Sublime Security

Sublime Security is a cybersecurity company that provides an email security platform focused on detecting and responding to targeted and evasive email threats through detection engineering and open, programmable controls.

• Detection engineering–centric email security platform (email security)
• Rule-based, programmable detection engine for custom threat logic (security analytics)
• Workflow automation for email threat triage and response (SOAR/email incident response)
• APIs, integrations, and event streaming for Security Operations (SecOps) tooling (security operations)
• Community-driven and open detection content for phishing and abuse use cases (threat detection content)

More About Sublime Security

Sublime Security focuses on email security for organizations that require customizable detection logic, visibility, and integration into existing SecOps workflows. Its platform is built around a detection engineering model that allows security teams to express email threat detections as code, rather than relying only on fixed vendor-defined logic. This positions Sublime Security in enterprise environments where teams want to tune detections to their own threat models, business context, and risk tolerance.

The company’s core offering can be categorized as an email security platform (email security) and SecOps tooling (security operations), with capabilities that overlap security analytics and automation (SOAR). The detection engine evaluates email characteristics across headers, body content, attachments, authentication results, sender reputation, and behavioral patterns to identify phishing, Business Email Compromise (BEC), spam, and abuse-related threats. Detection-as-code rules allow correlation of multiple attributes and conditions, enabling granular, transparent logic instead of opaque scoring models.

Sublime Security exposes detections, alerts, and events through APIs and integrations (security integrations) so that enterprises can route data into Security Information and Event Management (SIEM), Security Orchestration Automation Response (SOAR), case management, or data lake systems. This facilitates centralized visibility and enables incident response teams to orchestrate containment workflows such as quarantining messages, tagging emails, or triggering user notifications. Event streaming and webhooks support near real-time processing by downstream security tools, aligning Sublime Security with architectures where email telemetry is treated as another structured security data source.

The platform supports detection content that can be shared and reused, including rules for common phishing and abuse techniques. This content is designed to be inspected, versioned, and adapted, which fits workflows used by detection engineering and threat research teams. By treating email detections as code, Sublime Security aligns with practices familiar from Infrastructure-as-Code (IaC) and security-as-code, including concepts such as code review, testing, and collaborative development.

In the enterprise marketplace, Sublime Security is generally categorized under email security, phishing protection, and SecOps enablement. It is positioned as a complement or alternative to traditional secure email gateway and cloud email security tools, particularly for organizations that want direct control over detection logic and deeper integration of email telemetry into security analytics pipelines. Its focus on programmability and open detection content aims to support security teams that maintain internal detection engineering practices and require consistent workflows across email and other security domains.
