After installing the free Confluence app, simply add a macro onto your Confluence page of either Risk Matrix or Risk Table, depending on the information you wish to display.

To customise the risk information to be displayed, go to the Macro Settings to specify what and how you would like to see the information on the page.

For the Risk Matrix macro, you can choose the risk project from where the information is displayed, the matrices you would like to show (either Initial, Residual or both) and additional information about the risks like Risk ID numbers, names and descriptions of Risk Classes, Severity and Probability Levels.

For the Risk Table macro, you can choose the risk project from where the information is displayed, the number of risks per page and in case you would like to display only a set of risks, the exact JQL Filter for it.

You can now have your Risk Matrices displayed on your Confluence page with all the details about the Risk Classes, Severity and Probability Levels. You can further customise the page for any type of report that you need.

Now that you have your Risk Table on your Confluence page from the risk project of your choice, you can write necessary text around it for reporting as needed.
To be able to easily navigate in the table, the Risk ID and Summary columns have been frozen when scrolling to the right.
