The solution seems to be very good at iterating on past editions and continues to improve itself. I don't know if it's truly lacking everything.

It would be great if it was a bit better at protecting from the endpoints.

The solution's technical support is slow and unresponsive. You need to book time in order to get support.

They're making improvements all the time but I'd like to see visibility into the spam emails so you can easily see them directly on the dashboard. 

They should allow copier release without having to create email accounts.

I've run into situations, especially when I'm using Office 365; if we're actually using copiers to send emails (of course you'd barely actually have to set up an email account, you just set it off to relay). If your exchange environment is only set to accept email from Sophos Email servers, those messages will never get delivered. Sophos flags them as spam and kills them even before they get there.

The security of the solution could improve.

Sophos Email can improve security. We would like more security for our customers.
