Autonomous, AI-driven email security
Email remains the most common entry point for cyber attacks. Sophisticated phishing campaigns, business email compromise (BEC) and malware frequently bypass traditional email filtering technologies.
Sublime Security brings a new approach to email protection by combining advanced AI, detection engineering and automation to identify and stop sophisticated threats before they reach users.
As a Nomios partner, Sublime Security helps organisations strengthen their email security posture, gain full visibility into threats and respond faster to emerging attacks.
What is Sublime Security?
Sublime Security is a next-generation email security platform designed to prevent, detect and respond to modern email-borne threats. Built for cloud email environments such as Microsoft 365 and Google Workspace, the platform analyses email content, links, attachments and sender behaviour to identify sophisticated attacks that traditional tools often miss.
Unlike legacy email gateways or black-box AI tools, Sublime Security provides transparency and control over threat detection. Security teams can create custom detection logic, investigate incidents in detail and automate response workflows to reduce manual effort.
By combining AI-driven analysis with programmable detection capabilities, Sublime enables organisations to continuously adapt their email security to evolving threat techniques.
A Modern Approach to Stopping Advanced Email Threats
Designed for modern cloud email environments, Sublime provides security teams with full visibility into threats, the ability to create custom detections and the automation needed to respond quickly to incidents. This enables organisations to detect more threats, reduce manual investigation time and strengthen their overall email security posture.
AI-drive threat detection
- Sublime uses advanced AI models and behavioural analysis to detect phishing, impersonation and malware campaigns that bypass traditional email security controls.
Autonomous investigation and response
- AI agents automatically analyse suspicious emails, triage reported messages and remediate threats across the organisation - reducing the workload on security teams.
Transparent and explainable security
- Unlike black-box tools, Sublime provides full visibility into why an email was flagged, allowing analysts to validate threats and reduce false positives.
Custom detection engineering
- Security teams can build and deploy tailored detection rules using Sublime’s Message Query Language (MQL), enabling organisations to adapt protection to their specific threat landscape.
Cloud-native deployment
- Sublime integrates directly with Microsoft 365 and Google Workspace, enabling rapid deployment without complex infrastructure changes or email routing.
