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

"There are plenty of features, such as sandboxing capabilities with zero threat protection. It has all the leading email security appliances compared to other solutions."
"The product safeguards user mail for gateway defense, data protection, business continuity, AI-based inbox defense, and automated threat detection and incident response."
"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 performance is good."
"Before this solution, we didn't have any separate feature for protecting our emails. We used to only have a firewall but now we have email security. It has a graphical interface and we can see the log every time. We can see that the performance is fine."
"The most important features of Barracuda Email Security Gateway are the simple and quick configuration, interactive console, and easy-to-understand logs."
"The most valuable feature is the Antispam services, which are the basic services of a spam device."
"The security protection is the best and it's GUI is user-friendly."
"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."
"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 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."
"The most valuable features are the anti-phishing and anti-spam capabilities."
 

Cons

"Sometimes the spam filtering is a little too aggressive. You can not get granular enough to back off what is considered spam and what is not."
"The downsides of the solution stem from the fact that it is an expensive product, and one may see too many false positives when using it, making them both areas where improvements are required."
"Barracuda should add an option where it can add multiple domains, such as abc.com, bbc.com, and cbc.com; therefore, only these domains' emails will be allowed and other domains' emails will not be relayed through Barracuda Email Security Gateway, whereas if you allow the IP address, then any of the domains' emails will be relayed through Barracuda Email Security Gateway; that is the drawback that I have observed, so Barracuda should work on this."
"The dashboard's UI could be improved to make changes to the blocklist."
"Barracuda has shown difficulty in providing us with the solutions we sought."
"Some of the exposed emails were not blocked by our Barracuda clients."
"It's not a scalable product. If we want to scale it then we have to change the device, because it is on-premises."
"Some customers experience issues with integration."
"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."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The stability of Kaspersky Security for Mail Server is okay, not so much of an issue."
"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."
"Encrypted email attachments are not being monitored by this solution, which is an area that they need to work on."
"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."
 

Pricing and Cost Advice

"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."
"It is a cost-effective and relatively cheap solution as compared to others. Our customers have a yearly subscription. We do have a few customers with monthly subscriptions, but they have cloud-based Email protection, which is a different type of solution. Both solutions are very good."
"We paid for an annual license."
"e solution's pricing is exceedingly high, and it continues to increase."
"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."
"There is an annual license required for this solution."
"It is an expensive solution and I would rate it 5 out of 10."
"The solution is priced low. We have received a good price discount here in Sri Lanka. There are additional licenses we have to purchase a license for the ATP."
"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."
