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. 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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 operates in a niche segment of the energy sector, focusing on sCO2 technology which is an emerging field for efficient energy systems. Their business model appears to be centered on technology development and knowledge dissemination rather than direct product sales. The domain age and registration details align with the company's recent establishment in 2019. The website content is consistent with the Czech Republic location and energy industry focus. There is no evidence of partnerships or subsidiaries from the website content. The company maintains GDPR compliance and uses minimal tracking analytics, indicating a privacy-conscious approach.

Security posture

The website enforces HTTPS and has domain transfer protection, which are positive security indicators. However, no advanced security headers were detected, and there is no published security policy or incident response contact information. The use of popular WordPress plugins and themes suggests a need for regular updates to mitigate vulnerabilities. The cookie consent mechanism and privacy policy demonstrate compliance with GDPR. No vulnerabilities or exposed sensitive data were found in the analysis. Overall, the security posture is moderate but could be enhanced by implementing recommended headers and formal security documentation.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance protection against common web attacks.
  2. Enable DNSSEC for the domain to improve DNS security and prevent spoofing.
  3. Publish a dedicated security policy and provide clear incident response contact channels to improve transparency and trust.
  4. Consider adding a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance accessibility features and conduct regular security audits to maintain a strong security posture.

Notes

The website is built on WordPress with the Astra theme and Elementor page builder, supplemented by plugins such as Smart Slider 3, Contact Form 7, and Complianz GDPR. The tech stack is modern and widely supported, facilitating good performance and mobile responsiveness. Hosting appears to be provided by Ignum, a Czech hosting provider, consistent with the domain's DNS servers. The site uses Google Fonts for typography and minimal tracking via Burst Statistics. Performance is moderate with no major issues detected. SEO and accessibility are basic to good, with room for improvement in accessibility compliance. Overall, the technical infrastructure is solid for a small technology-focused business.
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.
