Enterprise security. Built for what’s next.
ENGINEERING PERSPECTIVE

The next RBI evaluation belongs in the user’s workflow.

Rendering fidelity is only one part of browser usability. Input, accessibility, identity, and controlled data movement determine whether isolation works in daily use.

Rendering is an architectural choice

Skia supplies cross-platform 2D graphics capabilities, and CanvasKit exposes Skia through WebAssembly. These building blocks help explain the opportunity for faithful presentation in a browser-delivered experience. They do not by themselves define remote execution security or application compatibility. Skia graphics architectureCanvasKit and WebAssembly

Test the work people actually do

A fast-loading demonstration page can conceal problems in a spreadsheet editor, an international input method, a keyboard-only workflow, or a multi-tab identity redirect. Evaluate a complete task and its data policies: copying approved text, blocking a prohibited download, printing a permitted document, and recovering a disconnected session.

Network Vector Rendering changes the presentation path. It does not repeal network propagation time. Separate local input feedback from a remote application response, and measure the tail of the interaction distribution under realistic jitter and loss. That is how an experience claim becomes an operational decision.

Build an experience contract

  • Define representative tasks and the completion criteria.
  • Test text, fonts, zoom, accessibility, keyboard, and IME behavior.
  • Measure interaction latency by region and network condition.
  • Apply upload, download, and clipboard policies during the same tasks.
  • Correlate session issues with rendering, transport, and origin evidence.

Our RBI white paper connects these experience requirements to the NVR/Skia rendering path and the agentic auditor’s investigation context.
