Sukkanta Banerjee - PeerSpot reviewer
Two-factor authentication and .ZIP format make large file transfers very secure
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. Also, only the .ZIP format is supported because it is a very secure mode of file transfer, and that is why it is recommended. It also has built-in antivirus, so if it detects any malware it will quarantine the file and it won't be delivered. This is really important to keep the service up and running in a proper and secure manner. With people working from home, the data needs to be checked to see what kind of data is being sent. It has a two-factor authentication mechanism. For example, if a person with a particular domain is using Kiteworks and sends a file to a party outside of his domain, that external party has to go through two-factor authentication. The receiver gets a link that takes them to the setup of a temporary account, which will be valid for three days. The recipient will also receive a customized password separately. Only after all these steps will they be able to access the file. That access is only available to a person with the mail ID to which the file was sent. In addition, admins can see who is sending sensitive content, what that content is, and to whom it is being sent, and can track emails. One week of good training will give a user complete knowledge for using the solution. The system is very easy to use. You just click on "Compose," attach a file, and send it. It's very easy compared to Outlook or Teams. It's quite simple, even for someone logging in for the first time. It is very smooth and easy to send files.

Achieving Seamless Email Security and Encryption while Managing Temporary Email Storage Limits
We continue to use Sophos products and remain with the company. For firewall protection, we use XGS systems. We have provided Sophos Email Gateway for one of our clients. We have integrated Sophos Email with our internal email server, using it for both outbound and inbound traffic. Integration with Office 365 protection for Sophos Email Security works smoothly without any challenges. The solution is totally cloud-based. I recommend Sophos Email for mid-sized companies as it is a good option, though it may not be ideal for large-scale or small businesses. I have not tried incorporating AI technology with Sophos Email yet. I am Bhanu Prakash, Technical Head for Systek Services, and can be reached at b.hanu@teamsistek.com. I am a partner with Sophos. Overall rating for Sophos Email: 10/10.

Quotes from Members

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

Pros

"I can identify from which region our users are uploading or downloading files."
"I like Kiteworks or Accellion because it's continuously upgraded. I also know that it probably works with a lot of clients."
"The solution can be used remotely; it's easy to upload and share files."
"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."
"Scalability is impressive."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"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."
"Good VIP protection, time of click protection and the Sandstorm feature."
"Sophos Email is in the cloud and integrated with its firewall."
"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."
"The solution's identity proxy feature is very good and reliable."
"I rate Sophos Email nine point five."
"I found the user interface friendly."
"The best thing about it is the logs."
"The anti-spam functionality of Sophos Email is good."
 

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."
"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."
"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."
"File location could be improved."
"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."
"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."
"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"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."
"The tool’s stability should be improved."
"Sophos Email can improve mail security."
"Sophos Email needs to increase the number of promos."
"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."
"Servicing and support are areas with shortcomings where the solution needs to improve."
"A lot of legit emails get quarantined."
"The main drawback is regarding the technical support."
 

Pricing and Cost Advice

"The solution is very expensive because we are buying with Malaysian Ringgit and it's sold in US dollars."
"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."
"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."
"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."
"It falls somewhere in the middle—it's not excessively expensive nor very cheap."
"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."
"The pricing is quite reasonable, with a fixed cost and no additional charges."
"The pricing is affordable, so I’d rate it around a four out of ten on the pricing scale. We pay about fifty pounds a month, including hardware so that costs may differ without it."
"Sophos Email is a little expensive for us, but it's necessary. We have a subscription and renew it every three years."
"Sophos Email is priced lower than its competitors."
"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."
"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."
