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.

Two-factor authentication and .ZIP format make large file transfers very secure
The most valuable feature is the ability to send a large file of 30 GB in size and more. In Outlook and other email applications, you cannot send files that are larger than 20 MB. But with Kiteworks, 30 GB is transferable by default and, with the proper approval, a file of up to 100 GB can be sent. It makes file transfer very easy and smooth. Also, only the .ZIP format is supported because it is a very secure mode of file transfer, and that is why it is recommended. It also has built-in antivirus, so if it detects any malware it will quarantine the file and it won't be delivered. This is really important to keep the service up and running in a proper and secure manner. With people working from home, the data needs to be checked to see what kind of data is being sent. It has a two-factor authentication mechanism. For example, if a person with a particular domain is using Kiteworks and sends a file to a party outside of his domain, that external party has to go through two-factor authentication. The receiver gets a link that takes them to the setup of a temporary account, which will be valid for three days. The recipient will also receive a customized password separately. Only after all these steps will they be able to access the file. That access is only available to a person with the mail ID to which the file was sent. In addition, admins can see who is sending sensitive content, what that content is, and to whom it is being sent, and can track emails. One week of good training will give a user complete knowledge for using the solution. The system is very easy to use. You just click on "Compose," attach a file, and send it. It's very easy compared to Outlook or Teams. It's quite simple, even for someone logging in for the first time. It is very smooth and easy to send files.

Has an easy implementation phase to deal with for users
I primarily use the product in our daily security operations since it is implemented in all of our company's systems and is used in our environment. Normally, email security tools like FireEye or Trellix help to protect ourselves from spam, malware, and other email-oriented threats. The tool is used extensively in our company's environment. It is more like a collaboration email security that is used in our company. Whether my company plans to increase the number of users of the product or not is something that depends on the growth of the organization. I recommend the product to those who plan to use it. The product is stable and reliable, considering the results my company gets out of it. When it comes to Trellix or FireEye Endpoint Security (HX), the tools offer antivirus as well as the modern real-time security feature, which is used to automate the detection and protection of the endpoints against all the security threats that are currently there in the industry. I don't see any challenges with the integration part of the product, but since a different team manages it, I don't have visibility into it. In terms of the value offered by the product, the solution does help our company protect data and the complete infrastructure. I rate the tool a nine out of ten.

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 aspect of Microsoft Defender for Office 365 is its ability to protect us from malware."
"The most valuable feature of Microsoft Defender for Office 365 is the ease of use."
"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."
"There are several features that I consider valuable."
"The email protection is excellent, especially in terms of anti-phishing policies."
"Since we have started using the solution, there have been fewer compromises."
"The good part is that you don't have to configure it, which is very convenient."
"The deployment capability is a great feature."
"The best part of this solution is that we can generate multiple reports about how the data is transferred and about user information or IP."
"We can see when people are sending things. We can definitely see who is sending to whom. From the administrative logs, we can see who is sending to an outside entity, and those logs are retained for quite a while."
"The solution removes the limitations with file attachment size that is found with regular email."
"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"I can identify from which region our users are uploading or downloading files."
"The top two features are the two-factor authentication, which is pretty good. It's easily understood by the users. And their API is rather robust. We have numerous integrations that work off the API."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"Trellix Collaboration Security is valued for being a stable and comprehensive solution that fulfills customer needs."
"FireEye Email Security helps us prevent spam and phishing emails and all other business-compromised email attacks."
"The product helps reduce the number of malicious emails reaching the user's inbox."
"The product protects my email."
"FireEye is good for malware depicting and security."
"Before installing, consider potential challenges with system performance, especially when integrating multiple tools, which could slow down performance."
"We can control this solution from the cloud and are able to access it from wherever we are."
"One of the most valuable features is the protection against vulnerabilities, particularly through virtual patching."
 

Cons

"Microsoft needs to broaden its global support presence by establishing teams of subject-matter experts in all regions."
"Configuring the default strategies and policies in Microsoft Defender for Cloud Apps generates a lot of noise and false positives."
"Microsoft Defender for Office 365's Mac functionality requires improvement to deliver the same level of protection found on Windows devices."
"The product must provide better malware detection."
"The changes to customer service, specifically the new model for support agreements, are not favorable."
"The certification training for Defender for 365 needs to be deeper and incorporate Sentinel. I took all the security courses except one, and Sentinel isn't included."
"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."
"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."
"I noticed the Kiteworks login UI is very basic, lacking customization. Allowing more HTML tags to add hyperlinks or user-friendly information on the home page would be very useful."
"File location could be improved."
"There is no offboarding process for end-users in Kiteworks. It's a manual process. There is no automated syncing with LDAP and checking to see if the account is still active. It's a manual process to get people out of here, which isn't the best way."
"I would like to see immediate releases of fixes because now it takes at least a week. If that time span can be reduced to one day or two days, that would be very helpful for users so that things are sorted and transactions work smoothly."
"Kiteworks could benefit from enhancing the proposal knowledge base section, specifically regarding the type of work involved. Currently, the knowledge base seems insufficiently dedicated to this topic, making it challenging for new users to access the relevant administrative law. Improving the visual aids and providing clearer explanations could alleviate this issue."
"Perhaps there could be a notification to users about their bandwidth or network packet loss."
"In my experience, their technical support can be a little slow."
"It would be nice if Kiteworks could provide a free version of the platform so that it could be used for a certain number of file transfers. We could be charged a fee if we exceeded the number of allotted file transfers."
"Sometimes especially zero-day spam emails can be passed to the user's inbox."
"I would rate them as a 1.5. The new hub created in India is not good."
"Sometimes, integration can be challenging, impacting its stability, which is why I rate it a five out of ten."
"The solution needs better support."
"The custom tailoring is limited."
"The reporting aspect of the solution needs improvement."
"In general, our company should make the tool more robust to protect our systems."
"If they want to be the primary or best solution, they need to have better email management features."
 

Pricing and Cost Advice

"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."
"It's a user-base subscription."
"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."
"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."
"Microsoft Defender is expensive. I typically recommend it only if clients have the budget. Otherwise, I would suggest an alternative."
"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."
"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"I believe it's a little costly, but given the faith that we put into it from a security perspective to maintain the integrity of our patient information that is being transferred through this system, that's a small price to pay. So, on the surface, it might look like a lot of money, but depending on the need for security, which is where we feel it shines, it's okay price-wise."
"The price of Kiteworks is reasonable."
"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."
"They changed it midstream. We were being charged a certain flat rate for SFTP traffic. For whatever reason, at the beginning of the year, our pricing changed, and we are now being charged more for using a feature of the product than we were when we first bought it. That has been our experience with billing. It turned out to be more expensive than when we started with it."
"I rate the product price as nine out of ten, where ten is the most expensive, and one is the cheapest. There is no need to pay any extra charges apart from the licensing costs."
"The cost is very high."
"The licensing is on a yearly basis."
"The solution requires a license to be purchased for every user."
