Secures email by identifying threats and managing email policies effectively
The intuitive management interface feature makes email security policies very easy to implement as it's all about features that need to be enabled or disabled. Our investigation in any incident or mail is very useful as it provides all details about incoming mails, enabling thorough review and detection. The real-time threat intelligence feature is particularly useful as it detects all kinds of threats identified by incoming mails. The Impersonation license utilizes AI tools. Sometimes some phishing mails are reported as phishing, but they are not actually phishing mails. They are detected due to certain words and languages that appear suspicious but were generated by AI tools. Everyone or an advisor may use it for their own purpose or learning, even though it indicates that the mail detected is phishing when it's not.

Quotes from Members

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

Pros

"It can scale."
"It is a really good product with a lot of features. It is responsive, updated, and modern. It is easy to use and has an easy interface for non-IT users. Its dashboard is also quite fine. It is also quite flexible and has an API at the backend."
"The solution's anti-spam features are its most valuable aspect."
"It catches a lot of things and has the ability to add domains as well as add senders and update their things."
"It is a very stable solution."
"The anti-spamming and anti-phishing features are great; they're really strong and stable in this solution."
"It seems good in terms of spam blocking and virus blocking; it is lightweight, and we can filter all of our inbound and outbound emails, with controls for rate control, quarantine, and tagging, and we can see whether an email is a spam email or a phishing email."
"The solution is largely stable, it can scale, and overall it has been working fine without issue, while the message tracking and messaging logs have proven to be quite useful."
"The primary use case of this solution is to filter emails and only allow the legitimate ones through."
"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."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"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."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"The most valuable feature is the straightforward setup."
"The most valuable features are the anti-phishing and anti-spam capabilities."
 

Cons

"Some customers experience issues with integration."
"There is room for further integration with the wider platform."
"Few customers require an on-premises fabric ATP box for attack detection and response."
"The DMARC security is somewhat weak and could be strengthened."
"My customers were sending OPT bulk emails and Barracuda Email Security Gateway was not able to handle it. We have to go with another different solution, such FortiMail for the task. We are implementing these combinations of the Barracuda and FortiGate, for email security. The FortiGate FortiMail security gateway we use to send only the bulk email, not for receiving emails."
"The user interface needs to be more responsive."
"The solution should add automatic alerts to the mobile."
"We cannot customize the solution according to our needs and, consequently, its reporting capabilities are lacking."
"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."
"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."
"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."
"Kaspersky lacks in the area of customization, so simpler customization options need to be provided to users."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
 

Pricing and Cost Advice

"Compared to other products, this solution is quite affordable."
"For overall value and cost, Barracuda came in as most appropriate, price as well as services provided. In terms of price, it's average . It's not the most expensive, it's not the least expensive but it works well."
"The price of this solution is very high, but it's working fine."
"We are using the trial version right now, and before purchasing the license, we need to solve some of the issues that we are facing. We need a proper solution for our email, and then we will look into pricing. We have a vendor for licensing."
"Barracuda Email Security Gateway is a cost-effective solution."
"The regular pricing was initially very reasonable, but three years ago, Barracuda revised their price list and SKUs, resulting in a significant doubling of the standard prices."
"I rate the price of Barracuda Email Security Gateway a ten on a scale of one to ten, where one is low price and ten is high price."
"There is an annual license required for this solution."
"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."
"The solution is not expensive."
"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."
