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

Obchodní akademie a Vyšší odborná škola sociálně právní, Ostrava is a well-established educational institution in the Czech Republic offering secondary and higher vocational education in business, economics, social work, and social pedagogy. The website reflects a medium-sized public institution with a strong regional presence and a broad range of educational programs and extracurricular activities. The institution is funded by the Moravskoslezský kraj regional government, which adds to its credibility and trustworthiness. Technically, the website uses a modern tech stack including jQuery, Nette Framework, and various JavaScript libraries for UI enhancements and user experience. It is hosted on reputable Czech infrastructure with HTTPS enforced and basic security best practices in place. The security posture is solid but could be improved by adding explicit security headers and publishing a security policy or incident response contacts. Privacy compliance is addressed with a cookie consent mechanism and a privacy policy page, both in Czech. Overall, the website is professional, trustworthy, and suitable for its educational audience.

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

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 institution targets students seeking quality education in business and social fields, offering both secondary and higher vocational programs. Its business model is public education funded by regional government, ensuring stable operations. The website demonstrates a clear partnership ecosystem with regional authorities and educational networks. The presence of multiple social media channels and virtual tours indicates active engagement and modern outreach strategies. The domain is newly registered but consistent with the institution's identity, suggesting a recent website launch or renewal. No suspicious patterns or privacy protection obfuscation were detected, supporting legitimacy.

Security posture

The website enforces HTTPS and integrates Google reCAPTCHA v3 to protect forms from automated abuse. Cookie consent is implemented, supporting GDPR compliance. However, explicit security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not detected, which are recommended to enhance security. No vulnerabilities or exposed sensitive data were found in the analysis. The absence of a published security policy or incident response contacts is a gap in transparency and readiness. Overall, the security posture is good but can be strengthened with additional headers and documented policies.

Recommendations

  1. Implement and verify security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a security policy and incident response contact information to improve transparency and preparedness.
  3. Regularly update all third-party libraries and frameworks to avoid known vulnerabilities.
  4. Enhance privacy compliance by detailing data retention policies and user rights clearly on the website.
  5. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on a custom or Nette-based CMS platform using modern JavaScript libraries like jQuery, Flatpickr, Slick slider, and Tippy.js for enhanced user experience. Google Tag Manager and reCAPTCHA v3 are integrated for analytics and security. Hosting is provided by reputable Czech providers with domain registration through REG-INTERNET-CZ and Forpsi name servers. The site is mobile-optimized with responsive design and basic accessibility features. Performance is moderate, with room for optimization. SEO is basic but includes proper meta tags and Open Graph data. No CMS like WordPress or Joomla detected, indicating a custom solution. Overall, the technical infrastructure is solid and appropriate for the institution's needs.
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.
