Risk levelLow

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

Česká pošta operates the PoštaOnline website as the official online portal for the Czech national postal service. The site provides a comprehensive suite of postal and logistics services including parcel tracking, branch location, online parcel sending, and business-oriented services. It also integrates eGovernment services and an eShop for postal goods, targeting both general public and business customers within the Czech Republic. The website is well-branded, consistent, and professionally designed, reflecting its position as a large enterprise and national postal operator. Technically, the site is built on the Liferay CMS platform, utilizing common JavaScript libraries such as jQuery and SlickNav for UI components. The site is mobile-optimized, accessible, and performs moderately well. Security is enforced through HTTPS and cookie consent mechanisms, though some advanced security headers are missing. The site integrates Google Analytics for user tracking with a GDPR-compliant cookie banner. From a security perspective, the site demonstrates good practices with encrypted connections and session management. However, the absence of WHOIS data limits domain registration trust analysis. No critical vulnerabilities or exposed sensitive data were detected. Privacy policies and cookie information are clearly presented, supporting GDPR compliance. Overall, the site is trustworthy and safe for general users. Strategically, the site should improve domain registration transparency, add security headers, and publish explicit security policies and incident response contacts to enhance trust and compliance. These steps will strengthen the security posture and business credibility further.

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

3 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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 holds a dominant position as the national postal operator in the Czech Republic, serving both individual and corporate customers. Its business model combines traditional postal services with digital transformation initiatives, offering online parcel management, eGovernment integration, and eCommerce capabilities. The company leverages partnerships with financial institutions and job portals to extend service offerings. The website reflects a mature digital presence aligned with enterprise standards. Growth indicators include diversified online services and integration with government digital infrastructure. The partnership ecosystem includes banks, payment services, and recruitment platforms, enhancing customer reach and service breadth.

Security posture

The website exhibits a mature security posture with mandatory HTTPS encryption and cookie consent mechanisms aligned with GDPR. Session management includes auto-extension and expiration redirects, reducing session hijacking risks. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options represents a moderate security gap. No public vulnerability disclosure or incident response information is provided, limiting transparency. The lack of WHOIS data reduces domain trust from a registration perspective but does not impact operational security. Overall, the site is secure for users but could improve transparency and header configurations to meet higher security standards.

Recommendations

  1. Implement and publish a security.txt file and incident response contact information to improve vulnerability disclosure transparency.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Investigate and resolve the missing WHOIS data issue to improve domain registration transparency and trustworthiness.
  4. Enhance contact information visibility by including verified company contact emails and phone numbers on the main site or contact pages.
  5. Continue monitoring and updating cookie and privacy policies to maintain GDPR compliance and user trust.

Technical notes

Notes

The website is built on the Liferay CMS platform, leveraging JavaScript libraries such as jQuery, SlickNav, and Cycle2 for UI and interactive elements. The site uses modern web standards with UTF-8 encoding and responsive design for mobile optimization. Performance is moderate with some potential for improvement in load times. Accessibility features are implemented at a good level, including language attributes and ARIA roles. SEO is supported by canonical links and meta descriptions. The site lacks some advanced security headers which could be added to reduce risk. Hosting provider details are not explicitly identified from the content. Overall, the technical infrastructure is solid but could benefit from modernization in security header implementation and performance tuning.
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.
