Secret blocking

Blocks credentials and tokens under balanced policy.

PII redaction

Redacts emails, phones, DOBs, addresses, IDs, and health identifiers.

Team rollout

Invite-token enrollment connects browsers to the right team policy.

Product surface

One guardrail across browser prompts, team policy, and review.

PromptFence pairs a lightweight extension with a team dashboard, so owners can set policy and users can keep working without guessing what is safe to paste.

Operating model

Built for teams that want control without slowing work down.

Security workflow from detection to redaction, policy decision, and review
Detect

Detect before send

The extension scans prompt text locally, flags sensitive values, and shows the safest next action before data leaves the browser.

Decide

Apply team policy

Admins choose a preset, define sensitive terms, and decide whether users can send after warning or must redact first.

Review

Keep audit trails

PromptFence stores metadata, hashes, redacted samples, and decisions so teams can review usage without retaining raw prompts.

Detection coverage

Designed for the data people paste by accident.

The scanner combines structured patterns, context terms, entropy checks, validators, and team-defined phrases.
