Improved email security has reduced spam, simplified encrypted mail, and strengthened user trust
The best features Barracuda Email Protection offers include good spam filtering and very good sandboxing of all links, as well as good encryption. It also has integrated logging for user management of their own spam. It has better filtering technology, so few are false positives as well, with excellent anti-spam engines and logging. It is extremely easy to install, configure, and set up, and there is excellent message tracking for folks that say they have not received an email they were expecting. Integrated logging and user management make my daily work easier because it is very easy to log in and to manage this tool, hence making it a very good tool for email protection. It also has excellent, easy-to-add designated users as site administrators, and it is competitively priced. It has a user-friendly portal, strong cloud-based features, and no additional maintenance cost, along with responsive support. Barracuda Email Protection has positively impacted my organization by handling encryption better than any other tool I have used before, which has increased our email protection significantly. Our security has also increased from forty percent to sixty-five percent, especially when dealing with all the threats that come through emails. It has been a great tool because we can handle email delays and delays on file scanning. When our partners are happy, we are very happy, and it has helped us have less time chasing bad emails. The fast implementation of encrypted mail keeps employees working with less interruption since they are happy, satisfied, and secure.

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.

Quotes from Members

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

Pros

"I don't see any other email security solution that stacks up against them."
"The investment in Barracuda Email Protection is quite good for us because we see the value of money on it, as we are saving a lot with Barracuda Email Protection, going from paying close to 300,000 to now sitting at 100,000."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"I would rate the solution nine out of ten."
"The most valuable features of Barracuda Email Protection are flexibility and customization."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"With Barracuda Email Protection, the features I find most valuable are spam filtering, as it is primarily used for spam protection."
"The most valuable feature is the gateway."
"The most valuable features are the anti-phishing and anti-spam capabilities."
"We have achieved cost savings of up to thirty percent by using Kaspersky Security for Mail Server."
"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."
"Kaspersky Security for Mail Server provides protection against email spams and blacklisted emails which are suspicious, making it a good product."
"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."
"The most valuable feature is the straightforward setup."
 

Cons

"The solution's reporting mechanism is a little poor and could be improved."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"Customers chose a different product after experiencing a problem when they upgraded the firmware, which caused the system to restart multiple times during working hours."
"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."
"Barracuda Email Protection can be improved by enhancing the reporting feature."
"The licensing and pricing need to be improved."
"Regarding the price, I find it pretty expensive. It is not even reasonable; it is pretty expensive because we are dealing with the South African market and our currency is not as powerful as the dollar."
"The product must enable bulk user management."
"Sometimes Sophos has the patch to block a novel threat, but Kaspersky doesn't."
"The solution is not 100 percent stable and that can use improvement."
"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."
"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."
"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."

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

"The solution is not expensive."
"Price-wise, I would rate this product a four out of five. It could be a bit cheaper."
