What you're also going to need is an Office 365 backup solution from https://spinbackup.com/products/office-365-backup/, which helped me a lot with the security of my data.
Here's what I was able to do:
1. Store a separate copy of my critical data at AWS or GCP.
2. Protect my Admin account against hijacking.
3. Protect my Users against ransomware and data breach.
