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.

Provides clear visibility into our entire information estate, reduces our time to action, and saves us time
The integration across Azure is straightforward. Microsoft Purview Data Lifecycle Management has been a game-changer for our data governance. We now have clear visibility into our entire information estate, allowing us to pinpoint data location and implement effective classification. Even though real-time compliance isn't a current need, Microsoft Purview Data Lifecycle Management offers that capability for future requirements. Purview Data Lifecycle Management has reduced our time to action – since we previously lacked such a tool, it's effectively cut our response time in half. Purview Data Lifecycle Management has saved us one working day per month.

Quotes from Members

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

Pros

"Overall, I would rate Microsoft Defender for Office 365 at a ten."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"We use Microsoft Defender for its ability to integrate with existing business technologies, which is beneficial for protecting business areas."
"The solution is very easy to use. All you have to do is to assign the license to the end-user and it's done. The customer will only have the feature activated, and the solution will monitor the emails to determine if they are a threat or not."
"It’s easy to handle integrations, and we don't need a lot of people in our IT team."
"I like its investigation capabilities, as that is what is most important to me. It is fairly simple with a user-friendly interface."
"The product's scalability is good."
"Purview's built-in functionality provides immediate access to reports, streamlining the entire process."
"The automatic data labeling is compelling, and we are investigating its use."
"The UI is the most valuable feature."
"The system is stable; I haven't encountered any worldwide stability issues unlike other office products."
 

Cons

"They have moved features from one console to another. Things have been moved around in the interface and it takes me time to find where certain features are."
"We need to be able to whitelist data at the backend."
"The phishing and spam filters could use some improvement."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
"Microsoft Defender for Office 365 could improve by giving customers information on techniques to prevent threats. For example, information about best practices on how to protect their own devices against hackers and scammers, such as educational information or training. This would help others have a better understanding of cyber security. Additionally, there can be more security features added."
"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."
"There's room for improvement regarding the time frame for retrieving emails."
"The UI needs to be more user-friendly."
"The time it takes to scan is one issue; when we raise high-volume issues and tickets related to scanning failures, it relates to permission errors, which are technical challenges."
"Microsoft's Purview Data Lifecycle Management preview features can be unreliable, hindering their usefulness."
"Microsoft Purview Data Lifecycle Management can be challenging to implement due to its complexity and dense documentation, making it difficult to get started."
"Microsoft Purview Data Lifecycle Management can be challenging to implement due to its complexity and dense documentation, making it difficult to get started."
