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

6 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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 a key media advertising office in Poland, leveraging its affiliation with Warner Bros. Discovery. Its business model centers on selling advertising inventory across multiple media channels, including TV and online platforms. The website links to several official partner portals supporting order management, content transfer, and invoicing, indicating a mature operational ecosystem. The target customers are advertisers and agencies seeking media exposure. The presence of comprehensive privacy policies and cookie consent reflects awareness of regulatory requirements. The company appears large in scale, with a clear brand identity and consistent messaging. No subsidiaries were identified, but the parent company is Warner Bros. Discovery.

Security posture

The website enforces HTTPS and employs cookie consent mechanisms aligned with GDPR, indicating a good baseline for security and privacy. However, no explicit security headers such as Content Security Policy or X-Frame-Options were detected, representing an area for improvement. No exposed sensitive data or vulnerable libraries were found in the HTML content. The site uses reputable third-party analytics and marketing tools, which should be regularly audited for security. There is no visible incident response or security policy information on the site, nor a vulnerability disclosure program. Overall, the security posture is good but could be enhanced by adding security headers and publicizing security policies.

Recommendations

  1. Implement and enforce HTTP security headers including CSP, HSTS, and X-Frame-Options to mitigate common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance accessibility features to improve compliance with accessibility standards and broaden user inclusivity.
  5. Regularly review and update third-party scripts and analytics tools to minimize security risks from external dependencies.

Technical notes

Notes

The website uses a modern technology stack including Google Tag Manager, Gemius analytics, and OneTrust for cookie consent, indicating a mature digital infrastructure. The site loads asynchronously loaded scripts and uses SVG graphics for icons and logos, supporting good performance and scalability. Mobile optimization is good with responsive design elements. SEO is supported by proper meta tags and Open Graph metadata. However, no CMS or hosting provider details were identified from the HTML. Performance is moderate, with potential for improvement by optimizing script loading and caching. Accessibility is basic and could be improved with ARIA attributes and keyboard navigation enhancements.
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.
