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.

I believe the main areas for improvement for Sublime Security are ease of onboarding and learning, as the platform has many powerful capabilities, making it take some time for new analysts to become comfortable with all the features and detection logic.

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

I would say there are very minimal changes needed regarding Sublime Security; for first-time users, it can be difficult knowing how to write the tool.

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.
