Risk levelMedium

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

Jazyková škola Spěváček is a Czech language school based in Prague offering group, individual, and corporate language courses across multiple locations. The website presents a professional and consistent brand image with a focus on language education services. The business appears established since at least 2014, supported by structured data and social media presence. Technically, the site is built on WordPress using Elementor and Yoast SEO, with integration of Google Tag Manager and Cookiebot for analytics and privacy compliance. Security posture is adequate with HTTPS and cookie consent, but lacks visible security headers and explicit privacy policy documentation. Overall, the site is trustworthy and well-positioned in its local market, though improvements in privacy transparency and security hardening are recommended.

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

3 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';…

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 company targets language learners in Prague, offering a variety of course formats to individuals and corporate clients. Its business model relies on educational services with potential revenue from course fees and related e-commerce. The presence of partner domains suggests an ecosystem supporting online courses and materials. The company leverages multiple marketing and analytics tools to optimize user engagement and advertising effectiveness. Growth indicators include a multi-location presence and active social media channels. Strategic partnerships with related educational platforms enhance market reach.

Security posture

The website enforces HTTPS and uses a cookie consent mechanism, indicating awareness of privacy and security requirements. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth. No security.txt or incident response contact information is found, limiting transparency for vulnerability reporting. The use of multiple third-party analytics and marketing tools increases the attack surface and data sharing risks. Overall, the security maturity is moderate but could be improved by implementing recommended headers, publishing privacy policies, and establishing clear incident response channels.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Publish a comprehensive privacy policy and terms of service accessible from the homepage to improve legal compliance and user trust.
  3. Add a security.txt file and provide explicit contact information for security incidents to facilitate responsible vulnerability disclosure.
  4. Review and minimize third-party tracking to reduce privacy risks and improve GDPR compliance.
  5. Regularly audit and update all third-party libraries and plugins to mitigate vulnerabilities.

Technical notes

Notes

The website uses a modern WordPress CMS with Elementor page builder and Yoast SEO plugin, indicating a mature and maintainable technical infrastructure. Google Tag Manager and Cookiebot are integrated for analytics and cookie management. The site loads external fonts from Google Fonts and uses jQuery. Performance is moderate with some optimization opportunities. Mobile responsiveness is good, but accessibility features are basic. No hosting provider details were found. The site could benefit from enhanced accessibility and performance tuning to improve user experience and SEO further.
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.
