Accessibility Statement
We want everyone to be able to use this website, including people who rely on a keyboard, screen reader, magnification, voice control or reduced motion.
Last updated: November 6, 2026
Our standard
We build this website to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at Level AA. This statement describes how the site is built and tested, and where we know it falls short.
How the site is built
- Semantic HTML with one main heading per page, ordered headings, landmarks and a “skip to content” link.
- Menus, tabs, accordions, the multi-step assessment form and the interactive demonstrations all work with a keyboard and show a visible focus indicator.
- The main navigation follows the disclosure pattern: each button announces whether its menu is expanded, and Esc closes the menu and returns focus.
- Text and interface colors meet AA contrast ratios.
- Animation is subtle, never takes over scrolling, can be paused where it runs continuously and switches off when your system requests reduced motion.
- Form fields have visible labels, and errors are described in text and announced to assistive technology.
- Layouts adapt from large displays down to screens 320 pixels wide and support zoom to 400%.
Known limitations
- Interactive demonstrations. Some dense visualizations, such as network diagrams and dashboards, convey relationships visually. Text descriptions sit alongside them and the surrounding page explains the same process, but the experience is not identical for screen-reader users.
- Moving media. Some panels on the home page play muted background video. Video never plays when your device requests reduced motion, and it pauses when it scrolls out of view.
- Documents. Any downloadable documents we publish will be checked for accessibility first.
How we test
We check every page with automated tools, keyboard-only navigation, browser zoom and reduced-motion settings.
