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. 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, Google APIs

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 manufacturing sector focused on HVAC and air handling solutions. Its business model includes product manufacturing complemented by engineering and customer support services. The long domain age and consistent WHOIS data reinforce its legitimacy. The company leverages digital marketing and analytics tools to engage its target audience of professionals and businesses. The presence of certifications like Environmental Product Declarations (EPD) indicates commitment to sustainability and quality. Social media channels on Facebook, Instagram, and LinkedIn support brand visibility and customer engagement. The website content and structure suggest a medium-sized enterprise with a focus on quality and customer service.

Security posture

The website demonstrates a good security posture with HTTPS enforced and CSRF tokens implemented in login and password reset forms. No exposed sensitive data or vulnerable libraries were detected. However, the absence of security headers such as Content-Security-Policy and lack of published security or incident response policies represent areas for improvement. No vulnerability disclosure or security.txt files were found, which could enhance transparency and trust. Overall, the security maturity is solid but could benefit from formalized policies and additional technical controls.

Recommendations

  1. Implement and publish security headers like Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Create and publicly share a security policy and incident response contact information to improve transparency and readiness.
  3. Add a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance accessibility features to meet compliance standards and improve user experience for all visitors.
  5. Regularly review and audit third-party scripts and tracking tools to mitigate potential security risks.

Technical notes

Notes

The website uses a modern tech stack including Google Tag Manager, Google Analytics, Facebook Pixel, and LinkedIn Insight Tag for analytics and marketing. The HTML and CSS are valid and the site is mobile optimized with good navigation clarity. Performance is moderate, with room for optimization. No CMS or hosting provider was explicitly detected. The site uses CSRF tokens in forms, indicating attention to secure data handling. However, the lack of security headers and formal security policies suggests some technical debt and opportunities for modernization. Overall, the technical infrastructure supports the business well but could be enhanced for security and performance.
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.
