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

"The most valuable feature of the Barracuda Email Security Gateway is the ATP."
"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 link protection and anti-phishing features are great."
"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."
"This appliance has helped in that we now eliminate the thousands of scams, spam, and malware emails that are destined for our users."
"The most valuable feature of Barracuda Email Security Gateway is that it blocks almost 99 percent of threats from users' email inboxes."
"Barracuda is good at keeping the garbage from reaching your inbox."
"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 setup was easy."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"The solution is scalable."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The most valuable feature is the DMARC Analyzer."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"It offers an easy initial setup."
 

Cons

"The reports are standard, and it would be nice to be able to customize them."
"Barracuda Email Security Gateway can improve reporting and anti-spam. The anti-spam engine is not working well. We are seeing a lot of problems where spam is going through the gateway. Additionally, access privilege should be given to the IT support, because they don't have a lot of privileges. We are forced to give our IT support administrative access in order to clear and deliver emails and this should not be happening."
"Two improvements that are needed include an enhancement in the proxy feature, as well as the ability to more fully automate patches and updates."
"The pricing needs improvement."
"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."
"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."
"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."
"There is room for improvement in the management of multiple domains."
"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."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"The attachment scanning feature doesn't work properly."
"The installation is not so straightforward."
"The price could be better, it should be reduced."
"The product's interface could be improved to be more user-friendly."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"Its pricing can be improved. It is a bit expensive."
 

Pricing and Cost Advice

"Compared to other products, this solution is quite affordable."
"We pay between $8 and $10 USD per user per month."
"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."
"There is an annual license required for this solution."
"The price of this solution is very high, but it's working fine."
"The price of Barracuda Email Security Gateway is approximately $17 per user annually."
"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."
"It's an expensive solution."
"The licensing costs are per-user for the product that you get with them."
"The product price is moderate. I rate the pricing a five out of ten."
"The customers can select the license packages as per their requirements."
"The product has good pricing in terms of return on investment."
"There are additional costs beyond the standard licensing fee."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"We pay monthly fees to our provider."
