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.

Excellent technical support, easy to install, but the price, while affordable, could be improved
Office 365 is scalable, but it is dependent on the situation. We don't have a problem with it from an organizational standpoint. They started with 100 employees and then added another 500 after six months, for a total of 600 employees. The setup of new users, new emails, and new applications to be assigned to the new users is straightforward. They also provide the PowerShell command, which they provided more, development type, like, for example, you can create users, not manually, but through a script that can create users, for example, 100 users in two, three minutes, and you don't do it manually. They're fantastic. My portfolio contains approximately 50 companies. Office 365 is our primary platform for the 50 companies. I only have one on G Suite, and the majority of them will be migrating from G Suite to 365 in the coming month.

Quotes from Members

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

Pros

"The solution removes the limitations with file attachment size that is found with regular email."
"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."
"Scalability is impressive."
"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"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."
"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"I love all of the applications being interlinked. I do not have to separately work on an independent system when it comes to file storage, email, and other tools."
"It's inexpensive to license."
"It is very easy to deploy."
"The most valuable feature of this solution is the integration."
"The most valuable feature is Microsoft Exchange."
"There are no more server and hardware operational costs and downtime, updates, etc. for all the workloads available. Newer features and updates are available immediately. Can be managed from a single web interface. Cloud-based, so same experience for all users, regardless of location."
"My primary use case is for preparing presentations to teach, often on PowerPoint."
"I like that it is cloud-based, wherefrom any computer I can access my documents and continue working."
 

Cons

"In my experience, their technical support can be a little slow."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"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."
"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."
"File location could be improved."
"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."
"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."
"It could be more user-friendly for inexperienced people."
"They should do more testing before product releases."
"Sometimes the configurations of the error troubleshooting are pretty problematic and there are a lot of issues that happen even if you follow the step-by-step guides. They can work on fixing this issue. If there are a lot of issues in your Windows or your Office or anything, you restart your PC and it works. They need to get rid of this need."
"Their support is so terrible and unusable except during dire emergencies."
"Data protection and email security are almost the same for all the organizations, irrespective of their segment (SMB or enterprises), with standard subscription at least basic Data loss prevention and Advance threat protection can be enabled for SMB segments, it is available in enterprise version / Premium versions."
"There are several additional features we would like to see, such as advanced features of SAN protection in Office 365. The main thing is the SAN protection; we would like to see a lot of advanced features added because we had a lot of spam attacks."
"Sometimes the synchronization between the desktop and online is a little bit slow."
"The one big problem with the solution is if you are presenting in Teams and someone puts their hand up, you don't get a notification. If you are running a meeting and just presenting you don't know that people have their hands up and want to ask a question."
 

Pricing and Cost Advice

"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."
"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."
"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."
"Good reporting and good value subscriptions for international calls."
"Licensing fees are paid on a monthly basis, or we prepay them."
"The pricing is good for all the features that we receive, e.g., Skype for Business."
"For the moment, we are paying on a monthly basis because we are still adapting the support and how we want to proceed. I think we will move to paying for the annual license."
"I would rate the solution 3 out of 5 for the price. I think Microsoft presents a good solution concerning the price."
"Licensing, billing, and accounting are available from the management interface."
"The pricing is not really high, but one can get the software with the license key for free."
"​The pricing/licensing is easy to manage."
