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

VLTAVA LABE MEDIA a.s. operates a professional media and advertising platform in the Czech Republic, offering a variety of advertising formats across print and digital media. The website reklamy.vlmedia.cz serves as a portal for advertising clients to explore available ad formats and related services. The company maintains a strong market presence with a comprehensive media portfolio including newspapers, magazines, online platforms, and event services. The site is well-branded and targets advertisers and media buyers seeking effective advertising solutions. Technically, the website employs modern web technologies including Google Tag Manager for analytics and Didomi for consent management, ensuring compliance with GDPR regulations. The site is responsive and optimized for mobile devices, though some SEO and accessibility features could be enhanced. Performance is moderate with no critical technical issues detected. From a security perspective, the site uses HTTPS and integrates consent management tools, but lacks explicit security headers and documented security policies. No vulnerabilities or exposed sensitive data were found in the content. The absence of WHOIS data is likely due to privacy protection, which is common and justified for media companies. Overall, the security posture is solid but could be improved with additional headers and transparency. The overall risk assessment is low, with the site appearing legitimate, professional, and compliant with privacy regulations. Strategic recommendations include enhancing security headers, improving accessibility, and expanding contact information transparency to further strengthen 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

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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"

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 · found on this site
  • 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

VLTAVA LABE MEDIA a.s. holds a significant position in the Czech media market, leveraging a diversified portfolio of print and digital media assets. Their business model focuses on providing advertising solutions to a broad range of clients, supported by subscription services and event management. The company benefits from strong brand recognition and investor backing (Penta Investments). Their partnership ecosystem includes subscription platforms and distribution services, enhancing their market reach. Growth indicators include a modernized digital presence and active social media engagement. Strategic observations suggest continued investment in digital advertising formats and compliance frameworks to maintain competitive advantage.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS enforced and integration of consent management tools reflecting GDPR compliance. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options indicates room for improvement. No incident response or security policy documentation was found, which could impact readiness for security events. Data protection practices appear adequate given the privacy policy and cookie consent mechanisms. No critical vulnerabilities or exposed sensitive data were detected. Enhancing security transparency and implementing recommended headers would improve the security culture and posture.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish explicit security and incident response policies to improve transparency and preparedness.
  3. Enhance website accessibility features to comply with WCAG standards and improve user experience.
  4. Expand contact information availability, including verified company emails and phone numbers, to increase trust.
  5. Regularly audit third-party scripts and tracking tools to ensure no vulnerabilities or privacy risks.

Technical notes

Notes

The website uses a modern technology stack with Google Tag Manager for analytics and Didomi SDK for consent management, ensuring GDPR compliance. The front-end is built with Bootstrap CSS and custom JavaScript, delivering a responsive design optimized for mobile and desktop platforms. Performance is moderate with no critical loading issues detected. SEO metadata is present but could be expanded for better optimization. Accessibility is basic, suggesting opportunities for improvement. Hosting provider and CMS are not explicitly identified. Overall, the technical infrastructure supports the business needs effectively but would benefit from enhancements in security headers and SEO.
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.
