Stop data loss before it happens, without rigid rules or manual labels.
Secure outbound mail without relying on rules and manual labels, with the industry’s first label-free behavioral DLP with a proprietary DSLM.
As a business, data is your most valuable asset — and a breach comes at a high cost.
Darktrace / EMAIL – DLP protects sensitive data by understanding behavior and context — not just content
Our AI-driven approach combines behavioral and content analysis to detect and prevent data loss in real time, without the complexity of manual classification.

Protect everything, not just what’s labeled
Automatically identifies 35+ sensitive data categories, including personal, financial, and health data.
Detects labeled and unlabeled data, going beyond static regex to adapt to evolving data patterns.
Correlates outbound anomalies with account behavior and inbound intelligence to identify potential exfiltration, compromised accounts, or insider misuse before data leaves your organization.

Take immediate, precise action on data exposure
Analyzes recipient context and user behavior to catch accidental sends and warn employees in real time. Powered by a domain-specific language model that understands entities, PII patterns, and message context to prevent data leakage on-send.
Maps detections to a proven response flow:
- Contain: Hold or apply conditional access
- Assess: Review anomaly score and AI Narrative
- Resolve: Allow with justification or escalate to SOC
- Educate: Notify user or trigger micro-training
Responses can be fully customized via Action Flows and custom models.

Aligned with your SOC. Empowering your users.
Explainable AI
Enhanced AI Narratives clearly explain why an email was flagged, giving SOC analysts transparency into detection logic.
In-time feedback & education
Delivers contextual warnings and micro-training directly at the point of send, turning every detection into a learning opportunity while maintaining productivity.
Fast, low-friction deployment
Deploy quickly using a mail flow rule and connectors. No complex configuration, fingerprinting, or regex tuning required. Operational within hours, not weeks.
