Improves threat visibility and response while reducing manual tasks and training users against phishing
I appreciate the attack simulation feature whereby I get to train users and educate them on how to identify phishing emails and spam emails, as well as the anti-spam protection. It gives me visibility into my threat environment and threat landscape to ensure that I am one step ahead of any likelihood of threats within my environment. I get to detect it and respond, so the threat intelligence is very effective. Microsoft security solutions save my time. It saves money because once I protect my environment, I don't lose money. It has decreased my detection time and my time to respond.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The risk level notifications are most valuable. We get to know what kind of intrusion or attack is there, and we can fix a problem on time."
"The email protection is excellent, especially in terms of anti-phishing policies."
"The most valuable feature is the integration; it's a single console, so we don't have to switch around between multiple products, and another valuable feature is the ease of operations and maintenance."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"The deployment capability is a great feature, and we're able to activate this feature throughout France with a click."
"Defender helps us prioritize threats across our organization."
"The coolest feature of Microsoft Defender for Office 365 is its ability to look for phishing emails."
"IP tracing is the most valuable feature."
 

Cons

"We need to be able to whitelist data at the backend."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"Configuration at the mid-level could be improved for the support team."
"One area for improvement is support, in terms of being able to reach them and, especially, technical support for configuration."
"Several simulation options are available within 365, and the phishing simulation could be better."
"In one of the reports I can get the exact place where a vulnerable file resides. But for that, I need to explicitly go into the device and check. If they could include that file part in the report, without my having to go to the device itself, that would help."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"The technical support needs improvement."
