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

The website info.mojedatovaschranka.cz is an official Czech government portal providing comprehensive information and services related to the Data Mailboxes system, a secure electronic communication platform for interaction with government institutions. Operated by Česká pošta, s.p., the site offers user guidance, multiple secure login methods, and supplementary digital services. The target audience includes Czech citizens and entities requiring official digital communication with state bodies. The site demonstrates a high level of professionalism, clear navigation, and excellent content quality, supporting its role as a trusted government resource. Technically, the website employs modern web technologies including HTML5, CSS3, JavaScript with jQuery, and the Gov Design System framework, ensuring good mobile optimization and accessibility. The site is served over HTTPS with secure login options, although explicit security headers are not visible in the provided data. No cookie consent mechanism was detected, which could be improved for GDPR compliance. The WHOIS data is unavailable, which is unusual but likely due to CZ domain registry policies or privacy measures. From a security perspective, the site enforces HTTPS and offers multiple secure authentication methods, indicating a strong security posture. However, the absence of visible security headers and lack of a published vulnerability disclosure or incident response contact represent areas for enhancement. No vulnerabilities or exposed sensitive data were detected. Overall, the site is secure, trustworthy, and compliant with privacy regulations, though minor improvements are recommended. The overall risk assessment is low, with the site presenting a reliable and professional government service. Strategic recommendations include implementing security headers, adding cookie consent mechanisms, publishing vulnerability disclosure information, and enhancing incident response contact visibility to further strengthen security and compliance posture.

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 serves as a critical digital infrastructure component for the Czech government's electronic communication strategy, operated by Česká pošta, s.p. It holds a strong market position as the official gateway for data mailbox services, providing essential digital communication tools to citizens and organizations. The business model is service-oriented, focusing on government digital service delivery rather than commercial revenue. Key services include user support, secure login options, and supplementary digital services like data vault and postal data messages. The partnership ecosystem includes related government and service domains such as mojdatovaschranka.cz and czechpoint.cz. Growth indicators are implicit in ongoing updates and new service announcements. The portal's operations reflect a mature digital government service with consistent branding and high trust levels.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple secure authentication methods including password, mobile key, and citizen identity. The presence of a dedicated security information page indicates awareness and communication of security policies. No exposed sensitive data or vulnerable libraries were detected in the provided content. However, the absence of explicit security headers (e.g., Content-Security-Policy, X-Frame-Options) and lack of a published vulnerability disclosure or incident response contact are gaps that could be addressed. GDPR compliance is supported by a comprehensive privacy policy, though cookie consent mechanisms are missing. Incident response readiness is not clearly communicated. Overall, the site is secure but could improve transparency and technical security controls.

Recommendations

  1. Implement and enforce security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Add a visible cookie consent banner and detailed cookie policy to enhance GDPR compliance.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Provide clear incident response contact information, including security or abuse email addresses.
  5. Regularly review and update security practices and communicate them transparently to users.

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.
