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

The website info.mojedatovaschranka.cz serves as an official government portal providing comprehensive information and services related to 'Datové schránky' (Data Mailboxes), a digital communication system between citizens, businesses, and government institutions in the Czech Republic. Operated by Česká pošta, s.p., the portal offers detailed guidance, multiple secure login methods, technical requirements, and up-to-date news, positioning itself as a trusted and authoritative source for electronic communication with the state. From a technical perspective, the site employs modern web technologies including jQuery, Slick Carousel, and a government design system ensuring good mobile optimization, accessibility, and user experience. The integration of a chatbot enhances user support. While performance is moderate, the site is well-structured and SEO optimized, reflecting a mature digital infrastructure. Security-wise, the portal enforces HTTPS and offers multiple secure authentication methods such as mobile keys and citizen identity logins. However, explicit security headers are not detected, and no vulnerability disclosure or incident response contacts are published, indicating areas for improvement. Privacy compliance is strong with a clear privacy policy and GDPR adherence, though cookie consent mechanisms are absent. Overall, the website demonstrates a high level of professionalism, trustworthiness, and business credibility as a government service portal. The lack of WHOIS data for the subdomain is noted but does not detract from legitimacy given the official branding and content. Strategic recommendations include enhancing security headers, implementing cookie consent, and publishing vulnerability disclosure information to further strengthen security posture and user trust.

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

The portal is positioned as a critical government digital service operated by Česká pošta, s.p., targeting Czech citizens, businesses, and government entities requiring secure electronic communication with state institutions. Its business model is service-oriented, focusing on providing free, reliable, and accessible digital communication infrastructure. The site’s comprehensive content, official branding, and integration with related government services (e.g., Czech POINT, data vault) indicate a well-established ecosystem. Growth indicators include continuous feature updates and user support enhancements. The partnership ecosystem includes related government and digital identity services, reinforcing its authoritative market position.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple secure login options, including certificate-based and mobile key authentication. The presence of a dedicated security information page indicates awareness of security best practices. However, the absence of explicit security headers (e.g., CSP, HSTS) and lack of published incident response or vulnerability disclosure channels represent gaps in security maturity. No exposed sensitive data or vulnerable libraries were detected. Compliance with GDPR is evident through the privacy policy, but cookie consent mechanisms are missing. Overall, the security posture is solid but could benefit from enhanced header policies and transparency in incident handling.

Recommendations

  1. Implement and enforce security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web vulnerabilities.
  2. Introduce a cookie consent banner/mechanism to comply fully with privacy regulations and enhance user trust.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting and improve security transparency.
  4. Provide clear incident response contact information to enable timely communication of security issues.
  5. Regularly audit and update third-party libraries and scripts to ensure no vulnerabilities are introduced.

Technical notes

Notes

The website uses a modern and government-specific design system combined with popular JavaScript libraries like jQuery and Slick Carousel for interactive elements. The site is mobile optimized and accessible, with a clear navigation structure and good SEO practices. Hosting details are not explicitly identified, but the site appears stable and professionally maintained. Performance is moderate, likely due to rich media content such as videos and carousels. There is an opportunity to improve technical robustness by adding security headers and cookie consent mechanisms. The integration of a chatbot indicates a focus on user engagement and support.
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.
