What is All in One Accessibility?

This section summarises what to verify if you are evaluating All in One Accessibility. The vendor positions products differently, so use the checklist below when you review their pages or speak to sales.

What to check on vendor pages and documentation

• Product scope: confirm whether the offering focuses on automated scanning, remediation (widgets/overlays), manual audits or a mix.
• Standards claimed: look for explicit references to WCAG 2.1/2.2 and the levels (A/AA/AAA) supported and any claims about Section 508, ADA or EAA.
• Evidence: request a VPAT or accessibility conformance report and sample audit output.
• Integrations: check for CI/CD, CMS (WordPress, Drupal, etc.), and bug-tracker connectors.
• Data handling and security: review hosting model, data retention and any SOC/GDPR statements.

Common limits to verify

• Automated scanners cannot detect all WCAG failures — confirm what percentage of WCAG criteria the vendor says their automation covers and how they handle items needing human judgement.
• If remediation includes overlays/widgets, ask for a technical explanation and independent accessibility audits; overlays are not an accessibility compliance guarantee.
• Check whether the product offers developer-friendly output (issue details, failing HTML/CSS snippets, recommended fixes) versus high-level reports for non-technical stakeholders.

What is Tenon?

Use the same verification approach for Tenon. Below are the practical checks to perform on Tenon’s product and sales documentation so you can compare like for like.

What to check on vendor pages and documentation

• Testing scope: confirm if Tenon focuses on automated testing, manual audits, or combines both.
• Standards coverage: look for explicit support statements for WCAG versions/levels and any regulatory standards relevant to your market.
• VPAT/ACR: request the vendor’s conformance report or VPAT and sample reports.
• Integrations & API: check for a public API, CI/CD integration guides and CMS plugins.
• Support and training: verify SLAs, onboarding help and whether remediation services are offered.

Common limits to verify

• Automated results should be paired with manual verification; confirm Tenon’s approach to false positives and triage workflows.
• Ask how the product treats interactive components, single-page applications and ARIA — these areas often require manual review.

Feature comparison: testing scope, WCAG coverage, integrations and reporting

Rather than naming undocumented feature parity, here’s a short buyer-focused matrix of the questions that reveal real differences between the two vendors. Use this when you request demos or trial access.

1. Automated scanning coverage: Ask the vendor which WCAG success criteria are covered by automation and request a document mapping tool checks to specific WCAG SCs.
2. Manual testing and expert audits: Confirm whether the vendor offers manual audits, staffed expert reviews, or consulting and whether those services are included or charged separately.
3. Reporting formats: Request sample reports in both PDF and machine-readable formats (CSV/JSON) and verify that defect reports include remediation guidance and code examples.
4. Integrations: Verify connectors for your CMS, issue tracker (Jira/GitHub), and whether there is an API or CLI for CI/CD automation.
5. Regulatory evidence: Ask for a VPAT or accessibility conformance report and any third-party audit results to support claims about Section 508, ADA or EAA compliance.

Pricing comparison

Pricing models vary widely across accessibility vendors (per-page scan, per-seat, monthly scan quotas, or enterprise licences). If pricing is not listed publicly, request a written breakdown that includes:

• What the base plan covers (scans per month, number of sites/pages, user seats)
• Costs for additional scan credits, manual audits, remediation services or integrations
• Trial or proof-of-concept options and cancellation terms

If pricing transparency is a deciding factor for you, ask each vendor for a like-for-like quote for the same number of pages, users and audit hours.

Ratings and user reviews

This article does not assert current review scores. Before selecting, check independent review sites (G2, Capterra, TrustRadius) and note:

• Review date and reviewer role (developer, accessibility specialist, product owner)
• Common praise (accuracy of scans, helpfulness of remediation guidance, quality of support)
• Common complaints (false positives, pricing surprises, integration gaps)

Record the retrieval date for any rating you use in procurement documentation.

Ease of use and support

To compare ease of use across both vendors, evaluate the same set of artifacts during a trial or demo:

• Onboarding materials and self-service documentation
• Quality of demo data and how quickly the tool surfaces actionable issues
• Support channels (email, chat, phone), business hours and SLA commitments
• Training and developer resources (API docs, SDKs, code samples)

Document any differences in time-to-value during trial periods — that is often decisive for engineering teams under delivery pressure.

Which one is right for you?

Because vendor claims and product capabilities change, choose based on documented evidence. Use the guidance below to match needs to the right offering.

Choose a vendor if you are:

• Small teams or content owners: favour a product with clear, low-cost scanning plans, guided remediation and easy-to-read reports.
• Developer-led organisations: prioritise a tool with a public API/CLI, CI/CD integration and actionable remediation output (code snippets, failing HTML).
• Enterprises or regulated sectors: require VPAT/ACR documentation, third-party audit evidence, SLAs and flexible licensing for multiple teams.
• Agencies and consultancies: look for per-audit pricing, white-labelling or multi-client management features.

Verdict

There is no reliable winner declared in this article because up-to-date vendor documentation, VPATs and recent user reviews must be checked for both All in One Accessibility and Tenon. The best choice depends on the testing scope you need (automation vs manual), the integrations your engineering workflow requires, and the regulatory evidence you must produce. Use the checklist and comparison questions in this guide when you request demos and written evidence from each vendor.

FAQs

Does either tool guarantee WCAG or legal compliance?

No. Automated tools cannot guarantee full WCAG compliance; compliance requires manual testing, policy and governance. Always request a VPAT/ACR and third-party audit evidence.

Do these products include overlays or widgets that automatically fix issues?

Some accessibility offerings include remediation widgets, but overlays are not a substitute for accessibility-first development. If a vendor offers an overlay, request independent audit results and technical details about how the overlay handles focus, keyboard navigation and ARIA.

How do I verify a vendor’s WCAG coverage claims?

Ask for a mapping document that ties the product’s checks to specific WCAG success criteria, sample reports, and a VPAT or accessibility conformance report. Validate mappings with a short manual audit of representative pages.

Where can I find user ratings and recent reviews?

Check independent review sites such as G2, Capterra and TrustRadius. Note the date of each review and the reviewer’s role to understand context.

What should I request in a proof-of-concept?

Request a trial that includes scans of a representative sample of pages, sample reports in exportable formats, integration demos (API/CI) and a written statement on data handling and security.

If documentation is ambiguous, what next?

Escalate requests to the vendor for formal evidence (VPAT, sample reports), ask for references from customers in your sector, or run a short paid pilot with acceptance criteria tied to specific WCAG checks and remediation output.
