Browser Layer

Trust decisions at the browser edge

Evaluate trust signals directly within the browsing context. Privacy-safe local inspection surfaces explainable decisions before people interact.

Architecture & Flow

How the Browser Layer works

Local intelligence that sits between user intent and third-party execution.

  1. Intercept

    The Browser Layer captures navigation and request signals at the extension boundary before the destination loads.

  2. Collect

    Validated signal providers gather relevant DNS, certificate, domain-age, and reputation observations.

  3. Evaluate

    The Qeris Trust Engine evaluates canonical evidence against a versioned policy and returns a structured decision.

  4. Display

    The decision and its reasons are rendered inline, giving the user context before they continue.
