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

The website Energie-Effizienz-Experten (EEE) serves as a specialized directory and informational platform for experts in energy-efficient construction and renovation in Germany. It targets homeowners, businesses, and professionals seeking qualified energy consultants and related services. The platform offers expert listings, search capabilities, and information on funding and efficiency standards, positioning itself as a niche resource in the energy sector. Technically, the site is built on the TYPO3 CMS, a robust and widely used open-source content management system. It integrates modern web technologies including Google Tag Manager and Cookiebot for analytics and cookie consent management, indicating a mature digital infrastructure. The hosting is managed by a professional provider (sec-provider.de), and the site demonstrates good mobile optimization and SEO practices. From a security perspective, the site uses HTTPS and implements a comprehensive cookie consent mechanism compliant with GDPR. However, explicit security headers and incident response policies are not evident, suggesting room for improvement in security hardening and transparency. No vulnerabilities or exposed sensitive data were detected in the provided content. Overall, the website presents a professional and trustworthy front for its business domain, with good privacy compliance and moderate security posture. Strategic enhancements in security policies, contact transparency, and technical security headers would further strengthen its risk profile and user trust.

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

2 findings rated critical or high. Fix these first.

  1. 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"

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Energie-Effizienz-Experten operates in the energy sector, focusing on energy efficiency consulting and expert services for building and renovation projects. Its business model revolves around providing a centralized directory and resource hub for energy experts, facilitating connections with clients. The platform likely generates value through expert listings and possibly partnerships with funding programs. The target market includes both residential and commercial building stakeholders in Germany. The company leverages partnerships with technology providers like TYPO3 and Cookiebot, indicating a collaborative ecosystem. Growth potential exists in expanding expert listings and integrating additional services related to energy efficiency. Competitive advantages include a focused niche, compliance with GDPR, and integration of modern web analytics and consent tools. The absence of direct contact information suggests a possible lead generation or intermediary role rather than direct service provision.

Security posture

The website demonstrates a baseline security maturity with HTTPS enabled and a GDPR-compliant cookie consent mechanism powered by Cookiebot. The use of Google Analytics and Tag Manager is managed with user consent, reflecting good privacy practices. However, the lack of visible security headers such as Content-Security-Policy, X-Frame-Options, and others indicates potential gaps in defense-in-depth strategies. No explicit security or incident response policies are published, and no contact channels for security incidents are provided, which could hinder timely response to threats. No vulnerabilities or sensitive data exposures were detected in the analyzed content. The site would benefit from implementing additional security headers, publishing a security policy, and providing incident response contacts to enhance its security posture and compliance with best practices.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Provide clear contact channels for security incidents, such as security@ or abuse@ email addresses.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are in use.
  5. Enhance accessibility features and conduct periodic security and privacy compliance reviews.

Technical notes

Notes

The website is powered by TYPO3 CMS, a mature and extensible content management system, indicating a solid technical foundation. Integration of Google Tag Manager and Cookiebot shows adoption of modern analytics and privacy management tools. Hosting is managed by sec-provider.de, a professional hosting provider, which suggests reliable infrastructure. Performance is moderate with preloading of key images and compressed CSS/JS assets. The site is mobile optimized and includes viewport meta tags. Accessibility is basic but could be improved with more ARIA roles and semantic HTML enhancements. SEO is supported by meta descriptions, keywords, and canonical URLs. No critical technical debt or deprecated technologies were detected. Opportunities exist to improve security headers and enhance accessibility compliance to further modernize the platform.
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.
