VPRO is a well-established Dutch public media organization offering a broad range of original and impactful content including TV programs, documentaries, podcasts, and events. The website serves as a comprehensive media platform targeting a general audience interested in cultural and societal topics. Technically, the site is built on modern frameworks such as Astro, integrates advanced video streaming via Mux, and employs analytics and error tracking tools like Google Tag Manager and Sentry. The site is performant, mobile-optimized, and accessible with a professional design and clear navigation. Security posture is strong with HTTPS and secure script loading, though explicit security headers and formal security policies are absent.

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

2 findings rated critical or high. Fix these first.

  1. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

VPRO operates in the media sector as a non-profit public broadcaster with a focus on innovative and original storytelling. Its business model revolves around content creation and distribution across multiple channels including TV, radio, and digital platforms. The organization maintains a strong market position in the Netherlands with a large audience base and a consistent brand presence. Key services include program production, event hosting, and newsletter dissemination. The company leverages partnerships with Dutch public broadcasting entities and maintains active social media channels to engage audiences. Growth indicators include a diverse content portfolio and integration of modern digital technologies. Strategic observations suggest opportunities to enhance transparency and compliance documentation to further strengthen stakeholder trust.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, asynchronous and deferred script loading, and use of crossorigin attributes to enhance security. No sensitive data is exposed in the HTML content. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options represents an area for improvement. There is no published security policy or incident response contact information, nor a vulnerability disclosure program or security.txt file. Privacy compliance is minimal with no visible privacy or cookie policies, though a consent mechanism is present. Overall, the site is secure but could benefit from formalizing security governance and transparency to meet higher compliance standards.

Recommendations

  1. Implement and publish explicit security headers including Content-Security-Policy and X-Frame-Options to mitigate common web attacks.
  2. Create and make accessible a comprehensive privacy policy and cookie policy to enhance GDPR compliance and user trust.
  3. Establish a formal security policy and incident response contact channels to improve security governance and readiness.
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance contact information by providing direct company emails and phone numbers for support and security inquiries.

Notes

The website is built using the Astro framework, leveraging modern JavaScript modules and advanced video streaming technology via Mux. It integrates Google Tag Manager and NPO Tag for analytics and tracking, and uses Sentry for error monitoring. The site employs best practices such as async and defer script loading and crossorigin attributes for fonts and scripts. Performance is optimized with responsive images and mobile-friendly design. Accessibility features are present, including skip links and semantic HTML. SEO is supported by comprehensive meta tags and Open Graph data. Technical risks are minimal, though the absence of some security headers and formal compliance documents could pose future challenges. Overall, the technical infrastructure is modern, performant, and well-maintained.
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.
