Question about the security level of Unity Analytics's cloud environment

Not sure this is the right place to post, but I have a question about the security level of Unity Analytics’s cloud environment.

We are currently developing the app for our client and they require all cloud providers to meet their security standards. Their security standards are, for example, whether security patches are applied on a regular basis, or malware monitoring software is installed, etc. Is there a document describing what kind of security operations you are performing? I looked at the privacy policy and terms of use, but could not find them.

Anyone can help or anyone has a suggestion for the right place to ask?

I am looking for Unity’s equivalent of this kind of security document:

i guess need to contact support…

i’ve seen this post earlier, maybe can ask him too:
