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

4 findings rated critical or high. Fix these first.

  1. 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"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Top Vision operates in the education sector focusing on professional development for managers and corporate teams. Its business model combines B2B tailored training solutions and B2C open courses. The company benefits from its affiliation with EDUA Group and subsidiaries, enhancing market reach and service diversity. Revenue streams likely include course fees, corporate contracts, and e-learning subscriptions. The target audience is primarily Czech-speaking professionals and companies seeking skill enhancement. The presence of multiple certifications and awards supports a competitive advantage. Strategic partnerships with payment gateways and marketing platforms indicate a mature operational ecosystem. Growth indicators include active course offerings, frequent updates, and a strong online presence.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and integration of Google reCAPTCHA to mitigate automated abuse. Cookie consent management aligns with GDPR requirements, enhancing privacy protection. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options suggests room for improvement. Incident response and vulnerability disclosure mechanisms are not publicly visible, which could be enhanced to improve security transparency. Overall, the site balances usability and security effectively but should consider adopting additional security headers and publishing a security.txt file.

Recommendations

  1. Implement HTTP security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection to strengthen defense-in-depth.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve incident response readiness.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance accessibility features to meet higher compliance standards and improve user inclusivity.
  5. Maintain and update cookie consent mechanisms in line with evolving privacy regulations and best practices.

Technical notes

Notes

The website uses a combination of jQuery and various plugins (BXSlider, Select2, ICheck) alongside modern analytics and marketing tools such as Google Tag Manager, Hotjar, and Limetalk live chat. The presence of Google reCAPTCHA v3 indicates proactive bot mitigation. The site loads multiple CSS stylesheets and scripts asynchronously to optimize performance. Mobile responsiveness is addressed with viewport meta tags and conditional CSS. The site lacks a detectable CMS, suggesting a custom or proprietary platform. Performance is moderate with room for optimization, especially in script loading and caching. The technical stack is stable but could benefit from modernization by reducing legacy jQuery dependencies and adopting newer frameworks or SPA technologies for enhanced user 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.
