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.

CV
Cobe Van Coller

Cloud security has improved remote access and has reduced costs for smaller client sites
I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

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

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Cloudflare is simple to use."
"The tool also offers good scalability, and the dashboard, along with real-time analytics, is very good."
"Cloudflare, in my opinion, was easy to implement."
"What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"Cloudflare Access is part of the Zero Trust philosophy."
More Cloudflare One pros
"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 benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"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 like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"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 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."
"Scalability is impressive."
More Kiteworks pros
"The initial setup of Microsoft Exchange Online Protection was easy."
"The initial setup was easy. The configuration process is very straightforward."
"Microsoft Exchange Online Protection (EOP) is the best email solution with more features and robust security, making it ideal for corporate use."
"The threat management feature includes policies and alerts that are valuable."
"It provides security to both on-premises and Azure infrastructures."
"We can migrate seamlessly without any disruptions to our operations."
"The pre-set policies and configuration analyzer are the most valuable features."
"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."
More Microsoft Exchange Online Protection (EOP) pros
 

Cons

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"Operating and tuning the product is difficult."
"When there are any dynamic changes in complex applications, the tool takes a lot of time, making its analytics-related area a major matter of concern where improvements are needed."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"The response time for support must be reduced."
"They don't have a person to provide support for customers using the solution under their free plan."
"The initial onboarding was causing us some confusion."
"The onboarding process can be improved a little bit."
More Cloudflare One 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 have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"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."
"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 could be more stable. In the next release, it would be better if it was more stable with improved performance."
"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."
More Kiteworks cons
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"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."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"We would like the solution to have more in-built intelligence in the way that it reviews potential security risks, rather than our team constantly having to update the policies."
"When the product is being updated, it changes some of the setups. The support team is also not good."
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"We have experienced issues while migrating from on-prem to the cloud. The tool needs to improve its stability."
"The reporting needs a little bit of improvement."
More Microsoft Exchange Online Protection (EOP) cons
 

Pricing and Cost Advice

"The prices are slightly expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"Cloudflare Zero Trust Platform's pricing is good."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The solution is not that expensive."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The solution's pricing lacks transparency."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"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."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"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."
"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 expensive but is backed by Microsoft's reputation."
"The tool's pricing is excellent."
"The product is bundled with Microsoft 365."
"The price could be lower."
"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."
"The price of Microsoft Exchange Online Protection is reasonable."
"The pricing of the solution is reasonable."
"Online Protection is fairly expensive."
