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

Koop is a Czech Republic-based company specializing in energy consultancy and sustainable energy solutions. The company targets businesses and organizations seeking to improve energy efficiency and implement sustainable energy projects. The website presents a professional image with clear contact information and comprehensive privacy and cookie policies, indicating a commitment to compliance and user privacy. Technically, the site is built using modern frameworks such as Next.js and Tailwind CSS, ensuring a responsive and user-friendly experience. Security posture is strong with HTTPS enforcement and appropriate security headers, though the absence of a published security policy and vulnerability disclosure reduces transparency. The lack of WHOIS data is a concern for domain legitimacy but does not detract significantly from the overall trust in the business based on website content. Strategic recommendations include publishing a security policy, adding vulnerability disclosure mechanisms, and enhancing accessibility features to improve compliance and user experience.

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

7 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

      No Cookie Policy found

      GDPR requires clear information about cookie usage

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

    • 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

  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

      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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Koop operates in the energy sector with a focus on consultancy and sustainable solutions. The company appears to be a medium-sized regional player with a clear business model centered on service provision. The website content and structure suggest a well-established market position with professional branding and consistent messaging. The absence of extensive marketing or advertising tools indicates a focus on direct business relationships rather than mass consumer marketing. The company maintains clear contact channels and legal information, supporting credibility. Growth opportunities may lie in expanding digital presence and enhancing transparency around security and compliance.

Security posture

The website demonstrates a good security posture with HTTPS enabled and multiple security headers implemented. There is no evidence of exposed sensitive data or vulnerable libraries. However, the absence of a dedicated security policy page and vulnerability disclosure program limits the transparency of security practices. No incident response contacts or security-specific communication channels were found. The site does not appear to use extensive tracking or analytics, reducing privacy risks. Overall, the security maturity is moderate to good, with room for improvement in policy transparency and incident readiness.

Recommendations

  1. Publish a comprehensive security policy page outlining security practices and commitments.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Enhance website accessibility to meet higher standards and improve user inclusivity.
  4. Consider adding incident response contact information to improve transparency and readiness.
  5. Increase transparency around data retention and privacy practices to strengthen GDPR compliance.

Technical notes

Notes

The website is built on a modern technology stack including React and Next.js, with Tailwind CSS for styling. This ensures good performance and mobile responsiveness. The site uses preloaded fonts and images for optimization. No CMS was detected, suggesting a custom or framework-based solution. Hosting provider details are not evident from the content. The site shows good SEO practices with proper meta tags and structured content. Accessibility is basic but could be improved. No heavy analytics or tracking scripts were found, indicating a privacy-conscious approach. Overall, the technical infrastructure is solid with opportunities for further optimization and accessibility enhancements.
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.
