OUTSIDE DEFENSE COUNSEL

The technical expert your defense can rely on

When an ADA accessibility claim turns on technical facts, your defense needs an expert who can establish them and defend them under scrutiny. Zenyth produces litigation-grade audits and expert testimony built to withstand cross-examination and discovery, from documentation that shows its methodology to declarations that rebut a plaintiff's expert. You get a technical partner who has done this before and will not come apart on the stand.

Qualifications built to withstand a Daubert challenge

Before you retain an expert or put one in front of your client, you need to know the qualifications will hold. Zenyth's accessibility experts bring formal certification, a documented decade of practice, and methodology built to withstand a Daubert challenge and cross-examination. This is the technical work your Americans with Disabilities Act (ADA) defense rests on, and it is built to be examined.

What Zenyth's experts bring

  • Formal certificationZenyth's testing is performed by specialists holding DHS Trusted Tester, IAAP Certified Professional in Accessibility Core Competencies (CPACC), and IAAP Accessible Document Specialist (ADS) certifications.
  • A decade of practiceTen years of hands-on accessibility work, including engagements as a retained expert witness, so the expert supporting your matter has done this work before.
  • Daubert-ready methodologyEvery opinion rests on a cited WCAG success criterion, a documented test method, and reproducible evidence, so the methodology itself withstands scrutiny, not just the conclusion.
  • Reports and declarations on the recordDefense counsel have retained Zenyth as a technical accessibility expert and submitted Zenyth's reports and expert declarations in ADA matters.

How a Zenyth audit is built

  1. Defined testing conditionsEvery audit documents the exact environments tested, the operating systems, browsers, and assistive technologies used, so results are tied to stated conditions rather than unspecified claims.
  2. Manual and automated testingAn automated first pass is paired with manual expert testing, including testing with assistive technology, because automated tools alone detect only a fraction of barriers. The methodology does not rest on a scan.
  3. Findings tied to standardEach finding cites the specific WCAG success criterion and conformance level it fails, with a severity rating and the affected user impact, so a conclusion is never separated from the standard behind it.
  4. Reproducible evidenceEvery finding is recorded with the page, the element, and screenshot evidence, so it can be located, reproduced, and verified independently.

A methodology built to be examined

A defensible opinion is one that another expert could follow, reproduce, and reach the same conclusion. That is the standard Zenyth's methodology is built to. Every audit follows a defined, repeatable process, and every step of it is documented, so when opposing counsel or a court examines how a conclusion was reached, the answer is already on the record.

The result is an opinion that does not depend on trust. The methodology and the evidence are documented, so the work can be checked rather than taken on faith.

Know what the accessibility evidence is actually worth

In an accessibility matter, the audit on the table is not always sound, whether it is a report your client commissioned before you were involved or the one supporting the plaintiff's claims. Zenyth reviews both and gives you a documented technical analysis of what each one actually establishes. You decide how that analysis applies to the case.

The deliverable is a documented technical opinion, with a supplemental declaration where a matter calls for one, grounded in the same methodology Zenyth applies to its own audits.

A client's earlier accessibility work is often more valuable to the defense than it looks. Courts have increasingly weighed good-faith, demonstrable accessibility efforts in ADA website matters, and a well-documented program can support the arguments your defense may raise, including mootness. Zenyth turns that history into a record that holds up:

  1. Assess the prior work. We review the client's earlier audits and remediation to determine what they actually establish.
  2. Document it defensibly. We capture the scope, scale, methodology, and findings of the work already done, in a form that withstands scrutiny.
  3. Scope the gaps. We identify what a prior vendor left undone or a court would question.
  4. Close them. We remediate and document what is missing, so the program you put forward is both real and complete.

Working with Zenyth

Retaining a technical expert should be straightforward. Here is how Zenyth works with defense counsel across an engagement.

  • Declarations, reports, and testimony

    Zenyth produces written declarations and technical reports documented to evidentiary standards, whether to rebut a plaintiff's expert or to establish your own affirmative record. If a matter reaches deposition or trial, the same expert who built the record is available to testify to it.

  • Transparent, separate fee structure

    Expert witness and technical opinion work is scoped and priced separately from any client remediation engagement, with no bundling and no ambiguity about what you are retaining Zenyth for.

  • Coordination on your terms

    Zenyth works within your litigation timeline and your preferred channels, briefing you and your client as needed, responding when a filing or a plaintiff's report sets a deadline, and staying available as a matter develops. You direct the strategy; Zenyth supplies the technical work behind it.

Yes. Zenyth provides expert witness services for ADA accessibility matters, including written declarations, technical reports, and testimony at deposition or trial when a matter requires it. The expert who built the record is the one who stands behind it.

Zenyth's methodology is built to withstand Daubert scrutiny. Every opinion rests on a cited WCAG success criterion, a documented and repeatable test method, and reproducible evidence, so the reasoning behind a conclusion can be followed and verified by another expert rather than taken on faith.

No. Zenyth is a technical accessibility expert, not a law firm. We provide documented technical analysis and opinions, and you decide how to apply them to the matter. You direct the strategy; Zenyth supplies the technical work behind it.

Yes. Zenyth examines a plaintiff's demand letter or expert report and identifies where it fails on the technical facts, findings that do not meet the cited success criterion, general defects that affect all users regardless of disability, and issues wrongly attributed to the site rather than to user error or the assistive technology. We are equally direct about the claims that do hold, so you know where the real risk is.

Expert witness and technical opinion work is scoped and priced separately from any client remediation engagement, with no bundling. Fees depend on the matter, so pricing is discussed directly rather than published.

Zenyth scopes active matters quickly and can deliver a litigation-grade audit in as little as seven days, with declarations and technical opinions produced on your filing and discovery timeline.

Either. A prior vendor's report may assert conformance that was never tested, or document issues in a way that reads against your client. Zenyth assesses what a prior audit actually establishes, documents the client's good-faith accessibility efforts in a defensible form, and closes the gaps a court would question.

No. Expert witness engagements and client referrals are handled separately. Whether you retain Zenyth as your technical expert or refer a client for audit and remediation, each relationship is scoped on its own terms.
