Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

Enhances email security and has a very simple and easy-to-use UI
Spam protection is the most valuable feature. We have implemented the tool to enhance our email security. It helps prevent phishing attacks. The anomaly detection capabilities are baked into the security platform. The product integrates wonderfully with Microsoft 365. It's built right on a cloud platform and works almost natively. The solution has a very simple and easy-to-use UI. The tool appears extremely powerful and has a good solid feature set. It catches things that are bad for my environment. The user interface is good the way it is. If the solution continues down that path, I see no problems with the way it is going. It feels like a mature product.

Facilitates creation of your own content-filtering policies with relative ease
* Ability to create message bypasses for groups and/or individuals. Meaning, you do not have to "whitelist" email domains or addresses when a specific bypass will do. * Personal Message Manager (PMM): It allows users to release or delete quarantined messages. Also, allows users to add people to a Trusted Senders list. * Ability to create your own content-filtering policies with relative ease.

Quotes from Members

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

"The most valuable aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"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."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"Defender is a SaaS platform, so it offers more flexibility. Managing the permissions is easier. The solution's automated detection and response features are scalable."

"Email inspection has saved many employees from spam attacks and viruses from unauthorized sources."
"A stable solution."
"Ability to create your own content-filtering policies with relative ease."
 

Cons

"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"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."
"We need a separate license and we don't know how to get the license that is required."
"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."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"The customer service team could come up with clear tutorials on how to use this platform to help new teams."
"It is very difficult to find the required documentation."
"It should also offer a quick backup in case any email is wrongly quarantined or deleted to ensure no data loss."
"Sometimes it seemed like the allow list wasn't working. I've created many allow list rules however, they still seem to be blocked; the same is true with the blocked list rules."
"Familiarization with performance for new teams may take a long time."
"The user experience must be improved."
"In Avanan, the email channel is one of the channels where data leakage happens, and they need to consider it from a DLP perspective."
"It should reduce the amount of time needed for thorough scanning."
"Malware needs improvement."
"FTP server and TRUST Manager functionality."
 

Pricing and Cost Advice

"The product is very expensive."
"Compared to other brands, Microsoft Defender for Office 365's pricing is competitive."

They know exactly how many users are using it, etc. We can tune the invoicing associated with how we are using the product so we can charge it back to the shows appropriately."
"Good pricing arrangement as an SaaS offering."
