API-based email security software
Protect inbound, internal, email through a direct API connection to Microsoft 365 and Google Workspace, standalone or alongside your SEG.

Your perimeter only gets one look at every message
A tool sitting in front of the mail flow inspects once, before delivery, and never sees internal or mail at all.
One pass, before delivery
A gateway judges a message once, on the way in. There's no way to act if new information surfaces after it's already delivered.
Blind to internal mail
Most gateways only watch inbound traffic, so a compromised account sending internally or moving data out goes unseen.
Manual triage overload
User reported messages pile up faster than analysts can clear them, and most turn out to be clean once someone finally looks.
API vs. SEG vs. layered email security
Benefits of API-based email security
Coverage that adapts in hours
When a new attack pattern surfaces in your environment, ADÉ (Autonomous Detection Engineer) generates, backtests, and deploys new detections before the campaign scales. You're not waiting on a vendor queue - you're covered before the next wave hits.

Transparent detection logic
Every verdict traces to a specific signal and the exact email content that triggered it. When a legitimate financial aid notification gets flagged, you resolve it in minutes - not weeks or months with a vendor ticket.
Abuse mailbox on autopilot
ASA (Autonomous Security Analyst) triages every user-reported email in seconds - investigating, resolving, and escalating only what needs human judgment. Your analysts stop working through a queue of submissions, saving hours of work every day.
Zero disruption to mail flow
Sublime connects via API to Microsoft 365 and Google Workspace. No MX changes, no SPF/DMARC reconfiguration. If Sublime goes offline, mail flow continues unaffected.
Why organizations choose Sublime Security for API-based email security
Sublime's distributed detection model adapts coverage to your environment and generates new defenses in hours.
Every verdict traces back to specific, readable detection logic. Security teams see exactly why a message was flagged, and write their own detection logic when they want to close a gap their way, without filing a vendor ticket.

Sublime deploys as a standalone API-based platform or alongside an existing SEG, and integrates with the SIEM, SOAR, and Slack workflows a security team already runs.
ASA (Autonomous Security Analyst) triages reported and suspicious messages in seconds, clearing the abuse mailbox queue automatically so analysts spend time on investigations, not inbox management.
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.

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.
JJ Agha
CISO, Fanduel
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.
Jason Kikta
CISO, Automox
With Sublime, we no longer wait weeks for vendor updates. Our team reacts instantly - which is critical for our fast-moving environment.
