Light and powerful solution design; useful to have
My impression is that the initial setup process is quite straightforward. If you know what you're using it for, the initial setup can be quite easy and the solution is not that hard to use. When it comes to the steps taken for the implementation, you would select the OS you're using and when the files are sent to the appliance you check, and in the appliance configuration, it must be like the visual governance environment. You must set up the OS you have so that appliance can scan or analyze your file. To maintain this solution, you must always have at least one all-around person tuning this solution.

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.

Quotes from Members

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

Pros

"The solution is very good because it catches a lot of threats in emails."
"You have access to a report as to what behaviors the example file entered in the registry."
"The solution extracts an attached file before reaching the user and notifies the user if there's something malicious in the attachment received along with an email."
"It is an easily scalable solution."
"The adapter is beneficial as it allows integration with various devices, not just Fortinet."
"The most valuable feature is the protection and the way it works, the technology is what I like the most."
"he solution's GUI is good."
"The GUI makes administration tasks straightforward."
"Microsoft Defender for Office 365 helps people to work remotely. It is a secure solution. We don't need to use our company's computers or get VPN connections to the networks. I can control how they share screens and what they send to the devices. It keeps our organizations confidential and sensitive information safe."
"The stability of Microsoft Defender for Office 365 is fantastic."
"Since we have started using the solution, there have been fewer compromises."
"Defender enables us to secure all 365-related activity from a single place. It gives us visibility into everything happening in Outlook, protecting us against phishing and other email-based threats. Defender helps us detect any suspicious behaviors."
"The basic features are okay and I'm satisfied with the Defender."
"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."
"Microsoft Defender for Office 365's most valuable features are safe attachments and safe links."
"It also gives me good visibility because, with Defender, I'm using a Microsoft product to defend Microsoft products. The integration was really seamless and I have wide visibility because it picks up almost everything. Literally, I can see almost every activity that happens, from the e-mail to the workstation itself."
 

Cons

"I don't know if it is viable to do an improvement like this. When there are passwords in the password-protected files, it can't scan them or do things like this. I don't know if an algorithm or something else could make it better. Nowadays, many legitimate office documents have passwords."
"It would be better if we could integrate FortiSandbox with endpoint security solutions."
"The area I would like this solution to be improved in is the integrations for Sandbox with AI and big data ML mechanisms. I think this would be a practical improvement."
"The main area of concern in Fortinet FortiSandbox is its detection capabilities."
"If updated, Fortinet FortiSandbox could cover other risks."
"Product could include a user interface and be made simpler for customers to configure."
"At least once a week we have a false alarm. This needs to be adjusted so that we get fewer of these occurrences."
"The use cases in Fortinet FortiSandbox are not good. It is difficult to upload a custom VM for Fortinet FortiSandbox. The integration of Fortinet FortiSandbox with other Fortinet or FortiGate firewalls is not good. VMs are already installed in the hardware and are working fine, but we tried to approve the custom VM many times but did not succeed."
"This product's effectiveness could be improved, in terms of detecting unwanted spam or even malware between the emails, compared to other products."
"I'd like some additional features any product can give me to protect our environment in a better way."
"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."
"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."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"One area for improvement is integration. For example, when it comes to external SaaS platforms, we were not able to get a lot of information on integrations with such apps for security and authentication."
"Too many false positives and lacks an accurate capability to detect malicious SharePoint sites."
"You should be able to deploy Defender for every subscription without the need to add servers."
 

Pricing and Cost Advice

"The solution is not expensive at all."
"The price of Fortinet FortiSandbox is not expensive."
"We are on an annual license to use the solution. We have an additional feature that is integrated with S5, which is working well."
"FortiSandbox is a subscription that can be purchased from Fortinet directly. Only using FortiSandbox as features purchased as a subscription in the cloud."
"The price is competitive."
"The price of Fortinet FortiSandbox is expensive."
"There are additional costs, which isn't included in the licensing fee."
"The solution is unavailable at a lower cost and can be difficult to deploy."
"The product is very expensive."
"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 solution could be better by simplifying the business model of their licensing. It was hard to figure out how to get the licensing done for the environment, initially."
"The pricing has become expensive."
"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."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
