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

CLAGE GmbH is a German-based company specializing in decentralized warm water supply solutions, including a wide range of instantaneous water heaters, warm water storage, and Zip water systems. The company holds a market-leading position in small instantaneous water heaters and offers extensive product consultation, support, and training services. Their website is professionally designed, well-structured, and targets end consumers, architects, planners, and partners in the energy and water heating sector. Technically, the website uses a mix of legacy and modern JavaScript libraries, with moderate performance and good mobile optimization. Security posture is generally good with HTTPS enforced and cookie consent mechanisms, but lacks some advanced security headers and uses an outdated jQuery version, which could pose risks. The absence of WHOIS registration data is a concern but does not detract significantly from the website's credibility given the professional presentation and active content. Overall, the website demonstrates a mature digital presence with room for security and compliance improvements.

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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention clage.de, from OffSeq Breach.

No leaked records found

Breach holds no records for clage.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

CLAGE operates in the energy sector focusing on warm water solutions, serving a medium-sized market with a strong emphasis on product quality and energy efficiency. Their business model includes manufacturing, direct sales via an online shop, and extensive partner networks. The company leverages social media and digital marketing to engage customers and professionals. The presence of detailed product catalogs, live seminars, and corporate responsibility initiatives indicates a strategic approach to market leadership and customer trust. Partnerships with specialized portals and tender platforms further enhance their market reach. The company’s digital ecosystem supports growth and customer engagement effectively.

Security posture

The website enforces HTTPS and implements cookie consent, reflecting compliance with GDPR and basic security best practices. However, the use of an outdated jQuery version introduces potential vulnerabilities. The absence of explicit security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No dedicated security or incident response policies are published, which could impact incident handling readiness. The lack of a security.txt file or vulnerability disclosure mechanism limits transparency for security researchers. Overall, the security posture is moderate but could benefit from modernization and formalized policies.

Recommendations

  1. Upgrade jQuery and other JavaScript libraries to current secure versions to mitigate known vulnerabilities.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish explicit security and incident response policies to improve transparency and preparedness.
  4. Add a security.txt file to facilitate responsible vulnerability disclosure.
  5. Regularly audit WHOIS domain registration status to ensure domain legitimacy and continuity.

Technical notes

Notes

The website uses a combination of jQuery 1.11.0, jQuery UI, and LayerSlider for interactive elements, supported by custom scripts and CSS. Analytics are handled via Etracker, with cookie consent implemented. The site is mobile responsive with good SEO metadata and structured data using JSON-LD for organization info. Performance is moderate, with some legacy scripts that could be optimized. Accessibility features are basic but present. Hosting provider details are not disclosed. The technical stack is stable but would benefit from modernization and enhanced security configurations.
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.
