Local-first browser protection

Stop secrets
before they leave.

Airlock inspects text only when you ask—right before it reaches an AI tool, support portal, form, or webhook.

01 — HOW IT WORKS

A deliberate pause
before “send.”

01

You choose when to inspect

Paste into the side panel or read the active field with a click. Airlock never watches every keystroke in the background.

02

Local detectors find the risk

Deterministic rules catch secrets and PII. Your own Ollama model can add context without sending text to a cloud LLM.

03

Redact, pseudonymize, or block

Review every finding, create a safe version, and put it back into the form without breaking your flow.

02 — PROTECTION LAYERS

Guardrails with
nothing to hide.

⌁

03 — ENTERPRISE EVENTS

Your logs.
Your boundary.

Airlock can send a signed, content-free event to an endpoint you control. Join it with your identity provider or device inventory without giving us a copy.

  • Organization user and device identifiers
  • Destination origin and policy decision
  • Detector category counts—not matched values
  • Versioned schema and unique event ID
{
  "schema": "airlock.audit.v1",
  "decision": "block",
  "destinationOrigin": "https://ai.example.com",
  "categories": { "api-key": 1 },
  "actor": {
    "userId": "u_1042",
