Enhanced network security with adaptable integration and really good support
We use FortiSandbox for scanning files and images that pass through our networks. It integrates with different devices, such as five adapters and other Fortinet devices It is time-saving and more secure. It saves us from a lot of antivirus and anti-malware issues. The adapter is beneficial as it…

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 most valuable feature was the EDR, endpoint detection and response."
"The solution is easy to manage."
"The most valuable features of Fortinet FortiSandbox are the analysis options, artificial intelligence, and the many interfaces it provides."
"FortiSandbox helps us handle unknown threats. Every vendor is competing for who can detect an unknown threat the fastest. Fortinet is competitive in the market."
"he solution's GUI is good."
"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."
"The solution is very good because it catches a lot of threats in emails."
"The scanner office document as well as PDF are useful. The most valuable thing is that you can emulate different operating systems without having the danger of getting something infected. It emulates several operating systems, and as a result, you either get the file or you don't get the file."
"Microsoft Defender for Office 365's most valuable feature is its performance."
"The good part is that you don't have to configure it, which is very convenient."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Threat Explorer is an invaluable tool for me, and it plays a crucial role in helping me discern the origins of various email campaigns, pinpointing where they emanate from, and identifying the individuals within our organization who are affected."
"It gives us visibility into threats and, for endpoints, it helps us to prioritize threats. We used to have a lack of visibility, but now our time to detect and respond has decreased."
"At the moment we are satisfied with this product. It's a stable, scalable, and resilient solution for us."
"I would say that 90% of the spam and phishing attack emails get blocked right off the bat."
"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."
 

Cons

"If we can have more dashboards, it would be good."
"In general, maybe they are not updated to cover risks."
"In future releases, I would like to see more automation capabilities."
"The main area of concern in Fortinet FortiSandbox is its detection capabilities."
"It can be difficult if you need to use the Command Line Interface (CLI). It's much easier if you only have to deal with the GUI."
"Something that needs to improve, is the end-point protection."
"It would be better if it had support for Mac and Linux."
"For additional features, maybe a form of execution pain files in a non-virtual environment because it has threats that identify when it is being run in a virtual machine."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"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."
"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."
"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."
"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."
"We noticed that from time to time, Microsoft's stability does have problems. Sometimes the service goes up and down. Sometimes they change without prior notice."
"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."
"Sometimes, phishing emails manage to pass through the filter, so the system needs to enhance its phishing email detection capabilities."
 

Pricing and Cost Advice

"The solution is not expensive at all."
"The price of Fortinet FortiSandbox is expensive."
"Fortinet FortiSandbox is a nominally priced product, so I would not say that it is a very cheap tool."
"There is a license to use this solution."
"The price is competitive."
"The license for Fortinet FortiSandbox depends on the use case."
"Fortinet is more reasonable than Palo Alto."
"FortiSandbox is a subscription that can be purchased from Fortinet directly. Only using FortiSandbox as features purchased as a subscription in the cloud."
"The license is expensive because the cost is based on the number of users."
"Defender for 365 comes in various plans and licenses, along with other Microsoft security solutions. Purchasing this kind of package or security bundle gives good value for money, and that's what I recommend."
"For large enterprise organizations, they can definitely afford it, but for small and medium organizations, they might struggle to cover the expenses."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"It is much more expensive than using another solution because we have had to include some options and upgrade our license."
"The pricing is normal. Considering its popularity, it's not overpriced."
"While Microsoft Defender for Office 365 necessitates pricier E3 or E5 subscriptions, the extensive functionality offered by these licenses across various Microsoft products justifies the investment."
