In this e-mail he mentions his birthday, his insurance number and attaches a medical record by a doctor. This e-mail is used inside the insurance, to create a Jira ticket, which customer service is taking care of. The employee is able to access the database with all medical records and payments from this customer.
As you can see, a simple e-mail in healthcare can contain sensitive data from a patient. Breaches could lead to immense damage. This is why acts like HIPAA were passed.
