Sukkanta Banerjee - PeerSpot reviewer
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.

Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.

Quotes from Members

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

Pros

"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"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 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."
"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."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"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."
"The solution can be used remotely; it's easy to upload and share files."
"It is an easy solution."
"It has a really nice web-based administration console."
"The scalability is pretty good; it does what it is supposed to do."
"The initial setup of Microsoft Exchange Online Protection was easy."
"The pre-set policies and configuration analyzer are the most valuable features."
"Microsoft EOP's most valuable feature is a shared mailbox."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"I rate Microsoft Exchange Online Protection (EOP) nine out of ten."
 

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."
"File location could be improved."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"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."
"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."
"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."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"The tool's classification for bulk email is cumbersome."
"Some features, like encryption, are not available."
"It would be helpful for customers if Plan 1 features were included with EOP."
"The solution must improve the user experience."
"The security compliance features need to be improved. Sometimes, a client's mailbox becomes full because of retained information and not because of mail. I would like to see improvement in block rules as well."
"Our company faces difficulty with Microsoft Exchange Online Protection (EOP) because it's too big, clunky, and difficult for a small client to implement quickly and easily."
 

Pricing and Cost Advice

"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."
"The price of Kiteworks is reasonable."
"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."
"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 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 could be lower."
"Regarding the price, it's comparable to other service providers. We've also looked at Check Point's offerings, and the pricing doesn't seem to be an issue."
"The product is expensive."
"Apart from the license fee for the solution, there are no additional costs."
"The product is bundled with Microsoft 365."
"The solution's pricing is subscription-based rather than a yearly licensing cost. Pricing is based on the size of the environment and company and can be expensive."
"The solution should reduce the cost."
"Online Protection is fairly expensive."
