Sublime Security
AI-powered email security with transparent detection rules that stop BEC, phishing, and advanced threats.
Visit websiteAbout Sublime Security
Sublime Security is a modern email detection and response platform that combines large language models with a transparent, programmable detection engine (MQL) to stop business email compromise, credential phishing, and emerging email threats.
Unlike legacy secure email gateways, Sublime gives security teams full visibility into why a message was flagged and lets them tune detections without waiting on a vendor.
Sublime Security use cases
Sublime Security is an AI-powered, adaptive email security platform. These use cases mirror Sublime's own published 'By use case' navigation, covering inbound protection, abuse mailbox automation, behavioural threat hunting, and email-focused detection and response.
Inbound Email Security
Preventing advanced inbound email threats using detection logic that adapts to an organisation's own environment rather than relying solely on static signatures.
Read the use caseAbuse Mailbox Automation
Automating the triage, investigation, and response to user-reported emails using AI agents, cutting the manual workload on security teams.
Read the use caseBehavioral Threat Hunting
Giving security teams the tools to proactively search historical and live email data for threats that evaded initial detection.
Read the use caseM-SOAR
Automating detection, triage, investigation, and remediation of email-based threats to shorten response times and reduce analyst fatigue.

Where CyberLane Helps
Email remains a primary initial access vector. CyberLane helps clients evaluate where Sublime Security fits when they need high-fidelity detection of modern email threats with more transparency and control than a legacy gateway offers. We support requirements, architecture, business case, proof-of-concept planning and implementation oversight.
Product-specific delivery is coordinated with the vendor or qualified implementation partners.
Advisory topics Sublime Security is matched with
Technology decisions start with the advisory work, not the product. These are the domains where Sublime Security is typically considered — read the advisory approach before evaluating the technology.
Common questions about Sublime Security
Do we replace our secure email gateway?
Not necessarily. It commonly runs alongside Microsoft 365 or Google Workspace native controls, detecting what those miss; whether a legacy gateway can then be retired is part of the evaluation.
Why does rule transparency matter?
Security teams can see exactly why a message was flagged and tune detections themselves, instead of raising a ticket and waiting for a vendor model update.
Does it handle AI-generated phishing and BEC?
Those are the primary use cases. Detection combines language models with behavioural and infrastructure signals, because well-written AI-authored mail no longer fails on grammar or formatting.
What is the operational overhead?
Meaningful only if nobody owns detection tuning. Most value comes from pairing it with automated triage and a clear response workflow.
How does CyberLane get involved?
We frame the email-risk problem, define detection and response requirements, plan the proof of concept and oversee implementation with the vendor or a delivery partner.
