Quotes from Members

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

Pros

"Barracuda Email Security Gateway is very simple to use."
"It can effectively combat phishing attacks, block spam, provide confirmation, and ensure operational manageability with a strong focus on product stability."
"The feature that sets Barracuda apart from other solutions is the Office 365 cloud-to-cloud backup."
"The most valuable feature is the Antispam services, which are the basic services of spam device"
"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."
"It is a very stable solution."
"The anti-spamming, anti-fishing features are great."
"Eliminating inbox clutter creates an opportunity to be more productive instead of wasting time manually sorting through spam."
"The feature I found most valuable was getting details on the emails, being alerted once those emails got a bad reputation, and then being able to take action on those emails."
 

Cons

"Barracuda has shown difficulty in providing us with the solutions we sought."
"Barracuda should have a sandbox feature in the appliances."
"We detect some failures in some mails; not all mails pass through consistently. Some mails pass while others are dropped without any apparent logic, despite having the policy set for specific recipients or senders."
"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 spam filtering is a little too aggressive. You can not get granular enough to back off on what is considered spam and what is not."
"The reports are standard, and it would be nice to be able to customize them."
"The dashboard's UI could be improved to make changes to the blocklist."
"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."
"This solution needs to improve the area of GUI as well as dashboards because they are very poor in terms of the current email security solution."

"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."
