ISŠ Vysoké nad Jizerou is a well-established vocational secondary school in the Czech Republic specializing in automotive, logistics, and related technical education. The institution offers a variety of study programs including both vocational and maturitní (graduation) courses, complemented by practical training such as welding courses, driving licenses, and professional internships. The school maintains a strong regional presence with a history dating back to 1998 for the domain and over 100 years of educational tradition. The website reflects a medium-sized educational institution targeting students and the local community with clear navigation and relevant content. Technically, the site uses modern front-end libraries and a CMS platform (Cliquo), with good mobile optimization and moderate performance.

Privacy compliance is partial, with a privacy policy present but no cookie consent mechanism. Overall, the site is professional, trustworthy, and safe for general audiences.

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

9 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"

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

      Missing X-Frame-Options header

      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
      • 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 in the education sector with a focus on vocational training for automotive and logistics industries. Its business model is centered on providing secondary education and practical skills development. The institution leverages partnerships with local businesses and industry players to enhance student training and employability. The website's external links and partner logos indicate a collaborative ecosystem supporting its educational mission. The school targets prospective students and their families, offering clear information on courses, benefits, and admissions. Growth indicators include active updates, events, and a digital presence on social media platforms. The business credibility is reinforced by consistent branding, transparent contact information, and a long-standing domain registration.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces protection against common web attacks. No visible vulnerabilities or exposed sensitive data were detected. The site lacks a published security policy or incident response contacts, which are important for transparency and trust. Privacy compliance is partial, with a privacy policy present but no cookie consent banner, potentially exposing the institution to regulatory risks under GDPR. The use of third-party scripts is limited and appears safe, but ongoing monitoring is recommended. Overall, the security posture is adequate for an educational website but can be improved with additional controls and transparency.

Recommendations

  1. Implement security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  2. Add a cookie consent mechanism to comply with EU privacy regulations and improve user transparency.
  3. Publish a dedicated security policy and incident response contact information to build trust and readiness.
  4. Enhance accessibility features to meet WCAG standards and improve user experience for all visitors.
  5. Regularly audit and update third-party libraries and scripts to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built on the Cliquo CMS platform, utilizing jQuery and Slick Carousel for interactive elements, and FontAwesome for icons. Google Fonts are used for typography. The site is mobile responsive with good navigation clarity and consistent branding. Performance is moderate, with some room for optimization. SEO is basic with proper meta tags and Open Graph data, but could be enhanced with richer structured data and sitemap improvements. No advanced analytics or tracking tools were detected, indicating minimal user tracking. The technical infrastructure supports the business needs effectively but could benefit from modernization and enhanced security configurations.
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.
