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

EFEN GmbH is a German company specializing in the development and production of electrical safety components for smart energy distribution, serving industries such as infrastructure and energy supply. The company is ISO certified since 1993 and maintains a strong presence in industry associations, reflecting a reputable market position. Their business model includes manufacturing and direct online sales through a dedicated e-commerce platform. The website demonstrates a professional digital presence with modern technologies and multilingual support. Technically, the site is built on WordPress with common libraries like jQuery and uses HTTPS with cookie consent mechanisms, indicating a mature digital infrastructure. Security posture is generally good with HTTPS and consent management, but lacks explicit security headers and incident response disclosures. WHOIS data is unavailable, which raises some concerns about domain registration transparency but does not detract significantly from the overall legitimacy given the professional site and business indicators. Overall, the site is trustworthy, well-structured, and compliant with GDPR, serving a B2B audience effectively.

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 12 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
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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 electrical safety products. Their competitive advantage lies in German manufacturing quality, ISO certification, and active participation in industry bodies. Revenue streams include product sales via an online shop and technical consulting. Target customers are industrial and infrastructure clients requiring reliable energy distribution components. The company shows growth potential through digital sales channels and multilingual support for international markets. Partnerships include the efen-sales.com domain for e-commerce. The company maintains a consistent brand and professional content, supporting strong market credibility.

Security posture

The website enforces HTTPS and implements a comprehensive cookie consent banner with granular user controls, reflecting good privacy practices. However, no security headers such as Content Security Policy or HSTS were detected, which are recommended to enhance protection against common web attacks. No incident response or vulnerability disclosure information is publicly available, which could be improved to demonstrate security maturity. The use of third-party analytics and marketing pixels is transparent and consent-based, aligning with GDPR requirements. Overall, the security posture is solid but could benefit from additional technical controls and transparency.

Recommendations

  1. Implement security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen web security.
  2. Publish an incident response policy and provide dedicated security contact information to improve transparency and readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Add clear company phone contact information to enhance user trust and accessibility.
  5. Consider verifying and publishing WHOIS domain registration details to improve domain legitimacy and trust.

Technical notes

Notes

The website is built on WordPress 6.8.2 using modern JavaScript libraries such as jQuery 3.6.3 and Slick Slider for UI components. FontAwesome 6.3.0 is used for icons. The site is mobile optimized with responsive design and includes SEO best practices like meta tags and structured data (JSON-LD). Performance is moderate, with no major issues detected. Accessibility is basic but could be improved with more ARIA attributes and keyboard navigation enhancements. Hosting provider details are not disclosed. Overall, the technical infrastructure is stable and suitable for a medium-sized B2B company.
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.
