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

The website kredit-ds.cz/payment is an official service portal operated by Česká pošta, the Czech postal service, providing a platform for users to top up credit for their data mailboxes. The site targets Czech individuals and businesses who use electronic government communication services. It offers payment options including payment by card and domestic bank transfer, with clear instructions and official branding. The website is well-structured, mobile-optimized, and provides essential contact information, enhancing user trust and accessibility. Technically, the site is built using modern web technologies including React and Material-UI, ensuring a responsive and user-friendly interface. While performance is moderate, the site lacks some advanced SEO and accessibility features. Security practices include HTTPS and form validation, but the absence of security headers and cookie consent mechanisms indicates room for improvement in compliance and security hardening. From a security perspective, no critical vulnerabilities or malware indicators were found. However, the lack of WHOIS data due to privacy protection limits domain registration transparency. The site aligns with GDPR requirements through its privacy policy, but cookie consent is missing. Overall, the site demonstrates a solid security posture for a government service but should enhance transparency and compliance features. The overall risk assessment is low, with recommendations focusing on improving security headers, cookie consent, and publishing security policies to strengthen user trust and regulatory compliance. The site’s legitimacy is high given its association with Česká pošta and consistent branding.

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.

Priority findings

8 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

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

Česká pošta operates this service as part of its government mandate to facilitate electronic communication via data mailboxes. The business model is service-oriented, focusing on payment processing for credit top-ups. The company leverages partnerships with payment gateways such as postaonline.cz to handle transactions. The target market includes government entities, businesses, and individuals requiring official electronic document delivery. The site’s integration with official postal services and clear contact channels supports a strong market position in the Czech Republic. Growth potential lies in expanding digital government services and enhancing user experience. Competitive advantages include official government backing, trusted brand recognition, and integration with national e-government infrastructure. Revenue streams are likely derived from payment processing fees and service charges. The partnership ecosystem is limited but focused on payment processing and government compliance. Strategic observations suggest continued investment in digital transformation and compliance will sustain market leadership.

Security posture

The website exhibits a moderate security maturity level. HTTPS is enforced, and form inputs have validation, reducing common attack vectors. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options weakens defense-in-depth. No exposed sensitive data or vulnerable libraries were detected in the provided content. The lack of a published security policy or incident response plan reduces transparency and preparedness. Compliance with GDPR is partially demonstrated through a privacy policy, but missing cookie consent mechanisms indicate gaps. No vulnerability disclosure or security.txt files were found, limiting external reporting channels. Incident response readiness appears minimal based on available information. Overall, the security culture is functional but could benefit from formalized policies and enhanced technical controls to mitigate risks and improve user trust.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to strengthen security posture.
  2. Add a cookie consent banner/mechanism to ensure GDPR compliance and user transparency.
  3. Publish a detailed security policy and incident response plan accessible to users.
  4. Introduce a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features and SEO optimization to improve user experience and reach.

Technical notes

Notes

The website is built on a modern React framework with Material-UI components, providing a responsive and visually consistent user interface. The use of deferred JavaScript loading indicates performance optimization efforts. However, no advanced CMS or hosting provider details were detected. The site shows moderate performance and good mobile optimization but lacks advanced SEO meta tags and accessibility attributes. Technical debt appears low, but improvements in security headers and privacy compliance are needed. The infrastructure supports the business model effectively but could be modernized further with enhanced analytics and monitoring tools.
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.
