Robust email protection with advanced features such as effective spam filtering, virus and malware defense, phishing protection and high scalability
Our customer faced a significant challenge with spam, leading to increased expenses. The complexity of their email infrastructure added to the issue, with some clients using Microsoft Exchange, others relying on different systems, and some operating on Linux platforms. To address this, we…
John Zupancic - PeerSpot reviewer
Inexpensive, with good email security, but the technical support could be improved
We don't have as many problems with email security. They have some areas that could be improved. For example, we also use this solution for email encryption, which was clunky and could be improved, but the email security itself has been excellent. The web interface works well but the Outlook plug-in has been problematic. We've had to uninstall/reinstall it. On some Outlook clients (including mine), it causes Outlook to stop responding. I disabled the Outlook plug-in and only use the web interface.

Quotes from Members

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

Pros

"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."
"It not only tackles spam effectively but also incorporates advanced features like ATP and active features which ensures a comprehensive and adaptable email security solution tailored to their heterogeneous environment."
"The solution is scalable."
"Its backups are valuable."
"It's easy to use. The configuration and web interface are user-friendly."
"The most valuable feature is the Antispam services, which are the basic services of spam device"
"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."
"They do a better job of determining what's real and what's not than most of the other solutions we have tried, and it's been very painless to use."
 

Cons

"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."
"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."
"The deep scanning feature needs to be improved."
"Its integration with other solutions can be improved. There should be integration for telemetry information, system information, and other types of information with other solutions. Barracuda currently doesn't have that. Barracuda has its own platform. Its integration with firewalls is quite good, and it communicates really well with firewalls, but I have not seen any other integration. Based on what I know, it does have an API at the backend, but I have not used it."
"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."
"Barracuda Email Security Gateway can improve email detection. We have some emails that are bypassing the threat scanning. There are some impersonation emails passing through."
"The solution should include an improvised anti-phishing feature, since it blocks certain genuine emails."
"The pricing needs improvement."
"They have some areas that could be improved. For example, we also use this solution for email encryption, which was clunky and could be improved, but the email security itself has been excellent."
 

Pricing and Cost Advice

"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 price of the solution should be reduced. The price in the USA is less than where we are. Our local distributor of the solution is manipulating the market."
"The licensing fees are part of a bundled support package that we pay for."
"The price of this solution is very high, but it's working fine."
"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."
