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

CLAGE GmbH is a German-based manufacturer specializing in decentralized hot water supply solutions, including instantaneous water heaters and hot water storage tanks. The company positions itself as a market leader in small instantaneous water heaters, targeting both consumers and professional sectors seeking energy-efficient hot water systems. Their website is professionally designed, content-rich, and offers comprehensive product information, corporate responsibility details, and customer support services. The company maintains an active presence on multiple social media platforms, enhancing brand visibility and customer engagement. Technically, the website employs legacy JavaScript libraries such as jQuery 1.11.0 and integrates LayerSlider and Etracker analytics, indicating a moderately modern infrastructure with room for updates. The site is mobile-optimized and SEO-friendly, providing a good user experience overall. Security-wise, the site uses HTTPS and avoids exposing sensitive data but lacks explicit security headers and uses outdated libraries, which could pose risks. The absence of WHOIS registration data for the domain www.clage.com raises concerns about domain legitimacy, although the website content and company information appear authentic. Privacy and cookie policies are present and GDPR compliant, but no formal security policy or incident response contacts are found. Overall, the website scores well on content quality and privacy compliance but is penalized for domain registration inconsistencies and outdated technical components.

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

4 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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

CLAGE GmbH operates in the energy sector, focusing on hot water supply technologies. Their business model revolves around manufacturing and distributing instantaneous water heaters and related products, supported by after-sales services and product advice. The company targets both residential and commercial customers, emphasizing energy efficiency and decentralized solutions. Market positioning as a leader in small instantaneous water heaters suggests strong competitive advantages. The website's multilingual support and international partner links indicate a broad geographic reach. The partnership ecosystem includes dedicated portals for partners, enhancing collaboration. Growth indicators include active content updates, trade fair participation, and training courses. The company maintains a professional digital presence but should address domain registration transparency to strengthen credibility.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible exposure of sensitive data. However, the use of an outdated jQuery version introduces potential vulnerabilities. The absence of security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No explicit incident response or security policy pages are available, limiting transparency and readiness communication. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. The lack of a vulnerability disclosure program or security.txt file suggests limited engagement with external security researchers. Overall, the security posture is adequate but requires improvements in modern security practices and transparency to mitigate risks effectively.

Recommendations

  1. Update JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  4. Clarify domain registration details and ensure WHOIS data is accurate and publicly available to strengthen trust.
  5. Maintain and enhance GDPR compliance by regularly reviewing privacy and cookie policies and consent mechanisms.

Technical notes

Notes

The website uses a combination of legacy and modern web technologies, including jQuery 1.11.0, jQuery UI, LayerSlider for interactive content, and Etracker for analytics. The site is responsive and optimized for mobile devices, with good SEO practices such as meta tags and structured data (JSON-LD). However, the use of outdated libraries indicates technical debt and potential security risks. Hosting provider and CMS are not explicitly identified, suggesting a custom or proprietary platform. Performance is moderate, with room for optimization in loading speed and accessibility features. The site architecture supports multilingual content and includes extensive navigation menus and product categorizations, enhancing user experience. Technical risks include outdated dependencies and missing security headers, which should be addressed to improve resilience and maintainability.
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.
