Filiale vs. sussidiario
The Italian words filiale and sussidiario both relate to subsidiary companies, but they have subtle differences in usage and connotation.

L'azienda madre controlla direttamente tutte le sue filiali.

Sussidiario

L'azienda sussidiaria opera in modo autonomo rispetto alla società madre.
(The subsidiary company operates autonomously from the parent company.)

Summary
While both filiale and sussidiario refer to subsidiary companies, filiale often implies a closer, more direct relationship with the parent company, like a branch. Sussidiario suggests a more independent entity that plays a supporting role within a larger corporate structure.
