Executive SummaryUpdated on Dec 3, 2024

Kiteworks and Microsoft Exchange Online Protection (EOP) are competing in secure communications and email security. Kiteworks has the upper hand in data protection and secure file sharing, while EOP is preferred for email security due to its comprehensive threat protection.

Features: Kiteworks offers secure file sharing, privacy compliance, and robust data protection, making it suitable for enterprises focused on data security. Key features include the ability to send large files, a private content network, and centralized management of information exchanges. EOP provides advanced threat protection with anti-phishing, anti-malware, and spam filtering capabilities, integrated with Microsoft 365, making it an excellent choice for businesses focused on email security.

Room for Improvement: Kiteworks could enhance its user interface to make navigation more intuitive and improve integration with other enterprise applications for greater ecosystem compatibility. Additional reporting capabilities would be beneficial. EOP could improve its complexity in threat management interface, as some users may find configuration challenging, enhance its handling of false positives in spam filtering, and further streamline integration with non-Microsoft systems.

Ease of Deployment and Customer Service: Kiteworks offers customizable deployment options, including cloud and on-premises, backed by direct, personalized support for a smooth setup. EOP integrates seamlessly with Microsoft 365, utilizing a cloud-based model with extensive support from Microsoft's ecosystem, though some users may find the support less personalized.

Pricing and ROI: Kiteworks utilizes a custom pricing model which might require a significant initial investment but offers substantial ROI through its enhanced data security. EOP, often bundled with Microsoft 365, provides a competitive cost structure, delivering ROI through its strong email protection features, with cost efficiency being a major attractive point.

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 solution removes the limitations with file attachment size that is found with regular email."

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

"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 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."

"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 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 best part of this solution is that we can generate multiple reports about how the data is transferred and about user information or IP."

More Kiteworks pros

"The security features provided by Microsoft are robust."

"Microsoft Exchange Online Protection has features like DLP (data loss protection), Safe Attachment, and Safe Links."

"The solution uses artificial intelligence and machine learning, so you don't need train it to detect something. The detection and response times are short. It's an excellent product."

"In general, my company is happy with Microsoft support...My company hasn't faced any stability issues with the solution."

"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."

"The product's most valuable feature is third-party integrations."

"It is an easy solution."

"You can use the product to create special accounts."

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."

"There is no offboarding process for end-users in Kiteworks. It's a manual process. There is no automated syncing with LDAP and checking to see if the account is still active. It's a manual process to get people out of here, which isn't the best way."

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

"In my experience, their technical support can be a little slow."

"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."

"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."

"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."

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

More Kiteworks cons

"The price of Microsoft Exchange Online Protection could be reduced to make it more competitive."

"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."

"Performance and speed should continue to be improved."

"The solution needs to improve its backup."

"It would be helpful for customers if Plan 1 features were included with EOP."

"The solution lacks to elaborate on its spam policies."

"It wasn't easy or intuitive enough for me to start using it. So, the reason was that the solution changed."

"The product's end-of-life cycle could be extended."

Pricing and Cost Advice

"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."

"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 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."

"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."

"It's a high price."

"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 pricing of the solution is reasonable."

"The solution should reduce the cost."

"The solution falls on the higher or more expensive side of the spectrum."

"The product is expensive."

"The solution is priced high and could be less expensive compared to other solutions."
