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.

Creates robust rules for communication and data security, boosting compliance measures
I was talking with some engineer from Microsoft about how we can audit our web page. They create or add to Microsoft Purview Communication Compliance that part, the Layer seven of the OSI model, to check the application and maintain a good practice of coding. I've tried the web page part, and it works great. However, monitoring and compliance for web applications could be improved.

Quotes from Members

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

Pros

"The most valuable feature of Microsoft Defender for Office 365 is its spam filter."
"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 has a feature to protect each and every attachment. Even if it's an encrypted attachment, it will check for any potential threats."
"My experience deploying Microsoft Defender for Office 365 was seamless."
"It has significantly decreased my time to detection and response."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"Defender helps us prioritize threats across our organization."
"There are several features that I consider valuable."
"Microsoft Purview Communication Compliance helps with extra collaboration and ensures communication is within the framework."
"Customer support is excellent."
"The features I appreciate the most in Microsoft Purview Communication Compliance include the ability to build cases, give them dates, and find them based on the notes that I left behind."
"The time it saves is very useful."
 

Cons

"The GUI is sometimes slow to fetch the device report and could be improved."
"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."
"About eight months ago, we started to measure the quantity of phishing and spam that we have been receiving, and it has been increasing a lot. That means that protection for our email is not as good as we were expecting."
"There is room for improvement in terms of reporting."
"I think that Microsoft Defender for Office 365 could be improved if it could use VirusTotal to compare the programs or anything that I download."
"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."
"Microsoft security solutions work as expected. They are constantly updating the solutions to make them better. At the same time, the changes can impact a customer's environment, and we need to adjust settings. Sometimes we aren't aware of the changes, and nothing is pushed from the backend automatically."
"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 Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"The product should incorporate more automation with the help of AI."
"Monitoring and compliance for web applications could be improved."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
 

Pricing and Cost Advice

"The pricing has become expensive."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"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 licensing, it's usually a yearly package for customers who are subscribed to Office 365, but they can also pay on a monthly basis."
"The product is expensive."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"It's a user-base subscription."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
