"Powerful Email Security and Monitoring, but Support Needs Improvement"

4/5

What do you like best about Microsoft Defender for Office 365?

We use this as an email security tool and to monitor alerts and incidents. What I appreciate most about Defender for Office 365 is its ability to display all activities, even on a small server accessed from a device that has been onboarded to Defender. Its micro-level monitoring is impressive. Managing email security is straightforward thanks to the well-organized segmentation of tabs and lists. We rely on it almost daily to handle security breach incidents, which we can resolve quickly because of the robust features it offers. As a security administrator, I find it very effective. The implementation process was simple since it was deployed over the cloud. Additionally, we were able to integrate the tool with Splunk and the Argus portal without any difficulty. Review collected by and hosted on G2.com.

What do you dislike about Microsoft Defender for Office 365?

The most frustrating aspect of Defender is its support team. They are slow to provide resolutions and often fail to respond to emails, which means we have to go through the trouble of following up ourselves. I have dealt with support teams from other major companies, and this is an area where Microsoft really needs to improve. There is no hotline or direct number to quickly reach the Microsoft TAC, which makes the process even more difficult. While all the other features are excellent, my main suggestion is to enhance the quality of customer support. Review collected by and hosted on G2.com.

What problems is Microsoft Defender for Office 365 solving and how is that benefiting you?

Our entire inbox is well protected thanks to the strong features this software offers, including quarantine and ZAP. The tool provides both pre-disaster and post-disaster solutions, allowing us to address any issues whenever they arise. It is highly responsive and reliable, and unlike many other tools on the market, it has never experienced downtime. Review collected by and hosted on G2.com.
