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.

Quotes from Members

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

Pros

"My experience with customer support and technical support for Microsoft Defender for Office 365 has been excellent."
"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."
"Some of the valuable features on the email side are anti-phishing, anti-malware, and Safe Links."
"Our customers are satisfied with Defender for 365 because Microsoft products are easy to use and customize to meet the client's needs. Everything is in one place, so we can adjust policies as needed for phishing, DLP, ATP, or any other security features that our clients want to apply."
"The product is not resource-intensive."
"The deployment capability is a great feature."
"The basic features are okay and I'm satisfied with the Defender."
"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."
"The most valuable feature is the ability to allow end-users to manage their own information and data with minimal administration. That's the best feature from my perspective."
"Scalability is impressive."
"The solution removes the limitations with file attachment size that is found with regular email."
"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 can be used remotely; it's easy to upload and share 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."
"I can identify from which region our users are uploading or downloading files."
"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."
"The solution provides protection with its Email Track Records and Machine Manual features."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"With Trend Micro email security gateway, we can deploy features like DLP and BEC."
"The technical support services are excellent."
 

Cons

"We are always looking for others tools to increase automation on tasks. There can be better integration with other solutions, such as PowerPoint and email."
"Microsoft Defender for Office 365 must improve the overall management style, including the GUI. It also needs to change the filters so that it is easy to whitelist and blacklist data."
"The pre-sales cost calculations could be more transparent."
"Microsoft should provide more documentation for users so they can self-educate. I would like to see more documentation for advanced security features."
"The visibility into threats is not up to the mark, as I do not have control. I rate my experience with Microsoft Defender for Office 365 as six out of ten due to troubleshooting and pricing concerns."
"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."
"Microsoft wants its well-paying customers to finish testing some of its half-baked products, find bugs, and report bugs back to Microsoft's team, which is a little frustrating for those who have to manage it and roll it up to thousands of people across the organization."
"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."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"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."
"In my experience, their technical support can be a little slow."
"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."
"There are always issues when there are bugs or upgrades. The challenge with upgrading is getting more storage from the customer. Every time we have a new version, it requires additional storage. This means that the customer would need to procure more storage for their server, which they don't like because it means additional cost to them. So, I think my request would be that the version upgrades don't require any significant storage requirement."
"Perhaps there could be a notification to users about their bandwidth or network packet loss."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
"The product's pricing could be more flexible."
"The solution's pricing could be improved."
"There is room for improvement in content filtration, expressions, file sharing, and policy configuration."
 

Pricing and Cost Advice

"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 license is expensive because the cost is based on the number of users."
"From the pricing point of view, like any other product in the market, there is scope for negotiation."
"The pricing is normal. Considering its popularity, it's not overpriced."
"Microsoft Defender for Office 365 comes with Microsoft Windows. It is free with the operating system."
"Microsoft Defender for Office 365 is an add-on to the Office license. Many customers are purchasing this solution."
"The pricing has become expensive."
"I know that the product is incredibly expensive."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
"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."
"The price of Kiteworks is reasonable."
"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."
"Trend Micro is an expensive solution."
"I rate Trend Micro InterScan Messaging Security’s pricing a seven out of ten."
