Featured Reviews

Have raised concerns about scanning engines and automation while continuing to rely on layered protection strategies
Incident response is something that requires more development from Barracuda's side. Regarding room for improvement for Barracuda Forensics and Incident Response, for the product, developing or improving the scanning engine is important, but it's a bit tricky. I know that they are working on it heavily. The difference between Barracuda and Sophos is Sophos focused heavily on cybersecurity while Barracuda tried to increase their product portfolio. Sometimes, in some cases, this might end up with their teams being unfocused or a bit thin and stretched and super busy. However, there is room for improvement. The product is great. The teams that are supporting are great. But there is always room for improvement. Even if you have a product that you would give a rating of 10 out of 10, there is always room for improvement. The day we stop improving is the day we die. Regarding the scanning engine, Barracuda Forensics and Incident Response has a very good feature where you can create automated flows for how to handle specific emails that are detected as incidents. This needs a bit of an improvement. That's the only component of Barracuda Forensics and Incident Response that I believe requires improvement.

Experience high detection and user-friendly policies with reliable email security implementation
The system is not user-friendly because you have to create policies that are mapped in a dictionary. As an IT engineer, I understand how it works, but explaining it to another IT person can be difficult. Having more user-friendly dashboards would improve the work experience. In Mimecast Email Security, checking policies in the dictionary or gateway is very complicated, and not everyone understands this process. If you examine the Check Point portal, it's user-friendly with easily accessible tabs that anyone can explore. With Mimecast Email Security, making changes might impact existing mailboxes. The portal is complicated compared to Check Point's user-friendly interface.

Quotes from Members

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

Pros

"I would rate the solution nine out of ten."
"The most valuable aspect includes attempts to spoof or compromise domains from external sources."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"The archiving and search features are very good."
"The most helpful aspect for me is the out-of-the-box configuration, which is fairly good."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The solution's most valuable feature is impersonation detection."
"The product is easy to deploy and maintain."
"Due to our specialized use case, that HIPAA dictionary really comes in handy."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"The most valuable feature is the DMARC Analyzer."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"We like the content filtering and secure messaging features."
"The initial setup is easy."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"The setup was easy."
 

Cons

"Considering it integrates with Azure, I would like to be able to effectively set up policies where people are by default included in certain settings."
"The product must enable bulk user management."
"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."
"The solution's graphical user interface (GUI) could be improved visually."
"The customer service and support could be improved if the support were available directly in Europe. Currently, the support is often managed from India, so we sometimes need to wait due to the time zone difference. It would be quicker and better if the support were provided by European staff."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"They could simplify the licensing and the pricing."
"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."
"The feature that should be included is to remove the block on the encrypted files."
"The product's interface could be improved to be more user-friendly."
"The solution's console interface was recently changed for the admins, but the previous one was much better because we could open tabs on it."
"As a user, the user interface of the management console could be upgraded, for example."
"The system is not user-friendly because you have to create policies that are mapped in a dictionary."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"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."
 

Pricing and Cost Advice

"The solution's pricing is moderate, where it is neither cheap nor expensive."
"The product is expensive."
"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."
"Price-wise, this product is middle-of-the-road."
"The price is similar to that of Microsoft 365."
"We pay annually. They never charged us for anything else. And they were quite a bit under that $20,000 mark. It was $19,074. And they've been pretty good about not skyrocketing the price or anything like that. It has gone up. It's gone up to $24,000 in 2020."
"Barracuda licensing model is good."
"The price of Barracuda Essentials is better than some of the competing products."
"It is a bit expensive."
"The product has good pricing in terms of return on investment."
"The solution is expensive."
"The licensing costs are per-user for the product that you get with them."
"For what it is, the product is overpriced."
"I'm always going to say the price needs to be lower, but it's reasonable."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"The product price is moderate. I rate the pricing a five out of ten."
