This is the first post in a 3 posts series covering Multi-Tenant Dashboards created using Sophos Central API's. In this post we will use the Detections API to build a Multi-Tenant Detections Dashboard as shown in the screenshot above. 


While talking to partners and customers using the Enterprise Dashboard, I regularly ask for an option to easily check which tenant has how many detections without the need of going into the tenants individually.

With the introduction of the recently released Detection API for Sophos Central building a detections-based report or dashboard became an option.

Initially I started working on extracting the data from Sophos Central using the API. Instead of starting from scratch I used the framework/samples provided during the Sophos Central API Academy 2022 as basis. This allowed me to build a PowerShell script which exports detection counters to a CSV-file. This CSV-file can serve as a basis for any report you want to create yourself.

Next up was the dashboard. Because I wanted to make sure that the dashboard would work in combination with any webserver (and not have any complex requirements like a database server), I decided to use the CSV-file and that the complete logic for showing the dashboard should be handled by the browser itself. The webpage I created therefore regularly checks if the CSV-file was updated and then refreshes the contents of the page automatically.

In the next section you will find the used components and a short guide on how to set up your system. By following these steps, you will end with a dashboard which looks like the screenshot at the beginning of this post.


The steps below should guide you through setting up your own dashboard. You yourself are responsible for setting up the webserver on which the dashboard will be hosted, I will therefore also not provide instructions on how to set up the webserver, define possible access controls, etc.

  1. Create a Service Principal with the Service Principal ReadOnly role (other roles can be used as well but the ReadOnly role has the least privileges). How this is done is described in Gettings Started as a Partner respectively Getting Started as an Organization.

  2. Create a html file from the code block below in a directory served by your webserver. Due to security implications we cannot use the "script" html-tag when posting code, you therefore have to replace all "s#c#r#i#p#t" entries within the file "script" when you create your html-file.

  4. Now that everything is prepared, we are going to run our PowerShell script for the first time with the parameter -SaveCredentials. This parameter stores the credentials of our Service Principal in a JSON-file, we do this so that we do not have to enter these credentials every time we run the script, for example:

    C:\Dashboards\Get-Central-Detections.ps1 -SaveCredentials

    This will scan all tenants linked to your partner or organization account, during the scan it will display the tenant name and whether the number of detections could be retrieved successfully. Please note that a tenant must have a XDR or MDR license!

  5. From this point on you should call the PowerShell script without the -SaveCredentials parameter (unless your credentials are no longer valid, and you need to update them).

  6. For the next step we need to run the PowerShell script with the following parameters:
    -Export -Path <path where to store the detections.csv file> for example:

    C:\Dashboards\Get-Central-Detections.ps1 -Export C:\Dashboards\wwwroot

    If you now check the webpage in your browser, just remember that the detections.csv file need to be stored in the same directory, then you should see the dashboard populated with the data from the CSV-File.

  7. Now that we have verified that everything works the only thing left is to schedule the PowerShell script with the -Export parameter on a regular basis. Under Windows you could for example use the Windows Task Scheduler.

Note: on July 10, 2024 I uploaded a new script which supports a fallback method, that can be used in case the Detections/Counts API call, does not work. I prefer to use the Detections/Counts API call because I get my results with a single call. The workaround for this issue is to use the Detections API call (so get a list of all detections in the last 24 hours) and then calculate the totals myself, this method is slightly more "expensive" because it requires at least 3 API calls per tenant instead of a single one.

So if you see "An unexpected error occurred while processing the request" while running the script try running the script with the new -Fallback parameter. 

Update: as of July 12, 2024 the Detections/Counts API is working again, meaning that you do not need to use the Fallback method anymore. 

I hope that you found the information in this recommended read post useful. If you did then please klick the like button on the right.

If you have not done so I recommend that you have a look at the other two posts in this series as well: 

PS. The PowerShell script included in this post was used with PowerShell 5.1 on Windows and PowerShell 7.4 on Linux.

Detections/Counts works again, so no need to use the fallback method.
