Taha Khaleel - PeerSpot reviewer
A highly reliable solution that provides monitoring capabilities and protection to multiple types of devices
The initial setup of Kaspersky Security for Mail Server is very easy. The initial setup of Kaspersky Security for Mail Server takes around four minutes. The solution is deployed on the cloud and on-premises. For the deployment process, you can buy the solution in a CD form or purchase it directly from the company website and activate it. My company needs managers, engineers, and developers to deploy the solution. The number of people required for the deployment process changes from time to time, so all the staff are included not just for the deployment of the solution but also to make improvements to the solution in the future. You can contact Kaspersky to see if they can provide the solution with integration capabilities for your company by providing you with an open account, which I haven't tried yet, though I plan to try it in the future.

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.

Quotes from Members

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

Pros

"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."
"The integration rate is very high in Kaspersky, which is why most of our customers like it."
"You can install the plugins on the same machine hosting your exchange solution. It's a good complement for Sophos security, which scans the traffic before it reaches your mail service. Kaspersky is on the mail server itself while Sophos handles the incoming traffic. With both of them working together, we have the perfect solution for mail."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"The most valuable feature is the straightforward setup."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"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."
"I can identify from which region our users are uploading or downloading files."
"We could see whether the customer with whom we shared a file had downloaded it, which was not available with GitHub."
"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 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."
"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."
 

Cons

"I rated the overall solution a five out of ten. If a user is looking for a low-budget solution with mid-level security without AI features, Kaspersky Security for Mail Server is suitable."
"The biggest problem in the solution is related to its license renewal since it is pretty hard in Kaspersky to find out the procedure to renew a license."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"I have only made contact via email, and it is a little slow. I would give customer service a rating of six or seven. Improving Spanish support would greatly benefit users."
"The solution is not 100 percent stable and that can use improvement."
"It would be great if Kaspersky could do what Sophos does for us. However, we love having these two different technologies doing the same thing. Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"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."
"We have experienced a few hiccups and bugs when using the admin console and from a user perspective."
"Perhaps there could be a notification to users about their bandwidth or network packet loss."
"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."
"File location could be improved."
"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 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."
"In my experience, their technical support can be a little slow."
 

Pricing and Cost Advice

"The solution offers one of the best prices possible to its users, making it even better than Barracuda. Kaspersky Security for Mail Server is ten times cheaper than Barracuda."
"My company makes annual payments towards the licensing costs solution."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"The solution is not expensive."
"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."
"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."
"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."
