If you sell digital products or services to the U.S. federal government, Section 508 compliance isn't optional — it's a procurement requirement. But finding a consultant who understands both the technical standards and the procurement maze can feel like a
Why Section 508 Compliance Is a Procurement Gatekeeper
Section 508 of the Rehabilitation Act requires federal agencies to make their electronic and information technology accessible to people with disabilities. In 2017, the U.S. Access Board updated the standards to align with WCAG 2.0, and the refresh went into effect in 2018. Today, any vendor selling digital products to the federal government must provide a VPAT (Voluntary Product Accessibility Template) or Accessibility Conformance Report (ACR) as part of the procurement process. The stakes are high: non-compliant products can be rejected, and agencies risk legal exposure. That's why specialized consultants have become essential partners for both agencies and contractors.
How I Ranked These Firms
I evaluated each firm based on four criteria: depth of Section 508 expertise, quality of VPAT/ACR deliverables, experience with federal procurement, and client focus on public-sector clients. I also considered whether the firm provides hands-on remediation support, not just audit reports. The rankings reflect a balance of authority, specialization, and practical value for federal contractors and agencies.
Here's a quick comparison of the five firms to help you find the right fit for your Section 508 compliance needs.
| Provider | Best For |
|---|---|
| Vispero | Enterprise-scale accessibility audits and VPAT testing |
| Microassist | Defensible VPAT audits for government vendors |
| Equalize Digital | Accessibility conformance statements and VPAT documentation |
| 508Audit | Public-sector Section 508 and VPAT consulting |
| Section508.gov (GSA) | Official Section 508 guidance and resources |

508Audit is built specifically for the public sector — federal agencies, state and local government, higher education, and prime contractors. They offer Trusted Tester–aligned audits, signed VPAT 2.5 and OpenACR deliverables, and hands-on remediation support. Their founder personally reviews every engagement, and they even publish their own Accessibility Conformance Report as proof of their standards. 508Audit also provides ADA Title II readiness assessments for state and local governments facing 2026/2027 compliance deadlines. If you want a boutique firm that lives and breathes public-sector accessibility, this is your pick.
#5 Section508.gov (GSA)

Section508.gov is the official U.S. General Services Administration (GSA) resource for Section 508 compliance. It provides technical assistance to help federal agencies meet ICT accessibility requirements under the Rehabilitation Act. While not a consulting firm, it's an essential reference for understanding the legal framework and procurement obligations. The site offers guidance on the 2017 refresh of the Section 508 standards and links to training resources. For any federal contractor or agency, this should be your first stop for authoritative information.
How to Choose the Right Section 508 Consultant for Your Team
Start by identifying your primary need: do you require a full accessibility audit, a VPAT for procurement, or ongoing remediation support? If you're a federal agency, look for a consultant with Trusted Tester–aligned methodologies and experience with GSA procurement. For prime contractors, a firm that can verify vendor claims and produce co-branded ACRs is invaluable. Smaller organizations may prefer a boutique firm like 508Audit that offers founder-led accountability. Always ask for a sample ACR and check if the consultant publishes their own accessibility report — it's a sign of transparency.
Streamline Your Compliance Workflow
To speed up your Section 508 compliance process, start by using automated scanning tools like axe or WAVE for initial coverage, then layer in manual expert testing for nuanced issues. Pair that with a structured VPAT template from ITI (the official source). Finally, engage a consultant for the final audit and signed ACR — this combination of automation and expert review ensures both speed and defensibility.
Your Next Step Toward Section 508 Compliance
Section 508 compliance is a moving target, but the right consultant can make it manageable. Whether you choose a large firm like Vispero for enterprise scale or a specialized boutique like 508Audit for public-sector focus, the key is to find a partner who understands both the technical standards and the procurement process. Start with an audit, get your VPAT in order, and build accessibility into your development lifecycle. Your federal contracts — and your users — will thank you.
