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

Úřad pro ochranu osobních údajů is the Czech Republic's official Data Protection Authority responsible for enforcing data privacy laws and GDPR compliance. The website serves as a comprehensive resource for the public, professionals, and governmental bodies, offering news, guidance, and regulatory information. The site is professionally designed, mobile-optimized, and provides clear navigation and relevant content in Czech and English. Technically, the website is built on the simploCMS platform, uses modern web standards including HTTPS with a valid SSL certificate, and incorporates accessibility features such as skip links and language selection. The presence of captcha on forms indicates attention to spam prevention. However, explicit security headers are not detected, and no vulnerability disclosure or incident response contacts are published. From a security perspective, the site demonstrates good practices with secure forms and no exposed sensitive data. Privacy compliance is strong, with clear privacy and cookie policies aligned with GDPR. The absence of WHOIS data is likely due to registry privacy policies, but the official .gov.cz domain and consistent branding support legitimacy. Overall, the website presents a low-risk profile with strong business credibility and privacy compliance. Strategic improvements include adding security headers, publishing a security policy and incident response contacts, and implementing a vulnerability disclosure program.

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

6 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 Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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

    • High

      Third-party services without privacy policy

      Detected services: Twitter

      What to do: Document all third-party data sharing in your privacy policy

  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

The Úřad pro ochranu osobních údajů holds a strong market position as the national data protection authority in the Czech Republic. Its business model is regulatory and service-oriented, focusing on oversight, enforcement, and public education. The target audience includes citizens, professionals, and public institutions. The website reflects a mature digital presence with consistent branding and professional content. Partnerships with CMS providers and social media engagement on Twitter enhance its outreach. The lack of advertising and tracking tools aligns with its governmental and privacy-focused mandate.

Security posture

The website's security posture is solid with HTTPS enforced and secure form handling including captcha. However, the absence of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The lack of published incident response contacts or vulnerability disclosure mechanisms limits transparency in security management. Overall, the site is secure but could enhance its security maturity by adopting additional best practices and transparency measures.

Recommendations

  1. Implement and configure security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance contact information with dedicated security and incident response email addresses.
  5. Regularly audit and update CMS and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website uses simploCMS, a modern content management system, with standard web technologies such as HTML5, CSS3, and JavaScript. The site is mobile responsive and includes accessibility features like skip links and language selection. Performance is moderate, with optimized images and structured content. The absence of analytics or tracking scripts indicates a privacy-conscious approach. Hosting details are not explicitly available from the HTML content. Overall, the technical infrastructure supports a professional and secure web presence with opportunities for further optimization and security hardening.
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.
