Microsoft Defender for Office 365 scales transparently for us, as we grew from 1,000 users to 3,000 users, and we didn't notice much difference.
The scalability of Microsoft Intune is ten out of ten.
Ideally, we want to automatically segregate devices based on user properties like primary use, but currently, dynamic groups seem limited to device properties.
It supports organizations with 200 endpoints and those with more than 15,000 endpoints.

Room For Improvement

Microsoft Defender for Office 365 needs enhanced virus protection, compatibility, UI, integration, reporting, and cost transparency to improve user experience.
Microsoft Intune faces challenges in cross-platform support, deployment complexity, feature limitations, and integration, affecting user experience and adoption.
The main area for improvement is simplifying the implementation and rollout process.
Microsoft could improve by offering recommendations for domain spoofing attacks, especially scenarios where DNS records like SPF, DKIM, and DMARC are not properly published.
There is a different console for different things; I just want one consolidated console.
Features like unlocking devices sometimes fail, and the support offered for other operating systems is insufficient.
There are communication issues, so you might start working with a feature without knowing if it will be deprecated six months from now.
Many third-party companies offer single-pane-of-glass reporting that shows you what your update environment looks like, how your patch is doing, application status, etc., but Intune's reporting is not intuitive.
 

Setup Cost

Enterprise users find Microsoft Defender for Office 365 pricing complex but valuable due to integration with Office 365 features.
Microsoft Intune offers cost-effective, flexible licensing options, especially when bundled, providing significant savings compared to alternatives like VMware and IBM.
We've likely saved 30% of costs.
Money-wise, it is a part of the Office 365 suite, making it slightly more expensive compared to Trend Micro.
Microsoft is quite affordable with a lot of features available for any size organization.
Introductory professional services, like a fast-track service, were included with our E5 membership, and there have been no additional costs.
The Intune suite and add-ons, such as batch management and remote help, are costly.
It costs approximately forty euros per user per month.
 

Valuable Features

Microsoft Defender for Office 365 offers comprehensive security with real-time updates and automated threat response, enhancing multi-platform enterprise safety.
Microsoft Intune offers efficient device management, security, and integration with Microsoft services, enhancing productivity and data protection.
It ranks the threats and allows us to prioritize those hitting us the hardest, such as email threats.
It provides end-to-end visibility on email threats such as phishing, extending beyond Exchange Online Protection.
The value of the DLP feature is significant to us because we have internal data, sometimes sensitive, and the users may not always be aware of security and privacy, which might lead them to send out information mistakenly to external parties.
Intune excels in configuration and compliance management for Windows 10, ensuring devices receive timely updates and adhere to organizational standards.
Dynamic groups allow us to set conditions for automatic membership, eliminating the need for user intervention or manual review and ensuring a seamless workflow.
Windows Autopatch is the most valuable because it removes the burden of patch management.

Featured Reviews

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.

Enables management of multiple operating systems with a single license
The best feature is that it's a Microsoft product, so if anything goes wrong, we get quick support for anything required. Remote system functionality allows us to sit anywhere and take control of any device via remote management. We can enhance security for clients' laptops with built-in Microsoft Defender, which is available with the Microsoft Intune license. We use it for reporting purposes through endpoint analytics. When pushing scripting, there are two types available: remediation script and reservation script. Through endpoint analytics, you can push defender policies to clients. It helps with reporting, inventory updates, and monitoring tenant status health.
