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.

Stronger email and mobile security has protected users from ransomware and simplified management

Price is obviously a challenging part, and I think it is the biggest problem we have suffered from over the last two or three years due to a 7 to 8% hike per year, twice a year, which is why we have some renewals on Sophos Email, Sophos XDR, EDR, and the firewall, but due to price hike, they are unable to renew it. The price is going to be very high. It would be better if Sophos can provide a more flexible pricing model for different types of businesses. Price could be lower. The main competitor for Sophos in the market is Palo Alto, which has reduced their price by more than 35 to 40%, making it a very challenging part to sell this product. Palo Alto provides the same functionality for email security, which adds to the challenge because the price is going very high.

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."

"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 benefits that Kiteworks has provided to its customers in terms of data sovereignty."

"Scalability is impressive."

"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 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."

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

More Kiteworks pros

"The platform is scalable when installed on server-based systems."

"The best thing about it is the logs."

"I find the comprehensive features of Sophos Email most valuable."

"Sophos Email offers encryption and malware protection, provides visibility into emails, has 99% accuracy in catching spam, enhances organizational safety, integrates with various vendors like Microsoft, is deployable with any email service, prevents data loss, features authentication rules, synchronizes with Active Directory and Azure, and includes a self-service portal. The product is very flexible."

"I have found Sophos Email to be scalable."

"When you say email security, it's about everything, incoming email, outgoing email, spam, phishing emails, unwanted marketing emails. You can set rules, but the main feature of Sophos Email is to make sure you don't get hacked. 95% of people who are hacked do not get hacked by typing the router password. They are hacked from the inside out, which means they send you a document that is a zero-day attack, you open it, nothing happens, but technically the attack is running in the background of your computer. This is how they gain access to your PC."

"The anti-malware, risk scanning has been pretty spot on."

"The deployment is very easy. It's quite straightforward."

Cons

"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."

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

"File location could be improved."

"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."

"It could be more stable. In the next release, it would be better if it was more stable with improved performance."

More Kiteworks cons

"The security of the solution could improve."

"A lot of legit emails get quarantined."

"The installation of Sophos Email could be easier. It's a bit difficult because setting up the email virtually requires some bit of technical knowledge."

"Sophos Email could improve DLP features."

"However, the setup was tricky, particularly with the DNS routing between Microsoft Exchange Online and Sophos cloud services. It took me about four attempts to get it working correctly. Despite that, Sophos Email does everything we need, so we don't require any additional capabilities now."

"Email installation could be more user-friendly so that it can be done without involving the partner"

"Sophos Email has few improvements to implement, including the handling of incoming emails in the systems. It needs to add additional feature that helps in enhancing the scanning processes of these emails. While adding these features, it should work towards improving the current features also."

"Sophos Email can improve mail security."

More Sophos Email cons

Pricing and Cost Advice

"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 license management is changing and confusing. If I could make one change to it, it would be better license management through the API."

"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 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."

"There is an additional fee for their central managed console."

"Licensing is paid on a yearly basis."

"It is an expensive solution. On a scale of one to ten, where one is low price, and ten is high price, I rate the pricing a seven."

"Sophos Email is neither cheap nor expensive."

"I would rate the pricing of Sophos Email as a six. It is considered affordable as a standalone product, and there are no additional costs besides licensing. The pricing is fixed."

"We use exchange licenses, for which we get immediate support from Sophos."

"I rate the product's pricing a seven out of ten."

"The tool's price is reasonable. On a yearly basis, there is a 20 percent increase in prices, but it is not an issue."
