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

The website www.zakaznicka-karta.cz represents the official customer loyalty card service of Česká pošta, the Czech national postal service. It offers users various benefits such as discounts on postal services, the ability to pick up parcels for family members, and partner rewards. The site is well-branded, consistent with Česká pošta's identity, and targets general postal customers in the Czech Republic. The business model is government-operated postal services with a customer loyalty program to enhance user engagement and retention. Technically, the website uses common JavaScript libraries such as jQuery, Slick Carousel, and Magnific Popup, indicating a moderately modern tech stack. The site is mobile optimized and has good SEO practices, although accessibility features are basic. The site loads scripts over HTTPS, but explicit security headers are not detected in the provided data, suggesting room for improvement in security hardening. From a security perspective, the site implements a cookie consent banner and a comprehensive privacy policy compliant with GDPR. However, no explicit security policy, incident response, or vulnerability disclosure information is found. The WHOIS data is unavailable, likely due to CZ NIC privacy restrictions, but the domain and website content strongly indicate legitimacy. No WAF or blocking mechanisms are detected, and the site content is safe with no adult or questionable material. Overall, the website is professionally maintained with a good balance of content quality, technical implementation, and business credibility. Security posture is adequate but could benefit from enhanced headers and transparency on security policies. The domain's legitimacy is supported by consistent branding and official contact details, despite missing WHOIS data.

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

  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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • OWASP A04:2025
      • ASVS V3.4.1

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

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

Česká pošta operates as the Czech Republic's national postal service and offers a customer loyalty card to improve customer retention and satisfaction. The loyalty card provides discounts on postal shipments, convenience features like electronic submission of postal forms, and partner rewards for various consumer goods and services. The website targets general consumers who frequently use postal services, including families and businesses. The business model leverages government backing and a broad national customer base. The partnership ecosystem includes affiliated reward providers accessible via a dedicated subdomain. The site’s content and structure indicate a mature, enterprise-level operation with consistent branding and clear communication channels. Growth indicators include digital integration with mobile apps and ongoing updates to partner offers.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is used for all resources, and a cookie consent mechanism is implemented, supporting GDPR compliance. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options are detected, which are recommended to mitigate common web vulnerabilities. No incident response or vulnerability disclosure information is publicly available, which limits transparency. The absence of exposed sensitive data or vulnerable libraries is positive, but continuous monitoring and security audits are advised. The site lacks a published security policy or contact channels for security incidents, which could improve trust and responsiveness. Overall, the security posture is adequate for a government service but can be enhanced with best practices and transparency.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a clear security policy and incident response plan accessible to users.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Enhance accessibility features to meet WCAG standards for broader compliance.
  5. Regularly audit third-party scripts and dependencies to mitigate supply chain risks.

Technical notes

Notes

The website uses a standard front-end stack with jQuery and popular UI libraries like Slick Carousel and Magnific Popup, indicating a conventional but effective approach to user interface design. The site is mobile optimized and includes responsive design elements. Performance is moderate, with no explicit indicators of slow loading but no advanced optimization techniques detected. The absence of a detected CMS suggests a custom or proprietary platform. SEO is supported by proper meta tags and structured navigation. However, the lack of detected security headers and limited accessibility features highlight areas for technical improvement. Hosting details are not disclosed, and no CDN usage is evident from the data provided.
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.
