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 operates in the technology sector, specializing in accessibility software and services. Their business model is B2B, focusing on providing tools and consulting to enterprises and organizations needing to comply with accessibility standards such as WCAG, ADA, and Section 508. The company benefits from a strong brand reputation, supported by high-profile customer logos and industry recognition. Revenue streams likely include software licensing, consulting fees, training subscriptions, and remediation services. The partnership ecosystem includes training and documentation platforms directly linked from their main site. Growth indicators include recent product launches and continuous updates to their accessibility tools. The company maintains a professional digital presence with clear navigation and comprehensive resource offerings.

Security posture

Deque Systems demonstrates a mature security posture with HTTPS enforced across the site and use of cookie consent mechanisms to comply with privacy regulations. The presence of multiple third-party analytics and marketing scripts is managed with user consent, reducing privacy risks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, explicit security headers such as X-Frame-Options and X-Content-Type-Options were not clearly identified and should be confirmed. The absence of a public security policy or incident response contact information is a gap that could be addressed to improve transparency and readiness. Overall, the site shows good security hygiene appropriate for an enterprise technology provider.

Recommendations

  1. Implement and verify comprehensive HTTP security headers including X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy.
  2. Publish a dedicated security policy and provide clear incident response contact channels on the website.
  3. Regularly audit and update all third-party scripts and plugins to mitigate vulnerabilities.
  4. Enhance WHOIS transparency by ensuring domain registration details are complete and publicly accessible.
  5. Maintain and improve privacy compliance by updating cookie consent mechanisms and data retention disclosures.

Technical notes

Notes

The website is built on WordPress CMS with a modern front-end stack including jQuery and PrismJS for syntax highlighting. It integrates multiple third-party services such as HubSpot for forms and analytics, Google Analytics and Tag Manager for tracking, Visual Website Optimizer for A/B testing, and Intercom for customer engagement. The site is mobile optimized and uses responsive design techniques. Performance is moderate, with some reliance on external CDNs and scripts. The technical infrastructure supports a professional and scalable digital presence but requires ongoing maintenance to ensure security and performance standards are met.
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.
