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

LED Studio is a well-established Czech company specializing in the supply and servicing of large-format LED display technologies for advertising, sports, and entertainment sectors. Founded in 2007, it holds a leading market position in the Czech Republic, offering a broad product portfolio including indoor and outdoor LED screens, LED mantinels, LED rings, and rental solutions. The company supports its clients with financing options, warranty services, and professional consulting. Technically, the website employs standard web technologies such as HTML5, CSS, JavaScript, and jQuery, with integrations like Google Analytics and Google Maps API. While the site is functional and professionally designed, it lacks advanced security headers and explicit privacy or cookie policies, which are critical for GDPR compliance and user trust. The security posture is moderate, with room for improvement in headers and form protections. Overall, the domain registration data aligns well with the business claims, supporting legitimacy. Strategic improvements in privacy compliance and security practices would enhance trust and reduce risk.

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

11 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

LED Studio operates primarily in the technology sector, focusing on LED display solutions for B2B clients in advertising, sports venues, and entertainment. Its competitive advantage lies in its comprehensive product range, financing options, and professional service support. The company leverages partnerships with related service providers and software vendors, as evidenced by multiple linked partner domains. The business model is centered on direct sales, rentals, and after-sales services, targeting medium-sized enterprises and organizations requiring LED technology. The website content and references indicate a stable market presence with ongoing projects and case studies, suggesting steady growth and industry recognition.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is used, but no explicit security headers such as Content Security Policy, HSTS, or X-Frame-Options are detected, which are important for mitigating common web attacks. Forms lack visible anti-CSRF tokens, and no vulnerability disclosure or incident response policies are published. Google Analytics is implemented without a visible cookie consent mechanism, raising privacy compliance concerns under GDPR. No exposed sensitive data or known vulnerabilities are evident in the HTML content. The absence of privacy and cookie policies, along with missing security headers, represents compliance and security gaps that should be addressed to improve the overall security posture.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add HTTP security headers including Content Security Policy, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Introduce a security.txt file and vulnerability disclosure policy to enhance incident response readiness.
  4. Enhance form security by adding anti-CSRF tokens and input validation mechanisms.
  5. Regularly update and audit third-party libraries and scripts to mitigate vulnerabilities.

Technical notes

Notes

The website uses a traditional web technology stack with HTML5, CSS, and JavaScript libraries such as jQuery and Nivo Slider for UI components. Google Analytics and Google Maps API are integrated for analytics and mapping features. The site appears to be hosted under the REG-INTERNET-CZ registrar with DNS servers ns.forpsi.net and ns.forpsi.it. Performance is moderate with basic mobile optimization and accessibility features. SEO is basic with meta keywords and descriptions present but no advanced structured data or Open Graph tags detected. The CMS is not explicitly identified, suggesting a custom or proprietary solution. Technical debt is moderate, with opportunities to modernize the tech stack and improve security and privacy compliance.
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.
