Instantly blocked and reduced our spam emails
The solution has to improve in a very specific way. When we allow our customers to send or scan email through our Barracuda Email Security Gateway, we are permitting their email server IP address, but not any domain. One of our customers has an email server where they are hosting five domains within their server. They are sending and receiving email through that server by using Barracuda Email Security Gateway. Therefore, we allow their IP address to send email through our Barracuda Email Security Gateway, then we declare MX for receiving email on behalf of our customers. After receiving the email, we deliver it to the specific IP address of the customer. Since we are only allowing the IP address, if an incident happens within a customer's email server or an email server gets compromised, then it starts sending spam. That creates a huge problem for the solution as it allows all emails because the customer's IP address is allowed to relay email through our Barracuda Email Security Gateway. 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.

It gives clients peace of mind and helps them educate their users about threats
A few years ago, our team found the implementation to be somewhat challenging. It has gotten easier as we've grown more experienced. The difficulty depends on the expertise of the person doing it. I don't work with Mimecast every day, so it might be more difficult for me than it is for one of my techs who regularly does Mimecast implementations. It requires some specific in-depth product knowledge and an understanding of email solutions. The deployment time varies. In South Africa, it depends on who you use to deploy it. If you use one of Mimecast's local partners, it can take up to two weeks because of their process. However, it's only about four to eight hours of work. After deployment, there isn't much maintenance aside from supporting and educating your customers. Users require constant education on how to use the Mimecast client and release an email that has been blocked.

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 Barracuda Email Security Gateway is that it blocks almost 99 percent of threats from users' email inboxes."
"We find the email security to be valuable."
"It can scale."
"The security protection is the best and it's GUI is user-friendly."
"We have found some of the valuable features to be how easy the solution is to configure, the graphic support, and the intuitive dashboard."
"I like Barracuda's cloud sandbox feature."
"Barracuda is good at keeping the garbage from reaching your inbox."
"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 interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"The most valuable feature is the DMARC Analyzer."
"The solution is scalable."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
"It's good, it keeps the spam out."
"I would rate Mimecast Email Security a nine out of ten."
"The solution offers good technical support."
 

Cons

"Barracuda should have a sandbox feature in the appliances."
"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."
"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."
"This product can always be made more secure."
"I am not aware of the licensing costs."
"The DMARC security is somewhat weak and could be strengthened."
"The dashboard's UI could be improved to make changes to the blocklist."
"Barracuda Email Security Gateway should add auto-remediation to improve the solution. Additionally, there are times when we have false positives and our general emails get locked, we have mentioned this to Barracuda."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"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."
"Its pricing can be improved. It is a bit expensive."
"Mimecast needs to reduce the number of false positive emails; a big pain point for us."
"The detection rates are an area for improvement."
"Many of our users complain that the system is blocking too many attachments. It's a good practice from a security perspective, but our users think Mimecast is doing too much. It might be something we'll have to adjust."
"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."
"The filtering needs more flexibility."
 

Pricing and Cost Advice

"This is one of the major points for integrating this solution in any organization. Barracuda Email Security Gateway needs to make it a bit more tolerable for customers because it is increasing every year. They should create a plan for reducing the cost."
"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."
"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."
"e solution's pricing is exceedingly high, and it continues to increase."
"We paid for an annual license."
"We find the solution's pricing okay."
"The licensing cost is competitive, it's not too high and not too low."
"Barracuda has the best price. Every year we need to renew our license, and every year I need to compare Barracuda to two or three other players in the market. Barracuda always has a price that is 30 to 40 percent less than the other players' prices."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"It's an expensive solution."
"There are additional costs beyond the standard licensing fee."
"I'm always going to say the price needs to be lower, but it's reasonable."
"It is a bit expensive."
"For what it is, the product is overpriced."
"The licensing costs are per-user for the product that you get with them."
"The solution is expensive."
