There are several features that I consider valuable. These include anti-malware and anti-phishing capabilities, along with certain remediation abilities for addressing issues once identified. Moreover, the system allows for easy reporting of problems. In the event of a phishing attack, we can conveniently initiate a comprehensive search to identify all related elements of the campaign and remove them from users' mailboxes. Additionally, the platform offers anti-spoofing measures targeting well-known high-value targets. This proactive approach helps in mitigating business email compromise by designating our high-value personnel. Consequently, any communication purporting to originate from these individuals undergoes a more rigorous verification process to ascertain its authenticity and whether it genuinely stems from a valid account associated with the respective individual.

I work in my company's IT department, so I use all of the products under Office 365 daily, including Microsoft Word, Microsoft PowerPoint, Microsoft Teams, and all the other components in the product. My company can't make it through a day or go by without using the products offered under Office 365. Some of our manufacturing workers may use Office 365 a lot less, but it is still necessary for things like Microsoft Outlook and Exchange. I found Microsoft Teams to be the most valuable feature of the solution, along with all of the products and features offered under Office 365. My organization has remote workers, and we can't run the company without meetings organized with the help of Microsoft Teams.

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.

Integration with external SaaS platforms and other Microsoft tools, such as PowerPoint and email, could be enhanced. Some users have expressed frustration with the changing licensing model and the need to pay for storage separately.
