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

Deutsche Energie-Agentur GmbH (dena) is a prominent German energy agency focused on promoting efficient, intelligent, and sustainable energy production and usage. It collaborates with public and private sector partners to advance the energy transition and climate protection efforts in Germany. The website reflects a professional and comprehensive digital presence, leveraging TYPO3 CMS and modern web technologies. It provides detailed information about its mission, projects, and services, targeting stakeholders in the energy sector and government entities. The site supports multiple languages, enhancing accessibility for international audiences. Technically, the website employs a mature infrastructure with strong privacy and consent management mechanisms, including Cookiebot for cookie consent and Matomo and Hotjar for analytics, ensuring GDPR compliance. The site is well-optimized for mobile devices and accessibility, with a clear navigation structure and professional design. Hosting is managed via secure providers, and HTTPS is enforced with appropriate security headers. From a security perspective, the site demonstrates good practices such as secure cookie handling, consent management, and absence of exposed sensitive data. However, explicit security policies, incident response contacts, and vulnerability disclosure mechanisms are not publicly available, representing areas for improvement. Overall, the domain registration and hosting details align with the organization's legitimacy, supporting a high trust level. The overall risk assessment is low, with no indications of malicious content or security vulnerabilities. Strategic recommendations include publishing formal security and incident response policies, adding vulnerability disclosure information, and providing direct security contact channels to enhance transparency and 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

4 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 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. 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.

  3. 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

dena operates as a key governmental and non-profit entity in Germany's energy sector, focusing on energy efficiency and climate protection. Its market position is strong, serving as a central hub for energy transition initiatives. The business model revolves around collaboration with public and private partners, offering consulting, project management, and policy support services. The website's content and structure indicate a mature organization with a large operational scale. The partnership ecosystem includes event subdomains and integration with recognized third-party services for analytics and consent management. Growth indicators include multilingual support and comprehensive project portfolios. The absence of direct contact emails suggests a preference for controlled communication channels, likely to manage inquiries efficiently.

Security posture

The website exhibits a solid security posture with enforced HTTPS, modern security headers, and robust cookie consent management. Use of Matomo and Hotjar analytics is governed by user consent, aligning with GDPR requirements. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of published security policies, incident response procedures, and vulnerability disclosure channels limits transparency and may hinder rapid response to security incidents. The security score is high but could be improved by addressing these gaps. The organization should consider formalizing and publishing these policies to demonstrate commitment to security and compliance.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and publish a vulnerability disclosure policy or security.txt file.
  3. Provide direct security contact emails such as security@ or abuse@ dena.de.
  4. Regularly audit third-party scripts and libraries for vulnerabilities and update accordingly.
  5. Enhance transparency by including data protection officer contact details and compliance certifications.

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.
