AI has helped classify threat types more accurately but product ownership can improve
Ease of use is important, and Abnormal Security's responsiveness and ability to deliver solutions when issues arise are crucial. However, there is always room for improvement, as achieving a perfect 10 means there is no more room for enhancement. For Abnormal Security, it's about leveraging AI even more, which they are already working on in their roadmap.

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.

Quotes from Members

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

Pros

"It protects us from being business email compromised, which is invaluable for maintaining our security."
"What I like about Abnormal Security is that it notifies me if any of my partners or suppliers are experiencing a security breach by analyzing their database and identifying potential cyber threats."
"I like Abnormal's threat protection with auto-remediation, but I also love its abuse mailbox feature, which automatically responds to the end user. That feature has a super-valuable security component and helps improve the user experience."
"I have never encountered any stability issues with Abnormal."
"I would recommend Abnormal Security."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"It does some really cool stuff that other tools aren't doing. We found it to be really effective, and the AI/ML functionality is really what differentiates them."
"Abnormal Security's AI capabilities are what we like most, as they can categorize and classify the emails, and based on the context of the email, understand if it's a graymail, a bulk mail, or a phish."
"I can identify from which region our users are uploading or downloading files."
"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."
"It’s a great product that you should seriously consider and take the first step by training."
"Scalability is impressive."
"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"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."
"As a file-sharing application, it's an absolute 10 out of 10."
"The solution can be used remotely, including from mobiles, and it's easy to upload and share files."
 

Cons

"When we're working on something as engineers, and we find an idea or a method of doing something that would be greatly improved by doing it another way, there should be an ability for me to click the ideas button, type in an idea that I have, and submit it to a product review team or developers to have them think through the process a little bit more."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"I would like to have the ability to customize the auto-remediation feature."
"Abnormal should add more automatic reports. I have an open request to our account team for more notification and report types that can be sent automatically. For example, they have an awesome report that gets sent weekly, and I also want them monthly, so I don't need to do so much adding up when my director wants numbers over time."
"One feature I'd love to see is outbound scanning."
"There could be more selectable options and more granular selections available."
"The biggest pain point for us is the lack of support for on-premise email systems."
"There could be room for improvement in enhancing integration with other cybersecurity tools."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"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."
"There is one particular thing that is a nuisance."
"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 system is extremely stable, but because it is a "COTS" system access is restricted and you must use the solution's support to make even simple changes, which increases the downtime."
"In my experience, their technical support can be a little slow."
"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."
"We have experienced some issues with stability due to bugs."
 

Pricing and Cost Advice

"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"The license is based on the user count, so the number of users that have an email address in the organization."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"The pricing appears fair, and they demonstrate a genuine willingness to work with us on 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 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."
"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 is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."
