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

"The solution is scalable."
"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."
"Barracuda Email Security Gateway has positively impacted my organization by reducing security incidents and stopping attacks targeting us."
"This solution has helped to significantly reduce the amount of junk email that we receive."
"It is lightweight, and we can filter all of our inbound and outbound emails. We have controls for rate control, quarantine, and tagging. We can see whether an email is a spam email or a phishing email."
"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."
"Eliminating inbox clutter creates an opportunity to be more productive instead of wasting time manually sorting through spam."
"The most important features of Barracuda Email Security Gateway are the simple and quick configuration, interactive console, and easy-to-understand logs."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"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 most valuable feature is the straightforward setup."
"I find the product valuable because it provides easy integration with other platforms like Fortinet firewalls."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"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

"The solution should add automatic alerts to the mobile."
"There is room for improvement in the management of multiple domains."
"Barracuda should add an option where it can add multiple domains, such as abc.com, bbc.com, and cbc.com. Therefore, this 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 domain's emails will be relayed through Barracuda Email Security Gateway. That is the drawback that I have observed. So, Barracuda should work on this."
"Few customers require an on-premises fabric ATP box for attack detection and response."
"There are some times when legit emails are trapped on Barracuda and we are unable to get that information unless we actually log on to the network to find out."
"I would like to have better integration with third-party archival vendors to facilitate moving data in and out."
"Barracuda's spam database isn't on par with its competitors. Users complain about the spam email they're receiving, and we report the issue. Barracuda said they are going to update their system to block the malicious email we received, but we're still getting the same spam. The signatures are not in their database. They need to update their spam signatures because spam is bypassing Barracuda."
"The reports are standard, and it would be nice to be able to customize them."
"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."
"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."
"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."
"The solution is not 100 percent stable and that can use improvement."
 

Pricing and Cost Advice

"The pricing for the product is fine."
"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 solution requires a license and we pay annually."
"Compared to other products, this solution is quite affordable."
"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."
"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."
"Barracuda has the best price. Every year we need to renew our license, and every year I need to compare Barracuda to two or three other players in the market. Barracuda always has a price that is 30 to 40 percent less than the other players' prices."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
"My company makes annual payments towards the licensing costs solution."
"The solution is not expensive."
"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."
