Streamlined global file sharing with user-friendly interface and self-service capabilities

I'm not a network expert, however, there must be some room for improvement. Perhaps there could be a notification to users about their bandwidth or network packet loss. If users receive such notifications, they can understand any disruptions are due to issues with their network or bandwidth rather than the site or Kiteworks. Additionally, I work from offshore India, and I told my client manager to communicate with the Kiteworks forum salesman regarding one feature. 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.

Reliability and threat intelligence make this solution competitive, but AI improvements can further enhance its effectiveness

The best features of Trend Micro Deep Discovery Email Inspector include its reliability. The second valuable feature is its built-in sandbox feature, allowing for inspection of incoming emails and attachments. The sandbox is an appliance that opens any attachment in an enclosed environment to assess its impact and potential for viruses. This protects the network from harmful threats. Trend Micro has a very large R&D team with excellent threat intel, allowing them to provide better solutions than some competitors. They understand emerging threats based on the information from their EDR. The key strengths can be summarized as reliability, a good integrated one-box solution that includes a sandbox, and their R&D capabilities and good ratings, which lead to better threat intelligence. The detailed threat intelligence provided by Trend Micro Deep Discovery Email Inspector is valuable in understanding the behavior and tactics of potential email threats.

Quotes from Members

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

Pros

"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."

"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 could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."

"The most valuable aspect of Kiteworks is undoubtedly the private content network. This feature is particularly beneficial for us. Furthermore, it serves as a centralized platform that enables us to track and manage our information exchange."

"I can identify from which region our users are uploading or downloading files."

"Scalability is impressive."

"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 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."

More Kiteworks pros

"The most valuable feature of Trend Micro Deep Discovery Email Inspector is the simple analysis of phishing emails."

"I find Trend Micro to be a good solution for security purposes."

"The solution's most valuable features include visibility into the network and fast sandboxing technology for alerts, though response time can vary."

"The best features of Trend Micro Deep Discovery Email Inspector include its reliability."

"It can effectively monitor outbound and inbound devices."

"I highly recommend Trend Micro Deep Discovery Email Inspector due to its security and scalability features."

"I would rate the solution's stability at ten out of ten."

"Trend Micro is a very good product."

More Trend Micro Deep Discovery Email Inspector pros

Cons

"The one feature, which I have also requested directly to Kiteworks, is to have a scheduled upgrade function. Currently, one of my engineers logs in after hours for the upgrade. We're a hospital, and we're 24/7, but the primary users are seven to five. So, we log in the early evening just to push a button to tell it to do the update. It would be nice if that could be very easily scheduled."

"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."

"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."

"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."

"It could be more stable. In the next release, it would be better if it was more stable with improved performance."

"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."

"Perhaps there could be a notification to users about their bandwidth or network packet loss."

"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."

More Kiteworks cons

"Trend Micro's technical support has room for improvement. More efficient support should be provided, especially for standard support."

"Trend Micro Deep Discovery Email Inspector could improve by making it easier to use. Microsoft solutions are easier to use."

"Trend Micro's technical support has room for improvement."

"The product's feature for message processing and blocking devices for bulk emails needs improvement."

"I would like to be able to send emails to a specific sandbox. This is a feature I would like to see added to the next release."

"The tool needs to incorporate faster response times for issue detection, more detailed reports, and better compatibility with older operating systems (e.g., Windows 7, 8, Server 2012)."

"To improve Trend Micro Deep Discovery Email Inspector, it should have updates with better AI and ML-based integration."

"It could be more user-friendly, easier to install, and lighter on the network. I would say that for all products because you do not need technical expertise to take care of it. When you have a user-friendly solution, it makes it easier for the vendors or companies like us. We do not have to go to the client's site to attend to issues all the time. Because it is user-friendly, they can take care of it after some training."

Pricing and Cost Advice

"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 price of Kiteworks is reasonable."

"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 solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."

"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."

"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."

"We pay for an annual subscription for this email security solution."

"The solution's pricing is high, and I would rate it an eight out of ten."

"It's an expensive solution, and you may not see a return on investment in a short period of time. However, you will see a return over a long period of time."

"The price of Trend Micro Deep Discovery Email Inspector is less expensive than Microsoft solutions."
