our company has decided to use QB Online however stills needs to understand whether the QBO Hosting provider complies with our IT security guidelines.
Could we therefore please understand who the QBO Hosting Provider is and whether they comply with standard Datacenter Guidelines such as ISO 27001?
Welcome to the Community page,
I would suggest you have a look at this link the developers would be able to tell you more about this.
Afaik, they are still partnering with AWS
If you have to open a new QBO account, make sure to click the Buy button to get the discounted price for up to a few months. If you purchase from the Trial account, you have to pay the regular rate.
