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

"With the cloud service, one of the nice things about Barracuda is the quarantine service. It gives the ability for our users to go in and check what has been quarantined, and then connect with our IT staff to release anything that should be fine so that we can test it before we release."
"The client has the option to blacklist or whitelist any email address or domain based on the sender and recipient filters. If they want, they can restrict any IP addresses so email won't be received from those IP addresses."
"The most valuable feature is the Antispam services, which are the basic services of a spam device."
"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."
"Barracuda is good at keeping the garbage from reaching your inbox."
"It catches a lot of things and has the ability to add domains as well as add senders and update their things."
"Customer support is the solution's strongest point."
"Barracuda is robust and I would say it is pretty stable."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"With both of them working together, we have the perfect solution for mail."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"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."
"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."
 

Cons

"Barracuda Email Security Gateway should add auto-remediation to improve the solution. Additionally, there are times when we have false positives and our general emails get locked, we have mentioned this to Barracuda."
"The solution could improve by adding DomainKeys (DKIM) functionality. This is something that is essentially required nowadays for outbound security. They do not have it on their on-premise solution appliance but they have alternate arrangements for their cloud solution."
"I had some difficulty in the past with the system getting swamped and overwhelmed trying to process all incoming traffic."
"We would like to have a local support center in India so that they are operating in the same time zone and speak the same language."
"The solution should include an improvised anti-phishing feature, since it blocks certain genuine emails."
"There is room for further integration with the wider platform."
"The pricing of this solution could be improved."
"Barracuda Email Security Gateway can improve email detection. We have some emails that are bypassing the threat scanning and there are some impersonation emails passing through."
"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."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"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."
"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."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"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."
 

Pricing and Cost Advice

"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."

"We pay between $8 and $10 USD per user per month."
