It offers effective protection for email data by using autonomous AI agents to detect phishing, malware, and cyber attacks.
Sublime Security integrates seamlessly via API, allowing users to monitor email threats effectively.
It enhances security by adding a smarter detection layer that complements existing protections like Microsoft 365 and Google Workspace.

CONS

Sublime Security requires optimization for better performance.
Scalability is limited, but it may improve in the future as a unique approach to email security.
There are many false positives, leading to significant administrative overhead.
End-user quarantine viewing is inadequate since it restricts visibility to back-end users only.
A steep learning curve hinders usability as it is not a plug-and-play solution.

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.

This is why it provides absolute value; it adds a smarter layer that catches anything missed by Microsoft 365 or Google Workspace protection, as attackers can breach those systems easily using flexible detection logic that security teams can quickly customize.

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.

To improve Sublime Security, I think the learning curve is the primary concern; it is powerful, but it is not plug and play.

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.
