Remove the risk of bad clicks with automated email security

Ensure that user-reported emails are handled quickly and accurately.

Automatically close the loop

After a recipient reports a suspicious message, they’re automatically notified when the message has been triaged and classified.

Autonomous triage

ASA, our AI-powered Autonomous Security Analyst, fully automates triage and remediation of user-reported emails.

Self-healing coverage

ADÉ, our Autonomous Detection Engineer, takes ASAs results and creates new detections to close coverage gaps for novel attacks.

Sublime is one of those tools that just works. Everyone's a winner. Employees are happy their emails work, InfoSec has less operational burden, it requires little management, and the tool is nice to use.

Agentic email security from Sublime

Streamline responses to user reports with autonomous, AI-powered analysis, triage, and coverage.

Autonomous Security Analyst

ASA uses the same threat indicators, primitives, and TTPs that a human analyst would to make decisions – only faster.

Autonomous Detection Engineer

ADÉ takes results from ASA and creates new coverage, so you don’t have to. After a detection has been autonomously written, backtested, iterated upon, and finalized, a human analyst is notified for final review before it’s added to your instance of Sublime.

Automate busy work, focus on what matters

Sublime’s abuse mailbox automation lets analysts spend less time in triage.

Automate replies and verdicts

With Sublime's AI agents and automatic responses for user reports, teams can automatically interact with and give feedback to end-users.

Increase security for high-value targets

Executives and other high-value targets get extra protection, including custom alerts via API and webhooks.

Herd immunity with automatic quarantine

Sublime automatically quarantines new messages that match previous user reports by grouping similar content.

Track and report on trends

Abuse mailbox dashboards help security teams identify gaps that need to be filled with updated detections, handling, or user training.

Seamless SOC integration

Integrate seamlessly with existing SOC workflows and SIEM platforms.

What our customers are saying

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.
