Featured Reviews

Cloud Solutions Architect at a tech services company with 201-500 employees
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.
Rastislav Maniak - PeerSpot reviewer
Partial Owner at Storage One
Archives emails and files, providing indexes for searching the archives
The tool has had some scalability issues, but now that it's offered as a cloud service, it's easier to manage. However, setting it up isn't as straightforward as it used to be, and there may be limitations with the support provided during setup and testing. Also, the quality of support has declined in the past year.

Quotes from Members

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

Pros

"The two main features that prove most beneficial for us are URL scanning and attachment scanning."
"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."
"The most valuable feature is the integration. It's a single console, so we don't have to switch around between multiple products. Another valuable feature is the ease of operations and maintenance."
"Microsoft Defender for Office 365 has improved my organization's security. It makes it easier to manage the infrastructure without the help of third-party applications."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"It has significantly decreased my time to detection and response."
"The feature of Microsoft Defender for Office 365 that I like the most is probably the email features specifically, because those are the ones that a typical end user will accidentally click on a link not knowing what it is, and it'll catch it, and then it'll feed it over to Defender and stop the attack from happening before it actually can."
"The tool streamlines data discovery processes for compliance by setting up a gateway to copy every incoming and outgoing email to the archive independently of the mailbox. This ensures that even if a user deletes their mailbox, the emails are still available in the archive, making it a compliant solution for monitoring all incoming and outgoing emails. Additionally, it offers the ability to place legal holds on important emails."
"The initial setup is pretty straightforward."
 

Cons

"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"From a development point of view, if I wanted to do development on my actual machine where Defender is, the organization can set certain policies or Defender makes that prohibitive."
"I am generally satisfied with how it currently is. If I could improve anything, I would reduce the cost."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"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."
"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"Microsoft Defender for Office 365 is not up to the mark in comparison with Wiz or Palo Alto."
"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."
"The tool has had some scalability issues, but now that it's offered as a cloud service, it's easier to manage. However, setting it up isn't as straightforward as it used to be, and there may be limitations with the support provided during setup and testing. Also, the quality of support has declined in the past year."
"Technical support could be better."
 

Pricing and Cost Advice

"The solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"Defender is a little bit more expensive as compared to others. We are in the manufacturing environment. So, we don't have a high budget for all of our endpoint devices. Its cost is a major concern for us."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"For licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"The license is expensive because the cost is based on the number of users."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The tool is expensive, and I rate its price as eight out of ten. It might not be very expensive. However, comparing it with something that's free or already included in the price is challenging, like the Office 365 archive mailbox. Previously, this was part of the subscription price. Now, it's an additional cost, typically covered by departments like legal or compliance rather than IT."
