0–100, higher is better. How it is calculated

Air Quality Services Ltd is a UK-based ductwork contracting company established in 2004, specializing in the supply, installation, and commissioning of high-quality ductwork ventilation systems. Operating primarily in the High Wycombe and Leeds regions, the company serves clients in the construction, hospitality, leisure, and educational sectors. The business holds multiple industry accreditations including B&ES, BPEC, SafeContractor, and Constructionline, reinforcing its market credibility. Technically, the website is built on WordPress with a standard set of plugins and libraries such as Yoast SEO, Bootstrap, and jQuery. The site demonstrates good content quality, clear navigation, and basic mobile optimization. However, some technical improvements are recommended, including updating legacy libraries and enhancing security headers. From a security perspective, the website uses HTTPS and standard WordPress security practices but lacks explicit security headers and privacy/cookie policies, which are important for GDPR compliance and user trust. The WHOIS data for the domain is unavailable due to a domain naming rules error, which introduces some uncertainty about domain legitimacy, although the website content and business information appear professional and consistent. Overall, the website presents a credible business with room for improvement in privacy compliance and security posture. Strategic enhancements in these areas will strengthen trust and regulatory adherence.

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

9 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

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

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

Air Quality Services Ltd occupies a niche market in the UK ductwork contracting industry with a focus on mechanical and electrical services. Their competitive advantage lies in their long-standing industry experience, regional office presence, and multiple accreditations. The company targets B2B clients such as developers and contractors in residential, hospitality, and educational sectors. The business model is service-oriented with a focus on quality and timely project delivery. The website reflects a stable, small-sized enterprise with consistent branding and professional communication channels. There is no evidence of parent or subsidiary companies. The partnership ecosystem includes industry bodies but no direct business partners are identified from the website content.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and no visible sensitive data exposure. However, the absence of key security headers (e.g., Content Security Policy, HSTS) and lack of explicit privacy and cookie policies indicate gaps in compliance and security best practices. The use of an outdated jQuery version may pose vulnerabilities. No incident response or security contact information is provided, limiting readiness for security events. Overall, the security posture is functional but requires enhancements to meet modern standards and regulatory requirements such as GDPR.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Add and configure security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Update all JavaScript libraries and WordPress plugins to their latest secure versions to mitigate vulnerabilities.
  4. Publish clear incident response and security contact information to enhance transparency and readiness.
  5. Conduct regular security audits and penetration testing to identify and remediate potential vulnerabilities.

Technical notes

Notes

The website is built on WordPress 5.3.21 with a Bootstrap-based theme and uses common plugins such as Yoast SEO and Contact Form 7. The technology stack is somewhat dated, particularly the jQuery version (1.12.4), which may introduce security risks. The site loads multiple external resources including Google Fonts and social media icons. Performance is moderate with basic mobile optimization and accessibility features. SEO is well addressed through meta tags and structured data (JSON-LD). There is no evidence of advanced hosting or CDN services. Technical debt is moderate, and modernization efforts would improve security and user experience.
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.
