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

Kenda Elektrotechnik is a small, locally focused electrical service provider operating in the Köln-Bonn region of Germany. With approximately 40 years of experience, the company offers a range of services including smart home automation, photovoltaic installations, electric vehicle charging solutions, lighting, and general electrical installations. The website is built on WordPress using the Avada theme and integrates modern technologies such as LayerSlider and Leaflet for maps. The site is well-structured, mobile-optimized, and presents a professional image with partner logos from recognized brands. Security posture is adequate with HTTPS enabled, but lacks advanced security headers and published security policies.

Overall, the website reflects a credible and trustworthy small business with room for improvement in security and privacy transparency.

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

      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

The company positions itself as a reliable and experienced electrical contractor serving residential and commercial clients in the Köln-Bonn area. Its business model focuses on providing specialized electrical services with an emphasis on quality, precision, and customer satisfaction. The presence of partner logos suggests established supplier relationships, enhancing credibility. The website content targets local customers seeking modern electrical solutions such as smart home systems and e-mobility infrastructure. The lack of extensive digital marketing or analytics tools indicates a focus on direct customer engagement rather than broad online lead generation.

Security posture

The website employs HTTPS, ensuring encrypted communication. However, it lacks important security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate certain attack vectors. No security or incident response policies are published, and no dedicated security contact channels are provided. The absence of a cookie consent mechanism may expose the company to GDPR compliance risks. No vulnerable libraries or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but could be significantly improved with standard best practices and transparency.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  2. Add a cookie consent banner and detailed cookie policy to comply with GDPR requirements.
  3. Publish a clear security policy and incident response contact information on the website.
  4. Regularly audit and update WordPress plugins and themes to mitigate vulnerabilities.
  5. Consider adding terms of service and data protection officer contact details to enhance trust and compliance.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Avada theme, which provides responsive design and flexible layout options. It uses jQuery and LayerSlider for interactive elements and Leaflet with OpenStreetMap for map integration. Hosting is provided by rzone.de, a German hosting provider, consistent with the local business focus. Performance is moderate with no major issues detected, and mobile optimization is good. SEO is supported by proper meta tags and structured data (JSON-LD for news articles). Accessibility features are basic but present. The technical stack is standard for small business websites, with opportunities to enhance security and privacy features.
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.
