"Fortinet FortiMail's most valuable features are antispam, antivirus, database, and data loss prevention (DLP)."

"The technical support is good and quick to resolve issues."
"It also gives the vulnerability status according to the versions you have selected. Let's say you have Google Chrome. It mentions the versions it has, and it updates. Within two hours of an update, it is reflected in the dashboard. That's really nice to have."
"There are several features that I consider valuable."
"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"Safe attachments, safe links, policies, and the ability to protect from zero-day threats are the most valuable features."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."

"Fortinet FortiMail's pricing could be improved."

"The solution doesn't scale easily."
"I don't know if it is possible, but I would like to see Artificial Intelligence and machine learning introduced."
"The XDR dashboard has room for improvement."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"Microsoft Defender for Office 365 should be more proactive."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"We need to be able to whitelist data at the backend."
"They can improve their security in a way where a customer can know if all their attachments are safe or not to open through a report. The solution does its job perfectly, but it never reports to the customer whether those attachments have been stopped before or not."
"In some situations, it has not been able to pick impersonated emails having no attachments. Technical support definitely has a scope for improvement."
"Microsoft Defender for Office 365 should improve the troubleshooting tools. It's unclear whether the device is blocked at the firewall level or at the device itself. The granularity needed for troubleshooting is currently lacking. From my perspective, Microsoft should address this issue to benefit many users who likely share the same sentiment."
