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

Základní škola Slovan Kroměříž is a primary educational institution serving the local community in the Czech Republic. The website provides information about the school, its services including cafeteria and after-school programs, and links to official partners and projects. The site targets students, parents, and local stakeholders with relevant educational content and announcements. Technically, the website uses modern web technologies such as Bootstrap, Google Analytics, and Google Tag Manager, ensuring a responsive and user-friendly experience. However, some security best practices like security headers and privacy compliance mechanisms are missing. The security posture is moderate with HTTPS enabled but lacking advanced protections. The absence of WHOIS data limits domain trust assessment, but the website content and external references support legitimacy. Overall, the site is professional and trustworthy but would benefit from enhanced privacy and security measures.

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

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

    • 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      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
  • 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 school operates as a local educational entity with a focus on primary education. It maintains partnerships with regional organizations and participates in EU-supported projects, indicating active community engagement and funding sources. The business model is typical for public or municipal schools, relying on government or local funding. The website serves as an information portal rather than a commercial platform, with no evident revenue streams beyond educational services. The presence of official contact details and certifications supports credibility. Growth indicators are limited due to the nature of the institution, but the digital presence is well-maintained. The partnership ecosystem includes local government and health-related projects, enhancing the school's community role.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and no sensitive data is exposed in the HTML. However, the lack of security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No incident response or security policy information is provided, indicating limited transparency in security governance. The absence of privacy and cookie policies is a compliance gap under GDPR. Tracking via Google Analytics is present without visible consent mechanisms, which may pose privacy risks. Overall, the security posture is adequate for an informational site but requires improvements to meet modern compliance and security standards.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie consent banner to ensure GDPR compliance.
  2. Add essential security headers (Content-Security-Policy, X-Content-Type-Options, X-Frame-Options) to enhance protection against web vulnerabilities.
  3. Conduct regular security audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Establish and communicate an incident response plan and security policy to improve transparency and readiness.
  5. Improve accessibility features to ensure compliance with accessibility standards and enhance user experience.

Technical notes

Notes

The website is built using Bootstrap framework with integration of Google Fonts, FontAwesome icons, and jQuery-based Slick Carousel for UI components. Google Analytics and Google Tag Manager are used for visitor tracking. The site is mobile responsive and well-structured with proper meta tags for SEO and social media sharing (Open Graph and Twitter cards). Performance is moderate with asynchronous loading of analytics scripts. No CMS is explicitly detected, suggesting a custom or static site build. Hosting provider details are not available from the data. The site lacks some modern security headers and privacy compliance features, which are technical debt areas. Overall, the technical infrastructure supports a stable and user-friendly experience but could be modernized with enhanced security and privacy controls.
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.
