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

LED MULTIMEDIA s.r.o. operates the largest independent network of large-format LED screens in the Czech Republic, specializing in digital outdoor advertising. The company focuses on leveraging modern LED technology to provide high-visibility advertising solutions adaptable to various weather conditions and client needs. Their business model centers on owning and managing LED advertising spaces, offering clients flexible campaign options and comprehensive service support. The website reflects a professional and consistent brand image, targeting business clients and advertisers within the Czech market. Technically, the site employs modern web technologies including JavaScript libraries, Google Fonts, and tracking via Google Analytics, hosted on VAS Hosting infrastructure. While the site is mobile-optimized and well-structured, it lacks a dedicated privacy policy and explicit security headers, which are areas for improvement. Security posture is moderate with HTTPS usage and cookie consent implemented, but no published security or incident response policies. Overall, the domain registration data aligns well with the business claims, supporting legitimacy and trustworthiness.

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. 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

      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 holds a strong market position as the largest independent LED screen network in the Czech Republic, serving a diverse client base including notable brands. Their competitive advantage lies in owning all advertising spaces, enabling low production costs and flexible campaign customization. The business model is focused on outdoor digital advertising with revenue streams from advertising placements and campaign management. Growth indicators include expansion into all regional cities and ongoing client testimonials reflecting satisfaction. The partnership ecosystem includes technology providers and digital marketing tools, with no apparent subsidiaries or parent companies. Strategic observations highlight the importance of maintaining technological leadership and enhancing privacy and security compliance to sustain market trust.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled and a cookie consent mechanism in place. However, it lacks visible security headers such as Content-Security-Policy and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No incident response or security policy information is published, limiting transparency and preparedness perception. The absence of a privacy policy page reduces GDPR compliance confidence. No vulnerabilities or exposed sensitive data were detected in the provided content. To improve security posture, the company should implement comprehensive security headers, publish privacy and security policies, and establish clear incident response contacts.

Recommendations

  1. Publish a comprehensive privacy policy detailing data processing and GDPR compliance.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publish an incident response policy with dedicated contact channels.
  4. Regularly audit and update third-party libraries to mitigate vulnerabilities.
  5. Enhance transparency by providing data retention policies and cookie usage details.

Technical notes

Notes

The website uses a modern technology stack with JavaScript frameworks and libraries such as jQuery, Bootstrap, Swiper.js, and WOW.js for animations. Google Fonts and Font Awesome are used for typography and icons. The site is hosted on VAS Hosting as inferred from nameservers. Performance is moderate with deferred script loading and responsive design for mobile devices. SEO optimization is basic with minimal meta keywords and description tags. Accessibility features are limited but present. There is no indication of a CMS, suggesting a custom-built site. Technical risks include lack of security headers and incomplete privacy compliance, which could impact user trust 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.
