Mohammed Shah Newaj - PeerSpot reviewer
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

"It is lightweight, and we can filter all of our inbound and outbound emails. We have controls for rate control, quarantine, and tagging. We can see whether an email is a spam email or a phishing email."
"We have found some of the valuable features to be how easy the solution is to configure, the graphic support, and the intuitive dashboard."
"The most valuable feature of Barracuda Email Security Gateway is the complete capabilities it provides. Additionally, the phishing security and sandbox features are effective."
"The solution is scalable."
"The most valuable feature of the Barracuda Email Security Gateway is the ATP."
"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."
"One advantage is its immediate deployment capability. So the fast speed to deploy is a big plus point."
"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."
"In the current environment that the world is in, everyone is trying to hack everyone else, so Project+ definitely helps a lot there."
"Mimecast certainly helped my customers reduce phishing emails."
"URL inspection works pretty well."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"The initial setup is very straightforward."
"The biggest advantage of Mimecast Email Security is its spam filtering. Its filtering feature is interesting."
"I recommend Mimecast based on customer requirements and budget."
 

Cons

"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."
"I am not aware of the licensing costs."
"The solution should add automatic alerts to the mobile."
"I would like to have better integration with third-party archival vendors to facilitate moving data in and out."
"We would like to have a local support center in India so that they are operating in the same time zone and speak the same language."
"There are limited administration controls that should be improved."
"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 technical support is not available globally 24/7 and this is the biggest problem with the product."
"They should improve the cookies management feature."
"As a user, the user interface of the management console could be upgraded, for example."
"I'd like to have better support from the product in the future."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"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 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 solution is very expensive."
"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."
 

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 price of the solution should be reduced. The price in the USA is less than where we are. Our local distributor of the solution is manipulating the market."
"Our licensing fees are approximately $4,000 per year, and this includes updates for the antivirus and spam signatures."
"We typically purchase a one or three-year license for Barracuda Email Security Gateway."
"The solution requires a license and we pay annually."
"The licensing cost is competitive, it's not too high and not too low."
"As far as advanced email security systems, this product is mid-range on the pricing scale."
"Compared to other products, this solution is quite affordable."
"There are additional costs beyond the standard licensing fee."
"The product price is moderate. I rate the pricing a five out of ten."
"We pay monthly fees to our provider."
"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."
"For what it is, the product is overpriced."
"The product has good pricing in terms of return on investment."
"It's an expensive solution."
"The licensing costs are per-user for the product that you get with them."
