Evolve beyond the vendor black box

Transparent detections

See exactly what matched and why. Inspect, audit, and trust every verdict.

Coverage that adapts

AI agents can author, test, and deploy new detections in hours or days as attacker tactics change.

No waiting on vendor queues 

Deploy and tune org specific detections without support tickets or release cycle bottlenecks.

Move beyond Abnormal

Sublime
Decentralized detection model (DDM)
Sublime’s detection model is defined by the customer’s environment, so coverage adapts to your org instead of relying on one vendor-defined baseline.
Transparency you can act on
See the detection logic behind alerts so teams can validate outcomes, audit decisions, and tune coverage when business context changes.
Adapts at adversary speed
When attacker tactics shift, teams need coverage that can evolve quickly. Sublime is built to close gaps fast in the customer environment.
A team of AI agents to eliminate extra work
Automation is a core part of the product: reduce time spent on repetitive triage and operational busywork so analysts can focus on real investigations.
Abnormal
Centralized detection model (CDM)
Abnormal is primarily vendor-defined: you receive detections packaged by the manufacturer, with less ability to directly shape what’s running in your environment.
Explainability after the fact
Emphasizing explanations after a verdict can help interpretation, but may not provide the same level of direct control over what’s matching.
Slower, vendor-dependent iteration
If change requires waiting on vendor cycles, teams can be exposed longer between “new tactic” and “new coverage.”
Narrower workflow automation
Some automation is limited to specific inboxes or user-reported workflows rather than end-to-end operational coverage.

How Sublime delivers better email security 

Sublime empowers security teams with tailored detections, explainable alerts, and automation - so you can prevent, detect, and respond to threats faster and with confidence.

Stop more attacks with fewer false positives

Block sophisticated threats like BEC and novel phishing with higher catch rates and fewer false positives.

Gain full visibility, automated updates, and control on demand

See exactly what was detected and why, then ADÉ refines for your environment, updating detections in hours instead of weeks.

Automate the abuse mailbox

ASA automates triage, investigation, and remediation of user-reported messages, cutting MTTR from hours to seconds and freeing your team.

Don’t take our word for it

The black box approach to email security no longer works. It reduces visibility on how Brex may be attacked and the tactics and techniques used by attackers. 



With Sublime, we now have transparency and the confidence to keep up with emerging threats.

The ability to automate remediations with high confidence and minimize manual reviews unlocks a new level of efficiency in our SOC. It’s hard to imagine going back to life before Sublime.

What I love about the platform is that it just works. I’m so tired of all these tools I have to futz with, and Sublime is just easy.
