Prominent pros & cons

PROS

Users find no issues with Sublime Security's support or customer service.
Its ability to detect and block threats is highly appreciated.
The auditability and information evaluation mechanisms provide comfort in auto-remediation settings.
Sublime Security offers a smarter layer that enhances protection alongside Microsoft 365 or Google Workspace.
Flexible detection logic allows security teams to customize responses quickly.

CONS

Sublime Security has a high number of false positives, which can lead to administrative overhead.
The system lacks transparency for end-users to see what emails are quarantined.
Only back-end users can access quarantined email information, not end-users.
Integration with SOAR platforms and SIEM tools is limited, needing more out-of-the-box options.
Sublime Security's learning curve is steep, and it is not plug and play.

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.

The advice I give to others is that if you are looking for platforms that can safeguard your email data so you do not get any phishing emails, malware emails, or cyber attack emails, you can directly switch to Sublime Security because of its autonomous AI agents that can detect threats autonomously and the Microsoft 365 environments provided to save your data there.

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.

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.

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.
