Security score

44/100

Risk levelHigh

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

EFEN GmbH operates a professional website focused on providing optimized safety systems for electrical energy distribution. The company targets industrial and infrastructure sectors requiring reliable and safe energy supply solutions. The website reflects a medium-sized business with a long-standing market presence since 2007, supported by a consistent brand and clear service offerings. Technically, the site uses legacy JavaScript libraries such as jQuery and jQuery UI, hosted on Forpsi nameservers, with moderate performance and basic mobile optimization. Security posture is moderate, with cookie consent mechanisms implemented but lacking explicit security headers and visible HTTPS enforcement in the provided data. Privacy compliance is good, with GDPR-aligned cookie and privacy policies. Contact information is primarily via a contact page, with no direct emails or phone numbers on the main page. Overall, the site is trustworthy and professional but could improve security and technical modernization.

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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      Third-party services without privacy policy

      Detected services: YouTube, Cloudflare, Google APIs

      What to do: Document all third-party data sharing in your privacy policy

  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 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"

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.

Add-on

Leaked records that mention efen.sk, from OffSeq Breach.

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 is positioned as a specialist in energy distribution safety with over 90 years of experience. Their business model focuses on B2B manufacturing and distribution of electrical safety components, supported by technical hotline services and comprehensive product catalogs. The company serves industrial clients and infrastructure projects, emphasizing reliability and safety. The website supports this positioning with multilingual content and structured navigation. The absence of direct contact details on the main page suggests a controlled communication channel via the catalog subdomain. The company maintains a YouTube channel for outreach but has limited social media presence otherwise. No advertising or affiliate marketing is evident, indicating a focus on direct business relationships.

Security posture

The website demonstrates a moderate security posture. It employs cookie consent tools compliant with GDPR, indicating awareness of privacy regulations. However, the absence of visible security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces the overall security robustness. No incident response or security policy pages are found, and no vulnerability disclosure or security.txt files are present. The use of older JavaScript libraries may pose potential risks if not regularly updated. No exposed sensitive data or obvious vulnerabilities are detected in the HTML content. The site lacks visible HTTPS enforcement data, which is critical for secure communications. Overall, the security maturity is adequate but requires enhancements to meet best practices.

Recommendations

  1. Implement and enforce HTTPS with strong SSL/TLS configurations and HSTS headers.
  2. Add comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  4. Update legacy JavaScript libraries to current versions to mitigate known vulnerabilities.
  5. Enhance contact information visibility to improve user trust and communication.

Technical notes

Notes

The website uses a traditional tech stack centered around jQuery and jQuery UI, with bxSlider for image sliders and cookie consent plugins for privacy compliance. The hosting is inferred to be with Forpsi based on nameservers. The site lacks a modern CMS and appears to be custom-built or static. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with meta tags present but no advanced structured data like JSON-LD or Open Graph tags detected. The site could benefit from modernization to improve performance, accessibility, and security. No analytics or advanced marketing tools are detected, indicating a low footprint in user tracking and data collection.
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.
