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

"It’s a great product that you should seriously consider and take the first step by training."
"I can identify from which region our users are uploading or downloading files."
"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."
"The most useful feature of this solution is to share files with external parties and we can use this functionality to share files internally too."
"The solution can be used remotely, including from mobiles, and it's easy to upload and share files."
"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."
"The benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"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 pre-set policies and configuration analyzer are the most valuable features."
"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."
"It has a really nice web-based administration console."
"We can migrate seamlessly without any disruptions to our operations."
"The initial setup of Microsoft Exchange Online Protection was easy."
"The most valuable features of Microsoft Exchange Online Protection are the EOP, ATP, safe links, fishing, and antispam."
"The initial setup was easy. The configuration process is very straightforward."
"It is easy to configure, easy to use, easy to add exclusions, easy to track, and easy to add anything else if you want."
 

Cons

"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."
"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."
"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."
"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."
"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."
"I think the implementation could be more streamlined."
"The solution can be complex at times. It would be nice to have the on-server version. It needs to improve the stability as well."
"Having orchestration features added to Microsoft Exchange Online Protection, particularly automation and remediation, would be quite useful."
"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."
"The product could be more stable. Microsoft products could be more stable because sometimes, even though they are updating some things, we cannot find those updates."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"I am somewhat happy with technical support from Microsoft. Sometimes it takes a while to get through to the right person or team."
 

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."
"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 price of Kiteworks is reasonable."
"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 solution falls on the higher or more expensive side of the spectrum."
"The product is bundled with Microsoft 365."
"The solution should reduce the cost."
"Microsoft Exchange Online Protection's pricing is a little bit more because its price has recently increased."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
"The pricing for the solution depends on what you are trying to achieve with the use of the product, but I know that it is not a cheaply priced product. Yearly payments have to be made towards the licensing fees of the solution."
"The tool's pricing is excellent."
"On a scale of one to ten, where one is cheap, and ten is very expensive, I rate the pricing a six. For licensing, we can make monthly or yearly payments. Right now, we pay 5 USD per month to secure a person's license."
