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.

Automatically protects any files placed within a designated folder, simplifying data protection and ensure continuous data control
The hot folder feature is the most valuable feature of Seclore for safeguarding communications. For example, if an unauthorized user gets access to a file, you can remove their access even if they've forwarded it to someone else. The hot folder feature creates a parent folder that automatically protects any files placed within it. Additionally, when policies are created for third-party applications, files downloaded from them are automatically protected. For instance, pharmaceutical companies generate many files from third-party applications, and Seclore can automatically protect them.

Quotes from Members

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

Pros

"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"The product's scalability is good."
"The technical support is good and quick to resolve issues."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"The ability to respond to threats if very important."
"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"The hot folder feature is the most valuable feature of Seclore for safeguarding communications. For example, if an unauthorized user gets access to a file, you can remove their access even if they've forwarded it to someone else."
 

Cons

"The GUI is sometimes slow to fetch the device report and could be improved."
"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."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"The only thing they should improve is the licensing model. They should stop changing it. A year ago, the five features I mentioned were included in one product. Now, three of them are bundled into one product, and you have to pay extra for the other two. I don't mind paying extra, but I don't want them to change it every year or every six months. I need to know what I'm looking at and not worry about it next year."
"Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published."
"Configuration requires going to a lot of places rather than just accessing one tab."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"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."
"In future releases, I would like to see new features or more connectors for specific applications."
 

Pricing and Cost Advice

"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The product is expensive."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"The product is very expensive."
"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."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
"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."
