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

7 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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

      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

      • 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';…

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

The company operates in the energy sector, focusing on technical building equipment solutions. Its business model is B2B, targeting developers and building operators needing HVAC and energy optimization services. The website reflects a consistent brand with professional content and legal compliance documents. Partnerships with marketing and container solution providers are evident. The firm likely generates revenue through project design, equipment supply, and maintenance contracts. Market positioning is stable with over 20 years of domain age and consistent WHOIS data. Growth potential exists through expanded service offerings and digital marketing.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, multiple security headers, and use of Google reCAPTCHA to protect forms. Cookie consent mechanisms are in place, supporting GDPR compliance. However, the absence of a public security policy, vulnerability disclosure, or incident response contacts limits transparency. No vulnerabilities or exposed sensitive data were detected in the analysis. Recommendations include publishing security policies and incident response information to enhance trust and readiness.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact channels such as security@ or abuse@ emails.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly review and update third-party scripts and plugins to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses a modern WordPress CMS with the Divi theme and Revolution Slider plugin, ensuring responsive design across devices. It integrates Google Tag Manager and Microsoft Clarity for analytics and user behavior tracking, alongside CookieYes for cookie consent management. Performance is moderate with room for optimization. The site employs standard SEO best practices including meta tags and structured data (JSON-LD). Hosting provider details are not explicit. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring.
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.
