LeeMiles - PeerSpot reviewer
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.
LARK IT - PeerSpot reviewer
Easy to setup, stable and highly scalable
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. In future releases, I would just like to see that ability for users to see what's being quarantined and what's not quarantined but safe. Just those genuine false positives.

Quotes from Members

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

Pros

"The solution's most valuable feature is impersonation detection."
"I'm quite satisfied with the graphical user interface for Barracuda products."
"The product is easy to deploy and maintain."
"The most valuable aspect includes attempts to spoof or compromise domains from external sources."
"We check the reports sometimes to see that frequent attacks and malicious emails are being blocked by the solution."
"The most valuable features are security and ease of use."
"I would rate the solution nine out of ten."
"The archiving and search features are very good."
"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

"The solution's graphical user interface (GUI) could be improved visually."
"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 policies are set up in Barracuda by default; we don't have any control over them."
"I would like to see better integration with other products."
"Sometimes it is somewhat laggy, especially on the Archiver side. It should have improved performance on their Message Archiver."
"They could simplify the licensing and the pricing."
"The product must enable bulk user management."
"There is room for improvement, particularly in reaching out to technical support during deployment."
"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."
