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

6 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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 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';…

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

COMBITHERM operates in the energy sector, focusing on sustainable and efficient refrigeration and heating technologies. Their competitive advantage lies in customized product solutions, high energy efficiency, and innovative heat pump technology including high-temperature models up to 120°C. The company targets industrial clients across various sectors such as automotive, banking, IT centers, airports, hospitals, and food industry. Their business model emphasizes quality manufacturing, customer satisfaction, and after-sales service. The company maintains partnerships with well-known suppliers and participates in industry trade fairs, enhancing their market visibility. Growth indicators include continuous product development and a strong emphasis on sustainability and decarbonization. The company leverages a worldwide network but remains a medium-sized family business. Strategic observations suggest opportunities in expanding digital marketing and enhancing security transparency to further strengthen market position.

Security posture

The website exhibits a good security maturity level with mandatory HTTPS encryption and secure handling of contact forms. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the absence of visible security headers such as Content-Security-Policy and lack of a published incident response or security policy page indicate areas for improvement. The privacy policy is comprehensive and GDPR compliant, which is a positive compliance indicator. No vulnerability disclosure or security.txt file was found, which could limit transparency and responsiveness to security issues. Overall, the security posture is solid but could benefit from enhanced security communication and technical header implementations to mitigate risks and improve trust.

Recommendations

  1. Implement a cookie consent banner and detailed cookie policy to comply fully with GDPR requirements.
  2. Publish a dedicated security policy and incident response information to enhance transparency and preparedness.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common web attacks.
  4. Regularly audit and update third-party scripts and libraries to avoid vulnerabilities.
  5. Consider creating and publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.

Google Analytics is used for user behavior tracking, though no explicit cookie consent mechanism is present. The site is mobile optimized with responsive design and good navigation clarity.

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.
