LSA

The Leading Supervisory Authority (LSA) is the Supervisory Authority that a data controller selects when is established in more than one Member State. So if your company is based in the EU, your Supervisory Authority will be the Data Protection Authority of the Member State where your EU company is established (i.e. Ireland). If you are established in more than one Member State (i.e., Ireland and France), you can appoint the Irish Data Protection Authority as your LSA and inform the French Data Protection Authority about it.
