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

1 finding rated critical or high. Fix these first.

  1. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

CHAS holds a strong market position as a trusted authority in health and safety compliance within the UK construction and contracting sectors. Their competitive advantage lies in their long-standing industry presence, recognized accreditation standards, and comprehensive service offerings. The website indicates a focus on digital engagement through membership portals and resource sharing. CHAS leverages partnerships and social media channels to enhance visibility and customer engagement. The business model is subscription/membership-based, generating revenue through certification services and compliance assessments. The target audience includes contractors, suppliers, and organizations seeking to mitigate health and safety risks in their supply chains.

Security posture

The website demonstrates a mature security posture with HTTPS enforced, appropriate security headers, and no visible exposure of sensitive data. The use of reputable third-party analytics and consent management tools indicates attention to privacy compliance. However, the absence of a public security policy, incident response information, and vulnerability disclosure mechanisms suggests areas for improvement in transparency and security governance. No critical vulnerabilities or outdated libraries were detected in the site content. Overall, the security posture is strong but could benefit from enhanced communication of security practices and incident handling.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and practices.
  2. Implement and publicize an incident response plan and contact channels for security issues.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure.
  4. Regularly review and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency around data retention policies and user privacy protections.

Technical notes

Notes

The website is built on WordPress using WPBakery Page Builder, leveraging modern JavaScript libraries such as jQuery and Vimeo Player. It integrates multiple analytics and marketing tools including Google Tag Manager, Microsoft Clarity, and Cookiebot for consent management. The site is mobile-optimized with good accessibility and SEO practices evident from meta tags and structured data. Performance is moderate, with some use of CDN resources for fonts and external assets. The technical infrastructure is robust and supports a professional user experience, though hosting provider details are not explicitly identified. Opportunities exist to improve performance optimization and enhance security transparency.
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.
