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.

Improves decision-making with clear verdict explanations and works well across multiple environments
I know that a lot of time has been invested in improving the efficacy of the platform, and it shows; it performs very well. Moving forward, I think our focus should be on how to achieve better integration with other systems. While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value. This would allow it to be integrated more closely with the workflows of various teams and could potentially increase its market appeal. From my perspective, the tool itself functions exceptionally well, which gives me confidence in the system. I want to see this functionality extend to other tools that I use, enabling faster automation and improved workflows for the team, particularly from a security operations standpoint. I have no critiques regarding the tool itself. They've done an outstanding job and are maintaining high quality throughout their development process. They have a great product, and it's essential that they continue to uphold that standard, even though it requires significant effort.

Quotes from Members

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

Pros

"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."
"The beauty of Barracuda Email Protection is that it is easy to manage and simple to deploy."
"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 most valuable features of Barracuda Essentials are it's a trusted name and is rated very high on review sites. It blocks high percentages of spam and junk email and it's in the cloud. They have hardware appliances, but this is in the cloud. The solution is very effective at blocking malware and blocking spam and this is what we are looking for. There's not a whole lot of complexity, you want a solution that is very good at blocking out all of the unwanted emails."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"The solution's most valuable feature is impersonation detection."
"The most valuable features of Barracuda Email Protection are flexibility and customization."
"The most valuable features are security and ease of use."
"I like its ability to detect and block."
"Overall, the auditability and the ability to evaluate the information in Sublime through various mechanisms made me very comfortable with setting these capabilities to auto-remediation."
"So far, I do not see any problem with Sublime Security's support or their customer service."
 

Cons

"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"Sometimes, in some cases, this might end up with their teams being unfocused or a bit thin and stretched and super busy."
"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."
"The solution's reporting mechanism is a little poor and could be improved."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"There is room for improvement, particularly in reaching out to technical support during deployment."
"They could simplify the licensing and the pricing."
"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."
"While they do provide API-level access and web hooks, I believe more out-of-the-box integrations with SOAR platforms and SIEM tools would enhance Sublime's value."
"The ability for users to look at their own quarantine box needs improvement. So at the moment, it doesn't give you the ability to see every email that has been quarantined. No end-user has the ability to see what's being quarantined. It's only people who have access to the back-end platform that can actually see what has been quarantined. The end user doesn't know if they have an email that has been quarantined, only if they're expecting something that didn't come through."
"With Sublime Security, so far, I have seen a lot of false positives, and it is something that can bring a lot of administrative overhead."
 

Pricing and Cost Advice

"The product is expensive."
"The price of Barracuda Essentials is better than some of the competing products."
"Barracuda licensing model is good."
"Despite a list price possibly around $40 per user, their market price allows customers to easily buy the solution."
"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."
"Price-wise, this product is middle-of-the-road."
"The price is similar to that of Microsoft 365."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
