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

EFEN GmbH is a German company specializing in the development and manufacturing of electrical safety components and systems for the energy, infrastructure, and industrial sectors. Established since 1993 and ISO certified, EFEN positions itself as a reliable and quality-focused manufacturer with a strong presence in the German and European markets. The company offers an online shop for easy ordering of components and provides technical support to its customers. The website reflects a professional and consistent brand image with clear navigation and relevant content tailored to its target audience. Technically, the website is built on WordPress with modern libraries such as jQuery and Slick Slider, ensuring a responsive and accessible user experience. SEO and accessibility features are well implemented, and the site includes a comprehensive cookie consent mechanism aligned with GDPR requirements. However, some improvements could be made in security headers and incident response transparency. From a security perspective, the site uses HTTPS and has implemented cookie consent, but lacks explicit security headers and incident response contact information. No vulnerabilities or exposed sensitive data were detected in the content. The absence of WHOIS registration data is a concern, reducing trustworthiness from a domain registration perspective, although the website content and business presence suggest legitimacy. Overall, EFEN GmbH's website is professional, secure, and compliant with privacy regulations, but the missing WHOIS data and lack of some security best practices suggest areas for improvement. Strategic recommendations include enhancing security headers, publishing a security policy, and verifying domain registration details to improve 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. 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"

    • 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';…

  2. 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

  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

      SSL Certificate Expires Soon

      SSL certificate expires in 11 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography

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

EFEN GmbH operates in the energy sector, focusing on manufacturing and selling electrical safety components. The company benefits from ISO certification and active participation in industry associations, which strengthens its market position and credibility. Its business model combines manufacturing with direct online sales, targeting industrial, infrastructure, and energy customers primarily in Germany and neighboring countries. The presence of localized domains for Slovakia and Poland indicates regional expansion. EFEN's digital ecosystem includes social media engagement and a dedicated online shop, supporting customer acquisition and service. The company shows signs of medium size with a well-structured website and consistent branding, positioning it as a trusted player in its niche market.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS encryption and a GDPR-compliant cookie consent mechanism. However, the absence of HTTP security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options reduces the overall security hardening. No incident response or security policy pages were found, which limits transparency and readiness for security incidents. The use of third-party analytics and marketing cookies is disclosed and managed via consent, aligning with privacy regulations. The missing WHOIS data is a notable gap, potentially indicating privacy protection or domain registration issues, which could affect trust. Overall, the security posture is adequate but could be improved with enhanced headers and incident response information.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response contact information to improve transparency and readiness.
  3. Verify and update WHOIS domain registration information to increase trust and legitimacy.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  5. Enhance monitoring and logging to detect and respond to security incidents effectively.

Technical notes

Notes

The website is built on WordPress 6.8.3, leveraging modern JavaScript libraries such as jQuery 3.6.3 and Slick Slider for interactive UI components. FontAwesome 6.3.0 is used for iconography. The site includes multiple CSS stylesheets for layout, accessibility, and theming, indicating attention to design and user experience. SEO is supported by the All in One SEO plugin, with proper meta tags and structured data (JSON-LD) for organization and breadcrumb navigation. Performance is moderate, with asynchronous loading of scripts and responsive design for mobile devices. Accessibility features include keyboard navigation aids and contrast/font size adjustments. Hosting provider details are not explicitly identified. Overall, the technical implementation is solid with room for optimization in security headers and performance tuning.
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.
