Hey ^^
I would also like to say something else.
You can really find a variety of information, you can also turn to companies that can advise you in this regard. So you just play it safe.
What I can also recommend is that you should attach great importance to the security of the cloud and data.
I also looked into the subject and found the Hamburg Pentest. Is Dr. Ewan Fleischmann - he's really got it.
IT security is checked there, from the point of view of hackers and attackers. In this way, gaps can be identified and eliminated.
I can recommend you too.
