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

  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"

    • 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';…

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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

Leaked records that mention cr-sei.cz, from OffSeq Breach.

No leaked records found

Breach holds no records for cr-sei.cz right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

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

Business context

Business profile

SEI operates as a government agency within the energy sector, providing regulatory oversight and inspection services. Its business model is non-commercial, focused on compliance enforcement and public service. The website content and structure indicate a mature digital presence with regular updates, official announcements, and educational resources. The agency maintains social media channels on Facebook and LinkedIn, enhancing outreach. The absence of WHOIS data is unusual but likely due to CZ.NIC policies for government domains. The site does not engage in advertising or affiliate marketing, emphasizing its public service role.

Security posture

The site enforces HTTPS with a strong SSL configuration, ensuring secure communication. No security headers were detected in the HTML source, which is a potential area for improvement. There is no visible security policy or incident response contact information, which could enhance transparency and trust. No vulnerabilities or exposed sensitive data were found. The site does not appear to collect personal data via forms on the homepage, reducing attack surface. Overall, the security posture is good but could benefit from additional headers and published security policies.

Recommendations

  1. Implement standard security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with EU cookie laws and GDPR requirements.
  3. Publish a dedicated security policy and incident response contact information to improve transparency and facilitate vulnerability reporting.
  4. Consider adding a security.txt file to provide a standardized channel for security researchers to report issues.
  5. Investigate the absence of WHOIS data and ensure domain registration information is accurate and publicly available as appropriate for government domains.

Technical notes

Notes

The website is built on WordPress 6.4.5, utilizing modern technologies including jQuery 3.7.1, Bootstrap framework, and Font Awesome icons. It uses several plugins such as WPSSO Core for structured data, File Away for file management, and Quick Page/Post Redirect for URL management. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with no major issues detected. SEO is supported by proper meta tags, Open Graph, Twitter cards, and JSON-LD structured data. The site does not use third-party analytics or tracking services visibly, indicating a privacy-conscious approach. Hosting provider details are not explicitly found in the 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.
