Service provider benefits from effective email security management and seeks enhanced customer support
Reporting could be one of the areas for improvement, as they could put more reporting into Microsoft Exchange Online Protection (EOP) natively rather than requiring additional licensing or connecting to other parts of the Microsoft suite, but it depends on the license you have. There aren't significant concerns with Microsoft Exchange Online Protection (EOP), as it depends on what customers expect; if they expect more features, then it depends on what Microsoft 365 license they have. The important thing is to ensure they are using all the security features they get with their licensing. The basic one is Microsoft Exchange Online Protection (EOP). While it's nice to have more functionality, that's available through other licensing programs with Microsoft. While we'd prefer more features, as a basic tool, it's fine, but more advanced features come with the add-ons from other parts of the Microsoft 365 licensing. One feature that could improve Microsoft Exchange Online Protection (EOP) is automated malware detection, where it actually analyzes the file offline in a sandbox to determine if it's safe, potentially reducing false positives.
