Reliability dimension

Accessibility Testing

Ensure inclusive experiences while preventing compliance liability.

Accessibility validation ensures your application works for users with disabilities-screen reader compatibility, keyboard navigation, color contrast, ARIA implementation. Beyond compliance, it's about reaching 15% of the global population with disabilities.

Accessibility Reliability

What this validation covers

Structured capability coverage for teams that need repeatable signal instead of brittle scripts and one-off audits.

WCAG 2.1 AA/AAA compliance validation
Screen reader flow simulation
Keyboard navigation path analysis
Color contrast and visual hierarchy
Dynamic content accessibility

Why teams need it

Manual accessibility audits happen once per release-if at all. By the time an audit finds issues, they're baked into production. Remediation costs 10x more than prevention. Meanwhile, automated scanners only catch 30% of real accessibility barriers because they can't understand user journeys.

How Zof approaches it

The Accessibility Agent uses the System Graph to understand your application's user flows, not just individual elements. It simulates real screen reader interactions, validates keyboard navigation paths, and catches accessibility barriers in context-before code ships.

Failure modes it catches

Focus traps that block keyboard users

Dynamic content not announced to screen readers

Custom components missing ARIA implementation

Navigation sequences that break assistive technology

Form validation inaccessible to screen reader users

Color contrast failures in dark mode or branded sections

Business impact

Prevent ADA/Section 508 litigation

Reach 15% larger addressable market

Meet federal contract requirements

Eliminate expensive remediation sprints

Flexible pricing by maturity

Start with a focused validation program and expand to full enterprise orchestration as your reliability program grows.

01Verification Engine

What must be proven before this action can be trusted?

Zof combines deterministic tools, specialized verification systems, customer-defined checks, and approved AI models under one verification architecture, and selects the evidence each change requires.

DOMAINS

19 verification domains

From unit tests to stress, security, and compliance.

SELECTION

  • Change
  • graph
  • risk
  • policy

The right evidence, not every test every time.

SOURCES

Tools, systems, models

Deterministic first; AI reasoning where approved.
