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.

Improved email threat visibility and security posture through adaptive reputation and analytics
I have experience with Cisco and other vendors like Sophos. I have more than 10 years of experience in this field. I worked with the Adaptive Reputation Management feature of SonicWall. Machine learning plays an important role in updating threat intelligence, particularly with SonicWall. The pricing for SonicWall Email Security is reasonable and budget-friendly. My overall rating for SonicWall Email Security is 8 out of 10 because, apart from the areas that need improvement, it was overall good.

Quotes from Members

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

Pros

"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 benefits that Kiteworks has provided to its customers in terms of data sovereignty."
"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."
"As a file-sharing application, it's an absolute 10 out of 10."
"The most valuable aspect of Kiteworks is undoubtedly the private content network. This feature is particularly beneficial for us. Furthermore, it serves as a centralized platform that enables us to track and manage our information exchange."
"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."
"It’s a great product that you should seriously consider and take the first step by training."
"Behind the reason we chose SonicWall for my company is it has excellent packet analysis of normal and SSL encrypted traffic, application intelligence visualization and control, multiple Gigabit Ethernet LAN and WAN ports, flexible configuration and redundancy options."
"It is a very scalable solution."
"Beside a few issues with specificity in the email protection controls, this product is very good at handling email security."
"This solution has been really good for us and I recommend using it."
"This solution provides very good email security that protects us against spamming and malware."
"SonicWall Email Security uses multi-layer cloud security."
"The pricing for SonicWall Email Security is reasonable and budget-friendly."
"The product is easy to manage in terms of configurations."
 

Cons

"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."
"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."
"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."
"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."
"We have experienced some issues with stability due to bugs."
"In my experience, their technical support can be a little slow."
"There is one particular thing that is a nuisance."
"Policy deployment could be time consuming and represents an area for improvement in SonicWall Email Security."
"The after-sale support needs improvement. They don't have representation in my country."
"They need well-trained partners in Nigeria."
"The pricing could be improved."
"Updates could be released more frequently."
"There could be definition updates included in the subscription."
"Overall, this is a solution that provides good security but at a very high cost."
"SonicWall Email Security is scalable, but the price per license is expensive."
 

Pricing and Cost Advice

"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"The price of Kiteworks is reasonable."
"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."
"The license management is changing and confusing. If I could make one change to it, it would be better license management through the API."
"When compared with Cisco, it is very well priced. Cisco is very expensive."
"Our customers purchase the solution's yearly license."
"The platform offers a yearly license."
"I rate the application’s pricing a five out of ten."
"We have a two-year license subscription and the price is very high."
"The overall price of SonicWall Email Security should be reduced and there should be an option to purchase one or two licenses more instead of their current policy of bulk increases only. There should be more flexibility in the licensing model. Each license cost approximately $33 annually."
"The cost is cheaper than Sophos. I would rate it as five out of ten."
