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

The website sipo.cz represents the SIPO payment tool operated by Česká pošta, the Czech national postal service. It offers a consolidated payment solution for regular bills such as utilities, rent, and broadcasting fees, simplifying payment processes for the general public in the Czech Republic. The site is well-branded, consistent with the parent company, and provides clear information about the service and contact details. The domain is long-established, dating back to 2001, aligning with the service's history and legitimacy. From a technical perspective, the website uses standard web technologies including HTML5, CSS, and JavaScript. It is mobile-optimized and provides a good user experience with clear navigation and professional design. However, there is no explicit CMS or advanced frameworks detected, and some accessibility and SEO optimizations are basic. Security headers and explicit security policies are not visible in the provided content, though HTTPS usage is implied. No signs of tracking or advertising scripts were found, indicating a privacy-conscious approach. Security posture is moderate with no critical vulnerabilities detected in the content. The site links to comprehensive privacy and cookie policies hosted on the official Czech Post domains, indicating GDPR compliance. Contact information is clearly provided, but there is no visible incident response or vulnerability disclosure information. The domain WHOIS data is consistent with the business claims, enhancing trustworthiness. Overall, the website is a trustworthy, government-backed payment service platform with good content quality and business credibility. Strategic improvements could focus on enhancing security headers, adding explicit security and incident response policies, and implementing cookie consent mechanisms to further strengthen privacy compliance and security 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.

Priority findings

7 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

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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

      • ASVS V3.4.3

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

SIPO is positioned as a key national payment consolidation service under Česká pošta, targeting the general Czech population who need to manage multiple regular payments efficiently. Its competitive advantage lies in its government backing, long operational history, and integration with postal services. The business model revolves around facilitating payments without requiring internet banking, appealing to a broad demographic including less tech-savvy users. Revenue streams likely include service fees and partnerships with utility providers and banks. The partnership ecosystem includes official Czech Post domains and related payment service sites. Growth indicators include sustained domain age and consistent branding. The company operates in the government sector with a large organizational size, emphasizing reliability and trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS usage and no visible exposed sensitive data or vulnerable libraries. However, the absence of explicit security headers and incident response information suggests room for improvement. GDPR compliance is supported through linked privacy policies, but cookie consent mechanisms are not evident. The lack of a vulnerability disclosure policy or security.txt file indicates limited transparency in security incident handling. Overall, the security culture appears cautious but could benefit from formalized policies and enhanced technical controls to mitigate risks and improve user trust.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  2. Add a dedicated security policy and incident response page to improve transparency and readiness.
  3. Introduce a cookie consent banner/mechanism to comply fully with GDPR cookie requirements.
  4. Conduct regular security audits of third-party scripts and dependencies to prevent vulnerabilities.
  5. Enhance accessibility features to meet WCAG standards and improve user inclusivity.

Technical notes

Notes

The website uses a straightforward technology stack with HTML5, CSS, and JavaScript, without detectable advanced frameworks or CMS platforms. The site is mobile-optimized and provides a good user experience with clear navigation and professional design. Performance is moderate, with no explicit indicators of slow loading or technical debt. The absence of advanced analytics or tracking scripts suggests a privacy-focused approach but also limits marketing insights. Hosting provider details are not available from the provided data. Opportunities exist to modernize the tech stack, improve SEO and accessibility, and implement stronger security controls to reduce technical risks.
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.
