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

The website www.issho.cz represents Integrovaná střední škola Hodonín, a regional educational institution in the Czech Republic offering vocational and maturitní secondary education along with adult lifelong learning programs. The site provides comprehensive information about study programs, school news, and community activities, targeting students, prospective students, and adult learners. The business model is focused on education and collaboration with private companies for student placement. Technically, the website is built on the CalmCube2 CMS platform, utilizing jQuery, Colorbox, Google Fonts, and Facebook Pixel for tracking. The site is served over HTTPS with a cookie consent mechanism in place, indicating GDPR compliance awareness. The design is professional with good navigation and content relevance, though mobile optimization and accessibility are basic. From a security perspective, the site lacks explicit security headers and detailed privacy or security policies. No WHOIS data was retrievable, which impacts trustworthiness but the website content and domain usage suggest legitimacy. Tracking via Facebook Pixel and imedia.cz retargeting is present, with moderate user tracking levels. No vulnerabilities or critical security issues were detected in the content. Overall, the site scores moderately high on content quality and technical implementation but has room for improvement in security posture and privacy transparency. Strategic recommendations include enhancing security headers, publishing detailed privacy and security policies, and providing clear contact information for incident response and data protection officers.

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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"

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

ISŠ Hodonín operates as a medium-sized educational institution focused on secondary vocational education and adult education in the Czech Republic. Its competitive advantage lies in its collaboration with private companies and regional government support, offering practical training and lifelong learning. The institution targets students seeking skilled trades and maturitní qualifications, as well as adults pursuing further education or retraining. The website reflects a stable market position with consistent branding and active community engagement through news and events. Revenue streams likely include government funding, tuition fees, and grants. The partnership ecosystem includes regional authorities and private sector companies. Growth indicators include recent infrastructure investments and active student participation in events.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and cookie consent mechanisms are implemented, supporting GDPR compliance. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No explicit security or incident response policies are published, and no contact channels for security incidents or data protection officers are provided. The use of third-party tracking pixels introduces moderate user tracking risks. No exposed sensitive data or vulnerabilities were detected in the analyzed content. Overall, the security posture is adequate for an educational website but could be significantly improved by adopting best practices and transparency measures.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance web security.
  2. Publish detailed privacy and security policies, including GDPR compliance statements and data protection officer contact information.
  3. Add explicit contact information for security incident reporting and data protection inquiries.
  4. Improve mobile optimization and accessibility to enhance user experience and compliance with accessibility standards.
  5. Regularly audit third-party scripts and tracking pixels to minimize privacy risks and ensure compliance with data protection regulations.

Technical notes

Notes

The website is built on CalmCube2 CMS with a technology stack including jQuery, Colorbox, Google Fonts, and Facebook Pixel. The site uses HTTPS and has a cookie consent banner, indicating basic privacy compliance. Performance is moderate with no major issues detected. SEO is supported by proper meta tags and Open Graph data. Accessibility and mobile optimization are basic, suggesting opportunities for improvement.

Technical risks include missing security headers and potential privacy concerns from third-party tracking.
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.
