Stops evolving threats and offers peace of mind
We use the solution for wireless scanning, reporting, and monitoring.  The product is not resource-intensive.  The tool's most valuable feature is virus scanning, which has saved us from malware and ransomware.  We need to be able to whitelist data at the backend.  I have been using the product…

Easy to deploy and user-friendly with simple dashboards
I'm also using Microsoft Defender. We've also used Proofpoint. Proofpoint has more granularity. It also offers different features. Exchange Online and Defender offer safe attachments and anti-malware. However, they just have one single option for features, and you check a box, and it enables one blanket policy. With Proofpoint, you can choose your options. Microsoft products are good and more user-friendly in general. They are just missing the granularity aspect. In Proofpoint, the tap and trap work very well, and it has some kind of monitoring as well for the tap and trap. When you're moving from Proofpoint to Microsoft, if you need to do a comparison and if you need to showcase to the customer all features are working as expected, some functionalities might be a little difficult for us to showcase. Maybe that dashboard will differ. It's a common dashboard that we have for Microsoft. Maybe Proofpoint has got more features, however, for use cases, it'll be a little difficult to demonstrate to the customer. We've moved to this solution since we were moving the majority of our products to Azure. We wanted to move to the cloud to reduce hardware costs and avoid having a separate server, which we do not need for Exchange.

Quotes from Members

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


"The product is not resource-intensive."
"The initial setup was easy."
"The most valuable feature is protection against malicious links, fishing, and impersonation. You can train people to be aware of these threats, but they're not always careful. When they're using their phones between meetings, they click on a link, and it's game over."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"Microsoft Defender for Office 365 is a stable solution."
"The benefit that stands out to me is the ability for multiple individuals to collaborate simultaneously within the same document. Additionally, there is the option to save the document directly in the integrated OneDrive or SharePoint."
"Defender for 365 is a comprehensive cloud-based solution. The value of the cloud is that you aren't alone. Threat intelligence and analytics are shared in the cloud. We don't have to find the solution alone. If you face an unknown threat with traditional solutions like Trend Micro and Symantec, you need to open a case and send your information to them to analyze forensically and identify the source of the attack."
"Does a thorough job of examining email and URLs for malicious content."
"Microsoft EOP's most valuable feature is a shared mailbox."
"With Microsoft Exchange Online Protection, if malware is attached to a mailer, it's very easy to go into the incident alert and find out what's happening with that identity and the mail."
"The pre-set policies and configuration analyzer are the most valuable features."
"It provides security to both on-premises and Azure infrastructures."
"It offers great security against malware and other threats."
"The scalability is pretty good; it does what it is supposed to do."
"The initial setup of Microsoft Exchange Online Protection was easy."
"The initial setup was easy. The configuration process is very straightforward."


"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."
"Several simulation options are available within 365, and the phishing simulation could be better."
"There is room for improvement in terms of reporting."
"The UI needs to be more user-friendly."
"It would be better if it were more scalable. It depends on the architecture, but we would like to make it more scalable for both data centers."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"There needs to be an improvement in integrating the product to work across multiple operating systems, and to have better support for non-Microsoft file types."
"Microsoft Defender for Office 365 should be more proactive."
"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"The solution needs to improve its backup."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"When you're using a Microsoft product solution, you can scale it, but if you're not, there are limitations."
"The tool's classification for bulk email is cumbersome."
"Microsoft has some training portals, but more could be developed."
"The biggest issue that I experience is that Microsoft keeps moving things around, and it's very inconsistent as to where you find the information when you're trying to work on different pieces."

"I know that the product is incredibly expensive."

"The solution is expensive but is backed by Microsoft's reputation."
