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.

Cons

"False positives have given us issues."
"I have noticed that it takes a little time to get familiar with after deploying and some tweaks need to be done as things come up."
"We had an incident where we didn't want to receive any emails or spam from a certain site and email address. We selected the mail ID, and we send it to Barracuda for analysis to see if it's spam or something like that. As of now, we haven't gotten any update or notification as to what happened with it."
"The reporting can be improved."
"There's a bit of configuration work that's needed with the DNS service provider, but other than that, everything else should be very smooth."
"The pricing needs improvement."
"Barracuda's spam database isn't on par with its competitors. Users complain about the spam email they're receiving, and we report the issue. Barracuda said they are going to update their system to block the malicious email we received, but we're still getting the same spam. The signatures are not in their database. They need to update their spam signatures because spam is bypassing Barracuda."
"There is room for improvement in the management of multiple domains."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"We discussed the phishing aspect, the DNS system, and the key rotation."

"The installation is not so straightforward."
"The solution is very expensive."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"They should improve the cookies management feature."
