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

Obchodní akademie a Česko - anglická základní škola s.r.o. Ostrava is a private educational institution specializing in secondary education that combines economics and sports, particularly football and coaching. The school targets young athletes and students interested in balancing academic studies with sports training, offering specialized programs such as the Football Academy and Coaching Academy. The institution maintains a niche market position within the Czech Republic's education sector, emphasizing collaboration with FC Baník Ostrava and providing scholarship opportunities for high-performing students. Technically, the website employs a modern JavaScript stack including jQuery, Flatpickr, Google reCAPTCHA v3, and Slick Carousel, integrated within the Nette Framework. The site is mobile-optimized with good SEO practices and includes a cookie consent mechanism compliant with GDPR. However, some security headers are missing, and no explicit incident response or vulnerability disclosure policies are published. From a security perspective, the site enforces HTTPS and uses Google reCAPTCHA to protect forms, indicating a reasonable security posture. The absence of security.txt and incident response contacts suggests room for improvement in transparency and readiness. The WHOIS data is unavailable, likely due to privacy protection, which is common for private educational entities. Contact information is clear and professional, supporting the site's legitimacy. Overall, the website is well-designed, content-rich, and trustworthy, with moderate technical and security maturity. Strategic improvements in security headers, incident response transparency, and accessibility could enhance the site's security and compliance posture.

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.

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 operates in the education sector, focusing on secondary education with a sports specialization. Its competitive advantage lies in combining academic and athletic development, supported by partnerships with local football clubs. Revenue streams likely include tuition fees and scholarships. The target customer segment is young athletes and students in the Ostrava region. Growth indicators include active social media presence and regular updates on admissions and events. The partnership ecosystem includes FC Baník Ostrava and educational platforms like EduPage and Google Classroom. The business model is private and specialized, with a clear focus on niche educational offerings.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforcement and Google reCAPTCHA integration. However, the lack of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No public incident response or vulnerability disclosure policies were found, which limits transparency and preparedness. Data protection practices are supported by a comprehensive privacy policy and cookie consent mechanism, indicating GDPR compliance. No visible vulnerabilities or exposed sensitive data were detected. Overall, the security posture is adequate but could benefit from enhanced header configurations and published security policies.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish a vulnerability disclosure policy or security.txt file to improve transparency and facilitate responsible reporting.
  3. Add incident response contact information to demonstrate readiness and improve trust.
  4. Regularly update third-party libraries and frameworks to mitigate potential vulnerabilities.
  5. Enhance website accessibility features to comply with best practices and improve user experience for all visitors.

Google Tag Manager is used for analytics and marketing tags. The site is mobile-optimized and includes SEO-friendly meta tags and Open Graph data.

Overall, the technical infrastructure supports a professional and functional website experience.
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.
