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

"The solution removes the limitations with file attachment size that is found with regular email."
"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."
"I can identify from which region our users are uploading or downloading files."
"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."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"The solution can be used remotely; it's easy to upload and share files."
"I cannot guarantee any email by its name. It can be spam. Sophos Email helps to double-check whether an email is spam or not. It has a dashboard which gives an overview of the alerts."
"Sophos Email provides both inbound and outbound filtering."
"The platform is scalable when installed on server-based systems."
"The feature of Sophos Email that we find most effective for detecting suspicious emails is primarily based on their signatures."
"The best thing about it is the logs."
"The deployment is very easy. It's quite straightforward."
"The most significant aspect is the response filtering concerning attachments and links."
"It is a stable solution...It is a scalable solution."
 

Cons

"It could be more stable. In the next release, it would be better if it was more stable with improved performance."
"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."
"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."
"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."
"Perhaps there could be a notification to users about their bandwidth or network packet loss."
"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."
"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."
"The main drawback is regarding the technical support."
"A lot of legit emails get quarantined."
"Sophos Email can improve mail security."
"Sophos Email can improve security."
"The solution has not found a way to block certain kinds of phishing emails."
"The solution should be able to support the cloud environment."
"The tool's pricing is expensive. In its future release, the tool should make reporting easier to view."
"The solution's sandboxing and spam control features could be improved."
 

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."
"It is not really expensive. I mean, to me it's obviously expensive, but it's worth it."
"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."
"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 pricing is quite reasonable, with a fixed cost and no additional charges."
"Sophos Email is priced lower than its competitors."
"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."
"Licensing is paid on a yearly basis."
"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 is fair."
"It falls somewhere in the middle—it's not excessively expensive nor very cheap."
"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."
