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

BigMedia, spol. s r.o. is a well-established leader in the Central European outdoor advertising market, specializing in a broad range of advertising formats including billboards, digital displays, and transport advertising. The company offers comprehensive services from rental to production and installation, targeting businesses and advertisers seeking out-of-home advertising solutions. Their market position is strong, supported by a domain registered since 2008 and active social media presence. Technically, the website employs modern JavaScript libraries and tracking tools such as Google Analytics and Quantcast Choice for consent management, indicating a moderate level of digital maturity. The site is mobile-optimized with good navigation and professional design. Security posture is adequate with HTTPS enforced and cookie consent implemented, but lacks explicit security headers and published security policies. Privacy compliance is partial, with cookie consent present but no dedicated privacy policy page found. Overall, the website is professional and trustworthy but could improve transparency and security practices.

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

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 operates in the media and transportation sectors, focusing on outdoor advertising in Slovakia and Central Europe. Their business model revolves around renting advertising spaces and providing production and consulting services for advertising campaigns. The target customers are businesses and marketing agencies seeking effective out-of-home advertising. The company demonstrates competitive advantages through its comprehensive service offerings and market leadership. The website reflects a medium-sized enterprise with consistent branding and a clear market focus. Partnerships or subsidiaries are not explicitly identified. The presence of social media links and terms of service documents adds to business credibility.

Security posture

The website enforces HTTPS and implements a cookie consent mechanism, which are positive security and privacy indicators. However, the absence of explicit security headers such as Content-Security-Policy and lack of published security or incident response policies reduce the overall security maturity. No vulnerability disclosure or security.txt file is present, and no direct contact information for security incidents is provided. The site does not expose sensitive data or show signs of vulnerabilities in the provided content. Overall, the security posture is moderate but could be significantly improved by adopting best practices and transparency measures.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear and accessible privacy policy page detailing data collection, processing, and GDPR compliance to improve privacy transparency.
  3. Add explicit company contact information including emails and phone numbers on the website to facilitate communication and trust.
  4. Establish and publish a security policy and incident response contact details to improve security readiness and customer confidence.
  5. Consider adding a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with libraries such as Owl Carousel and Google Maps API, enhancing user experience and interactivity. Google Analytics and Quantcast Choice are integrated for analytics and consent management, reflecting awareness of privacy regulations. The site is mobile-optimized and has a clear navigation structure. However, no CMS or hosting provider information is evident from the source. Performance is moderate with no explicit indicators of slow loading. Accessibility features are basic but present. SEO optimization is basic with meta tags and Open Graph tags included but lacking detailed descriptions or keywords. Technical debt appears low but could be improved by adding security headers and structured data for enhanced SEO and accessibility.
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.
