Which licenses do i need?

Hi John,

Thanks for your reply and the table which did show me i quoted the wrong license in my question, i have a E5 license instead of an A5 one. This gives me the ability to manage every device in my school i choose to add or onboard to use the correct terminology! My conundrum is i pay for Windows 10 license which includes the free defender anti virus which is great for all my devices. I pay for a single E5 license so i can manage multiple devices from a single management PC do i effectively get to manage my whole site with one E5 license or do i need to buy something else for each client i am remotely managing using the microsoft defender for endpoint that comes with the E5 license which i now use to manage 400 clients. I was paying Mcafee thousands of GBP per month now im paying MS a couple of pounds per month for a single E5 license which in my opinion gives me a better endpoint protection for a couple of GBP per month? I must be missing something here?

Hi there, I am new to Office 365, I work in health care.  I have assigned myself a e5 license then my other workers a e3.  Is this sufficient protection for HIPAA?
