The price could be better. It'll also help if they can continuously update and upgrade the solution. Every day there's a new virus uploaded into the network, and we have to keep updating it to identify all these things.

What could be improved in Microsoft 365 Defender is its licensing, e.g. it should be more consolidated and would be good if it has some optimizations. Improving the alerts and notifications, in terms of adding more details, would also be good for this solution.
