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

PULS 4 is a prominent Austrian media company offering a comprehensive TV broadcasting and streaming platform, integrated with the JOYN service. The website targets German-speaking audiences in Austria with a rich variety of content including live TV, series, news, and entertainment. The business operates under the umbrella of ProSiebenSat.1 Media SE, reflecting a strong market position in the Austrian media landscape. Technically, the site leverages modern web technologies such as Next.js and is hosted on Amazon CloudFront, ensuring scalability and performance. However, the absence of a valid SSL certificate is a significant security concern that undermines user trust and data protection. Privacy and legal compliance are well addressed with comprehensive policies and consent mechanisms. Overall, the site demonstrates a mature digital presence but requires urgent remediation of its SSL/TLS configuration to meet security 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

7 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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"

      • 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 company operates in the media sector with a large-scale presence in Austria. Its business model revolves around content broadcasting and streaming, monetized primarily through advertising and partnerships with platforms like JOYN. The website showcases a broad content portfolio, including live TV, on-demand clips, and user engagement campaigns. The integration with JOYN and use of reputable ad and marketing tools indicate a sophisticated ecosystem. The company maintains active social media channels and provides clear legal and privacy information, enhancing its credibility. The domain registration data aligns with the business identity, supporting legitimacy. Growth opportunities lie in expanding digital offerings and improving security posture to maintain user trust.

Security posture

The website's security posture is currently weak due to the lack of a valid SSL certificate and absence of critical security headers like HSTS. While other headers and policies such as referrer-policy and cache-control are present, the failure to enable HTTPS properly exposes users to potential interception and data tampering risks. No known vulnerabilities or malware indicators were detected, and the site does not appear to be behind a WAF or security challenge. Privacy compliance is strong, with GDPR-aligned policies and consent mechanisms. Incident response and security policy disclosures are not evident on the site. Immediate action is required to install and maintain valid SSL certificates and enable modern TLS protocols to protect user data and maintain compliance.

Recommendations

  1. Install and maintain a valid SSL/TLS certificate to enable secure HTTPS connections.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload options.
  3. Implement OCSP stapling to improve certificate revocation checks.
  4. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable legacy protocols.
  5. Add additional security headers such as Content-Security-Policy and X-Frame-Options.
  6. Publish a security policy and incident response contact information to enhance transparency.
  7. Regularly audit third-party scripts and advertising integrations for security and privacy compliance.
  8. Enhance accessibility features to improve user experience for all users.
Technical notes

Notes

The website is built using Next.js, a modern React framework, and is hosted on Amazon CloudFront CDN, ensuring good scalability and global reach. It integrates with JOYN for streaming services and uses marketing tools like Sendinblue and Brevo. The site is mobile optimized with responsive design and good SEO practices including Open Graph tags and meta descriptions. However, performance metrics were not available, and SSL/TLS configuration is critically lacking. The site uses chunked transfer encoding and caching headers to optimize content delivery. There is no evidence of a traditional CMS, suggesting a custom or proprietary content management solution. Overall, the technical infrastructure is modern but requires security improvements to fully support business operations.
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.
