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

8 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

    • High

      Missing Strict-Transport-Security header

      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

The school operates in the education sector, focusing on language learning services primarily in the Czech Republic. Its market positioning is that of a reputable local institution with international affiliations, catering to a diverse audience including young learners, adults, and corporate clients. The business model revolves around course offerings with potential revenue streams from tuition fees for various programs. The presence of a Facebook page and Google site verification indicates active digital marketing efforts. Partnerships with design and website development firms are evident, enhancing brand presentation. Growth indicators include a variety of courses and active news updates. The company maintains a clear contact infrastructure and transparent communication channels, supporting customer engagement and trust.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is properly implemented, ensuring encrypted communications. Cookie consent and tracking opt-in/out mechanisms are in place, reflecting privacy awareness and GDPR compliance. Form inputs have client-side validation to prevent malformed data submissions. However, the absence of explicit security policies, incident response contacts, or vulnerability disclosure mechanisms limits transparency and preparedness. No critical vulnerabilities or exposed sensitive data were detected in the analysis. The use of third-party tracking scripts necessitates ongoing monitoring for potential risks. Overall, the security posture is adequate for the business type but could be enhanced by publishing security policies and incident response information.

Recommendations

  1. Publish a clear security policy and incident response contact information on the website.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection.
  3. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  4. Enhance mobile optimization and accessibility features to improve user experience across devices.
  5. Verify and update WHOIS registration details to improve domain legitimacy and trust signals.

Technical notes

Notes

The website uses a custom CMS platform with modern front-end technologies including HTML5, CSS3, JavaScript, and jQuery-based bxSlider for interactive elements. Google Tag Manager and Facebook Pixel are integrated for analytics and marketing purposes. The site loads external fonts from Google Fonts and uses asynchronous script loading to optimize performance. Mobile optimization is basic but functional, with responsive meta tags present. SEO is supported by proper meta tags, canonical links, and structured navigation. Performance is moderate with room for improvement in loading speed and accessibility compliance. No major technical debt or deprecated technologies were identified, but the site could benefit from enhanced security headers and improved mobile responsiveness.
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.
