Risk levelHigh

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

The website www.jak-spravne-psat.cz is an educational platform dedicated to supporting proper handwriting skills in children, primarily targeting parents and educators in the Czech Republic. It is backed by CENTROPEN, a.s., a company that appears to support the project both financially and organizationally. The site offers practical advice, instructional content, and an online advisory service to help children develop correct writing habits. Technically, the website uses modern web fonts, Google services such as reCAPTCHA and YouTube embeds, and implements a cookie consent mechanism, indicating a moderate level of digital maturity. However, the absence of WHOIS data and lack of visible privacy and terms of service pages suggest gaps in transparency and compliance. Security posture is generally good with HTTPS and reCAPTCHA usage, but the lack of security headers and formal policies reduces the overall security maturity. Overall, the website is trustworthy and professional in content and design but would benefit from enhanced compliance documentation and improved security headers to strengthen user trust and regulatory adherence.

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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  4. 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"

      • CWE-319
      • 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

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 · found on this site
  • 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 project is positioned as a niche educational resource focused on handwriting skills for children, supported by CENTROPEN, a.s., a company likely operating in the stationery or educational supplies sector. The business model revolves around providing free educational content and advisory services online, possibly as part of a corporate social responsibility initiative or brand-building effort by CENTROPEN. The target audience includes parents and educators of preschool and school-age children. The website's market position is specialized and localized to the Czech language and region. There is no evidence of direct monetization such as e-commerce or advertising, suggesting the site serves primarily as an informational and support platform. The partnership ecosystem includes CENTROPEN and social media presence on Facebook. Growth indicators are not explicit, but the presence of updated content and advisory services indicates ongoing maintenance and engagement.

Security posture

The website enforces HTTPS and uses Google reCAPTCHA to protect form submissions, which are positive security practices. However, no security headers such as Content-Security-Policy, X-Frame-Options, or X-Content-Type-Options were detected, which are recommended to mitigate common web vulnerabilities. The absence of a published privacy policy and terms of service pages indicates compliance gaps, particularly regarding GDPR requirements. No incident response or security contact information is provided, limiting the ability to report or respond to security issues. No vulnerabilities or exposed sensitive data were identified in the provided content. Overall, the security posture is moderate but could be significantly improved by implementing recommended headers, publishing compliance documents, and providing clear security contacts.

Recommendations

  1. Publish a comprehensive privacy policy page to improve GDPR compliance and user trust.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add terms of service and security policy pages to clarify user rights and security practices.
  4. Provide clear contact information for security incidents and data protection inquiries.
  5. Regularly audit WHOIS data and ensure domain registration information is accurate and publicly available to enhance transparency.

Technical notes

Notes

The website uses a modern tech stack including Google Fonts, YouTube Player API, and Google reCAPTCHA, indicating integration with popular and reliable third-party services. The site is mobile-optimized with responsive design and good navigation clarity. Performance is moderate, with no explicit indicators of slow loading or technical debt. The absence of a detected CMS suggests a custom or lightweight platform. No hosting provider information was found. Accessibility features are basic but present. SEO optimization is good, supported by proper meta tags and structured data (JSON-LD). The site could benefit from enhanced technical security measures and more comprehensive compliance documentation to reduce risks and improve user confidence.
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.
