Platform

Four parts. One engine.

The extension enforces. The policy decides. The log proves. The dashboard reports.

Architecture

Read at the source. Keep it local. Govern the edges by policy.

The parts

Each one, and what it does not do.

Detection engine

Two layers. Twenty-one data types.

Sixteen by checksum. Four by a model on the device. One honest flag.

  • A checksum match always beats the model
  • Prompts and files, the same engine
  • No text layer: flagged, your policy decides

Policy engine

Working from the first hour.

Five actions. Four EU templates: GDPR baseline, Financial, Government, Education.

  • Built from department, data type, destination, channel
  • New rules simulate against live traffic first
  • Every version signed. Rollback is one click

Posture dashboard

The view a board can see.

Interactions, detections, blocks, shadow AI, a fourteen-day trend. By department, never by person.

  • No individual metric exists in the product
  • Unmasking needs a second approver and is logged
  • In works-council mode, it does not exist

AI gateway

The edges the browser can't reach.

Developer APIs, agents and sanctioned tools, on keys you issue.

  • Mistral and Azure OpenAI EU stay in the EU
  • OpenAI, Anthropic and DeepSeek can be blocked per department
  • Desktop apps are governed by a device blocklist, never by interception

Coverage

What we see. What we don't.

We say it in the product and in the contract.

No proxy. No root certificate. No kernel driver. No app hooking.

What we do not build

Each exclusion removes a risk.

No

Proxy or root certificate

Breaks on certificate pinning. Weakens the security it promises.

No

Kernel driver

One bad update can take a fleet down. Not ours.

No

Desktop app hooking

Desktop apps are governed by policy, not hooks.

No

Text recognition on scans

Scans are flagged, not read. The seam exists for later.

No

Productivity score

Never built. Nothing to switch off.

No

Content on our servers

Labels and hashes only. Nothing worth stealing.

Let's talk.

Thirty minutes. You watch the product stop realistic data in a real browser.

  • Six leaks: three prompts, three files, live
  • The dashboard a security lead sees on Monday
  • An evidence pack exported and verified while you watch
  • Whether a proof of value in your estate makes sense

We send what you type to one mailbox. Nothing else. See privacy.

Received. We reply within one business day.
