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

ELEKTRO-LUMEN, s. r. o. is a Czech manufacturer specializing in interior and exterior LED lighting solutions with over 25 years of experience. The company emphasizes smart city integration through its Lumen Smart concept, offering intelligent control and management of public lighting infrastructure. The website reflects a well-established business with international design awards and multiple ISO certifications, targeting municipalities and commercial clients seeking energy-efficient lighting solutions. Technically, the website employs modern tracking and analytics tools such as Google Tag Manager and Google Analytics, with a cookie consent mechanism ensuring GDPR compliance. Security posture is solid with HTTPS enforced and form protection, though lacking some advanced security headers and explicit incident response information. The absence of WHOIS data reduces transparency and trust slightly, but overall the site is professional, accessible, and business credible.

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 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

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 holds a strong market position in the Czech Republic's energy and lighting sector, leveraging product design excellence and smart city technology integration. Its business model combines manufacturing with consulting, engineering, installation, and maintenance services. The presence of international awards and ISO certifications enhances its competitive advantage. The website's partner domain lumenlights.eu indicates a broader ecosystem for smart city solutions. The target audience includes municipalities, industries, healthcare, education, and commercial centers. Growth potential is supported by smart infrastructure trends and energy efficiency demands.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS and cookie consent in place. However, it lacks explicit security headers such as Content-Security-Policy and does not provide a public security policy or vulnerability disclosure program. No incident response contacts or security@ emails are listed, which could hinder timely reporting of security issues. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is adequate for the business type but could be improved to align with best practices and compliance standards.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Verify and update WHOIS registration data to improve transparency and trustworthiness.
  5. Enhance accessibility features and conduct regular security audits to maintain compliance and security posture.

Technical notes

Notes

The website uses a modern tech stack with Google Tag Manager and Google Analytics for tracking, and WebFont Loader for font management. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate with no major issues detected. The absence of a detected CMS suggests a custom or static site architecture. The site uses JavaScript for form protection and cookie consent management. SEO is supported by proper meta tags and structured navigation. Hosting provider details are not evident from the content. Technical risks include missing security headers and incomplete WHOIS data which could impact trust and security.
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.
