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

"The solution is straightforward to set up."
"The most valuable features are security and ease of use."
"The beauty of Barracuda Email Protection is that it is easy to manage and simple to deploy."
"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"We now have a secondary backup of Office 365 that's much easier to retrieve compared to Microsoft. If someone deletes something in Office 365, we can get it back within Office 365, but it's difficult. Barracuda is much easier. There is a lot less management needed using Barracuda. The management becomes much easier for Office 365 and it's no longer on-prem, so there are fewer hours managing on-prem devices, servers, and things of that nature. We don't have network appliances anymore for the backup of our information."
"The solution's most valuable feature is impersonation detection."
"The archiving and search features are very good."
"The most valuable feature is the DMARC Analyzer."
"We like the content filtering and secure messaging features."
"The initial setup is very straightforward."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
"URL inspection works pretty well."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"Based on overall experience, Mimecast Email Security is the best solution for traditional gateways."
"The piece that is most valuable from the Mimecast standpoint will be the sandboxing feature."
 

Cons

"The product must enable bulk user management."
"Barracuda Essentials can improve by continually adding more features."
"Barracuda Email Protection needs better reporting and more robust integration with security awareness training platforms and third-party solutions."
"Sometimes, in some cases, this might end up with their teams being unfocused or a bit thin and stretched and super busy."
"The solution's reporting mechanism is a little poor and could be improved."
"The policies are set up in Barracuda by default; we don't have any control over them."
"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."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"Mimecast Email Security is somewhat expensive compared to the competition in the Indian market, and the local presence is lacking as they do not have a local representative currently."
"The price could be better, it should be reduced."
"They could provide a unified licensing model, including all the security features."
"I'd like to have better support from the product in the future."
"The solution should include more AI features instead of Mimecast's more general static configuration tooling."
"The solution is very expensive."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"The solution is complex and not easy to use."
 

Pricing and Cost Advice

"Barracuda licensing model is good."
"The price of Barracuda Essentials is better than some of the competing products."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"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."
"The price is similar to that of Microsoft 365."
"Price-wise, this product is middle-of-the-road."
"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."
"We didn't have to pay a lot for the solution because we got it from a good vendor with a good user volume."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"The solution is expensive."
"I'm always going to say the price needs to be lower, but it's reasonable."
"For what it is, the product is overpriced."
"The product has good pricing in terms of return on investment."
"On a scale of one to ten, where one is cheap, and ten is expensive, I rate the pricing a ten."
"It's an expensive solution."
"The customers can select the license packages as per their requirements."
