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

Český telekomunikační úřad (ČTÚ) is the Czech Republic's national regulatory authority overseeing telecommunications, postal services, and radio spectrum management. The website serves as an official government portal providing regulatory information, public consultations, consumer guidance, and digital service facilitation. It targets consumers, businesses, and government entities within the Czech Republic. The site is well-structured, professionally designed, and compliant with privacy and cookie regulations, reflecting a mature digital presence. Technically, the website is built on Drupal CMS with a combination of jQuery, Bootstrap, and other common web libraries. It integrates Google Fonts and Google Maps API, and uses a cookie consent mechanism aligned with GDPR requirements. Performance is moderate with good mobile optimization and accessibility features. Security posture is strong with HTTPS enforced and no visible vulnerabilities, though security headers could be enhanced. The WHOIS data is missing, which is unusual but may be due to registry policies of CZ.NIC. Despite this, the domain's .gov.cz suffix and consistent official content strongly indicate legitimacy. Contact information including official emails, phone numbers, and physical address are clearly provided, enhancing trust. Overall, the website represents a credible, secure, and professional government regulatory authority portal with good 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.

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

ČTÚ holds a critical position as the national regulator in telecommunications and postal sectors in the Czech Republic. Its business model is government regulatory oversight, licensing, and public service provision. The website supports transparency through published reports, public consultations, and open data initiatives. The organization leverages partnerships with EU bodies and international spectrum groups, indicating active engagement in regional regulatory frameworks. The presence of campaigns and consumer support tools suggests a focus on consumer protection and market development. The site’s content and structure reflect a large, established entity with a broad mandate and significant public interface.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent compliance, and no exposed sensitive data. Use of updated libraries and absence of known vulnerabilities in the visible code is positive. However, explicit security headers like Content-Security-Policy and X-Frame-Options are not detected and should be implemented to enhance protection against common web attacks. The site lacks a public vulnerability disclosure or security.txt file, which could improve transparency and incident response. Incident response contact emails related to security are present, indicating some readiness. Overall, the security maturity is good but can be improved with additional headers and formal vulnerability disclosure mechanisms.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Upgrade jQuery library to a more recent version to mitigate legacy vulnerabilities.
  3. Publish a security.txt file or vulnerability disclosure policy to facilitate responsible reporting.
  4. Enhance WHOIS transparency if possible or provide official domain registration details on the website.
  5. Continue regular audits of third-party scripts and maintain GDPR compliance with clear data retention policies.

Technical notes

Notes

The website uses Drupal CMS with a classic LAMP stack implied. It employs jQuery 1.12 and jQuery UI for UI components, along with Bootstrap for responsive design and Slick Carousel for sliders. Google Fonts and Google Maps API are integrated for enhanced UI and mapping features. The site loads multiple CSS and JS assets efficiently but uses some older libraries that could be modernized. Accessibility and SEO optimizations are evident through ARIA roles, language tags, and meta viewport settings. Performance is moderate, with room for improvement in script optimization and caching strategies. The technical infrastructure supports a large government portal with complex navigation and content management needs.
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.
