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.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

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 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."
"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 removes the limitations with file attachment size that is found with regular email."
"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."
"Scalability is impressive."
"The solution can be used remotely; it's easy to upload and share files."
"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 product protects against malware."
"With Microsoft Exchange Online Protection, if malware is attached to a mailer, it's very easy to go into the incident alert and find out what's happening with that identity and the mail."
"We like the holding facility that is available for potentially suspicious URL's. This allows a real-time review to be performed before the email reaches a users inbox."
"We use the solution in all our environments. We use it for remedy tickets and give them updates. It was our main communication point."
"It offers great security against malware and other threats."
"The most valuable feature of Microsoft Exchange Online Protection is the accidental release of information protection capabilities. Additionally, the solution is easy to use."
"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
 

Cons

"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."
"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."
"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."
"In my experience, their technical support can be a little slow."
"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."
"File location could be improved."
"Perhaps there could be a notification to users about their bandwidth or network packet loss."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"The solution lacks to elaborate on its spam policies."
"The tool's classification for bulk email is cumbersome."
"Some features, like encryption, are not available."
"Our Exchange system is very locked down and secure, yet we still got hacked."
"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."
"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."
 

Pricing and Cost Advice

"The price of Kiteworks is reasonable."
"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 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 license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
"The product's pricing is competitive for the US market."
"It is a low-price solution."
"The product is bundled with Microsoft 365."
"The product is expensive."
"The pricing of the solution is reasonable."
"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."
"Online Protection is fairly expensive."
"The solution is expensive but is backed by Microsoft's reputation."
