PII detection

Detect sensitive data before it spreads.

PII detection answers the next question after intent: What sensitive data is present? It helps teams see when AI interactions involve personal information, secrets, or restricted material.

What sensitive data is present?

3LS gives operators a readable view of when prompts, tool inputs, and outputs include customer data, credentials, or other content that needs extra care.

Personal data

Highlight customer and employee information

Surface names, identifiers, and other personal information when people paste, upload, or transform sensitive material with AI.

Outcome: Reduced accidental exposure

Secrets and credentials

Catch the details that should not move further

Spot tokens, credentials, and similar material inside prompts, tool inputs, and outputs before they spread into the wrong place.

Outcome: Fewer high-impact mistakes

Restricted content

Recognize when business-sensitive material is involved

Bring attention to restricted records and internal material so teams can decide whether to continue, warn, or stop the interaction.

Outcome: Clearer data protection decisions

Operator view

Turn AI interactions into clear decisions

Give security teams a readable trail of what was detected, what it meant, and what action was taken.
