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

NPO.nl is the official public broadcasting portal of the Netherlands, operated by the NPO organization. It aggregates programs, documentaries, podcasts, and articles from various Dutch public broadcasters, serving as a centralized media platform for Dutch audiences. The website is well-established, with a domain age dating back to 1998, reflecting its long-standing presence in the Dutch media landscape. The portal targets a broad audience interested in public media content and offers a comprehensive range of services including streaming and content aggregation from multiple broadcasters. Technically, the website employs modern web technologies such as JavaScript, CSS, SVG, and lazy loading for images to optimize performance and user experience. It uses a custom content management framework (CCM) and integrates third-party scripts for cookies and advertising opt-out. The site is mobile-optimized and accessible, with good SEO practices evident in meta tags and structured navigation. Security-wise, the site enforces HTTPS with DNSSEC enabled, uses crossorigin anonymous scripts, and avoids exposing sensitive data, indicating a strong security posture. However, the site lacks explicit privacy and cookie policies in the provided HTML content, and no visible consent mechanism for cookies was detected. Contact information such as emails or phone numbers is not explicitly present in the analyzed content, which may impact user trust and compliance. There is also no visible security policy or incident response contact information. Overall, the site is professional, trustworthy, and secure but could improve transparency and compliance by publishing clear privacy, cookie, and security policies. The overall risk assessment is low, with recommendations focusing on enhancing privacy compliance, publishing security and incident response policies, and implementing explicit cookie consent mechanisms to align with GDPR and best 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

4 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 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

      Prevents clickjacking attacks

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

  2. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

  3. 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

Business profile

NPO.nl holds a strong market position as the primary public broadcasting portal in the Netherlands, aggregating content from multiple public broadcasters such as AVROTROS, BNNVARA, EO, HUMAN, KRO-NCRV, MAX, NOS, NTR, and others. Its business model centers on providing free access to public media content, supported by public funding and advertising. The portal targets Dutch-speaking audiences interested in news, documentaries, entertainment, and cultural programming. The partnership ecosystem is robust, linking to multiple broadcaster domains and social media channels. Growth indicators include continuous content updates and thematic collections. The company operates under the NPO umbrella, founded in 1998, and maintains consistent branding and high content quality. Revenue streams likely include public funding and advertising partnerships. Strategic observations suggest maintaining strong compliance and transparency will be critical to sustaining trust and regulatory alignment.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and DNSSEC enabled, reducing risks of man-in-the-middle and DNS spoofing attacks. The use of crossorigin anonymous scripts and absence of exposed sensitive data in the HTML further strengthen security. However, the lack of explicit security headers such as Content-Security-Policy or X-Content-Type-Options could be improved. No vulnerabilities or outdated libraries were detected in the provided content. The absence of published security policies or incident response contacts limits transparency and user confidence in handling security incidents. Compliance with GDPR is implied but not explicitly documented. Overall, the site is secure but would benefit from enhanced security policy disclosures and cookie consent mechanisms.

Recommendations

  1. Publish a comprehensive privacy policy page clearly accessible from the homepage.
  2. Implement and display a cookie consent banner/mechanism to comply with GDPR.
  3. Add explicit security headers such as Content-Security-Policy and X-Content-Type-Options.
  4. Provide clear contact information including security incident response and data protection officer details.
  5. Enhance transparency by publishing a vulnerability disclosure policy or security.txt file.

Technical notes

Notes

The website uses a modern and performant technical stack including JavaScript, CSS, SVG, and lazy loading for images, contributing to fast load times and good user experience. It employs a custom content management framework (CCM) and integrates third-party scripts for cookie management and advertising opt-out. The site is mobile-optimized and accessible, with semantic HTML and ARIA labels for navigation. SEO is supported by comprehensive meta tags and Open Graph data. No CMS like WordPress or Drupal was detected, indicating a proprietary or custom-built platform. Hosting provider details are not explicit but the domain uses DNSSEC and HTTPS, indicating a secure hosting environment. Technical risks are minimal, with opportunities to improve by adding security headers and formalizing privacy and security policies.
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.
