The company offers a comprehensive suite of accessibility tools including axe DevTools, axe Auditor, and axe Monitor, alongside consulting, audits, remediation, and training through Deque University. Positioned as a trusted partner to thousands of global brands, Deque maintains a strong market presence with recognized industry leadership and a focus on ethical, cost-effective accessibility solutions. Technically, the website is built on WordPress with modern SEO and analytics integrations including Google Analytics, Amplitude, and Visual Website Optimizer. The site is mobile-optimized, accessible, and employs cookie consent mechanisms compliant with GDPR. The technology stack and infrastructure reflect a mature digital presence with good performance and security practices. Security posture is solid with HTTPS enforced and use of secure third-party services, though explicit security headers and a public vulnerability disclosure policy are not evident.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

2 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Deque Systems holds a strong market position as a leader in accessibility tools and services, with a business model focused on B2B software, consulting, and training. Their revenue streams likely include software subscriptions, professional services, and educational offerings. The company targets enterprises and organizations needing to comply with accessibility laws globally. Their partnership ecosystem includes training platforms and documentation sites, reinforcing their comprehensive service approach. Growth indicators include extensive deployments, high-profile clients, and industry recognition such as the Forbes Accessibility 100. The company’s operations emphasize sustainability and shift-left accessibility strategies, positioning them competitively in the accessibility technology market.

Security posture

Deque Systems exhibits a mature security posture with enforced HTTPS, use of reputable analytics and marketing tools, and cookie consent mechanisms aligned with privacy regulations. However, explicit security policies, incident response contacts, and vulnerability disclosure programs are not publicly visible, representing areas for improvement. No immediate vulnerabilities or security misconfigurations were detected in the website content. The security culture appears proactive but could benefit from enhanced transparency and formalized security documentation to meet evolving compliance standards such as GDPR and NIS2.

Recommendations

  1. Implement and publicly document comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Establish and publish a formal vulnerability disclosure policy and security incident response procedures.
  3. Regularly audit and monitor third-party scripts and integrations for security risks.
  4. Enhance visibility of security and privacy policies to build greater user trust.
  5. Develop a long-term security strategy incorporating continuous compliance and risk management frameworks.

Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
