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.

Effective threat protection with room for cost and usability improvements
There are some drawbacks that I would mention. To be frank, enterprises always look for cost benefits, so Kaspersky could implement some price benefits. Additionally, regarding know-how, if I am an experienced person it's fine, but when someone novice is working with it, they need information about why certain actions are required. Security is a field that is very vast, and implications are not known to everyone. In future updates, a quick walk-through and know-how features would be beneficial, such as information text at relevant places. This will increase usability. Feature-wise, an impact analysis would be a really good addition.

Quotes from Members

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

Pros

"The product safeguards user mail for gateway defense, data protection, business continuity, AI-based inbox defense, and automated threat detection and incident response."
"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."
"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 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."
"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 most valuable feature of the Barracuda Email Security Gateway is the cloud ATP functionality not available on the on-premise version. Most of the zero-day attacks can be mitigated with ATP. Additionally, the reporting functionality is good."
"The spam filtering, in particular, is very important for us. We have a large volume of emails each month, something like 200,000, and Barracuda filters about 85 percent of the spam, malware, and phishing that comes in. It prevents our users from receiving this content on their computers."
"Barracuda is good at keeping the garbage from reaching your inbox."
"When it comes to threat detection, it is very strict with file downloads and uploads. It sends reports and quarantines suspicious files."
"Kaspersky Security for Internet Gateway has positively impacted our organization by helping us control unwanted attacks and limiting our exposure to risks."
"The most valuable features of this solution are its ease of use and operation efficiency."
"The password thing is very good, and the overall URL protection."
"The most valuable feature of Kaspersky Security for Internet Gateway is the antivirus."
"The most valuable aspect for me is the user-friendly interface."
"The most valuable features of the solution are the antivirus and child protection features."
"I would recommend it to others as it's easy to use."
 

Cons

"The pricing is a little bit high, and it is causing the company to rethink renewal. If they could lower the pricing, that would be ideal."
"The pricing needs improvement."
"Two improvements that are needed include an enhancement in the proxy feature, as well as the ability to more fully automate patches and updates."
"Barracuda should have a sandbox feature in the appliances."
"The UI could be a little cleaner and require less clicking around in different modules. They give the illusion of a single pane of glass, but as you click around to different products, you're actually being transferred into a different system."
"Regarding real-time intelligent features of the Barracuda Email Security Gateway, some spam emails are still being released by the ESG to the end users, so the functionality is not working appropriately."
"Some of the phishing emails are not being blocked. Another problem is that we are not able to manage the date and time in our time zone."
"The dashboard's UI could be improved to make changes to the blocklist."
"It might be helpful to have notifications on mobile devices, especially if the same browser profile is used on both mobile and laptop."
"The initial setup of Kaspersky Security for Internet Gateway is complex. The full deployment took approximately two weeks."
"There is room for improvement in terms of the pricing."
"The customer support of the product is an area with shortcomings where improvements are required."
"I believe the absence of a procedure is the main issue."
"In different locations, they're priced differently, but that's mainly marketing rather than the product features."
"When I do a configuration, I do not know what implication it will have downstream."
 

Pricing and Cost Advice

"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"We typically purchase a one or three-year license for Barracuda Email Security Gateway."
"e solution's pricing is exceedingly high, and it continues to increase."
"The price of this solution is very high, but it's working fine."
"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."
"We find the solution's pricing okay."
"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."
"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."
"I rate the product's price an eight on a scale of one to ten, where one is very cheap, and ten is very expensive."
"Personal computer licenses can be expensive if you were to scale the solution extensively. However, large companies will most likely use Endpoint solutions and not this one."
"It is expensive."
"The cost is relatively high, and as a licensed product, there are restrictions on the number of users permitted per license."
"I am okay with the pricing."
"I would rate the pricing a seven out of ten, with ten being very expensive and one being cheap. It's neither too cheap nor too expensive."
