Very good threat protection, spam filtering, and cloud backups
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. For instance, for email quarantine, I can't set up a global setting. Users must go through an induction session where I guide them in configuring quarantine alerts rather than having default settings based on group membership. This seems like an oversight since they already use Active Directory details. They should assign policies based on group membership, which configures these settings by default.

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

"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 helpful aspect for me is the out-of-the-box configuration, which is fairly good."
"The archiving and search features are very good."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The best feature of Barracuda Email Protection is that it provides protection for Microsoft 365."
"When we got the service, it included the email archiver with unlimited storage."
"The beauty of Barracuda Email Protection is that it is easy to manage and simple to deploy."
"Barracuda email protection is stable. I would give it a nine because of its strong cybersecurity features."
"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."
 

Cons

"There is room for improvement, particularly in reaching out to technical support during deployment."
"The policies are set up in Barracuda by default; we don't have any control over them."
"The technology works on a supervised engine, but it would be better if it ran on an unsupervised engine."
"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."
"Two to three months back, we got fraudulent emails in which someone in the organization was being blamed."
"The platform's pricing needs improvement."
"The solution's graphical user interface (GUI) could be improved visually."
"I would like to see some additional functionality in terms of employee monitoring, as part of a work-from-home security solution."
"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."

"On a scale from one to ten, where one is cheap, and ten is expensive, I rate the solution's pricing a seven out of ten."

"The price is similar to that of Microsoft 365."
"The solution's pricing is moderate, where it is neither cheap nor expensive."
"Price-wise, this product is middle-of-the-road."
"I would rate the pricing of Sublime Security as a seven out of ten. It is reasonably well-priced."
