Hi,
Your question is more to use an online service vs. offline tools / functionality.....
The EOP uses a cloud based gateway, that means there should not be any change in your local environment...
The flow is, that a mail is first routed to the cloud gateway and from there to your on Premise Exchange server.
The management happens directly on the cloud server...
The advantage: You do not need to install any software nor to take care of the updates and mechanism of this service. Also there is no additional traffic, mails are just rerouted.
The disadvantage is, that an external service provider is between the sender and recipient, and this may result in some delays, as the mail goes first to the EOP provider, is scanned there and then routed to you....
Also a question of confidence...
Beside Microsoft, you find a lot of other service provider working in a similar way.
The second option is to use the built in functionality of exchange. And Exchange Edge in a DMZ can do the job before your internal exchange is touched. Additionally you need a virus protection solution beside Edge. Configuration needs some knowledge about PowerShell, for most of the functionality there is no user interface.
There are also other on premise E-Mail protection solutions out. Either as a software on a server inside the DMZ, which acts as SMTP gateway with virus scan and spam protection and a more friendly user interface, or you can use an appliance what is doing the same.
Microsoft EOP is also working like an appliance, this "appliance" is just located on MS servers.
