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.

Comprehensive detection has protected email traffic and now simplifies endpoint security work

Sophos Email security is the primary product I use. It scans all your inbound and outbound email for malware. It also has a capability for looking for phishing and spear phishing content and blocking it. Email has an extended capability that includes what's called a secure web gateway. All user traffic gets managed through that, making it a combination product. The version of the product you run determines which features are available. Reporting is competent. There is scope for more improvements, which they will do as they do every year regularly. They keep updating the product. Reporting gives you the relevant details of what is happening, so it's mature on that front. The main benefit is security for your email. The beauty of the Sophos system is that the XDR functionality runs across the system. Sophos, Trend Micro, and Microsoft are the only three that have a very strong system with this concept. XDR stands for extended detection and response, and it's a technology where the system automatically exchanges security signals between the endpoint, the email, and other similar products of the same brand. If you have Sophos Endpoint and Sophos Email, you have very good connectivity from the endpoint to the cloud at the email level and to some extent onto the browsing traffic. You have a very rounded security aspect.

Quotes from Members

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

Pros

"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."

"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 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."

"As a file-sharing application, it's an absolute 10 out of 10."

"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 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."

More Kiteworks pros

"It's easy to use and the configuration is straightforward."

"The most valuable feature of Sophos Email is the sandbox. We're able to scan the file, isolate it, and look at it before it is delivered. It is highly effective."

"You will find a lot of value in this solution and the small difference in price should not matter, it does protect well."

"The solution's identity proxy feature is very good and reliable."

"There are many features that are important, but among those, the spam protection feature is very valuable. It help us to safeguard the email against phishing and ensures that there is maximum security enabled for our communication processes. It has a huge role in protecting our emails from potential threats."

"Our client recently received many emails, and their employees didn't realize these emails were phishing attempts. Consequently, they clicked on them and fell victim to the attack. Therefore, it is important to secure their system with Sophos Email Security."

"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."

"Sophos Email provides both inbound and outbound filtering."

More Sophos Email pros

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."

"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."

"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."

"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."

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

"We mainly had stability issues with kiteworks, where we were pushing the limits of its capability."

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

More Kiteworks cons

"I would like to see improvements in the initial setup process, ensuring better compatibility with diverse customer infrastructures."

"Sophos Email does not work with split delivery. If I have a domain with 100 mailboxes and want to protect only 50, it is not recommended by Sophos or not possible to configure."

"The solution's technical support is slow and unresponsive. You need to book time in order to get support."

"The solution should be able to support the cloud environment."

"Lacks visibility into spam emails."

"The security of the solution could improve."

"The tool has some performance issues and bugs, making it an area where improvements are required."

"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."

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."

"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."

"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."

"The price of Kiteworks is reasonable."

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

"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."

"The pricing could improve by having additional discounts. For example, when customers buy have more than 50 or more users, there should be additional discounts."

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

"Sophos Email is priced lower than its competitors."

"Most of our clients are on a perpetual license. If there is a budget issue, they can choose a subscription. However, most of the clients choose the perpetual license."

"Sophos Email is a little expensive for us, but it's necessary. We have a subscription and renew it every three years."

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

"Licensing is paid on a yearly basis."
