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

      Missing X-Frame-Options header

      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, focusing on electricity and gas supply within the Czech market. Their business model revolves around direct energy provision and consulting services, targeting households and businesses. The company benefits from a consistent brand and clear communication channels, including verified contact emails and phone numbers. KOOP's digital presence leverages modern web technologies and integrates standard marketing and analytics tools like Google Analytics and Facebook Pixel. The absence of major vulnerabilities and the presence of GDPR-compliant policies enhance their credibility. KOOP's market positioning as a regional energy provider is supported by their long operational history and transparent business information.

Security posture

The website enforces HTTPS with an excellent SSL configuration and includes multiple security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options, indicating a mature security posture. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy or incident response page and lack of a vulnerability disclosure mechanism represent areas for improvement. The company should consider publishing these to enhance transparency and readiness. Overall, KOOP maintains a strong security baseline appropriate for their industry and business size.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and commitments.
  2. Establish and publicize an incident response contact or procedure to improve transparency and readiness.
  3. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to improve compliance and user experience for all users.
  5. Regularly review and update third-party scripts and tracking tools to minimize privacy risks.

Technical notes

Notes

KOOP's website is built using Next.js and React, leveraging Tailwind CSS for styling, which supports responsive and modern UI design. The site uses Google Tag Manager and Google Analytics for marketing and analytics purposes. Performance is moderate, with good mobile optimization and basic accessibility features. The site does not appear to use a common CMS, suggesting a custom or proprietary solution. Hosting provider details are not explicitly detected. The technical stack is modern and well-maintained, though opportunities exist to improve accessibility and SEO further. No critical technical debt or risks were identified from the HTML content.
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.
