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

6 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

      Third-party services without privacy policy

      Detected services: Google Analytics, Facebook, LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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 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';…

  3. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • High

      No DMARC record found

      DMARC provides email authentication and reporting

      What to do: Add DMARC record: "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com"

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

ScioŠkoly holds a strong market position as an innovator in Czech education, supported by official accreditation and positive feedback from parents and students. Their competitive advantage lies in their revolutionary curricula and focus on skills relevant for future challenges. The organization targets families seeking alternative education models and operates a network of schools and projects that complement their core educational offerings. Partnerships with related domains enhance their ecosystem, including application portals, research, and extracurricular activities. Growth indicators include expanding school locations and active social media engagement. Strategic observations highlight the importance of maintaining innovation leadership and expanding digital capabilities.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and a cookie consent mechanism aligned with GDPR requirements. However, there is no visible security policy, incident response information, or vulnerability disclosure program, which are important for transparency and trust. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of Google Tag Manager is properly consented. Recommendations include implementing security headers, publishing security policies, and establishing incident response contacts to enhance security posture and compliance.

Recommendations

  1. Implement comprehensive security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  2. Publish a clear security policy and incident response information on the website.
  3. Establish and publicize a vulnerability disclosure program or security.txt file.
  4. Enhance transparency by providing data retention policies related to analytics and cookies.
  5. Continue to maintain and improve mobile optimization and accessibility features.

Technical notes

Notes

The website is built on a modern technology stack including HTML5, CSS3, JavaScript with jQuery and Bootstrap frameworks, and uses Umbraco CMS as indicated by asset handlers and media references. It integrates Google Tag Manager for analytics and marketing. The site is mobile-optimized with responsive design and good accessibility practices. Performance is moderate, with some room for optimization. The technical implementation supports a professional user experience with clear navigation and multimedia content. Opportunities exist to improve security headers and formalize security and privacy documentation.
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.
