Email security offers superior protection with good personalization
I have experienced the Barracuda team as very cooperative, and they are readily available for calls with technical support via email. I have had no issues with ongoing support throughout the product's lifecycle. Assistance was provided to me when transferring archived information from a legacy email service. They also recommended an additional service to streamline the process, making it as easy as possible.

Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.

Quotes from Members

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

Pros

"I appreciate that the product provides account takeover protection."
"The anti-spamming, anti-fishing features are great."
"It is very simple to whitelist 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."
"Barracuda Email Security Gateway has features like identify the spam source, rules to avoid some specific spams and then reschedule. And there are some other features like the email continuity, the email server and gateway site, which can relay the mail kit. The solution is user-friendly.These kind of features are the most valuable."
"The solution is scalable."
"One advantage is its immediate deployment capability. So the fast speed to deploy is a big plus point."
"Eliminating inbox clutter creates an opportunity to be more productive instead of wasting time manually sorting through spam."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"I would rate Mimecast Email Security a nine out of ten."
"The initial setup is very straightforward."
"The solution is scalable."
"Email security is the most valuable feature of the solution."
"The integration is straightforward."
"It offers an easy initial setup."
"Mimecast certainly helped my customers reduce phishing emails."
 

Cons

"Barracuda could improve its log and export options like PDF and HDML. It can also bring in more detailing in their console so that it could be better. Some new features should be expanded and made accessible for better protection."
"Sometimes there are false positive emails coming through, so they should improve further on detection technologies and techniques."
"There are limited administration controls that should be improved."
"The dashboard's UI could be improved to make changes to the blocklist."
"We still have critical threats coming into our environment and delivered to our users. When we compare it with other solutions, these other solutions can already detect those threats."
"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."
"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 reporting can be improved."
"The solution is very expensive."
"The installation is not so straightforward."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The tool can be challenging because it relies on rule-based configurations, especially for addressing impersonation threats. This approach requires setting up numerous rules to ensure filtering. It should work based on behavior-based analytics."
"Lately, Mimecast's outbound mail servers have been regularly blocklisted by spam filters. That didn't happen a few years back, but it seems to be a more frequent problem these days. When a server is blocklisted, it means all of my outgoing mail ends up in the recipient's junk mail. That affects my reputation and business confidence."
"The product's interface could be improved to be more user-friendly."
"The feature that should be included is to remove the block on the encrypted files."
 

Pricing and Cost Advice

"We pay between $8 and $10 USD per user per month."
"As far as advanced email security systems, this product is mid-range on the pricing scale."

"We paid for an annual license."
"Barracuda Email Security Gateway is an affordable solution that caters to small, midsize, and high-end businesses with great revenue."
"It is an expensive solution and I would rate it 5 out of 10."
"It is a cost-effective and relatively cheap solution as compared to others. Our customers have a yearly subscription. We do have a few customers with monthly subscriptions, but they have cloud-based Email protection, which is a different type of solution. Both solutions are very good."
"The licensing cost is competitive, it's not too high and not too low."
"The solution is expensive."
"Compared to the other products in the market, it is neither cheap but nor very expensive. I would rate it somewhere in the middle, 5 out of 10."
