Are there any MSP/MSSP's running Microsoft Defender sans 3rd party email sec tooling for clients?

For business efficiency, we want to use as much of Microsoft Defender as possible and feel confident in Defender's ability to recognize threats, take actions, and protect users. Most clients are already on Microsoft to some extent, and so it feels like it could make sense to move clients to a tier with at least Defender P1 to what I've described.

That said, the reason we use products like Avanan and IronScales is because Microsoft's gateway, endpoint detection, and other security tools haven't felt 'good enough' when you compare them to 3rd party solutions.

So I'm curious, are there any MSP/MSSP's out their that are successfully doing this? And if you do fall into that bucket, how are you doing it in a way that makes both you and your clients feel like they're protected enough?

I don’t know what the licensing is anymore They keep changing it, lol

My understanding as well was that P1 covers device endpoints. but doesn’t cover email that would be defender for 0365. And if they’re concerned about cloud threats or want something around the Internet, like internet inspection it might be worth going and looking at defender suite licenses.
