Spider Dance Company Plzeň is a well-established dance school based in Plzeň, Czech Republic, specializing in modern dance styles such as disco dance and street dance. Operating since 1996, it serves a broad age range of dancers and has a strong presence in national and international dance competitions. The website reflects a professional and community-focused organization with detailed information about classes, teams, events, and achievements. Technically, the site is built on WordPress with Elementor and Yoast SEO, indicating a modern and SEO-friendly infrastructure. Security posture is moderate with HTTPS usage but lacks visible security headers and formal privacy and cookie policies, which are areas for improvement.

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

10 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

  2. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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"

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 dance school operates as a non-profit entity under the local youth center RADOVÁNEK, focusing on dance education and performance. Its competitive success and large membership base position it as a leading dance institution in the Plzeň region. Revenue streams likely include class fees, event participation, and choreography services. The target market includes children, youth, and adults interested in dance. The organization maintains active social media channels to engage its community and promote events. Strategic partnerships appear limited to local organizations. Growth indicators include a large number of dancers and consistent competition participation. The business model emphasizes community engagement and dance education rather than commercial profit.

Security posture

The website employs HTTPS, ensuring encrypted communication, but lacks explicit security headers such as Content Security Policy or HSTS, which could enhance protection against common web attacks. No sensitive data exposure or vulnerable libraries were detected in the HTML content. The absence of privacy and cookie policies indicates a compliance gap with GDPR and related regulations. There is no evidence of an incident response plan or vulnerability disclosure mechanism. The minimal use of analytics and tracking suggests a low privacy risk but also limited user data governance. Overall, the security posture is adequate for a community website but should be improved to meet best practices and regulatory requirements.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to ensure GDPR compliance.
  2. Add security headers such as CSP, HSTS, X-Frame-Options, and X-XSS-Protection to enhance site security.
  3. Establish and publish an incident response and vulnerability disclosure policy to improve transparency and readiness.
  4. Improve accessibility features to comply with WCAG standards and enhance user experience for all visitors.
  5. Regularly audit and update all plugins, themes, and WordPress core to mitigate vulnerabilities and maintain performance.

Key observations

  1. Website is a professionally designed dance school site with rich content about classes, teams, events, and achievements.
  2. No WHOIS data available, which is unusual and reduces domain trust.
  3. No explicit privacy or cookie policies found, which is a compliance gap.
  4. No contact emails or phone numbers explicitly found in the provided HTML snippet.
  5. Social media links to Facebook, Instagram, and YouTube are present and active.
  6. Uses modern WordPress and Elementor technologies with SEO optimization via Yoast.
  7. No signs of adult or questionable content; content is family-friendly and community-oriented.
Technical notes

Notes

The website is built on a modern WordPress platform using Elementor for page building and Yoast SEO for search engine optimization. It uses jQuery and Swiper.js for interactive elements and Koko Analytics for minimal user tracking. The site is mobile responsive with good navigation and structured content. Performance is moderate, with potential for optimization in image loading and caching. The technical stack is standard for community and educational websites, offering ease of maintenance and extensibility. However, the lack of visible security headers and privacy compliance features indicates technical debt in security and regulatory adherence.
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.
