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

COSMO is a German company specializing in heating and ventilation products and services, targeting both end consumers and professional markets. Their website showcases a range of products including solar technology, radiators, underfloor heating, and air ventilation systems, supported by tools like energy saving calculators and floor planners. The company positions itself as a provider of high-quality, innovative heating and ventilation solutions with a focus on comfort and energy efficiency. Technically, the website is built on Drupal 10, leveraging modern front-end libraries such as Swiper.js for interactive elements, and integrates third-party services like Google Maps API and Adobe Launch for analytics and marketing. Usercentrics CMP is implemented for cookie consent, reflecting GDPR compliance efforts. Hosting is provided by Adacor, a reputable German hosting provider. From a security perspective, the site enforces HTTPS and uses cookie consent mechanisms but lacks explicit security headers and published security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the analyzed content. Privacy compliance is partial due to the absence of a visible privacy policy and terms of service. Overall, the website is professional, well-structured, and trustworthy, with good content quality and technical implementation. Strategic improvements include publishing comprehensive privacy and security policies, adding security headers, and providing vulnerability disclosure information to enhance trust 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

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 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 Content-Security-Policy header

      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

COSMO operates in the energy sector, focusing on heating and ventilation solutions. Their business model includes product sales and digital tools to support customer decision-making, targeting both consumers and professionals. The company demonstrates a medium-sized enterprise profile with a consistent brand presence and a clear market position in Germany. The website content and tools suggest a customer-centric approach with an emphasis on energy efficiency and modern heating technologies. Partnerships or subsidiaries were not identified in the provided data. The company leverages digital marketing and analytics tools to support growth and customer engagement.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and GDPR cookie consent implemented via Usercentrics. However, it lacks explicit security headers such as Content Security Policy, HSTS, and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No security or incident response policies are published, and no vulnerability disclosure or security.txt files are present. The absence of direct contact emails or phone numbers for security incidents limits incident response readiness. No exposed sensitive data or vulnerable libraries were detected. Overall, the security posture is adequate but could be significantly improved by adopting best practices and transparency measures.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the website footer or main navigation.
  2. Implement and configure security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common attacks.
  3. Create and publish a security policy and incident response contact information, including a dedicated security email address.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance accessibility features and provide more direct contact information to improve user trust and compliance.

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.
