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

STRIEBEL & JOHN is a German-based company specializing in energy distribution systems and electrical installation products. Their website showcases a range of innovative solutions such as CombiLine mounting plates, wiring systems, and multifunction enclosures, targeting electrical installers and industry professionals. The company maintains a professional online presence with consistent branding and active social media channels. Technically, the website is built on Drupal 11, employs modern web technologies including lazy loading and consent management via Usercentrics, and uses Google Tag Manager for analytics. The site is mobile-optimized and SEO-friendly, providing a good user experience. Security-wise, the site enforces HTTPS and integrates GDPR-compliant consent mechanisms but lacks explicit security headers and detailed security policies. The absence of WHOIS registration data raises concerns about domain legitimacy, although the website content and structure suggest a legitimate business. Overall, the site scores well in content quality and security posture but is penalized for missing domain registration transparency and contact details.

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 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

      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

  4. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

STRIEBEL & JOHN operates in the energy sector with a focus on manufacturing and supplying electrical distribution systems. Their business model revolves around product innovation and efficiency improvements for electrical installations. The company targets professional installers and industrial clients, leveraging digital tools such as virtual factory tours and online catalogs to enhance customer engagement. Their partnership with ABB and references to regulatory standards indicate a strong market position and compliance orientation. The website's content and structure reflect a medium-sized enterprise with a solid reputation in Germany and international reach. The lack of visible direct contact information on the homepage suggests a possible focus on registered users or B2B clients accessing detailed support via login.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS, GDPR-compliant cookie consent via Usercentrics, and no visible exposure of sensitive data. However, the absence of common security headers like Content-Security-Policy and X-Frame-Options is a gap that could be exploited in certain attack scenarios. No incident response or vulnerability disclosure information is provided, which limits transparency and readiness perception. The missing WHOIS data is a significant red flag for domain legitimacy and trust. Overall, the security posture is good but could be improved by adding explicit security policies, incident response contacts, and publishing a security.txt file.

Recommendations

  1. Implement and verify HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response page including contact channels for vulnerability reporting to improve transparency and trust.
  3. Investigate and resolve the missing WHOIS domain registration data to ensure domain legitimacy and improve business credibility.
  4. Add clear and accessible company contact information including emails and phone numbers on the website to facilitate communication and support.
  5. Regularly audit third-party scripts and tracking tools to ensure compliance with privacy regulations and minimize user tracking.

Technical notes

Notes

The website is built on Drupal 11 CMS, leveraging modern JavaScript libraries such as lazysizes for image lazy loading and Google Tag Manager for analytics. Usercentrics is integrated for GDPR-compliant consent management. The site is mobile-optimized with responsive design and includes SEO best practices like canonical URLs and meta tags. Performance is moderate, with asynchronous loading of scripts and deferred styles. No hosting provider information is directly available. The technical stack is modern and well-maintained, though improvements in security headers and accessibility features could be made. The absence of WHOIS data is a technical anomaly that should be addressed to avoid trust issues.
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.
