Established in 1991, the company serves industrial clients, public sector entities, and major customers such as Deutsche Bahn, with international operations in over 30 countries. Their business model focuses on delivering turnkey electrical infrastructure projects with a strong emphasis on quality, reliability, and customer-specific solutions. Technically, the website is built on the Contao CMS platform and employs modern web technologies including HTML5, CSS, JavaScript, and several jQuery-based libraries for enhanced user experience. The site is mobile-optimized with good accessibility and SEO practices. Hosting is provided via rzone.de, with secure HTTPS connections and no detected blocking or WAF interference. From a security standpoint, the website enforces HTTPS, includes privacy consent on its contact form, and avoids exposing sensitive data. However, it lacks explicit security headers and incident response contact information. Google Analytics is present but disabled, reflecting a privacy-conscious approach. The privacy policy is comprehensive and GDPR compliant, though no cookie consent banner is implemented. Overall, Elektro Schulz GmbH presents a professional and trustworthy online presence with strong business credibility and adequate technical and security measures. Recommendations include enhancing security headers, adding incident response details, and implementing cookie consent mechanisms to further improve compliance and security posture.

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

8 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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"

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

Elektro Schulz GmbH holds a solid market position as a specialized electrical engineering service provider with a focus on energy infrastructure projects. Their competitive advantage lies in their extensive experience, certifications such as DIN EN ISO 9001 and Deutsche Bahn prequalification, and a customer-centric, manufacturer-independent approach. The company targets industrial and public sector clients requiring complex electrical installations and energy management. Revenue streams likely derive from project contracts, maintenance services, and energy management solutions. The company demonstrates growth through international projects and a diversified service portfolio. The absence of social media presence suggests a focus on direct B2B relationships and established partnerships. Strategic observations include leveraging certifications and expanding digital presence to enhance market reach.

Security posture

The website exhibits a mature security posture with enforced HTTPS, secure form handling including CSRF tokens, and privacy consent mechanisms on data collection forms. The absence of security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. No vulnerabilities or exposed sensitive data were detected. The commented-out Google Analytics script indicates a cautious approach to user privacy. Lack of explicit incident response contacts and security policies limits transparency in security governance. Overall, the site aligns well with GDPR requirements but could benefit from enhanced security headers and incident response disclosures to strengthen trust and compliance.

Recommendations

  1. Implement HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web vulnerabilities.
  2. Add explicit incident response contact information or a security@ email address to improve transparency and readiness.
  3. Introduce a cookie consent banner or mechanism to comply fully with GDPR cookie regulations.
  4. Review and enable privacy-compliant analytics or remove Google Analytics scripts entirely to maintain user privacy.
  5. Regularly audit and update third-party libraries to avoid potential vulnerabilities and maintain security hygiene.

Technical notes

Notes

The website is built on the Contao CMS platform, utilizing a modern front-end stack with HTML5, CSS, and JavaScript libraries such as jQuery, MediaElement.js, Colorbox, and Swipe.js for enhanced UI components. The site is mobile responsive and optimized for accessibility and SEO with appropriate meta tags and viewport settings. Hosting is managed via rzone.de with secure HTTPS connections. Performance is moderate with no major issues detected. The site uses AJAX for form submission enhancing user experience. There is no evidence of technical debt or deprecated technologies. Opportunities exist to improve security headers and implement advanced privacy controls to align with best practices.
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.
