Provides reliable real-time email protection and offers competitive pricing features

Regarding Kaspersky Security for Mail Server, I have not compared with other solutions, but I will compare and provide feedback. It is a reliable and fast security solution, and I can say it blocks better than other competitor software. Kaspersky Security for Mail Server has support for Windows and Linux, but regarding improvement, I have to dig deep and will have to do research on that. I have not checked into much detail about what can be better in Kaspersky Security for Mail Server. I have checked in general. If given some time, I can check and compare with other solutions. Regarding Kaspersky Security for Mail Server, I have found this is quite a good solution. It has a good response and good detection capability. I have not checked other products, so I cannot give any detailed or specific feedback regarding that. From what I have checked from Kaspersky mail security, it is satisfactory.

Has consistently supported security needs for mid-sized teams with affordable deployment

I do not work with Cloud Secure Edge, CSE, or SMA apart from SonicWall NSA. I am not satisfied with phishing protection, as it falls completely under the email domain security. The customizable policy configuration does not help to tailor email security overall because our systems are not integrated with SonicWall Email Security. We are not using reporting and analytics because it requires completely different software. While all required features are available in SonicWall Email Security for SMBs and startups, we lack analytics features. They provide an option to purchase a complete separate product for analytics, but despite initially having purchased the paper license, due to technical limitations or changes, we cannot use that product. Now they require additional fees to access the analytics feature.

Quotes from Members

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

Pros

"The most valuable feature is the straightforward setup."

"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."

"The most valuable features are the anti-phishing and anti-spam capabilities."

"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."

"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."

"The integration rate is very high in Kaspersky, which is why most of our customers like it."

"The most valuable feature of the solution stems from the fact that it is a highly reliable and dependable solution."

"SonicWall Email Security uses multi-layer cloud security."

"The product is easy to manage in terms of configurations."

"Setup was easy. It took about 30 minutes."

"The anti-spam aspect of the solution is its most valuable feature."

"This solution provides very good email security that protects us against spamming and malware."

"SonicWall Email Security uses multi-layer cloud security."

Cons

"The solution is not 100 percent stable and that can use improvement."

"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."

"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."

"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."

"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."

"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."

"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 protection level for email security isn't 100%. I'm still getting some spam and junk mail."

"We would like to see more information on a dashboard about what is happening when it comes to spamming and malware."

"I am not satisfied with phishing protection, as it falls completely under the email domain security."

"SonicWall Email Security could improve by making the file blocking and the release feature easier to use"

"The reporting needs improvement."

"The pricing could be improved."

"The platform's control panel needs enhancement."

"There could be definition updates included in the subscription."

"My company makes annual payments towards the licensing costs solution."

"Our customers purchase the solution's yearly license."

"When compared with Cisco, it is very well priced. Cisco is very expensive."

"The cost is cheaper than Sophos. I would rate it as five out of ten."

"I rate the application’s pricing a five out of ten."

"The overall price of SonicWall Email Security should be reduced and there should be an option to purchase one or two licenses more instead of their current policy of bulk increases only. There should be more flexibility in the licensing model. Each license cost approximately $33 annually."

"The platform offers a yearly license."
