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

ProSiebenSat.1 Welt was a German Pay TV channel operated under the ProSiebenSat.1 media group, offering entertainment content including TV programs, films, and series. The channel ceased operations at the end of 2023 after nearly two decades. The website serves primarily as an informational and redirect portal to partner channels and provides compliance and legal information. Technically, the site is built using modern web technologies including Next.js and React, hosted likely on AWS infrastructure, and uses Contentful as a CMS. However, the site suffers from a critical security issue: the SSL certificate is invalid or missing, resulting in no HTTPS support, which severely impacts security posture and user trust. No advanced security headers or TLS protocols are enabled, and DNSSEC is not configured. Privacy compliance is addressed with a privacy policy and cookie consent mechanism, but no direct contact information or incident response details are provided. Overall, the site is functional and professionally designed but requires urgent security improvements to protect users and maintain credibility.

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

  2. 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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 business operates in the media and telecommunications sector as part of the ProSiebenSat.1 group, targeting German-speaking audiences interested in Pay TV entertainment. The business model is subscription-based, relying on partnerships with cable and satellite providers. The channel's discontinuation suggests a strategic shift or market realignment. The website supports the brand by providing information and linking to sister channels, maintaining brand consistency and network cohesion. The lack of direct contact details or incident response information indicates a low emphasis on direct customer support via this site, likely relying on partner providers. The presence of compliance and legal links reflects regulatory adherence. The technical infrastructure is modern but security gaps pose risks to business credibility.

Security posture

The security posture is weak due to the absence of a valid SSL certificate and HTTPS, exposing users to potential interception and trust issues. The lack of security headers and modern TLS protocols further weakens defenses against common web attacks. DNS configuration is basic with SPF but no DMARC or DNSSEC, limiting email security and domain protection. No incident response or vulnerability disclosure information is available, indicating limited transparency and preparedness. Privacy compliance is adequate with a cookie consent mechanism and privacy policy. Overall, the site requires immediate remediation of SSL issues and implementation of security best practices to reduce risk and improve user trust.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Configure and enable HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable HSTS with includeSubDomains and preload to enforce secure connections.
  4. Implement DNSSEC and DMARC to enhance domain and email security.
  5. Publish clear incident response and vulnerability disclosure policies to improve transparency and trust.
Technical notes

Notes

The website uses a modern React-based framework (Next.js) with server-side rendering and static generation features. It leverages Contentful as a CMS and is hosted on AWS infrastructure. Performance is moderate with a page load time of approximately 5.2 seconds and 54 resources loaded. Mobile optimization is good with responsive images and viewport settings. SEO is supported by comprehensive meta tags including Open Graph and Twitter cards. Accessibility is basic but could be improved. The lack of HTTPS and security headers is a critical technical deficiency. The site uses external scripts for cookie management and polyfills for browser compatibility. Overall, the technical foundation is solid but security and performance optimizations are needed.
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.
