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

DJ Jan Meruna is a small-scale event entertainment service based in the Czech Republic, offering DJ services, event moderation, streaming, technical event support, and entertainment activities. The website presents a professional and consistent brand image targeting clients organizing weddings, sports events, corporate and private parties, and children's events. The business model is service-oriented with a focus on personalized client engagement and flexibility. Technically, the website uses a modern tech stack including Bootstrap, jQuery, Font Awesome, and Google services such as reCAPTCHA and Tag Manager. The site is mobile optimized with good navigation and content quality. However, no CMS or hosting provider information is evident, and performance is moderate. Accessibility is basic, and SEO practices are adequately implemented. From a security perspective, the site uses HTTPS and integrates Google reCAPTCHA, but lacks visible security headers and explicit privacy or security policies. The WHOIS data is missing, which reduces domain trustworthiness and raises concerns about domain legitimacy. No forms or structured data were detected, limiting data collection and semantic SEO capabilities. Overall, the website is functional and professional but would benefit from improved security practices, explicit privacy and terms policies, and WHOIS transparency to enhance trust and compliance.

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

7 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. 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 business operates in the hospitality sector, specifically event entertainment. It targets a niche market of clients needing DJ and moderation services for various event types. The company leverages social media for marketing and maintains direct contact channels. The business model is straightforward, relying on service delivery rather than product sales. Growth potential may be limited by local market size and lack of broader digital marketing or e-commerce capabilities. Partnerships or subsidiaries are not evident. The company shows moderate trust signals but lacks formal certifications or compliance documentation.

Security posture

The security posture is moderate. HTTPS is used, and Google reCAPTCHA is implemented to protect forms (though no forms were found). The absence of security headers and privacy policies is a gap. No incident response or vulnerability disclosure mechanisms are present. The missing WHOIS data is a significant concern for domain legitimacy. Data protection officer contact or GDPR compliance statements are absent. Overall, the site is not at high risk but could improve security maturity and compliance to reduce potential vulnerabilities and increase user trust.

Recommendations

  1. Implement a comprehensive privacy policy and terms of service pages to ensure legal compliance and user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Verify and improve SSL/TLS configuration to ensure strong encryption and trust indicators in browsers.
  4. Publish a security.txt file or vulnerability disclosure policy to facilitate responsible reporting of security issues.
  5. Enhance accessibility features and structured data markup to improve SEO and user experience.

Technical notes

Notes

The website uses a combination of Bootstrap versions 4.5 and 5 beta CSS, jQuery slim 3.5.1, Popper.js, Font Awesome 4.7, and baguetteBox.js for gallery lightbox functionality. Google Fonts and Google Tag Manager are integrated for typography and analytics. The site is responsive and mobile-friendly with a clean layout and navigation. No CMS or backend technology is detected. Performance is moderate, with potential improvements by consolidating Bootstrap versions and optimizing scripts. No broken links or errors were found. The site lacks structured data and advanced SEO features.
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.
