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

Aermec UK Ltd. is a well-established company specializing in Heating, Ventilation, and Air Conditioning (HVAC) solutions for industrial and commercial sectors. With over 60 years of market presence in Europe, they position themselves as market leaders in systems engineering, offering a broad range of HVAC products, servicing, repairs, and comprehensive system testing. Their website reflects a professional and detailed presentation of their products and services, targeting industry and commercial enterprises requiring HVAC solutions. Technically, the website is built on WordPress using Elementor and Yoast SEO, indicating a modern and maintainable infrastructure. The site is mobile-optimized and includes SEO best practices such as structured data and meta tags. Performance is moderate, with standard use of JavaScript libraries and tracking tools like Google Analytics and Tag Manager. From a security perspective, the site uses HTTPS with good SSL configuration but lacks visible security headers and explicit privacy or cookie policies, which are important for GDPR compliance. No incident response or vulnerability disclosure information is present, which could be improved to enhance trust and security posture. Overall, the website is professional and credible, but the domain WHOIS data is unavailable and flagged as invalid by the registry, which raises concerns about domain legitimacy or configuration. This discrepancy should be addressed to ensure full trustworthiness and compliance.

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

Aermec UK Ltd. operates in the HVAC manufacturing and service sector, serving industrial and commercial clients. Their competitive advantage lies in their long-standing market presence, technical expertise, and comprehensive service offerings including commissioning, maintenance, and energy efficiency retrofits. The company invests in R&D and testing facilities, positioning itself as a technical leader. Their business model combines product sales with value-added services, targeting sectors such as offices, data centers, healthcare, leisure, retail, and education. The website indicates active engagement with customers through newsletters and news updates, supporting growth and customer retention. Partnerships or subsidiaries are not explicitly identified on the site.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, ensuring encrypted communications. However, the absence of security headers like Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces protection against common web attacks. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Forms are secured with required fields but lack visible anti-CSRF tokens or CAPTCHA mechanisms. The lack of a published security policy or incident response plan limits transparency and preparedness. GDPR compliance is partial due to missing privacy and cookie policies. Enhancing these areas would improve the security posture and regulatory compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the website.
  3. Publish an incident response plan and vulnerability disclosure policy to improve transparency and trust.
  4. Review and correct domain registration issues to ensure WHOIS data accuracy and domain legitimacy.
  5. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on a WordPress CMS platform using the Elementor page builder and Yoast SEO plugin, indicating a modern and flexible technical stack. It uses jQuery and Swiper.js for interactive elements and sliders. The site is mobile responsive and includes structured data (JSON-LD) for SEO enhancement. Performance is moderate with standard use of external scripts including Google Analytics and Tag Manager. No hosting provider information was detected. Accessibility features are basic, with room for improvement in ARIA roles and keyboard navigation support. The site uses external fonts from Adobe Typekit. Overall, the technical implementation supports a professional user experience but could benefit from performance optimization and enhanced accessibility.
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.
