Dear Stefan,
I work for a Trimble Italian company, and in Italy the clients often request this information for security assessment compliance, GDPR, ISO and NIS2. You can find much of the information you requested at this link: https://trust.trimble.com/.
In my experience, by registering on the portal I mentioned, you can access many documents and reports containing the data you requested, and you can also ask questions directly to the people in charge.
I hope this was helpful!
Best regards,
A.
